Trying to update an older MacOS
Posted by: voodoopenguin

I have a late 2015 21.5" iMac running 10.11.6 El Capitan. According to Mactracker this computer should be capable of running 12 Monterey however Software Update doesn't show any sort of MacOS update. I've been scratching my head trying to work out why and then thought maybe it's because it requires an APFS HD as I know that at some point that was going to be necessary. I reformatted an external HD using APFS with the idea of cloning across to it then reformatting the internal to APFS and cloning back again. Unfortunately the iMac cannot see the external drive. It's a partition with two others and they show up but they aren't APFS. Bit of a Catch 22 situation where it should be able to run a later system but only if it is on APFS but does not recognise HDs that use that.

Any thoughts good people?

Update the OS to High Sierra/Mojave for the AFPS conversion and firmware updates first.

Same thing here, also on El Cap. Unfindable in app store.
But try following the link on this page (open with App Store.)

I would think those components would also be part of any subsequent OS version update. There's no way Apple would permit a Sierra user to install a Big Sur upgrade without having included those components.



It is what it is.

10.11 needs HFS and won't see APFS vols.

Erase the external as Mac Os Extended (Journaled) and clone to it and then test to confirm that it will boot.

...For so big a jump (from 10.11 to 12), you should have *at least* one backup anyway.
