Hi all,

just downloaded the 10.4.3 combo update and surprise the installer reports the error:
Code:
macOS 10.14.3 Update can't be installed on this disk. This Mac can only install macOS on APFS-formatted drives.

how the hell can they really release such an update? Just force APFS filesystem during the installation instead...

As a matter of facts I was sure that my drive was formatted in APFS during installation and now I find out in the worst way that this has not happened. So I'm stuck with the buggy 10.14.2 forever? :eek:

No way to have an hot- and on-the-fly conversion from Mac OS Extended (Journaled)? I have to clone and format, right? WTF :apple:! :mad:
 
This appears to be an Apple issue. I tried to install the combo updater and received the same message. All my disks SSDs (APFS) and HDDs (HFS+) were flagged with the "can't install" icon. Apparently you can use the regular updater. But if you want the Combo, I think the only way is to wait until Apple resolves this.

Looks like we could have more bugs incoming... maybe I'll stay on the safe side and wait a few weeks before updating the OS.

Thanks for your replies guys ;)

Go to Disk Utility, select your boot drive, and Click Edit > Convert to APFS Volume. APFS on the boot drive is a requirement of Mojave, and while there are workarounds they are most certainly not guaranteed to work on subsequent OS updates.

Unfortunately, but comprehensibly, I can't do that on the boot drive (the option is greyed out). I have to boot from a secondary drive. Thanks for the suggestion!
 
No EFI-compatible graphic card here :(
The problem is not that your drive isn't APFS. Apple had inadvertently forgotten to allow 10.14.2 to use the combo updater. They have posted a new version on the support website which fixes this. (or you can run the delta updater without a problem.)
 
Software update doesn't even find it!
...I should redownload the delta/combo updater but as I already wrote I'll wait a bit to see if they will release a less buggy updater :D
 
You could also get yourself an 8GB USB stick for less than $10 and make a USB installer.
