I recently started having issues that I was even unable to use Microsoft Excel as it would keep on hanging something I never faced prior to installing OSX Yosemite so I decided to reinstall OSX. I thought I would try to share my experience so other who might want to do the same. The process is quite easy.

  1. First of all copy all your data to external hard drive so that you have a backup to restore from
  2. Once you have backed up, choose Apple Menu and click Restart. While your computer restarts press Command (⌘) and R keys and hold it like that.
  3. Select “Disk Utility” and then click Continue.
  4. Select your start up disk from the list on the left, and the click the Erase tab.
  5. From the Format pop-up menu, select Mac OS Extended (Journaled), type a name for your disk and then click Erase.
  6. After the disk has erased, choose Disk Utility and click Quit Disk Utility.
  7. Make sure you are connected to Wifi.
  8. Select Reinstall Mac OS X, click Continue for further instructions.
  9. Select your start up disk which you just formatted in Step # 5.
  10. After a few clicks, the Mac OS X will start to download. Once it has downloaded it will install and you are all done.
