MacOSXpert
A person who knows the Mac OS X inside and out and can curse at it when it crashes.
My MacOSXpert turned my laptop into a toaster just by opening 17 tabs.
He called the Mac OS X a 'piece of trash' after it froze on him during a Zoom call.
My MacOSXpert said the Mac OS X was 'too slow for a turtle' and then rebooted it 10 times.
