RavenNevermore Sep 12 Very smooth update. Libertyforall Sep 12 So far so good, no issues on MBP 17" late Jazzyguy Sep 12 The update went in but not so smoothly. Cerniuk Jul 17 Zevrix Jun 13 This update GeogProf Jun 11 Funny, MacUpdate-Lon Jun 10 Sheesh, I must be getting old M85 Jun 8 Apple, what gives?

Ronl Jun 5 Like butter! Jazzyguy Jun 5 The update went extremely smoothly and I like the new version of Safari. Opsono Jun 4 Still ain't fixed the fuzzy icon problem, or the inability for Quicktime Player to make recordings or stay on top of open apps. Libertyforall Jun 4 So far so good on a MBP 17" - finally fixed that annoying iMessage out of order problem!

Donmontalvo Jun 4 So much for a Time Machine "Can't create folder" fix. Vulcan- May 29 Got an Older Mac? GeogProf Apr 13 Koukoish Mar 18 Fixed Safari flickering issues and also surprisingly seems to have a positive affect on battery usage. Seems to have introduced a nasty bug where my display configuration is automatically changed and a phantom VGA monitor is configured in addition to the two monitors actually hooked up to my system.

Spudfry Mar 18 Libertyforall Mar 17 Still having THIS issue on Foulger Mar 16 Why worry about shutdown time? After 14 beta's its probable that Apple have fixed many little niggly bugs, aka undocumented features and overall I feel that this update has been worth the wait. Peter-Van-Den-Einde Mar 15 Finally fixes the slow shutdown time!! Jimmy-D Mar 15 Does anyone know if it fixes the data loss and volume corruption issues that started with Big issue, well documented in the Apple Fora Forums.

ApplesGuy Mar 15 I don't know why there is nothing about WIFI problems. Libertyforall Mar 15 So far so good, but time will tell if the bugs on RavenNevermore Mar 15 Does anyone know if this fixes the super slow Time Machine issue people are having? Ikir Mar 14 I'm already doing some fast test on Fvdg Mar 14 Palmharbor Mar 14 Apple is still consumed with sending pictures etc between iphone, ipad, imac I will pass on this update I have no interest in the esoteric issues of such high concern to apple geeks in Cupertino, CA.

Edgarcabrera Mar 14 On my side, I didn't have problems with Jeff Mar 11 When Apple comes out with a new operating system, I usually wait a few revisions before I install it to make sure Apple has worked out most of the kinks.

Macguruguy Feb 9 I find it very sad that Windows 8 runs faster and smoother on my mac mini than Bigboysdad Jan 27 I do understand that there are other vendors who Apple are competing with but still, the extent to which Apple deliberately makes interaction with those other vendors or their associated software very difficult more so than in previous versions of OS X is an unfortunate feature of Mountain Lion.

Cerniuk Dec 12 A never ending string of bugs and problems. Guest Nov 27 Id-Ego-SuperEgo Nov 26 Can't change Mail. Thedashboard Nov 10 One step forward, ten steps back! Zevrix Nov 6 If you create your own disk images dmg : Pirx Sep 22 Strangely, the install at finish gives me an "install failed" error.

Seems this OS needs a bit more time to shut down the computer. Under General fixes: - Adds a new preference to have Safari launch with previously open webpages I couldn't find it under any Preferences tabs, only "Reopen All Windows from Last Session" under the History menu that's been around since Safari 5.

IroniMAC Sep 20 Just login in to say I like Mountain Lion a lot! Jazzyguy Sep 20 Great update. Nontroppo Sep 20 Lots of little fixes in Macguruguy Sep 20 Working fine here.

OhEssex Sep 19 Mountain Lion is killing me - ever since I upgraded from Lion my WiFi connection integrity is a disaster. I'm not sure why Apple took away the option to restore tabs and browser launch in the first place but it's nice to have it back. Now maybe we can get Snapback and Activity Window back Mysticalos Sep 19 Updating my review: Previously, I had kernel panics when waking from sleep after upgrading to OS X The-Equalizer Sep 3 Is there any way to uninstall this and return my beloved MacBook Pro back to its original, fast, smooth, un-choppy, stable self?

I-love-Apple Aug 30 Mahjun Aug 26 Skyhorse Aug 25 Utter trash Mac Aug 24 This update was incredibly fast as compared to previous OS updates. RunHomeSlow Aug 24 No problem for me with Pepper Aug 24 Lion users can try the beta version of Messages which is the same as iMessage on iOS but the final stable version only works on Mountain Lion.

Time Machine now allows you to select more than one hard drive to save backups. Time Machine can now also run in PowerNap mode, which allows the operating system to update itself while the computer is sleeping. Software updates are now fully integrated with the Mac App Store and can be downloaded directly.

Game Center is the same as on iOS. Gaming is becoming increasingly important on OS X and Game Center allows you to download games, play against friends and save your progress. AirPlay will allow Mac and iOS users to play against one another. Additional integration with Facebook includes being able to "like" individual games and challenge friends to beat your high scores.

Mountain Lion extends the capabilities of Mountain Lion allowing the synchronization of documents too. In addition, your Facebook friends' contact information and profile pictures will now appear in Contacts as well. Three clicks have been replaced by one. It was followed by a faster and more subtly improved Snow Leopard Naturally, this increasing move towards iOS will delight those that love using their iPhone and iPad.

Those that prefer their mobile device and Mac to be treated as mainly separate user experiences, may not be so enthusiastic but Mountain Lion provides some great new functionality and is well worth the upgrade from Lion.
