I have a late 2015 i7 iMac which has been causing me problems with running slow, the spinning wheel of death etc. I read in MacFormat magazine that a possible issue was the updating of firmware for this model of iMac. I checked and it is out of date
Mac model iMac17,1 EFI version found 170.0.0.0.0 ❌ Need to update EFI firmware MacRumours Forum has a thread <https://forums.macrumors.com/threads/imac-17-1-retina-5k-27-inch-late-2015-efi-firmware-update-failures.2228324/> on this very problem, but still unresolved. There is an article here https://eclecticlight.co/2019/10/08/which-efi-firmware-should-your-mac-be-using-version-4/ Unfortunately I don't understand what if anything I can do to update the EFI version. Any advice? Thanks Martin -- You received this message because you are subscribed to the Google Groups "Sussex Mac User Group" group.
