Hello, and welcome to JustAnswer.com!My name is XXXXX XXXXX I'm here to help.
Try starting your Mac holding down the Shift key on your keyboard. Hold it until you see the Apple logo appear on the screen, and a progress bar underneath it. If that doesn't start it up, let me know.
My MacBook starts up ok after I log in and things start to boot up seconds later the screen is wiped with an instruction to restart my computer.
Even after holding down the Shift key?
Ok. so far so good safe boot seems to have worked... I've lost my screen saver which is a sign we are getting somewhere... now what
Sorry for the delay, I'm here.
So you recently installed MacKeeper?
Inadvertently yes. I have now removed it, installer and program from my applications and am useing easy finder to locate the files.
Okay, so you just did that, or you did that and then the problems started?
No the problem has been solved in that I can now run my computer. I am proceeding with trying to remove all the related files. Is that what I should do, and how will I know if I have been successful?
No, that's great, you're doing just what you should. You're currently running in "Safe Mode", that's what holding down shift did. Once you've removed those files, you'll want to restart the computer again, without holding anything down.
Ok thanks, XXXXX XXXXX I can do this ...
No problem, let me know what happens when you restart.
Any luck yet?
Everything is back to normal. Thanks for your help,
