나수환 Posted August 3, 2020 Share Posted August 3, 2020 In this page, Big Sur prebuilt images are for skylake and newer However, I have a broadwell laptop. So I can't use this image And I have sucessfully installed macOS Catalina in my laptop. Wanted to go to Big Sur Beta. So I tried to make a bootable USB, set up kexts etc But failed. When I boot from usb, it shows me black background white text. And there is no progress for an hour. So my question is, Are there no support for Broadwell and older CPUs? v Quote Link to comment Share on other sites More sharing options...

Do u have any plans to make prebuilt olarila image of big sur in broadwell or older systems? 2. My laptop is broadwell. Can I use the premade EFI folder which you made for Haswell?  Edited August 5, 2020 by 나수환 Quote Link to comment Share on other sites More sharing options...

kokelunas Posted November 13, 2020 Share Posted November 13, 2020 I installed successfully big sur release candidate 2 in my laptop Dell with core i5 broadwell processor. I haved the same issue in boot, only used the premade EFI folder for skylake and added my ssdt, dsdt, kexts and config.plist i used in Catalina.
