If you’re getting that wretched beach ball it means your Mac is struggling – and you’re getting it while doing something as intensive as just opening a folder – then do this:
1) Quit your browser
Especially if you’re not actually using it. And especially, most especially, three times most especially if you the sort to leave a lot of windows and tabs open. Each one is taking up some effort from your Mac as it tries to keep each one updated all the time.
For your own sanity, get into the habit of closing a tab when you’re done with it. Bookmark it if you’re going to come back to it later, but close it now.
In the meantime, though, quitting the browser is a one-click device for speeding up your Mac.
2) Delete things and then empty the trash
I believe the general consensus is that you need to keep about 10% of your hard disk space clear in order for your Mac to work away merrily. (Because it uses some space as it’s going.) If you can possibly do it, go for a third instead.
It makes the most enormous difference, says William who this morning found he had 200Mb of space left on his MacBook Pro’s 250Gb drive. Which Wolfam Alpha tells me is 0.08%.
Yep, I beach balled a lot this morning.
