Nimm die EFI von hier
İst wohl Catalina 10.15.4 Approved https://github.com/tlefko/XPS13-9350-Catalina
Hey guys, was scrolling thru the forums and saw this (sorry don't speak German) -- if you guys need any help with my EFI feel free to send me an email or a forum message. I recently updated it to Big Sur. I also have the PM951 SSD. Glad I could support the community
