    I've read a few articles online about repairing permission and how it can help my iMac perform better but I've seen warnings about doing this as well. Has anyone done this? Is it safe? I'm recently had a few crashes and was wondering if this would help.

    Some people repair, or recommend repairing permissions for situations where it isn't appropriate. Repairing permissions only addresses very specific issues. It is not a "cure all" or a general performance enhancer, and doesn't need to be done on a regular basis. It also doesn't address permissions problems with your files or 3rd party apps.

    There are times when repairing permissions is appropriate. To do so, here are the instructions:
    If repairing permissions results in error messages, some of these messages can be ignored and should be no cause for concern.

    It sometimes fixes things, but it rarely improves performance. Instead of using Onyx, use Disk Utility. Onyx can be a bit buggy and dangerous.

    Thanks. I'll probably leave it alone for now, but if it gets any worse, I'll take a shot.

    If what gets any worse? Repairing permissions has nothing to do with performance. If your Mac is running slow, it's likely one of two things- you need more RAM or you have a process eating CPU cycles. Launch Activity Monitor and see what's using your CPU and check your RAM.

    It's not really a performance issue and as far as I know, my RAM is fine. Just trying to figure out what causes two recent crashes and why when running any program my memory goes way down. I've got 12 GB but when running Photoshop or Lightroom, it goes all the way down to under a gig. Just trying to figure out why or see if that is normal.

    You don't need to worry about your free memory available, as inactive memory is also available to apps as they need it. You only need to track page outs. Launch Activity Monitor and click the System Memory tab at the bottom to check your page outs. Page outs are cumulative since your last restart, so the best way to check is to restart your computer and track page outs under your normal workload (the apps, browser pages and documents you normally would have open). If your page outs are significant (say 1GB or more) under normal use, you may benefit from more RAM. If your page outs are zero or very low during normal use, you probably won't see any performance improvement from adding RAM.

    Page outs are zero. I guess it is working like it should. Thanks.
