If you’re an IT guy or gal, there’s a good chance that you’ve got a couple of machines sitting underneath your desk. There’s also a good chance that those machines aren’t all running the same operating system. So what’s the best way to seamlessly switch between those machines using the same keyboard and mouse? A fancy (and expensive) KVM switch? Nope. Try the free, cross-platform app Synergy instead and you’ll be switching between machines with only the flick of a cursor in no time.
