Time for a clean install

Since updating OS X from Mavericks to Yosemite, I’ve noticed that my laptop will randomly:

  • Not go to sleep when plugged into my Thunderbolt Display; the laptop display and Apple logo will remain illuminated.
  • Restart after a few minutes if a bunch of apps are open and my computer is locked.


I spent about two hours trying several of the suggestions in the support guide, “When your Mac doesn’t sleep or wake“. After the point of trying to reset the SMC and NVRAM, I feel I’ve put off a clean install long enough.

I’ve backed up my SSH keys for work, ran Time Machine and SuperDuper, and gathered the following articles for reference saved in Simplenote (from newest to oldest):

I promise to track my progress carefully, because I’d love to share it with you after I get to the other side.

If you have any relevant suggestions or links regarding this process, please leave a comment. I can use all the help I can get. 🙂

  1. I would backup
    ~/Library/Application Support
    and maybe even
    ~/Library/Saved Application State

    I also always taken screenshots of my Applications directory, screenshots of any browser extensions I use.

  2. I am kind of OCD and a neat freak so I only copy the files that I really need. Most of the code I write is version controlled on GitHub so I just clone those again once I complete my E&I (Erase and Install).

    The other trick that I use, which I did not mention in my CodeHive post, is that I save all my SSH keys in a folder on my Dropbox account. I then symbolic link that folder as my ~/.ssh folder. This way I don’t have to worry about losing my SSH keys during a E&I
