Works perfectly on open core 0.6.1

NOTE: My default SMBIOS is iMac14,2. Seems like Apple is not going to support Big Sur on Imac14 models.

For this installation, I used iMac15,1 and even iMac17,1. It is not the best practises. Interestingly, it does work on using these SMBIOS. System is very stable. Have had no crashes so far.

Mikorist,

Did you try Big Sur in your Lenovo G5070?

Thanks
not yet ... I'm usually waiting for the final version for the laptop.

I finally got around to switching from Clover to OC 0.6.1 on my Catalina drive. Tried to install the Big Sur Beta to a new NVMe but after a few aborted installs, I remembered that the Beta won't convert MacOS Extended drives to APFS so had to reformat the new drive I was installing to manually to get it to work. All good now and it even sleeps... Although waking is another issue altogether as all I get on wake is two black screens.
Formatting to what?

Fresh Install on ASUS Z370 MAXIMUS X HERO at work and update ASUS PRIME Z270-P at home from 10.15.6 without any problem. My hackin0shs are working perfect. THANKS TO TONYMACX86 and other guys that shares their hard works.
Hello mohsenmehrvarz

Would you be so kind to share your EFI for ASUS PRIME Z270-P so that I can get OC setup on my PC.

Thank you .

An update to Clover (5123) has been released and supports Big Sur. Curious to see if it will work. Tony, any chance you will update the Cover part in the 11.0 installation thread?
