Reinstall OSX or Erase and Install?
Hi all, recently my iMac has begun to slow down significantly (this wasn't as a result of an update to Mavericks), so I have backed everything up and I am planning on 'starting over'. With the recovery tools of Mavericks, I have two main options: Firstly, I can 'reinstall' OS X, which, 'Use the built-in recovery disk to reinstall OS X while keeping your files and user settings intact'. Alternatively, I can, 'erase and reinstall' OS X, which just wipes the hard drive and installs a squeaky-clean new Mavericks. Since my Mac is a little clogged up with files, and I assume its depleting speed is a result of a handful of applications or the likes that I've installed, the, 'Erase and install' option seems like the best bet for me. Before I go ahead with this though, I was just wondering:
- For what reason would you just reinstal lthe OS? Would this only be if your OS is playing up, or does it refresh certain other files as well?
- What steps will I need to go through to set the OS/users up again? Do I need iCloud accounts or whatnot?
- Is there anything else I need to know before I've gone ahead with the erase and reinstall?
OS X Mavericks (10.9)
