MacNB Posted September 17, 2023 Share Posted September 17, 2023 Ventura on the unsupported Mac mini4,1 S/W failed with "failed to prepare the software update" when trying OTA Incremental Update. Using OCLP 0.6.8 (OpenCore 0.9.2): OCLP EFI posted here Original S/W update offer was full update...~12GB. So, I reverted Root Patches and rebooted. On restart, S/W was now 475MB...yeh Incremental Update: After Downloading, the preparing stage start and at ~ 20 minutes left I get : Setting SecureBootModel=Default still failed but given a different message: Disabling RestrictedEvents kext make no difference. Booting in Safe Mode offers no updates at all I have not tried the Full update yet but expect no issues as the previous Full updates were applied successfully. It's not a problem as I have a fast internet connection to download the Full Update but any insights ? Link to comment Share on other sites More sharing options...
Cyberdevs Posted September 17, 2023 Share Posted September 17, 2023 @MacNB In my case when the Screen Saver activates it will always result to update failure, make sure Screen Saver is disabled during the update or simply don't let it get activated.

MacNB Posted September 17, 2023 Author Share Posted September 17, 2023 @Cyberdevs Thx for the suggestion. Turning OFF the screen saver and not letting it get activated did not make any difference. Turning OFF the vmm kernel patches did make difference.....no Updates available at all. Seems similar to issues with RSR updates that not supported by OpenCore on pre-Haswell systems. 1 Link to comment Share on other sites More sharing options...
Cyberdevs Posted September 17, 2023 Share Posted September 17, 2023 @MacNB Same thing happens on my 2011 iMac (iMac12,1) with macOS Sonoma and OCLP 0.6.9 1 Link to comment Share on other sites More sharing options...
