Many Mountain Lion apps will function normally under Mountain Lion, but many won’t. Of particuar concern are the various utilities that help keep Mac systems secure, scan for viruses and malware, integrate with enterprise systems in businesses and schools, and dianose and repair problems.

These tools often require much deeper integration with OS X than other apps. That means that developers need to ensure they function as intended and don’t damage any documents, files, OS X system components, or other apps. That can sometimes delay releases of key utilities.

Here’s a list of Mac utilities and enterprise tools that have confirmed Mountain Lion Compatibility

Despite releasing OS X Mountain Lion and a whole host of app compatibility updates this morning, Apple has finished delivering new software. The Cupertino company just rolled out iTunes U version 1.2, which adds note-taking, and new search and sharing features.

With every new major release of OS X, there are, unfortunately, a lot of people who end up having problems. The big news this morning is that many new Mac owners who are eligible for a free Mountain Lion update can’t redeem their codes for the update, but these poor sods aren’t likely to be the only ones with problems, as millions of Macs across the world do their darnedest to trip up the attack of Apple’s latest cat.

Apple’s latest jungle cat is called Mountain Lion, and the new version of OS X is available as a $20 purchase in the Mac App Store. If you’ve updated to a new version of OS X before, you know that getting everything in order isn’t always as easy as Apple makes it out to be. In this how-to guide, Cult of Mac will show you how to get your Mac ready to install OS X Mountain Lion the right way.

Following the release of OS X Mountain Lion this morning, it seems Apple is also pushing out updates to its applications to ensure they’re compatible, and to take advantage of new features. One of the apps on that list is iPhoto, which now has new sharing options in version 9.3.2.

It took a good half hour, but Apple has now activated OS X Mountain Lion’s free up-to-date program following this morning’s release, allowing users with a qualifying Mac to get their hands on the latest release without paying a penny. All you need to qualify is a new Mac purchased after June 11, 2012.

LiveClock, a tweak from Ryan Petrich that animates the Clock app’s icon to show the time, was once one of the first tweaks I would install after jailbreaking my iPhone. But after installing iOS 5, I had to live without it — because it just wasn’t compatible. Now, nine months after iOS 5 made its debut, it is!

Fantastical is one of our favorite Mac apps here at Cult of Mac, because it makes managing your calendar a breeze — unlike Apple’s built-in Calendar application. Today it got a massive update that introduces support for OS X Mountain Lion (coming today!), Retina graphics for the new MacBook Pro, and more. It also has 50% off its price tag for a limited time.

Temple Run is an original, popular, and successful game by Imangi Studios. It was picked up by Disney to become Temple Run: Brave, a tie-in to the Pixar/Disney flick of the same name. If you haven’t already downloaded it, do so now. We’ll wait.

Pyramid Run is a horrible rip off of Temple Run. Do not download it. I’m not even going to link to it, but the similarities are clear. It’s not even a careful attempt to re-skin or remix the original. It’s a blatant cash grab, as you can see when you read the predominance of one-star reviews.
