Hi @laisangbum ,

• Which laptop are you using?
• What BIOS version are you having?
• Are you trying to boot 11.0.1 or 11.1 Big Sur? If you installed 11.1 BigSur then you should try the release I just released v9.0 with OC 0.6.4
• Also make sure that you clear the NVRAM (press space in the OC picker and select clear NVRAM)

Best regards!

i use xiaomi air 13.3 2016

• Bios version A07
• i install mac 10.15.3 macOS Catalina

Try installing 10.15.7 or 11.1. Why don't you try Big Sur ? I think it is more likely the version of the OS (10.15.3)

make sure also you have followed this https://github.com/sakoula/XiaoMi-Air-6200U#unlock-cfg-lock

I can not download Big Sur. after install 10.15.3 i boot to Mac for the first time, the system show 10.15.7.
the first time i didn't unlock cfg, the system cannot boot to install screen. after clear nvram and unlock cfg, it could boot to install screen.

I can install Big Sur, but after reboot, it show ocb startimage failed - aborted. I can use it normal until reboot.

try to reset nvram and make sure your EFI is the latest release.

Hi Everyone!

I am facing on the same problem.

I have installed mac Ventura 13.3.1.
I can see the system is installed successfully. but after restarting, I can not boot to the system.

It gives an error.

Is there any help?

Thanks

Hi @whtiehack
Thanks for your help

How can I boot to install big sur? I can not boot with even USB. It always gives OCB: StartImage Failed - Aborted or Already Started

Please help me.

hi there, I do not think that Ventura is supported for skylake processors including the xiaomi. So in any case it would be better to install monterey in the specific laptop. Unfortunately I have not done it and I do not have access to the laptop all the time any more.

The ocb startimage failed - aborted can be caused by either an old version of OpenCore trying to boot a new version of macos or something related to filevault.

So:

• Are you trying to use an separate disk for installing macos?
• Have you unlocked your CFG? (what version of bios are you using?)
• Are you using XiaoMi-Air-6200U right?
• Which version of OpenCore are you using? Is the one from the repository?
• I will try to update the EFI for installing and booting Monterey this weekend.
