MacPro5.1 + OpenCore bootpicker gone, no Apple logo at startup

[RolfNoot]

Hi all,

I updated my MacPro5.1 with a OWC Accelsior 1M2 PCIe to NVMe.

After installing the screen froze while accessing the SSD.

Now after startup I don’t have Bluetooth anymore, bootpicker has gone (even holding down the Option key doesn’t work.). Apple logo has gone at startup til the point where the background becomes white and the logo black.

I tried using the old HD but no Bluetooth as well and also no logo, no bootpicker (using Option) and no Bluetooth.

I’m using Monterey and the latest OpenCore.

I tried a Bluetooth USB stick as well but no help.

Any ideas?

Thanks,
Rolf

Update. Bootpicker & Apple logo fixed by putting the switch on the HD7950 graphics card in the other position. I might have accidentally flipped it while reinstalling the card.

Now only Bluetooth remains an issue.

Bluetooth solved by using an old HD with High Sierra. The bluetooth module was stuck in firmware update mode and didn't work with OpenCore. Using high Sierra solved the issue.

Thanks.
