Sometimes Apple gets a little too cute. Exhibit A: you can resize a window from any edge, but where are you supposed to grab? In an effort to strip away clutter Apple also stripped away the sides and bottom of the windows. Here’s a better way to resize things: Moom. See it in action by clicking this link and then get the free download. Yes, you will have to take a couple of minutes learning how Moom works, but it’s completely worth it. I use Moom on my Macs and recommend it without reservation.
If you want to buy Moom click here to get it straight from the Mac App Store.
