Moderators Jake Lo Posted December 4, 2019 Moderators Share Posted December 4, 2019 Try removing AppleBacklightFixup.kext and AzulPatcher4600.kext, both have been superseded by Whatevergreen.kext. Quote Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted December 5, 2019 Moderators Share Posted December 5, 2019 After the reboot, do you get any error message when you log on? Quote Link to comment Share on other sites More sharing options...
kali2000 Posted December 5, 2019 Author Share Posted December 5, 2019 No, that's the strange thing. Exits from sleep and after a few seconds it restarts. After I can log in normally. Quote Link to comment Share on other sites More sharing options...
kali2000 Posted December 5, 2019 Author Share Posted December 5, 2019 Ok ... I've already found what the issue was. The restart is caused by AppleALC, It is a widespread issue in Haswell. Here they give detailed information and how to fix it, for the moment. I hope the issue is solved in future AppleALC updates. Thanks a lot of for your help...
