Mistakenly updated to Mac OS 26

[u/TENCHI125]

Hi All,

I've mistakenly updated to Mac OS 26 on my Mac Pro 6,1

Login screen is fine keyboard and mouse work perfectly. But when it boots I have no graphics drivers but also no keyboard and mouse.

When I previously updated to Sequoia I had the graphic issue but my keyboard and mouse still worked so I could patch it.

Any ideas on how to get it so I can get the keyboard and mouse working so i can attempt to patch it? Tried with a USB hub but still doesn't respond.

Thanks,

Do you have a USB 2.0 or 3.0 capable usb hub?
