macos27.0.1 / keyboard A1243 problem
Macbook m4 Max with macos 27.0.1 and a1243 keyboard, do not work perfectly, all buttons on the space bar line and the letter A, do not work.
All this happened suddenly, at any moment, crazy!
This seems like a hardware issue.
Try running the Apple Diagnostics to confirm. If you are running macOS 26+, then first run the MRI followed by the Keyboard test. If the MRI reports a problem, or the keyboard test fails, then you have confirmed a hardware issue that will need to be repaired by Apple or an Apple Authorized Service Provider.
Note: If neither Command key works, then you may need to use an external keyboard to access the Apple Diagnostics. If using a Windows keyboard, then the Command key would be comparable to the Windows key.
