andreew75 Posted November 12, 2023 Share Posted November 12, 2023 Hello friends,I have a cosmetic issue when booting Opencore.Every time you boot Opencore, there are huge icons in the picker menu (image 1), while the system does not boot, but goes into reboot and only then the picker becomes normal (image 2). During any reboot, the picker always has normal icons, and after shutdown the computer and start after some time, the picker again has huge icons.Bios has been updated to the latest version. I have attached my EFI folder.I would be grateful for any advice.Asus Tuf Gaming Z590 PlusIntel Core I7-11700KAMD Radeon RX6600 Pulse config.plist.zip 1 Link to comment https://www.insanelymac.com/forum/topic/358037-opencore-picker/ Share on other sites More sharing options...
andreew75 Posted November 12, 2023 Author Share Posted November 12, 2023 eSaF, Thanks for the good advice! This seems to fix it with CSM enabled, but I need a few days to see how stable it is.

miliuco Posted November 12, 2023 Share Posted November 12, 2023 (edited) @eSaF @andreew75 CSM must be disabled in most cases to be able to work fine with macOS on UEFI PCs. CSM is a legacy mode not supported by default in UEFI Hacks. Can you boot macOS with CSM enabled?

Yes, I can boot MacOS with CSM enabled on UEFI only mode. Now this solved my problem stated above Spoiler Edited November 13, 2023 by andreew75 1 Link to comment https://www.insanelymac.com/forum/topic/358037-opencore-picker/#findComment-2813443 Share on other sites More sharing options...
miliuco Posted November 13, 2023 Share Posted November 13, 2023 @andreew75 I can't boot macOS with CSM enabled. Even NVRAM must be cleared and BIOS must be reset to be able to boot again.

miliuco Posted November 13, 2023 Share Posted November 13, 2023 @eSaF Your old brain works perfectly 😉 OpenCore Dortania's guide recommended disabling CSM in BIOS. CSM is supposed to be a legacy setting that older motherboards have and was the way to boot Windows 7. Its alternative is UEFI. However I see that some systems can (or even need to) boot with CSM enabled. This is not my case since with CSM activated macOS does not boot. You have BIOS CSM/UEFI Mode=UEFI, my understanding is that CSM is disabled and UEFI is enabled. 1 Link to comment https://www.insanelymac.com/forum/topic/358037-opencore-picker/#findComment-2813464 Share on other sites More sharing options...
Slice Posted November 14, 2023 Share Posted November 14, 2023 I can boot my first computer with or without CSM enabled in BIOS and see no differences. I just see more options in F12 boot choose menu. There is a question about starting Sonoma after legacy boot. I still not tested this. 1 Link to comment https://www.insanelymac.com/forum/topic/358037-opencore-picker/#findComment-2813466 Share on other sites More sharing options...
RobertX Posted February 13, 2024 Share Posted February 13, 2024 ...a little late to the subject...but, while in bios I enabled CSM (after always having it disabled) reboot and get various screen resolutions thru the boot process...ie: low res for bios, 1920x1080p@60 for Clover and apple boot screen ...then 3840x2180p@60 at login screen...I only mention this because Clover boot menu used to be 7xxx X2160p, a strange resolution any how...Slice said he saw no difference...this is one difference, for me(perhaps Csm enabled allows bios to read legacy vbios of gfx card) ...as to why I Enabled CSM, it was to check if any change with my video card(RX 570 8GB.) ...still testing Link to comment https://www.insanelymac.com/forum/topic/358037-opencore-picker/#findComment-2816849 Share on other sites More sharing options...
