Is it possible to downgrade my MacBook Pro that is running OS X Mountain Lion back to OS X Lion? If there is, can anyone tell me the easiest way? Thanks.
 
A clean install with the Lion installer should do it.

If you're running Mountain Lion, that means you're a developer, since it's not commercially available yet. If you're a developer, you should be able to figure the answer out on your own. If you're not a developer, speak to the person who gave you Mountain Lion to get their help. That would be a lot faster, methinx.
 
And people wonder why Apple users can be so polarizing.

That some here choose to treat their fellow enthusiasts with such judgmental, condescending criticism is more a reflection of their own insecurities.

In fact it makes the OP's honest question, look just that much more dignified.

Speaking of condescending...

No, it doesn't. It's a question that has been asked over and over in countless forums. Also, a developer should now how to do this, as the release notes mention this.
 
So instead of helping him you have a little mini argument instead. Great support, guys. Very MacRumor-like.
 
Reinstall from the Lion disk (if you made one). If not, use the Install disk that came with your Mac.

When the Installer opens, go to Utilities > Disk Utility and wipe your disk to Mac OS X Extended (Journaled). Then install as planned.

totally agree, not sure why the downvotes, must be sensitive people who dont like the blunt truth.

to the OP if you can indeed develop software you really should know how to downgrade your OSX version
