Let out a little roar, Mountain Lion Mac OS X is finally here!

Apple’s new desktop operating system, Mac OS X Mountain Lion, is available today, Wednesday 25th July.

Over 200 new features will be coming to Mac OS X with Mountain Lion, including deep Facebook and Twitter integration, Game Center features and AirPlay screen mirroring.

When it lands in the US, it’ll cost $19.99, with UK users paying a measly £13.99 for the upgrade.

Mountain Lion will not be available in an physical media formats however, so brace yourself for a sizeable 4GB download.

Those who have bought a compatible Mac product from Apple or an Apple Authorized Reseller on or after June 11, 2012 will also be eligible for a free upgrade through the OS X Mountain Lion Up-to-Date Program. Click here to check if you can grab it for free.

However, if you’re working away with a Mac that uses a 32-bit kernel extension (KEXTs), it looks like you’re out of luck. Mountain Lion requires your system be running the 64-bit Kernal we’re afraid. If you’ve got an iMac or MacBook built after 2007, you should still be fine.

We’ll have a full Mountain Lion review in the coming days, so keep your eyes peeled for it.
