esmith1966 Posted November 5, 2021 Share Posted November 5, 2021 Has anyone attempted an install to this laptop? My efforts so far have not been successful, I have not even been able to get it to the install screen. Just checking if anyone else has attempted this. I know there is a graphics card support issue.

Administrators Hervé Posted November 6, 2021 Administrators Share Posted November 6, 2021 You have to use a supported SMBIOS (relevant Haswell/Broadwell/Skylake model minimum). The HD4000 patch will be required post-install. I had tried Monterey beta on my E6230 and it had many issues like overall lag (despite HD4000 patch), high CPU usage and high T°. Best avoided imo.

ICEGalaxy Posted November 7, 2021 Share Posted November 7, 2021 Same here on a Skylake i5, I had high CPU usage, Fans at maximum, heating and battery issues... but Stable Monterey is 10 times better than the Betas, I just updated successfully today and all those problems disappeared. so maybe it's the OS fault and not the unsupported graphics, I'm just saying :-1 Link to comment Share on other sites More sharing options...
Administrators Hervé Posted November 8, 2021 Administrators Share Posted November 8, 2021 I’ll try and have a go at it again; on my ToDo list among the many other things I need to do with Monterey. Link to comment Share on other sites More sharing options...
esmith1966 Posted November 8, 2021 Author Share Posted November 8, 2021 ICEGalaxy Can you post your install USB EFI? I can try it here on my machine... Link to comment Share on other sites More sharing options...
ICEGalaxy Posted November 10, 2021 Share Posted November 10, 2021 @esmith1966 I have a Skylake (6th Gen Intel Core) machine but you can try mine. I removed the WiFi and Bluetooth Kexts, I also removed the Audio layout ID on AppleALC.kext (boot flag) as idk yours, changed the SMBIOS to match yours, and added "-no_compat_check" as a boot flag, although I think these changes aren't enough, but you might just try EFI.zip also, you need to patch the graphics as the 4000 isn't supported as Herve said Link to comment Share on other sites More sharing options...
esmith1966 Posted November 12, 2021 Author Share Posted November 12, 2021 the EFI hung at a certain point... It was a long boot process... Will get pictures when I attempt this again... (needed to use the machine) Link to comment Share on other sites More sharing options...
