Mountain lion freezes notifications on screen

My notification center shows me some messages as little windows on top right of my screen. But when I try to close them with the mouse it turns on that color wheel and does nothing! So they remain opened. The only way to make them disappear (and use the notification center) is to log out and log in again.
How could I resolve this and why is this happening?
Thanks.

The next time you have the problem, note the exact time: hour, minute, second.
If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Scroll back in the log to the time you noted above. Select any messages timestamped from then until the end of the episode. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.

My mail app in Mountain Lion freezes

My mail app in Mountain Lion freezes a few second to a few minutes after launching. I have already re-installed the OS but it didn't help. Any thoughts?
I have one exchange account that I have removed and reinstalled. I've tried to see if it's conflicting with any of my other apps, I can't find anything there either. Never had this problem before, but would like use of this app. Thanks.
Mark

More info. It seems to freeze when switching between mail and other apps. It then becomes impossible to switch back to the mail app, though mail will be indicated in the app name just to the right of the apple menu

Mountain lion update = Black flickering screen + freeze :S

so i have a late 2009 mac mini and i decided id download mountain lion, about a day after the download every time i opened certain programs my screen would flicker black about 10 times really quickly and then my whole computer would freeze except for my mouse. Fixies please

Hello,
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Mountain Lion freezes, full screen lagging, and makes the Macbook HOT!!

hello everyones,
have you guys experience this before after installing Mountain Lion OSX?
I'm quite dissapointed my machine feels hot and I thingk if i put an egg it will cook.
I already dim the brightness.safari problem, mail problem,
chrome crash and not smooth.
how to solve these problems?

Man, do you have Sophos antivirus? If that so, you need to uninstall it the right way:
For Sophos Anti-Virus for Mac OS X version 7.x , go to Macintosh HD|Library|Sophos Anti-Virus.
Select 'Remove Sophos Anti-Virus.pkg'.
Follow the instructions on the screen.
NOTE, if you are running Sophos Anti-Virus for Mac OS X version 4.x, the path in step 1 is Macintosh HD|Library|Application Support|Sophos Anti-Virus.
It seems that Sophos antivirus is crashing ML. They have an update but I'll wait some time becuase I've really had a painful time these days.

Mountain lion freezes

I upgraded to mountain lion but applications start to freeze whenever oppening app store, clicking share button on safari , signing in into twitter from system preferences , I verified disk + permissions and repaired them, but this did not solve the problem, can you need help me in this issue?

Hi to everyone. I would just like to post how I think might have solved the freezing issue of Mountain Lion. I have posted in this thread a couple of weeks passed and I still see some do experience freezing still.
I have a Macbook Pro 13" late 2011 preinstalled with OS X Lion. I installed Mountain Lion last July 26 directly from MacUpdate when all **** started. Apps crashed. Screen Froze etc.
I have read most and did what have been suggested here but failed to solve the issue. And calling Apple would is in no way an option for me since I am from Manila, Philippines. Besides some of you even mentioned calling them lead to no solution. So I thought, given the hours people waisted calling up on Apple, why not do a clean install instead. Hours spent installing is better than waisting up on Apple's genius without any luck.
Clean install did fix the problem.
STEPS:
1. Back up your files (pictures, documents, music, movies. Do not include your apps (may it be 3rd party software or from macappstore). You may opt to use Time Machine but when it comes to restoring it back, do not restore the entire backup. What I did was just to restore my Music, Movies, Pictures.
2. Restart Mac and boot via USB (with Mountain Lion installer).
3. Reformat your hardrive with Disk Utility. Then install Mountain Lion 10.8
4. Update via macappstore to 10.8.1
5. Restore your files manually or choose the folders via Time Machine.
6. Then install all your other apps.
7. Finish!
I hope this helps. I haven't had any issues to date.
After a clean install, no freezing will ever be experienced, a 30 second boot up time, 5 seconds to shutdown my mac, and a manageable 5 hour battery life.

ITunes makes Mountain Lion Freeze - Please Help

Hi there: Mountain Lion seems rock solid on my mac pro except when I listen to music with iTunes - it will freeze the system (no more music, just a frozen screen saver)... Power cycle (holding down the power button) is the only way to unfreeze it... All other apps run just fine with no issues. Also, I'm connected to airport express via ethernet, not wifi. Has anyone seen this problem before? Please advise and thank you very much!

I have the exact same problem except on a imac, with 16G ram. Also not hooked to WiFi. I have an app called Logic Pro (music maker) and I wonder if that is causing it

Mountain Lion Freezes and crashes Safari.

Tried to download Mountain Lion to my Mac Desktop but it freezes after 53mb.
Now when I try to open Safari it says it aborted unexpectedly and advise to click reopen.
When I do this it just takes me back to the error message page.
Anyone care to help / advise?

First run the two resets and then try Safe Mode

Mountain lion freezes during installation with 34 mins remaining

Hi all,
My upgrade to mountain lion (from lion) freezes almost immediately when it hits the 'install os x' screen. It shows only the smallest possible progress in the progress bar and time remaining is stuck at 'about 34 minutes'. My mbp bought in 2010 rumbles as if doing something, but has been making this sound with no apparent progress for over 45 mins now. How do i get out of this freeze situation?
Thanks!
Mark

Follow-up:
Ok, after more than an hour 'time remaining' changed to 33 minutes and 15 mins later to 28. The progress bar also started showing progress. Strangely enough it then changed back to 31 mins and less progress (but at least it started showing something). Just hope this is not an indication the the new os has lost the ability to tell time...

Mountain Lion Freezes 30 Seconds Every Hour

I've recently migrated from a Mac Pro running Lion to a MacBook Pro running Mountain Lion. I migrated using a Time Machine backup and to make a long story short, it was an ordeal, but I've got everything running smoothly now… Everything except for one thing.
Once an hour, everything but the mouse freezes. The clock stops. If time machine is backing up, the backup icon stops moving. Everything stops for about 30 seconds and returns to normal. It happens very consistently on the same minute and the same second every time until a reboot and the one hour clock starts ticking anew from my boot up time.
I thought that maybe Time Machine was the culprit here, but I turned that off and freezes continued happening. Also, there is nothing in my log files that show anything happening at the time of each freeze. This is driving me nuts.
Any help would be appreciated.

How to maintain a Mac
1. Make redundant backups, keeping at least one off site at all times. One backup is not enough. Don’t back up your backups; make them independent of each other. Don’t rely completely on any single backup method, such as Time Machine. If you get an indication that a backup has failed, don't ignore it.
2. Keep your software up to date. In the Software Update preference pane, you can configure automatic notifications of updates to OS X and other Mac App Store products. Some third-party applications from other sources have a similar feature, if you don’t mind letting them phone home. Otherwise you have to check yourself on a regular basis. This is especially important for complex software that modifies the operating system, such as device drivers. Before installing any Apple update, you must check that all such modifications that you use are compatible.
3. Don't install crapware, such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” “extenders,” “cleaners,” "tune-ups," “defragmenters,” “firewalls,” "barriers," “guardians,” “defenders,” “protectors,” most “plugins,” commercial "virus scanners,” "disk tools," or "utilities." With very few exceptions, this sort of stuff is useless, or worse than useless.
The more actively promoted the product, the more likely it is to be garbage. The most extreme example is the “MacKeeper” scam.
As a rule, the only software you should install is that which directly enables you to do the things you use a computer for — such as creating, communicating, and playing — and does not modify the way other software works. Never install any third-party software unless you know how to uninstall it.
The free anti-malware application ClamXav is not crap, and although it’s not routinely needed, it may be useful in some environments, such as a mixed Mac-Windows enterprise network.
4. Beware of trojans. A trojan is malicious software (“malware”) that the user is duped into installing voluntarily. Such attacks were rare on the Mac platform until sometime in 2011, but are now increasingly common, and increasingly dangerous.
There is some built-in protection against downloading malware, but you can’t rely on it — the attackers are always at least one day ahead of the defense. You can’t rely on third-party protection either. What you can rely on is common-sense awareness — not paranoia, which only makes you more vulnerable.
Never install software from an untrustworthy or unknown source. If in doubt, do some research. Any website that prompts you to install a “codec” or “plugin” that comes from the same site, or an unknown site, is untrustworthy. Software with a corporate brand, such as Adobe Flash Player, must be acquired directly from the developer. No intermediary is acceptable, and don’t trust links unless you know how to parse them. Any file that is automatically downloaded from a web page without your having requested it should go straight into the Trash. A website that claims you have a “virus,” or that anything else is wrong with your computer, is rogue.
In OS X 10.7.5 or later, downloaded applications that have not been digitally signed by a developer registered with Apple are blocked from loading by default. The block can be overridden, but think carefully before you do so.
Because of recurring security issues in Java, it’s best to disable it in your web browsers, if it’s installed. Few websites have Java content nowadays, so you won’t be missing much. This action is mandatory if you’re running any version of OS X older than 10.6.8 with the latest Java update. Note: Java has nothing to do with JavaScript, despite the similar names. Don't install Java unless you're sure you need it. Most users don't.
5. Don't fill up your boot volume. A common mistake is adding more and more large files to your home folder until you start to get warnings that you're out of space, which may be followed in short order by a boot failure. This is more prone to happen on the newer Mac notebooks that come with an internal SSD instead of the traditional hard drive. The drive can be very nearly full before you become aware of the problem. While it's not true that you should or must keep any particular percentage of space free, you should monitor your storage consumption and make sure you're not in immediate danger of using it up. According to Apple documentation, you need at least 9 GB of free space on the startup volume for normal operation.
Use a tool such as the free application OmniDiskSweeper to explore your volume and find out what's taking up the most space. Move rarely-used large files to secondary storage.
6. Relax, don’t do it. Besides the above, no routine maintenance is necessary or beneficial for the vast majority of users; specifically not “cleaning caches,” “zapping the PRAM,” "resetting the SMC," “rebuilding the directory,” “running periodic scripts,” “deleting log files,” “scanning for viruses,” or “repairing permissions.” Such measures are for solving problems as they arise, not for maintenance.
The very height of futility is running an expensive third-party application called “Disk Warrior” when nothing is wrong, or even when something is wrong and you have backups, which you must have. Disk Warrior is a data-salvage tool, not a maintenance tool, and you will never need it if your backups are adequate. Don’t waste money on it or anything like it.

Mountain Lion Freezes From Sleep Mode

It seems like Mountain Lion is going into this "kernel" panic mode after I try to bring my computer back from sleep mode. That thing everyone a lot of people talking about where it locks up and you can't force quit anything or do anything except watch the spinning beach ball and move between open applications.

For what its worth I have tried removing all peripherals and see if it does it and it still does it.   This behavior doesn't happen to me at all while using the machine normally, only when I am coming back from sleep mode.   When I upgraded it didn't list any incompatible software.    Also I am noting that after a few trys I can relaunch finder but the spinning beach ball remains.   I was thinking that it was something like Windows Explorer crashing but it seems lower level problem then that.   There is something hanging and it doesn't seem like an application.   Seems like something in the OS, well, obviously because this wasn't happening before I upgraded.   I am just going to shut my machine down after I am doing using it for now so I am not hard resetting it four times per day. Has anyone else seen this behavior?

Okay, it has been over 30 hours since my iMac has done this.    It doesn't have that problem where it sits and spins any more.   My workaround is to go into System Preferences, Energy Saver, and slide the Computer Sleep all the way to NEVER.   I still put my display to sleep same time though. And I also uncheck Put Hard Disks to Sleep When Possible.    That seems to have done the trick for me.    I have done nothing else to remedy this and my rig would freeze up on my three times per day so there you have it.    Hopefully they will fix whatever issue is plaguing the sleeping computers.   I know there are alot of them out there set that why by default.

Macbook Pro Retina Mountain lion freezes after deep sleep

Hello All,
I am having a strange problem with my MacBook Pro Retina, Mid 2012 (Mountain Lion 10.8.3). Since about January time It keeps crashing after I put it into a deep sleep. After closing the lid - waiting for 1 hour or so - then reopening the lid, i get presented with the normal Apple login screen (breifly) and then it crashes and i get a grey screen saying my mac has had an issue and it needs to restart.
When i log back on i get an error message that I can send onto Apple and then my Mac carries on as normal. Very weird.
I have searched these forums, been into the Apple store, spoken to Apple done hardware diagnostics, reinstalled the OS (worked breifly then stopped working again) - so i assume its one of the programs or bits of hardware that i use (which i have tried to isolate/remove)- but i am still strugling to solve these issues.
It would be great if someone could give me some advice around:
1. Where I can find these log files/error messages, etc.
2. Understanding what it is causing this issue.
Thanks in advance.

The solution is to dump the 100€ mini-display port DVI-D adapter that apple sells and buy a mini-Display to Display-Port cable for 6€. No crashes, no annoying interruption of the display (which I had several times the day for 2 or 3 seconds). There are very short interruptions now, but it is much better than with the apple adapter. The apple adapter needs a USB port, which is not necessary with the simple cable.
As for the monitor: Burn In, otherwise great. The burn in can be erased via monitor menu but should not be there in the first place.
Hope this helps.

Mountain lion really bright white screen on boot?

Since I installed Mountain Lion I can't seem to get rid of the really bright white screen with Apple logo at bootup.
I RESET the PRAM and it will work for one boot and then go back to the really bright screen burning my irises out.
It can't be the battery because my computer keeps the time and date correctly.
I have also checked the STARTUP Disc and that is working right too. I even tried redoing permissions through Disk Utility and that didn't help.
Anyone have any ideas on this one?
Thanks.

Anyone have a answer to this?
