Open Jaden-mcpi opened 3 years ago
i have a mac mini late 2014 that this morning got updated to 11.1 but my mid 2012 doesn't show the update... anyone more with this problem?
Unsupported machines will not be allowed to use OTA upgrades by Apple servers unless you use some additional cloaking technology (opencore). So the missing update with your currently unsupported mid 2012 is not an issue - it is works as designed by Apple. You will have to upgrade by getting a full installer, put it onto an USB, patch the installer and reinstall and patch the installed system.. This is the normal way to do it. BTW the last OTA updates (to 11.1 and to the next 11.2 beta) have the size of a full installer. There is nothing to save using the OTA right now. And it is slower - went through both types two days ago on the same system type. The stock installer will not boot your 2012, too. Works as designed by Apple and therefore it has to be patched.
@Ausdauersportler However, 11.2 is in the public beta, and does not yet have an InstallAssistant.
That happened before with other public beta versions, too. Unless Apple does not provide a full installer there is only one (opencore) way right now with all the problems.
@Ausdauersportler Would I have to format the disk in order to use opencore and install the update, or could I do it from my system currently installed with the patch?

There are several ways to use opencore...please read the online doc to get a better idea.
This is experimental and you should do this only if you can save your firmware in advance and you are sure you can flash the saved firmware back using a clip programmer if something is going south.
Installing OpenCore has become an option with this new update. Following the docs you can install a preconfigured version of opencore using install-opencore.sh
on your USB installer to just to boot some formerly unsupported Macs (iMac 11,x, MacBookPro6,x) and to install or you can use the config-opencore.sh
to install a basic OC version enabling OTA (assuming you have already a patched installation of Big Sur. Just boot into the EFI Boot partition of the USB installer and using the boot screen boot into Big Sur. OTA should be enabled.
After OTA upgrade you need to patch the system and this can be done now only from the booted Big Sur.
This is experimental and you should do this only if you can save your firmware in advance and you are sure you can flash the saved firmware back if something is going south.
This OC will spoof the iMacPro1,1 ID which is optimal for all iMacs Late 2009 to Mid 2011 and all MacPro systems using new AMD GPUs. I might not be the best choice for all systems.
When l tried to update the Mac as the macOS bigger installer asked me to update my Mac but it failed. What should l do?
