If you have Photoshop, GarageBand and ten Safari tabs open on your MacBook for example, the overall effect will be less than snappy. By only running apps you're actually using, everything should be more responsive. This is especially true of older Macs with fewer cores, slower processors and graphics cards and less memory. The good news is that if you follow some or all of these tips, your older Mac could have a long life still ahead of it.
