My system is running very smooth everything works apart from Apple TV, it shows the trailers but not my Apple movie collection, no problem in Catalina on that score, but it is early days for Big Sur. Apple TV + should work if you use iMacPro1,1 SMBIOS 1 Link to comment Share on other sites More sharing options...

MorenoAv Posted July 7, 2020 Share Posted July 7, 2020 How did you solve your SIGBART issue @dannyboy9 ? In that order do you guys, removed your working ssd's to install from usb or not? Link to comment Share on other sites More sharing options...
eSaF Posted July 7, 2020 Share Posted July 7, 2020 @justin Justin - Thanks for letting me know, my problem is I have it working perfect on Catalina using an iMac model 19.1 so was loathed to change to a different model just for Big Sir. Who knows maybe I will change Mac model later at official release if I am still having a problem but thanks, appreciate the feed back. Link to comment Share on other sites More sharing options...
dannyboy9 Posted July 7, 2020 Share Posted July 7, 2020 3 hours ago, dannyboy9 said: SOLUTION TO SIGABRT: Before I get there, here's a little backstory. I was a clover user until big sur and really wanted to try OC, big sur came and so did the opportunity. Tried to be over smart and make a OC folder directly and paste it into EFI without resetting or deleting any past variables. It did work successfully into Big Sur BUT those variables would come to bite me when I chose to install from an external media. So the solution is to keep whatever your virtualsmc and whatever kexts you already have, reboot into the pendrive and in OC menu, tap on RESET NVRAM. Tiny reboot by the system and you will see nothing into your boot menu, just opencore. Hit that and then when you come in OC menu, hit on install MacOS Beta. And doodah you are in the installer! @corint1 1 Link to comment Share on other sites More sharing options...

If the hardware you are talking about is the same as described in your signature, then, you may want to use a mac model that does not have iGPU, e.g. iMacPro1,1 or MacPro7,1 1 Link to comment Share on other sites More sharing options...

Good, remember to logout your apple account before changing SMBIOS, including iCloud, App Store, iMessage, Facetime, TV+ and anything else that is related to Apple. 2 Link to comment Share on other sites More sharing options...
