I’m running into a problem. After installing everything and restoring I get the infamous “Mach Reboot” and not to mention the preboot from preboot and FileVault. What Can I do to fix these errors and to at least successfully boot?

What do you mean by "After installing everything and restoring"??

Has anyone had any luck getting the 1220A audio to work without VoodooHDA?

Did you follow my VoodooHDA audio instructions?

It goes through the entire installation process successfully. Then I’m given the option to setup as new or restore from a time machine backup, I select from backup. Goes through restoring my apps, files, etc... then it reboots and instead of booting into macOS High Sierra it fails and I get the MACH reboot error.

I never tried to restore data from a backup during a clean install... Why don't you directly perform a macOS update on a clone of your previous system disk? In this case, you do not have to restore anything...

I did and ended up with the exact same problem with the clone install. So, I chose to try again using your guide with a clean install (then restored). Could it be it’s because of a bios setting or some kext that maybe stored in the library/extensions folder?

I can’t figure it out the “MACH reboot” error? How Can I get through

I’m going to try one more install. This time I am staying away from restoring. Wish me luck
