mottvlk Posted July 3, 2021 Share Posted July 3, 2021 Hello, I recently installed Big Sur on my hp probook 650 g1. Everything works perfectly But, unfortunately I have no sound and when I connect the display port cable, laptop restarts. I would appreciate it if someone could take a look on my efi file. Thanks in advance. HP Probook 650 G1, Core i5-4210M @2.60GHz/HM87, 8GB DDR3-1600, [email protected] EFI.zip Quote Link to comment Share on other sites More sharing options...
