I installed the keyboard firmware update on my MacBook Pro last night and it fixed the annoying keyboard problem I’ve been having since I got this machine.
I didn’t even have to reboot when I ran the updater; it simply required quitting all open applications. It took about 20 seconds to run and the keyboard was fixed. The console log showed a series of messages from HIDFirmwareUpdaterTool ending with “Flash image verification succeeded” and “bootload success”.
good thing this got fixed!
