Mac Pro 2008 Startup Manager
Ultimaker cura mac. Given you're already following the Startup Manager instructions from Apple and having tried the other ⌥ alt/option key as your keyboard has that key, then maybe also try the SMC and NVRAM resets, and try an external keyboard? Run the resets, and remove all external USB devices except for an added USB wired keyboard, and try the ⌥ alt/option key there on the off chance this is some odd keyboard mapping issue with the firmware. If that fails, you're probably headed for a visit with the local Apple Store or with your local preferred hardware repair provider.
