dsalsa Posted September 6, 2021 Author Share Posted September 6, 2021 Thanks for the reply I tried an update in the past but I think it was with another version of macOS but I’ll try it I was really looking to install High Sierra on another drive, but I guess I can install Sierra on that other drive and then upgrade it once again, thank you Link to comment https://www.insanelymac.com/forum/topic/348765-need-efi-to-install-high-sierra-1013-on-a-sony-all-i-one/#findComment-2765771 Share on other sites More sharing options...
dsalsa Posted September 6, 2021 Author Share Posted September 6, 2021 just tried to upgrade my system from Sierra to High Sierra. Got this message. "To install macOS High Sierra, a firmware update is required." Attached is a screen shot. Any assistance on what I should do next would be appreciated.

Guest 5T33Z0 Posted September 6, 2021 Share Posted September 6, 2021 (edited) Open your config in Clover Configurator, go to SMBIOS and select "Update Firmware only" and then select a model closest to your CPU from the dropdown menu. Save Config and reboot and try updating macOS again. Otherwise Upload your current EFI please. Is it a Notebook?

dsalsa Posted September 6, 2021 Author Share Posted September 6, 2021 I'm using Clover Configurator version 5.18.3.0, as you can see from attached picture I don't have the "Update Firmware Only" option.

Guest 5T33Z0 Posted September 13, 2021 Share Posted September 13, 2021 (edited) @dsalsa Could be a bug Create a new, empty empty file Open the Dropdown menu right next to the missing text (should still work) Select the same mac model you are using in your config Copy the newly generated data from the following Sesctions and their fields to your config: Bios, Board, Firmware Save, Reboot, try installing HS again.
