Does not work on a MacBook.

I tried to boot my operating system on a macbook and it hangs at Starting ACPI. I used a disk AND a USB drive and neither work, and now I can't use a disk. I want to test out my OS on bare metal, but this is the only bare metal I have, apart from a computer that ONLY supports UEFI, no CSM.

Does the default Cosmos kernel work there?

Not sure, although I find it unlikely considering the nature of the issue.

Use CSMWrap on that UEFI only machine. https://GitHub.com/FlyGoat/CSMWrap

I'll try that.
It's a chromebook that I installed a UEFI firmware for, which is why I was hesitant to try that.

Sorry, didn't check my github, things happening in life.

Also, I know it's bad practice to write messages back to back, but I also tried an older mac, an iMac11,2. 21.5' iMac from 2010, however that ALSO didn't work.
