A1481 Late 2013 Mac Pro (Trash Can) Clean Bios needed

[Stephen]

Can't seem to find it on here so sending a request. Did a search and nothing came up. We ordered 3 Bios chips for these Mac Pros (they have been installed with Monterey and we suspect it corrupted them firmware on the Machines) so we need to replace the bios with an older clean version to wipe it and update to Mojave.

These are not EFI locked. I believe the firmware is corrupted and needs to be cleaned up.

Solved the issue however we should get a Bios for future Mac Pros that have EFI locks on them.
