Hi Chris,
I have been successful in installing Big Sur using the newest Creator tool: https://github.com/chris1111/HP-Probook-EliteBook-Package-Creator-OC/releases/tag/V1 . However, I do not have sound ,Brightness Control, Battery display.
Any idea how to fix it ?
I am really appreciating your work. It really helps the installing process less painful.
Its clearely DSDT creating problem, what is the exact model of your CPU because somes 6470b works on the HD 3000
Post edit
CPU: Intel i5-3320M @2.6ghz
Delete EFI from SSD then Reboot from USB and retry, I hope you have an SSD, not a old mechanical toshiba HD
after that post here the EFI folder on ZIP file
I have disabled bluetooth and wifi kexts. It works very well now . Thanks !
