-
Searching for macOS x.14 Mojave -
Searching for macOS ten.13 High Sierra
Hmmm… Searching for Mojave and High Sierra installers only bear witness combo and security updates.
ii. High Sierra Mac App Shop
No big deal, permit's go to the High Sierra App Store and search for Mojave and High Sierra installers.
-
I found Mojave -
High Sierra non institute 404
Ok, well we are getting a little closer it seems. Searching for macOS Mojave comes upwardly, nonetheless High Sierra is nowhere to be institute.
3. What happens if you have an old version of installer.app on your arrangement and want the latest version?
You now come across Mojave is there in the Mac App Store, just instead of
Subsequently clicking Open I am presented with this message above. As you tin can see the App Shop first searched my system and institute that I already have macOS Mojave installer.app. Notice that information technology searches all locations, not but the Applications binder where the installer app normally is stored. Information technology found the macOS Mojave Installer.app in a binder called exam.
Bully, we are gear up to go correct? Non really considering I have no clue what version this is. Looking at the creation date gives usa a pretty good inkling. MacOS Mojave was released on September
iv. How practice I check the macOS version number of Install macOS installer.app?
We have multiple ways of checking the version number and build number. The easiest way is to simply expect at the version number info from Get Info .
After checking the version number, I now know the macOS version is x.xiv.0. We tin observe the build number inside the actual installer.app but knowing the version number is usually good enough unless you need a specific hardware build.
5. Downloading the latest version afterward finding an onetime version.
I take macOS Mojave Installer.app on my system but it's outdated. I need the latest version. We now need to go the app store to bear witness the Download button instead of Open . Just shut the App Store, delete the old version of macOS Installer so re-open up.
I deleted the installer.app but the App Shop still thinks that I accept the installer. The button SHOULD switch to Download but didn't. If this happens over again just restart your Mac.
Perfect, afterwards restarting the Mac App Store can't find any version of the Mojave installer on your Mac so information technology at present shows you the download push.
6. The Mac you are using has to exist uniform with the macOS version y'all are trying to download.
We could not complete your purchase. This version of macOS x.14 cannot be installed on this figurer.
I STILL can't download Mojave because the Mac I'm trying to download it on is non compatible. All I desire to do is download macOS Mojave! I practice understand why Apple did this, they don't want a user to think they could install Mojave on a system that can't run it. Apple should take this ane step further and not evidence it equally available in the App Store. Or have the button say Non Supported .
seven. If Mojave is non compatible with my organisation, how do I download High Sierra 10.13?
How do I download macOS Loftier Serra 10.13? If searching Loftier Sierra in the App Shop comes up empty how can I download information technology? You lot have to visit the Apple Upgrading to High Sierra Support Page for the straight App Store link.
We are dorsum in the ten.13 App Shop, allow's endeavor to download again.
After clicking Download we finally go some action!
I have a pretty fast connection but not 5.3 gigabytes in three minutes fast. The download just finished let's see what the deal is.
8. The dreaded 22mb"Stub" installer.
This is what's known as the macOS "Stub" Installer. This is not the 5gb full installer nosotros are looking for it'south only 22mb! All this file will practise is start the installation only to download the full 5gb before beginning the install. You cant boot to this file or create a USB Installer from this pkg.
While the ten.thirteen App Store does not allow you to download the full High Sierra installer, it will allow you to download the total version of Mojave.
ix. The Mac App Store was redesigned for Mojave ten.14!
The App Shop was totally redesigned for 10.fourteen Mojave. The expect is pretty unlike from 10.thirteen'southward App Store. This is what the Mojave section looks similar in the new App Store.
The new design aligns the Mac App Store with the iOS App Store. The first hint is that the
-
The GET push starts the process. -
Sure you desire to download a 6gb file?
-
Demand Admin creds to start the download -
Profit
We are off to the races now! The first thing y'all will notice is that instead of downloading macOS Mojave Installer inside the App Store it opens Software Update. Software Update will search for the Installer and ask if you lot are sure y'all want to download the 6gb Mojave Installer. After clicking download you will get a new prompt for admin credentials to first the download (not to actually install however). After
10. Tin can I download Loftier Sierra in the new Mojave App Store?
Good news, the Total High Sierra installer will now download from the new App Store.
xi. The new Mac App Store has solved the dreaded 22mb "Stub" installer trouble.
The "Stub" download problem can be reproduced using 10.13 App Shop. Yet I tin can't seem to reproduce this on x.14. I have tried multiple machines. The "Stub" installer problem seems to be gone as long as y'all are using ten.14's App Store.
12. Mac App Store Errors
If yous get one of the following errors, follow wait at the adjacent section beneath.
- The requested version of macOS is not available
- This version cannot be installed on this computer
13. Review of which macOS versions you can download on Mojave & High Sierra depending on your Mac Version.
Subsequently all this testing, we know what can be download from the App Store. We likewise found out what can't download. After performing multiple tests with each OS you tin can download whatever newer version, the electric current version simply only ane Os behind. You will get a mixture of "The requested version of macOS is non available" or "This version cannot be installed on this reckoner"

In this article, I will talk a niggling scrap about the current state of Apple's Documentation. After that, I will evidence y'all 3 Undocumented x.14 Mojave fixes that tin help y'all as a MacAdmin.
Documentation, Documentation, and Documentation. Say it three times fast! MacAdmins merely want Apple tree to provide proper documentation for features, controls and security settings and Enterprise Fixes. In some cases, Apple provides excellent documentation. An example of this would be the T2 Security Chip Security Overview released in October of last year. In other cases when it comes to binaries like sysadminctl not and then much.
The best that I could notice was a document called "If you see authentication server errors when turning FileVault on in macOS High Sierra". This article does not even mention SecureToken. You can get a few nuggets of data past checking the sysadminctl binary options only sysadminctl doesn't have a human folio. I fifty-fifty performed a search on programmer.apple.com/documentation as you can see in the picture higher up. I will be writing about sysadminctl adjacent week. Maybe I can create a MacAdmins version of a sysadmincatl man page! Still when I search for "SmartCard" three documents bear witness up. SmartCard back up is a modest piece in the overall macOS pie, still has multiple documents! Side Annotation: Shout out to all my peeps in the MacAdmins.slack.com #SmartCard channel (most 5 people) 🙂
Documentation is getting better.
If you have been keeping track, Apple tree documentation is getting amend. If you look at the "What'due south new in the updates for macOS Mojave" page you will see a large number of fixes. Eagle eye MacAdmins will exist first to spot " Enterprise Content" , this is the stuff MacAdmins are interested in.
10.14.2
ten.14.three
x.xiv.4
Bank check out that kickoff one under ten.xiv.iv! As noted in my previous article, I fought to go that one stock-still since x.fourteen.0. It's really corking to see that fix go mentioned in the Enterprise Content area.
What do y'all mean undocumented fixes ?
Apple tree is constantly fixing things behind the scenes. MacAdmins proceed to file radars, phone call Apple Care, exam beta releases, submit feedback and submit Apple Enterprise Support tickets. Defects and bugs ARE getting fixed simply are not listed in Apple tree'south Enterprise Content listing. I am not totally sure why sure fixes do not make the list.
Maybe Apple wants to keep the list curt while focusing on the major fixes. I wish Apple would list more than of them, even if they posted them in an enterprise merely area. An example of this would be AppleSeed for IT. If you lot are office of an Enterprise or School yous tin can exist selected to join the program. I highly recommend joining if yous are not a fellow member already. You lot can read the FAQ about joining eligibility here. Inside you will find links to macOS beta downloads and beta documentation. Each beta release (Sometimes up to six releases per combo update) volition show what has been fixed between updates. This is nifty information for whatever MacAdmin to have so you tin stay on top of what's going on.
iii Apple Enterprise fixes included in 10.14.0 – 10.fourteen.4
1. macOS 10.fourteen Mojave can now provide FV2 Authenticated Restarts for Combo and startOSinstalls.
In x.14 macOS Updates and Upgrades are now able to perform Authorized Restarts. This characteristic was not an option in previous releases. This is a pretty big deal, especially for #MacEDU and Enterprise customers who take computer labs.
Previously if y'all installed a macOS update and the organization was FV2 encrypted it would restart simply STOP at the FV2 unlock screen. If you performed this update remotely y'all would lose control of the machine. Things get worse at FV2 login window considering firmware volition shut the Mac down after 5 minutes of inactivity. The same problem will happen when you first a macOS Upgrade. Y'all will be disappointed afterwards returning from lunch thinking the update is complete only to find the Mac turned OFF. Y'all and then ability the Mac back on just to find the installer has only started with twoscore minutes remaining. With x.14 if you kick off a combo update or macOS upgrade the installer will perform an Authorized Restart and y'all volition never become stuck at the FV2 prompt once again!
For startosinstall you just accept to store the mojave.app in a folder like /Users/Shared. Then kick information technology off with this command – sudo /Users/Shared/Install\ macOS\ Mojave.app/Contents/Resources/startosinstall –nointeraction The –nointeraction option will prevent license agreement message.
2. Installing software updates using the -R restart selection at the login window now properly restarts the Mac to the installer. (ten.xiv.4)
When Apple tree released the T2 security chip they also added additional options to the softwareudpate binary then it could handle BridgeOS updates. Installing a philharmonic update on a T2 Mac is now a multi-pace procedure. Using softareupdate step i remains unchanged, it volition download the combo update from Apple which in plow stores in /Library/Updates. For step two, the Mac reaches out to Apple tree'due south personalization service (gs.apple.com) verify the BridgeOS and philharmonic update. When the verification is complete you will accept a new folder in /Library/Updates called PersonalizedManifest.
You lot are automate the entire process by using sudo softwareupdate -iaR . Options -i will install the update, -a will download all updates and -R will perform an automated restart. The procedure works simply fine if you are the logged in user. If the organization needs to update the BridgeOS the Mac will shutdown and then will power dorsum on with the T2 Chip to install the BridgeOS update. If the system does non require a BrigeOS update the system will restart to the update installer. The trouble comes in if you attempt to automate the install from the login window using the softwareupate -R or –restart pick. Softwareudpate will run run through the procedure listed out above only to stop at the very finish and be unable to restart.
Once all your Macs are updated to 10.xiv.4, you tin can now use the -R restart for all situations. Softwareupdate tin now restart the Mac if it'due south at loginwindow.
3. 10.14 FV2 Authorized restarts can use the PRK (Personal Recovery Primal) again.
When 10.13 arrived y'all could no longer perform FV2 Authenticated restarts using the PRK (Personal Recovery Key). This feature was just apartment out cleaved. This previously worked in 10.12 Sierra and below. Notation: You could still perform an Authorized restart with your FV2 proper name and password. An case of a PRK Authorized restart would be if you are a JAMF Pro client and had a policy that installed a packet but it also required a restart. You could select the option "Perform Authenticated Restart" Jamf would then send a fdesetup authrestart using the PRK. The parcel would install and then the organization would perform an FV2 authorized reboot so the user did not have to enter in the password at the FV2 unlock screen.
10.12, x.11 & 10.10 – Works!
sudo fdesetup authrestart = Enter a password for '/', or the recovery key:
10.xiii – Doesn't work
sudo fdesetup authrestart = Enter the user proper noun: ( striking the enter fundamental to toggle Recovery Primal Entry) = Error: Missing user name. Error: Unable to restart (error = -54).
10.14 – Works again!
sudo fdesetup authrestart = Enter the Username: (again striking the enter key to toggle Recovery Key Entry) Enter the current recovery central:
I hope that at least one of the fixes I mentioned in this commodity helps you. In the futurity I would love to come across more documented Enterprise fixes listed in the philharmonic update patch notes. Until so though, I will proceed to document said fixes and let y'all know almost them when I can.
If you lot accept whatsoever questions or comments, delight feel complimentary to achieve out!
10.13 – Updated from 17G6029 to 17G6030 10.12 – Updated from 16G1917 to 16G1918
UPDATE 03/30/19 – Apple just posted a knowledge article on why they updated both security updates.
https://support.apple tree.com/en-us/HT209635
Two shout-outs in one day for @AnthonyReimer (@jazzace)! He installed the latest High Sierra Security Update and institute the build number had changed. I started to look into this and found that both Security Updates for both 10.13. and x.12 have been replaced with new builds. The original build number for the x.thirteen High Sierra 2019-002 was 17G6029. Every bit of two pm CST, the new build offered is 17G6030. Checking Sierra, the Build number also changed from 16G1917 to 16G1918. Apple (usually) does not update the .app installer with security update fixes when released so the installer builds remain the aforementioned. No word on yet on what was inverse in both updates.
Bottom line, if yous installed the previous update (17G6029) the new build (17G6030) will evidence as available. It would exist appropriate to deploy the updated Security Update.
T2 BridgeOS update
New Apple BridgeOS updates are also listed.
Annotation: After installing the new (17G6030) Security Update the iBridge version was not updated. iBridge should read 16.16.4507.0.0,0
To examine further I opened upwards BridgeOSUpdateCustomer.pkg and inside was the version number.
CFBundleVersion
16.16.4507.0.0
SUS Inspector
Check out SUS Inspector, it's a neat tool to view macOS updates.
Suspicious Package Inspector
Also check out Suspicious Package.app to see what is inside macOS updates.
Before we get started I'm am going to talk a little fleck about how macOS and Agile Directory work together. I volition also go into some history behind the built-in Advertising Connector. In the end, I volition explain the current problems we are having with Agile Directory Mobile Account countersign syncing and how Apple stock-still the event.
If your company or school uses Active Directory, you most likely use Mobile Accounts. To get Mobile Accounts to work you showtime accept to bind the Mac to Active Directory, once bound the Mac is now trusted. Yous tin can now log in with any Active Directory user and access to Global Groups, Kerberos and Directory Contacts.
Sounds bang-up right? It was!
Once you lot log in, the system caches your Advertising account to the local directory. If you then disconnect the Mac from the network you can still log and continue to work. When the time comes to change your AD password y'all could alter it on a 2nd Mac, a Windows device or even a Web Portal.
How did the Advertizement password alter piece of work?
If you changed your password on the Mac it would offset cheque if any countersign requirements are set at the domain level. If you passed the requirements the password would be immediately changed in Active Directory. The password would then modify at the local offline level of your Mac. If you changed your password exterior the Mac (Web Portal etc..) the organization would receive the password change the adjacent time you connected the Mac to the network and logged in. Y'all would then be promoted to Update or create a new Login Keychain.
Active Directory & FileVault 2
The Advertisement password modify arrangement inverse in 10.7 with the addition of FileVault ii. At present when you changed your password an actress step had to be performed. Once the countersign was changed in AD it would then alter the locally cached password and then had to sync that countersign down to your FV2 account. When you lot turned on your Mac, you could and then utilize the same password as your AD account to unlock the volume and start booting the arrangement. The Advertizing password sync arrangement worked pretty well from 10.seven all the way up to 10.12 Sierra. Users would sometimes have problems hither and there when the Mac dropped off the domain simply usually a rebind and would save the day.
ten.13, APFS and SecureToken
Apple tree introduced the adjacent-generation file system called APFS (Apple File System). We first got to test information technology out in ten.12 Sierra in beta form. APFS was standard for all SSD drive installations on ten.13 High Sierra installs. You could withal opt out with commands and spinning hard drives would still employ HFS. When 10.fourteen arrived APFS was standard across all hard drives. The introduction of APFS brought an added undocumented security characteristic chosen SecureToken. If you wanted to enable FileVault 2 you had to accept SecureToken enabled for said account. Yous could no longer you use the PRK (Personal Recovery Key) or fifty-fifty a local admin to add actress users to unlock the volume like you could with HFS. You lot have to grant the 2nd user a SecureToken before they could become an authorized CryptoUser. To get the token in the first identify you lot had to be the offset user logging into macOS at the SetupAssistant.
ten.13 was the start of syncing problems for Mobile Accounts.
The main problem with this new organisation was that the SecureToken organization was not tested. Mobile account users, in particular, had naught merely problems with this new system. From 10.13.0-10.xiii.3 Advertising Mobile Account password syncing to FV2 flat out did not piece of work. During this fourth dimension frame we had multiple loftier priority tickets in with Apple Enterprise Support. When 10.xiii.4 hit Apple finally fixed the issue and password syncing started to somewhat work again. I say somewhat because everyone still reported issues only at least it worked SOME of the fourth dimension now. 10.xiii nevertheless had problems when you changed the password off the Mac.
Enough of the history lesson, get to the ten.xiv problem!
In one case 10.14 hitting nosotros were hoping that the problems nosotros had on 10.13 Mobile Accounts would fixed. Unfortunately, we were wrong, way wrong. The problem worse when 10.14.0 released. How could it exist worse than 10.thirteen and how did miss the trouble in ten.14 beta? On ten.13 as I mentioned above we had to deal with of Mobile Business relationship syncing of FV2 passwords. The user would change the password outside the system and it would non make it down to FV2. The good thing is we actually have set for this!
The following instructions volition change or Sync the countersign for the CryptoUser account that belongs to the AD user. This will only work if the user KNOWS the old password since the command will prompt for the current password.
- one. diskutil apfs list (Grab the disk label for Volume Macintosh HD unremarkably disk1s1)
- 2. sudo fdesetup list -extended (grab the UUID of the OS USER) You can also use diskutil apfs listCryptoUsers /
- 3. diskutil apfs changePassphrase disk1s1 -user UUIDhere (add together in the UUID of the OS USER from the pevious command and put it in UUIDHere.
That's cool, just you however haven't told usa why is the situation worse in 10.14?
The local cached offline password is never changed!
The problem is the outcome is undetectable UNTIL the user attempts to authenticate OFF the network. When they endeavour the current password information technology will Not work. They volition then have to call the helpdesk, who then changes the Advert password making the state of affairs fifty-fifty worse. This is the state of affairs for x.fourteen.3 and below.
- When connected to the network = Current Advertisement Password works!
- When Disconnected from the network = ONLY previous countersign works.
- FV2 password = Previous Countersign.
Things go fifty-fifty more annoying is if the user actually uses the old password to authentiate the Screen Saver while offline. The system will have the password but and then immediately prompt the user to unlock the Login Keychain. This is due to the keychain being set to the current AD password. Y'all would exist in a never-ending keychain countersign bicycle.
Do yous have a fix for the offline sync issue?
The good news is we practise, as long as you have a SecureToken enabled Admin user. All you demand to practise is turn off SecureToken and and so turn information technology back on. Something in this arrangement will then sync the offline cached password. Shout out to @annemacro on MacAdmins Slack for figuring this out!
- sudo sysadminctl -secureTokenOff useraccount -password – -adminUser adminuseraccount -adminPassword –
- sudo sysadminctl -secureTokenOn useraccount -password – -adminUser adminuseraccount -adminPassword –
Now that 10.fourteen.4 is out the countersign sync mechanism now working. As long as yous update systems to ten.fourteen.4 before users modify their AD countersign they will not take this outcome going forward. I take not had the chance to actually test the 10.xiv.4 update on a system that is already out of sync. The good news is that even if information technology doesn't fix the upshot when it is already happening you now take the tools to fix it yourself. The next time the user changes their password they will not experience the issue.
Why did this take so long to prepare?
The answer to this question is pretty simple. Everyone missed the bug from beta ane all the manner through into 10.14.0. I performed hours and hours of testing in beta. I was so concerned about that the FV2 password did not sync that I did not even recollect to examination the offline password. Even worse, neither did anyone else including Apple tree. It was not until around 10.14.2 when I had an enterprise ticket in with Apple and finally got a response.
"This bug will not be fixed until the next release of macOS"
When I read the reply to this support ticket I was in complete shock. Are yous going to tell me that we are going to flat out have a Not FUNCTIONING MOBILE Business relationship System FOR THE ENTIRE 10.fourteen RELEASE? I could not believe it. The Apple Enterprise Support Engineer I was working with also agreed and he was fantastic to work with and helped work through the issue with me. At this point what else would a #MacAdmin practice but Rant in MacAdmins Slack!!! The best way to do this is to certificate and explain the issue to others. Yous tin can then rally other MacAdmins to file Enterprise tickets or Radars. This will draw attention to the outcome and generate heat within Apple Enterprise Support. In the finish that's exactly what happened. We were non the only company that Used Mobile accounts. Those same companies permit Apple tree know that we needed a fix ASAP. Apple realized this was important and fixed this result for u.s.a. in x.14.4. (Thank you Apple tree!)
Where does that leave Mobile Accounts?
Before 10.13 Mobile Accounts worked very well. We had thousands of Macs connected to AD utilizing Mobile accounts and did non have any problems. One time 10.thirteen hitting things started to go downhill. The problem is, it seems similar Apple is not spending enough time on Mobile Accounts. The MacAdmins community has started to realize this and starting at the end of 2017 and into 2018. This began what I call "The great Mobile Account exodus to Local Accounts". NoMAD and Enterprise Connect make using local accounts while still having the ability to utilise Advertizing resources piece of cake. Mobile Accounts nonetheless serves information technology'due south purpose merely it seems the writing is on the wall.
Cheers
