Optimizing OS X Yosemite

Periodic Maintenance Required:

To maintain the highest level of performance and security you must periodically do a few tasks manually:

  • Turn off the Finder application every time you open or reboot.
  • Close applications other than your player or primary software.
  • Clone or backup your media and documents as they change.
  • Repair disk permissions every time you rip or download files.
  • Update software only as needed – if its not broke, don’t fix it.
  • Always clone or backup your boot drive before updating.
  • Repair disk permissions after updating or installing Apps.

  1. Hey Ben,

    This is a pretty radical set of recommendations. I’m a Mac computer consultant for a living, so am familiar with most everything you describe here, but I think you could do a better job of explaining why users should do the individual steps. In particular, the suggestion to turn off system sleep should be accompanied by a description of how a user should do to avoid screen burn-in. I know it’s much less likely than it used to be, but it can still happen, depending on the display setup they are using. I’m also very curious as to what the benefit is of turning off journalling on all hard drives.

    I would imagine you often get questions as to the ‘why’ of many of your suggestions, so it would be great if those answers were included in your post as well.

    Keep up the good work!

    Sincerely,
    John

    • Hi John,

      Thank you for your supportive comments.

      Please keep in mind that most of our customer are operating a music/media servers. For those listening to music only they mostly operate their system “headless” without monitor, keyboard, or mouse, and view/control using an App on a pad or phone. Those that are using their HDTV as the monitor simply turn off their TV when it is not in use.

      In any event, your recommendation to add a paragraph on managing screen burn in is a good one. I’ll make a note of that and try to add some info on that with the next set of edits to the blog. BTW, what would you recommend as a good strategy to manage screen burn in?

      As for the “Journalling,” that too is more targeted to the AV user as opposed to the office user. It does save a bit of system resources and speeds things up slightly, but it is more significant in AV server applications.

      All the best,

      Benjamin

  2. Can’t thank you enough for this optimization guide. I am new to the Mac world, but following your very detailed and easy to follow instructions, I created a bootable SD Card, installed a fresh copy of Yosemite and optimized my late 2012 Mac Mini to use as a music server.
    Since I boot from the SD Card, one other thing I do is after every reboot I go to Disk Utilities, right click on my internal HDD and click unmount. No need for the disk to spin and possibly add noise.
    Excellent post!

    • I personally don’t like either one: too bloated with all sorts of unnecessary features. I prefer simpler versions of OS X like Snow Leopard.

      In their infinite marketing wisdom Apple makes their computers only forward compatible. This means you can’t load a version of OS X that is older than the one your Mac came with.

      My favorite Mac Mini for Audio is the best of 2012 with the i7 dual-core CPU and video co-possessor. Even though Apple claimed it could only recognize 8GB of RAM the i7 version can use 16GB of RAM. This 2012 Mac Mini runs on Snow Leopard through Yosemite.

      The question becomes more of what age Mac Mini you may have and then which version of OS X that your specific Mac Mini runs on. Then it becomes a question of which OS X you can run performs best with your favorite player software and/or DAC drivers. With some combos Yosemite will perform better and with some Mavericks will perform better. Some combos won’t work at all.

      Since player software companies and DAC manufacturers usually optimize for the newer versions of OS X there is always a zone of years of OS X that work with most players and DACs. Eventually older versions of OS X become no longer compatible with new players and USB drivers.

      Of course that’s why my company will soon be offering an optimized/minimized Linux option with JRiver that will be more stable and perform better than any OS X or Windows.

      I’m tired of all the buggy operating systems from Apple and Microsoft. I swear Apple must have hired the same clowns that engineered Windows Vista to create Yosemite : P
