You can find a full list of supported Macs in the Rocket Yard guide: The lone exception is the 2010-2012 Mac Pro, whose graphics cards don’t meet Catalina requirements. Supported Macs: Most Macs from 2012 or later support macOS Catalina. The two primary causes are attempting to install on a Mac that Catalina doesn’t support, or trying to install Catalina on a Mac with limited storage space. It may be that the installation won’t start, it seems to freeze during the installation, or it never seems to complete. This is the most basic of Catalina installation errors it simply won’t install. With backups out of the way, let’s take a look at some of the common and not-so-common macOS Catalina installation issues you may run into: macOS Catalina Won’t Install If you need a storage solution to handle your backups, Other World Computing has a large selection of storage options you can choose from. If it does get your Mac going again, remember to back up your Mac before you go any further.

Installation will continue, or you will boot into the OS or get the Recovery Utilities menu (where macOS can be reinstalled from or Disk Utilities run). If the recovery partition isn't present and valid, these instructions won't work.Ĭlick the 2nd entry, you should see (and then click):
If the 2nd partition isn't the recovery partition, look under the paths in the list to see if one of them is it. The second PCI path is probably to the recovery partition, the one you need to boot from. The first PCI path in the list is probably the boot partition that doesn't contain bootable firmware. You should see two entries in a list (they are cryptic looking PCI bus paths). Select Boot Maintenance Manager and click. You'll be brought into an EFI text-mode GUI.

Your immediate objective is to help EFI locate and execute os-specific boot firmware. However, assuming you have a macOS recovery partition on that disk, it should contain a copy of boot.efi (macOS-specific boot firmware) that you can boot into the OS with. UEFI requires intervention because EFI firmware on the Mac's motherboard cant find valid OS-specific EFI boot firmware in the standard location on disk.
