So Mountain Lion has been released and with it has been some issues. One is the overheating issue that I will be discussing shortly but, probably the most important of all is that Mountain Lion by default restricts you from installing and using any software not approved by Apple through their app store. Apparently Apple are charging $99 for developers to become approved and is another cash cow that will help them to keep everything under their umbrella.

There are a ton of awesome new features in OS X Mountain Lion, one of which is called Gatekeeper. Gatekeeper is designed keep bad software off your Mac (malware, viruses, intrusive apps etc). In 90% of the cases that is super helpful BUT what if you want to install something from the Internet that doesn’t have Apple’s app store’s seal of approval? LIke, in my instance the  free and awesome video conversion software MPEG Streamclip?

You will know when you need to do this guide when you try to install or run an app from the Internet and this comes up:

If, like me you use a lot of non approved software you will want to know how to fix and resolve this issue as getting this all the time is counter-productive to your workflow. Here is how to bypass these errors.

1. Apple Menu
2. System Preferences
3. Click on Security and Privacy
4. Click on the lock in the bottom left hand corner (if it appears to be locked). Then enter your administrator password
5. Once the Window is no longer grayed out, Click the GENERAL tab.
6. Click the radio button next to “Anywhere”
7. It will bring up a pop-over box asking if you are sure, click “Allow from Anywhere” and you’re done.

In the coming months and years most of these developers will get their digital approval and this will no longer be needed but, for now this proved VERY useful to me so I wanted to share it with anyone and everyone that is looking to use no signed software with OSX Mountain Lion.
