Performance Tweaks/Tools for MacOS (Macbook Pro) I am using a Mid2010 Macbook Pro (2.5 GHz i5, 8GB RAM, regular HD (no SSD) and still on MacOS 10.9).

I am fully aware of the fact that, as the computer gets older, it may get a little slower due to more space used on the HD, more applications installed etc. etc. However, I feel that in the last few months I feel like the performance has degraded more than it should be. What do I mean by that? Well, it takes longer and longer for me to boot the Mac, applications take longer to start and it happens more and more often that they simple freeze for a short moment. Lately, I even had to use a cold reboot by pressing the on/off button long because the whole system froze when I was simply watching some videos.

Now, I am looking in how to get a little bit of the performance back, i.e., either some tips that I can directly use in the OS or some tools which help me. Unforunately, googleing them brought up a whole bunch of differerent tools, not all of them looking extremely reliable. I'd be grateful if some of you have a couple of tips for me.

Thanks
Onyx is a great app to help you clear out a lot of the clutter you may have accumulated over the years and speed you up a bit. Be careful though, it's a powerful tool so make sure you know what you're doing with it before you do anything.

As for boot time, make sure you don't have a lot of daemons loading at launch. One easy way to check is to go to System Preferences > Users &amp; Groups > [Your User] > Login Items and remove anything listed there that you don't need launching at startup. Anything with a default document icon means it doesn't exist and can be safely removed. Ideally, the only item that should be listed is iTunesHelper, but if you don't use any iOS devices, then you can remove that too.

Another few places to check for daemons and login items is "~/Library/LaunchDaemons/", "~/Library/LaunchAgents", "/Library/LaunchDaemons" and "/Library/LaunchAgents". If you see anything listed for software you don't use anymore, trash it. Certain other apps load daemons in to here too that you might not need; Adobe is a big culprit here with their Flash Player updater, Adobe Reader updater, and AAM. If you're unsure, leave it where it is.
