My macbook was running okay. it wasn't the fastest computer out there but it could do the job. I use Photoshop and was using photoshop on my macbook. last week we had the power go out on us, at the time i was working on a project on my macbook (which had 0% battery life and was plugged into the charger). the macbook went dead. when i turned it back on, it was running slow as heck! ive tried "fixing permission" "purging" "verifying disk permissions" and i also found an article where people had luck by doing the following : power off> hold shift+control+option+power button for 10 secs. no luck. my macbook is still running like its 100 years old. any suggestions?
