NOTE: Make sure your MacBook Pro has an Internet connection before proceeding. 1) Restart your Mac while holing down the LEFT Shift key until you see the Apple appear, then release. This will boot your Mac into Safe Mode. It may take up to 20 minutes to reach the desktop. Please be patient while various clean-up tasks are running. After you see the desktop restart you Mac normally. 2) Click on the Apple in the menu bar and select "Software Updates". Download and install ALL updates. Run this twice. 3) Open Finder and go to Applications>Utilities>Disk Utility and Run Disk Utility. Locate your internal hard drive (Macintosh HD) and highlight. Make sure you’re in the First Aid tab then run Verify. If your disk is "OK", run Repair Disk Permissions. 4) If you have less than 10% free disk space, I would recommend that you delete or move some files off of your hard drive to free up as much space as possible. Afterwords, empty the Trash. 5) Clean up your desktop by organizing files and programs into folders and relocate them off of the desktop as much as possible.
