This script:
- Checks if SIP disabled
- Checks if FileVault disabled (will remove in the future if error 66 not caused by FileVault), this check can be skipped
- Disables library validation
- Adds -no_compat_check to the boot-args
- Automatically downloads and extracts patcher
- Runs installer with patcher, with a little bit different, but more stable method
