[Keallei]

I'm glad you did a tutorial. I'm thinking I should start doing iOS tutorials

Good job!!!! Wewt to you!!!

[graciem616]

I just did and it only has Microsoft as an option....?? I'm soo confused.!

[graciem616]

I just purchased a used iMac and it's been switched to Microsoft Word and they guy who sold it to me doesn't remember his password. we've tried guessing but haven't gotten it right. If you can PLEASE help me switch it from Microsoft back to Mac & more importantly GET IN, that would be greatly appreciated!! PLEASEEE!!!!! & THANK YOU! (:

@graciem616 have you tried holding the option key when turning on the computer and selecting Macintosh HD?

[hleepymanzilla]

Umm when I did this, it had the apple symbol, the error symbol (A circle with a line across it) and a file with a question mark on it...HELP!

[GadgetHacker]

@hleepymanzilla your computer filesystem in corrupt, you will have to format. Resetting the PRAM and NVRAM has nothing to do with this, it is just coincidental that it finally found out you had some corrupt files that weren't addressed before.

Hi! On my MacBook pro it has an open firmware password on it and even resetting the pram will not be recognized along with all he other startup commands:( Is there a solution that comes up in your mind?

[alibrovidz]

@mortimormouse change the amount of ram in the computer then do it.
