MorenoAv Posted July 7, 2020 Share Posted July 7, 2020 (edited) Installing finally and the secret is reset nvram not clear nvram, that solves it ... no more SIGBART and it boots... 26 minutes remaining but is painfully slow... But now I have this problem see the picture below anyone now how to solve this? After the second photo is a never ending reboot loop ...

mnfesq Posted July 7, 2020 Share Posted July 7, 2020 24 minutes ago, fabiodelra said: @DarkNeptune0 The same I had this problem and found that it was the result of one of my quirk settings in OC config.plist. I wish I could be certain which one it was but I never just make one adjustment at a time because I don't have the patience to reboot that many times before getting a working config. Here is the working config for my USB installer. Please remember that I have an HP laptop so there are some quirks specially-selected for that (i.e., LAPIC kernel panic, and UnblockFSConnect.). Also, I stripped the SMBIOS info except the Mac model. Maybe it will help you. config.plist-USB Installer.zip Link to comment Share on other sites More sharing options...

DarkNeptune0 Posted July 7, 2020 Share Posted July 7, 2020 @fabiodelra Right now I'm going to try to upgrade to beta 2, but you can try the config.plist of @mnfesq by searching the internet maybe you could use to add these two acpi patches : change H_EC to EC 485f4543 45435f5f change ECDV to EC 45434456 45435f5f Link to comment Share on other sites More sharing options...

iCanaro Posted July 7, 2020 Share Posted July 7, 2020 (edited) PS: Ops sorry, forgot the spoiler.... but I meant I don't approve of the deletion of the thread on beta 1 It will also be beta, for those who know how to grasp them, certainly not those who want the ready gruel, there was a lot of useful information. but perhaps the reason for the deletion of the thread, is to be attributed to the many who do not abide by the rules Edited July 7, 2020 by iCanaro Link to comment Share on other sites More sharing options...
