zazman Posted December 18, 2020 Share Posted December 18, 2020 (edited) Hello, I have an issue at reboot after launching Big Sur 11.1 install from Catalina 10.15.7, it seems my Radeon RX560 causes it. Reboot goes a little further when I check "inject. ATI" in Clover (5127) config options, but in any case, boot stops before to reach second step of install gauge. No real error message when boot stops before to reboot, last lines speaking of Applekeystore error but not sure if my trouble has to do with this... I add my CLOVER folder, my clover config.plist isn't really optimised, I think I used the one I having in my notebook and it certainely could be cleaned, but not sure how. Maybe my SMBIOS config is too old for Big Sur ? (iMac late 2012) Can you please help me to fix this issue with my graphic card and advice me how to optimize my config.plist file and maybe clean/update extensions too. Best regards CLOVER.zip Edited December 18, 2020 by zazman Link to comment Share on other sites More sharing options...
chris1111 Posted December 18, 2020 Share Posted December 18, 2020 I have also Sandy Bridge Dell Optiplex 790 i5 2500k with an GT 710 I am not able to install BS but if the SSD is already made its boot very well Clover and OC If you find the way to install BS on that kind of machine let me know Link to comment Share on other sites More sharing options...
zazman Posted December 18, 2020 Author Share Posted December 18, 2020 Ho, do you mean you installed BS on your SSD from another machine ? I will let you know how it goes for me but unfortunately for me, my SSD drive is a micro SSD card on my motherboard, not a SATA drive so no chance for me to install BS from my notebook Link to comment Share on other sites More sharing options...
chris1111 Posted December 18, 2020 Share Posted December 18, 2020 Yes I mean installed BS from another Mac or Hack I try since the beginning of BS Beta 1 to install from USB and no luck here I don't know about the micro SSD ? Link to comment Share on other sites More sharing options...
zazman Posted December 18, 2020 Author Share Posted December 18, 2020 I mean, I have no other computer with a port for microSSD, the Z68XP-UD3 MB has one and I noticed it works faster than an internal SSD SATA3 drive. 1 Link to comment Share on other sites More sharing options...
mickeyd453 Posted December 19, 2020 Share Posted December 19, 2020 @chris1111 Your problem is that you do not have native NVRAM and so BS will not install - you can avoid this by installing on a machine with working NVRAM and transferring the drive over or you can use the following method if that option is not available to you. 1 Link to comment Share on other sites More sharing options...
chris1111 Posted December 19, 2020 Share Posted December 19, 2020 tanks but its not work here, I have a NVRAM.plist working and same reboot at the Count Line on USB install Big Sur I will try Updating from Catalina Link to comment Share on other sites More sharing options...
mickeyd453 Posted December 20, 2020 Share Posted December 20, 2020 based on that it sounds like you have legacy NVRAM working, not native NVRAM 1 Link to comment Share on other sites More sharing options...
zazman Posted December 21, 2020 Author Share Posted December 21, 2020 @Hervé Thank you for your informations about my MB and Msata SSD drive ! It wasn't my question here in fact So, what about my config and native NVRAM ? The answer of mickeyd453 was for chris1111 but not sure if it's right for me too ? Can you tell me please about my hardware and about my clover folder and config.plist, even with Catalina installation? Link to comment Share on other sites More sharing options...
