What does this combo do: CMD and Power Button?

What happens when you hit CMD + Power Button combo?


I was reading various suggestions on this forum for getting a new wireless keyboard going when you cannot type in the password to log in. After trying this combo I have not been able to boot up the computer. It hangs up halfway through the gray screen with Apple icon.

Mac Pro, OS X 10.10

hi, ooTRIPLE0o

yes, bluetooth keyboards tend to be troublesome and problematic on initial startup/or for troubleshooting

my suggestion to you is to get a wired USB keyboard and mouse to use as a spare in that case. Pretty much any USB wired mouse and keyboard set will work on a Mac
