Why is my Mac Running Slow?

When your Mac starts up, programs you use frequently can be set to automatically launch at startup: Safari, Mail, Dropbox, etc. And some programs may have configured themselves to launch at startup whether you want them or not — Skype, anyone? You may have extraneous items or out-of-date tasks vying for attention. Some of these items may no longer be needed or current.

For example, if you used to run Symantec AntiVirus on your iMac in and have just migrated things along ever since, there may be one or two Symantec programs still set to launch at startup.

If you need to force quit, restart the computer afterward. Speaking of restarting — why do techs always tell you to do this? But more seriously, after your computer has been running for a while and swapping lots of things in and out of RAM, or after a program has crashed, small errors can snowball into bigger glitches.

The RAM storage itself can get fragmented, or stalled background processes can begin to interfere with running tasks. Rebooting the computer clears out everything from RAM, stops all running processes, reloads the OS and brings things back to square one. Modern operating systems such as OS X, Windows 7 and Linux are much more resilient than in days of old, but the need to reboot has not gone away entirely.
