Have you noticed that your Mac isn’t performing as well as it did when your first took that thing out of the package? You’ve treated it nicely its whole life and this is how it thanks you — freezing upon the most simple of tasks like opening a browser window or basic application. Turns out there are some simple solutions which have been proven to help Macs speed up and return them to their former glory.
Repair Disk Permissions
The first and easiest way to attempt to speed up your system is by allowing your computer to check the disk permissions for every single file, folder, and application on your computer and repair ones that have been corrupted. These permissions often get muddled when users install new applications which have their own set of permissions which can overlap and confuse the machine, slowing it down. Simply open Disk Utility and select the hard drive partition you’d like to repair and click the “Repair Disk Permissions” This process has never taken longer than half an hour and has always worked to speed up our computer in the end. A third-party program we can recommend and is highly praised by the tech world is Onyx. This free application is a basic system maintenance manger which can help tidy up the loose ends around your machine helping it get into tip-top shape.
Check for Memory Hogging Activity
A slowing computer could be the victim of processes (either malicious or harmless in nature) which have been eating up a lot of precious memory resources. When someone’s computer begins to slow down, many think to simply restart it. This isn’t exactly fixing the problem. It may give temporary relief since it wipes all of those running processes but they will likely just repair over the course of your session. So we need to purge them. Open Activity Monitor from your Utilities folder and take a look at all the processes running. List the view from Real Mem usage in ascending order so you can see the worst culprits at the top. If something is hogging a lot of your space and you dont know what it is, we recommend Google searching the name and seeing what comes up. You may be able to simply cancel it or find a way to wipe whatever was initializing that process from the beginning.
Buy More Memory
Sadly, there is one solution that does involve spending more money. If your Activity Monitor reveals that the processes running on your computer are all ones you need to work and you can’t sacrifice closing any of them, you will have to buy some more. As with everything else computer-related, cutting costs for hardware is a bad idea. Spend the money up front so you know you’re getting a quality product that wont simply not work or worse, do damage to your existing system. We recommend going directly through Apple for their authorized memory and their helpful site browsing tool so you don’t accidentally purchase the wrong kind.

You were spot-on with your suggestions for using Onyx, Activity Monitor, and upgrading the RAM, but I cringe every time I hear someone suggesting "repair disk permissions" in order to fix something that it /does not fix/. This whole cargo cult regarding it started back in the early days of Mac OS X when it was indeed capable of curing several common ailments that users were facing. Over time, it became a first step in pretty much every novice troubleshooting guide, despite the fact that it only actually cured one sort of problem. That said, it hasn't been a useful maintenance tool ever since 10.5 came out in 2007, since 10.5 changed the way that things work under the hood, and at least one Mac User Group I checked is actively discouraging its use for maintenance tasks. Even when it was useful in the pre-10.5 days, it never was really responsible for offering improved system performance.
Just to run through some gripes, permissions are referred to as "incorrect" rather than "corrupted" when they're not set as they should be, and your computer doesn't become "confused" or get slowed down by them, nor is there such a thing as "overlap" in the sense that you used it (they're simply changed). Instead, if your permissions are incorrectly set (which happens for the reasons that you correctly identified) to the point where they're impacting the operation of the computer, you'll see much more significant issues. For instance, applications may fail to launch, errors may appear during typical use, software may crash, or, in extreme cases, you may even have a kernel panic. Long story short, things break, rather than slow down.
If you just stop and think about it for a moment, the idea that your computer gets slowed down because of incorrect permissions makes no sense. For it to make sense, it would suggest that software which has been incorrectly forbidden from accessing a file is able to take an alternative, but longer, route to access that file. But if that were true, it would mean that the software was accessing a file it was forbidden from accessing! Talk about poor security!
So, to close all of that up, any perceived speed improvements you've seen were, regrettably, likely just you seeing what you wanted to see.
For some more information on repairing disk permissions from back in the days when it was actually useful:
http://support.apple.com/kb/HT2963?viewlocale=en_US
Also, I'd add that if users are on 10.6 or earlier, they should make a point of quitting applications when they're not using them in order to free up memory. Of note, not all applications quit when their last window is closed, so you should check your Dock to see if it is still running (running applications have a light under them). In 10.7, this is no longer a concern, since the OS will dynamically quit running applications that you're not using in order to reclaim memory when it needs it (10.7 automatically saves and remembers exactly how you had apps, so quitting them doesn't cost you anything).
In before 'buy a new mac' LOL.
@Aichon - thanks for your thorough response! Repair Disk Permissions was recommended in a Pogue book that I picked up when I purchased my MBP three years ago and I've used it several times. It always felt more like a wishful ritual than a necessary process. What's more, in three years of Mac use, I've never noticed the "lights" under the active apps in the docks - thank you for that tip!
i recommend buying more memory but don't go through apple unless you also feel like emptying your wallet.
There are a lot of great sources for quality RAM online and often their websites even have a tool to help you figure out what RAM you need.
Or just ask a friend, everyone should probably have at least one friend that knows something about it. I have upgraded all of them at work, my own imac, and also upgraded a friends macbook pro on the tailgate of my SUV. This is something you DON'T need to pay apple for. It is a user upgradeable part for a reason.
Another thing you could do is actually install a better hard drive. Especially if your mac is a few years old there are a lot better hard drives on the market now. I upgraded my old 250gb imac HD _circa April 2007) with a new 1tb model and not only did i get 4x the space but the new hard drive runs faster, quieter, and cooler. These process is obviously a bit harder, but worth it. With the white imacs it can be done in under 10 min.
+1 for @Aichon, every last word. Computers don't slow down because they get "confused" about permissions on a given file.
There are certain kinds of problems "repair permissions" might fix, but performance isn't one of them. It's a kind of magical thinking, not unlike "maybe if I get my car's tires rotated, my engine will be more responsive". It simply doesn't work like that.
More RAM usually helps the most. crucial.com offers name brand RAM upgrades for much less than Apple does; and they have guides to help ensure you buy the right stuff. I've been buying RAM from them for years; I recommend them.
Check Safari in Activity Monitor, that thing is a hog. I'm not sure if they fixed it in the version released last week but if that is eating over a Gig then switch to firefox or chrome. I find Chrome is the fastest.
Starting to think we need at +1 option for comments here...
Lame article.
Trolling for page views.
Instead of looking around for the little blue lights in the Dock to tell if you have a program open, may I recommend a keyboard shortcut? If you simply click "Command Tab" (hold your thumb down on Command, and hit and release Tab), your Mac will pop up the icons of every application that is currently running, as well as the finder icon. AND as the icing on the cake, if you hit "Tab" again (your thumb should still be holding down the Command key), you can switch between each of the applications open on your computer seamlessly and painlessly.
Seriously. It's how I know what's running, AND it makes life so much easier.
As an extra tip for the power users, you use "Command `" to switch between windows within a single application (i.e. if you have two different Safari browsers open, it will switch you between the two browsers). (Note: the ` is just to the left of the 1, and just above Tab).
If you're looking for quality RAM you can use crucial.com, they have a nice wizard to make sure you buy the proper RAM for your particular Mac. I literally upgraded my unibody MBP from 4GB to 8GB this morning with their RAM and a jeweler's screwdriver set. Works a charm!
Nice and informative comment!! I think we are missing one more points that can slow down you Mac and that is: Fragmentation of hard drive, Unwanted and large files, language binaries.
My Mac was running slow from some days back, one of my friend solved this issues very easily using the Speedup Mac software by Stellar.
