How to Install Applications From Any Source on Your Mac

1The newer versions of Apple’s OS X operating system have a feature built in that helps users avoid installing software that can harm or damage their system. Called Gatekeeper, this setting on your Mac will stop any software that wasn’t downloaded from the Mac App Store from installing.
While Apple’s intentions were good, this feature can really get in the way of installing software that comes from any source that isn’t the official App Store.
It’s easy to turn this setting off so you can once again install whatever software you choose, and to use software like Scrubly, it’s not just a good idea to turn Gatekeeper off, it’s necessary!
Follow the steps below to turn Gatekeeper off and regain your freedom to install whatever you want. It’s possible to turn it off on a per-software basis, but as long as you’re even moderately familiar with your Mac, this setting will just get in the way. Turn it off now and save yourself the headaches later.
