sodoraz Posted March 3, 2020 Share Posted March 3, 2020 Hi eveyone, I'm trying my first install of a MAC OS Catalina, on the laptop mentioned above. The installation panics almost imediately and I'm not able to see the dump logs. As I'm new to clover and all these tools, the only way I could think of in order to get the dump logs, was to film the screen when loading, but that's really time consuming. Is there any other way to generate these logs? Configurations: Intel i5 4310U CPU 2x8 GB RAM Intel HD4400 graphics. Thank you, Razvan Link to comment https://www.insanelymac.com/forum/topic/342839-catalina-installation-panic-on-hl-elitebook-840-g1/ Share on other sites More sharing options...
sodoraz Posted March 3, 2020 Author Share Posted March 3, 2020 (edited) Thank you for your reply. I'm already using the patches. I have managed to read the error message from one picture I took. It says ACPI Error: AE_NOT_FOUND. Could you please assist? The exact error message is: ACPI Error: [\SB_PCIO_LPCB.EC0_] Namespace lookup failure.

I have tried multiple ways of getting the installer to launch. Currently I'm still getting a panic message, as the attached screens show. Can anyone please help? EC should be patched.

sodoraz Posted March 10, 2020 Author Share Posted March 10, 2020 I managed to get passed this step. It turns out that on the G1, I don’t need to patch the EC, just rename it. The problem is that now I get the following error: devfs_kernel_mount failed: kernel mount failed 2 Link to comment https://www.insanelymac.com/forum/topic/342839-catalina-installation-panic-on-hl-elitebook-840-g1/#findComment-2711882 Share on other sites More sharing options...
