The best Mac app is now available from the Mac App Store. Now you can download CleanMyMac X directly from the Mac App Store but some features are missing because they aren't allowed by Apple. In spite of the rather unfortunate news about the misbehavior of App Store apps and the delays of up to nine months prior to Apple removing them, obtaining software through the Mac App Store is still probably somewhat safer than doing a Google search for an app and clicking on whatever you happen to see in the results. Lyn is a fast, lightweight image browser and viewer designed for photographers, graphic artists, and Web designers. Featuring an extremely versatile and aesthetically pleasing interface, it delivers an easy-to-use geotagging technology and a complete solution for sharing your photographs. What we can say with certainty is that Lion is the most relevant Mac OS X release in years. If you have $29 to spare, you can grab Lion from the Mac App Store today, after making sure you’re running Mac OS X 10.6.8, which you’re able to download from Software update.
Some users have reported an issue where the Mac App Store will no longer update their apps. Although the update information for the app shows in the App Store, when the update button is clicked, the app does not get updated and the app update still shows in the App Store. You may also receive various error messages when you attempt to update your apps on your Mac.
