How does apple's EFI compare to the UEFI standard? Apple's EFI in macs were the first implementation of EFI by Intel but then Intel revised their work and made UEFI for PC's which is newer and possibly better. I wanted to know if Apple's EFI has been receiving updates through the years or is it outdated compared to UEFI ?
The Apple EFI firmwares are always automatically updated when you update the version of an OS or upgrade the OS. You can check it: https://support.apple.com/en-us/HT201518.
