#Dual_boot worked fine on an old Macbook Air, but on my Intel Mac Pro #Ubuntustudio will not install. The USB drive with the Ubuntu iso does show up, but when selected there's a popup saying: 'The version of macOS on the selected disk needs to be reinstalled. Use Recovery to reinstall macOS or select another startup disk.' Whatever I do, I can't install it. Is the hardware preventing the install, or macOS Tahoe maybe? Any ideas anyone?
- INTEL Mac Pro
- macOS Tahoe 26.2
