I just picked up a Magic Trackpad to change things up a little bit. I’d been using a Logitech Revolution MX (one of the best mice ever) for almost four years (!!) and I decided I wanted to give trackpads a try. Much to my chagrin, the trackpad was a mess, skipping, skittering, and jumping across the screen when connected to my Bluetooth dongle, a bog standard iOGear model I purchased years ago. I thought it was a software update, but it wasn’t.

It seems that when the Bluetooth module is connected to an underpowered port it’s not fast enough for mouse work. The result are skips, jumps, and poor tracking. I moved it to a USB port right on the Mac Pro and instantly the problem was solved. Who knew?
