## What this SSDT does
|
|
|
|
So on 400 series motherboards, certain OEMs have broken the ACPI spec and this results in issues when booting into macOS. To fix this, we have a few ways to fix it:
|
|
|
|
* Turn off the RHUB and force macOS to rebuild the port
|
|
* Quick and dirty, not recommended long term
|
|
* Fix the bad ACPI table
|
|
* Proper fix
|
|
|
|
Ideally, we'd want to always go #2 but we'll still go over how to to do both methods.
|
|
|
|
The following platforms will require fixing:
|
|
|
|
* Mobile Icelake(currently Dell and Lenovo are the 2 known with this issue)
|
|
* Asus Z490 (Gigabyte and AsRock users are fine, whether MSI currently this is unknown)
|
|
|
|
