Every time I click on something the ball starts spinning. What do I need to do to stop it?
[doublepost=1459569239][/doublepost]I tried your suggestions and it is running much better.If you're on OS X 10.9 or higher, download SMART Utility here. This will verify the SMART data of the SSD. Anything other than passed means the SSD is faulty. For an older OS, download it here.
If that comes back clean, try to verify the volume in Disk Utility. If the volume is corrupted. please quote this and we will run through a repair within the recovery partition.
Updating the OS is always a good shout. Get onto the latest version of El Capitan (10.11.4) if you're not already. This can be downloaded/updated through the App Store, and clicking the 'Updates' tab.
You can try reset the PRAM. Turn off the Mac. As soon as you press the power button to turn it back on, press and hold the following keys: Cmd + Alt + P + R. Continue to hold these keys down until you hear the Apple boot chime 3 times, then let go.
If you have 2GB RAM that is your culprit. The GF has a 2010 MBA 13" 2GB and it beachballs all the time. Unfortunately RAM is not user serviceable on the Air, could be time for a new machine.
[doublepost=1459645495][/doublepost]I bought mine in November, 2010. I have the El Capitan installed. I guess I have too much on my computer. I need to uninstall some things.I have the 2GB 2010 13". I bought it last year with Yosemite on it, which ran not great. Installed El Capitan when it came out and that made things a bit better, but was still not satisfied. Installed Mavericks and everything runs great. No beachballs when doing normal things. Are you able to install Mavericks on the MBA? Otherwise El Capitan is your best option, some say it runs fine for them on a 2010 2GB.
