jman69 Posted May 22, 2020 Share Posted May 22, 2020 I'd like to install Catalina on a E6230 with BIOS A20 using recommended settings, using the Catalina instructions here: The target disk is an empty SSD. The installer boots but after about 1m it automatically reboots I've tried using the recommended and latest Clover. How to fix this / get info about what's going on (I see a lot of -v messages flash by but it's too fast to figure out what's happening just before the reboot). Thanks!

Administrators Hervé Posted May 23, 2020 Administrators Share Posted May 23, 2020 If you're installing 10.15.4, that's normal because my pack contained an XCPM-enabled Clover config. 10.15.4 breaks this as stated in our article about the update. You need to revert to good old SSDT-based power management method using the attached config + your CPU-specific SSDT generated using Pike R Alpha's well-known script: config.plist.zip The guide has just been amended to that effect.

jman69 Posted May 26, 2020 Author Share Posted May 26, 2020 Using latest Clover r5118, OSX 10.15.4 and E6230_Catalina_Clover_Pack_#2.zip https://osxlatitude.com/applications/core/interface/file/attachment.php?id=27197. System matches specs on install guide, except 16GB RAM instead of 8. Crash: Edit: also tried to install with an older Cataline version (10.15.2), same result.
