Macbook randomly shuts down after installing Mountain Lion.

I have a late 2008 Aluminum Macbook; as of last week I have installed Mountain Lion finally and I've come across a rather irritating problem: the laptop keeps randomly shutting down. I've noticed it primarily likes to go down when the battery is at 89%. I've never had battery trouble before, this happens even when the computer is not over-heating, so I'm fairly certain it's not a battery issue. After restarting the computer all the applications I was using are still open and any progression I had made on documents have been saved since the time of the crash.
I'm really at a loss as to what's going on with this. Has anyone experienced something like this or have any suggestions as to how to fix this?

Hi ppl again :)
I found that screen is not disabled, it is only have a very low brightness. So I begin to wait because I saw that actually installer is still running. Finally, Mas OS was installed and after that I change brightness using keyboard (it didn't worked while installation). Now all is ok. I also tried to reboot and system loaded correctly.
I hope this will help. Unfortunatelly Apple support was unable to help me by a phone call.
Have a nice day!

My mac mini doesn't shut down after installing mountain lion?

Right after i installed mountain lion and checked all the new features, I closed all applications, clear ram, clear cache, clear print queue, made sure that nothing was running when i logged out(only one 1 user was logged on.) I shut down and it seemed normal until the mac mini restarted, saying there was a problem and the normal error report appeared on screen when everything rebooted(after I log back on.) I'm angry. Really what should I do, I just bought this on December 2011( i7 mac mini sandy bridge) of last year. I hope apple releases an update to fix this problem.
My first attempt was to go to disk utility and fixed it, it worked I was able to shut down. However after that it started to go back to the way it was and it still wont shut down. Yes Im able to do everything else like put the hardrive to sleep(yes it goes to sleep I made sure) and force closing applications. Right now Im going to attempt doing what I did before but I will appreciate if a representaive or an apple veteran would give me advice or some useful information on how to fix this problem.
This happened 8/18/2012 at 6:57(when I installed Mountain lion and checked.)

Hi Ted,
At this point I think you should get Applejack...

Ignore the MacKeeper ad no matter what else you decide.
After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
applejack AUTO
Then let it do all 6 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 6 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
Trash old Log files.
First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files! :-)
Disconnect the USB cable from any Uninterruptible Power Supply so the system doesn't shut down in the middle of the process.
Just sits there occupying very little space & never interfering, unless you need to invoke it in Single User Mode.

IMac keep shutting down after installing OSX lion

Hi,
I have a mid 2010 27 inch i5 machine and after I had installed OSX Lion last month the machine randomly shut itself down while I'm using it. At first I thought it was because of a software problem with Final Cut Pro X, since I installed that at the same time and it would shut down while I was using it. Then it start to shut down while I'm just browsing the net. Restarting is not a problem but a pain to loose unsafe data when it crashes.
Does anybody else have this problem? Again the machine was working fine before OSX Lion so I don't think it's a hardware issue. On average it would shutdown once or twice per usage day sometime a few minutes after turning on the machine, still cool, and sometime after a while, not excessively hot.
Appreciate any help and thank you in advance!

Why is my MacBook Pro very slow after installing Mountain Lion 10.8.5. - Solutions?

Hello, hello
After waiting quite a while - I paid the relatively small amount, and got myselves a new OS.
But I am very disappointed of the speed - I see that this also was a problem with OS Lion?
Please assist me. Perhaps others have this problem as well?
Some info:
- 2,66 GHz Intel Core i7 processor
- 4 GB 1067 MHz DDR3
Also
- Sometimes I run the Parallels Desktop 6 and 9 software, does this affect specs of the new OS?
Hope to hear from you guys.
Sincerely,
Harald

With only 4GB of RAM, how much do you have devoted to the virtual machine running under Parallels? Even if it's a small amount, it's going to make page outs and swaps used very high. From my perspective, 8GB of RAM is the 'sweet spot' for running Mountain Lion.
I'm assuming that you've a 15" mid-2010 MacBook Pro? If so, you can speed things up by installing the maximum 8GB of RAM. Go RAM shopping at Crucial or OWC.
Other than upgrading your RAM, the only thing that you can do to speed up your machine is to install a SSD. You can also check the SSDs at Crucial and OWC and decide if one is right for you.

System slow down after installing Mountain Lion OS

I recently purchased a MacBook Pro for school, and upgraded the OS to Mountain Lion. I noticed a slight slow down in the computer. Is this normal, or is there something I can do to speed it back up?
SW

Your processor is alright however the specs on your machine are lackluster. It has a slow drive and not enough ram. Your first problem is that with that little ram the computer will use the drive for paging. Since the drive is 5400 (the slowest hard drives in the world) your going to be waiting.. a lot. Up your ram and upgrade to a 7200 rpm hard drive youll be happy. If you really want a gem system upgrade to 8gb ram and get a swift SSD drive.
Its a technology problem, not an OS problem. Newer OS's have extra features that capitalize on modern tech.. 5400rpm tech are like.. 90s tech... Cant believe they were selling those right up to 2011 or whenever.. criminal...

Major slow down after installing mountain lion

....just my bought my new Mac last Christmas ,coming from Windows was a major change,everything was fast,
then a few days ago I upgraded from OS Lion to Mountain Lion and now everything slow down a lot.
Everything a try to open from internet browsers to apps,it takes from 30 seconds up to 1 minute and a half.
Is there anything I can do to return to OS Lion and have the same speed as before?

Did you run a Time Machine back up before you updated?

Internet down after installing mountain lion

I just upgraded to Mountain Lion, and now I'm getting a message that my DNS lookup failed when I try to load a web page. My internet is working properly otherwise. I did enter the open DNS values
208.67.222.222 + 208.67.220.220
but this did not fix the problem.

Hi, this has worked for a few...
Make a New Location, Using network locations in Mac OS X ...
http://support.apple.com/kb/HT2712
10.7…
System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.
10.5.x/10.6.x/10.7.x instructions...
System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
The interface that connects to the Internet should be dragged to the top of the list.
Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.
For 10.5/10.6, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...
208.67.222.222
208.67.220.220
Click OK.
Also, turn off IPv6:

Ive just upgraded my late 2009 macbook, and things are not working properly. First of all, when I started the computer first time after installing Mountain Lion, some message advised me that some files were impossible to install.

Ive just upgraded my late 2009 macbook, and things are not working properly. First of all, when I started the computer first time after installing Mountain Lion, some message advised me that some files were impossible to install. Once I wrote my password, and for now on, everytime I start the session, another window advise me that "Java SE 6" is missing, due that, the computer can't run some "CS5Service Manager". If I try to install it, the download ends with an error. If finally, you skip the istallation, you arrive to the dock, but the menu bar at the top of the screen doesn't show up.
In addition, my trackpad doesn't works either. I can move the arrow but i can't click anywhere, probably because the option of clicking by touching is disabeled and I can't performance a regular click.
I'll be very glad if someone know what the heck is happening with my computer. Anyway, I'm going to the genius bar next Saturday. Thx!

We're sorry.
We can't find the article you're looking for.
Please return to the Apple Support homepage.
Sigh.

My macbook pro is very slow after installing mountain lion

my macbook pro is very slow after installing mountain lion? Is anyone else having this issue?

If you don't use an SSD and bump your RAM up to 8 Gb's you may experience slow speeds, but I noticed slow speeds with your general configuration in SL.
one thing you should consider right now is, Spotlight is Reindexing your hard drive, that takes time and resources, (resources which you don't necessarily have to spare).
If you continue feeling like your performance is slow, you have a few options with this computer (I have the same one).
the express card slot can house a wintec SSD drive. That little door on the side of your machine is pure gold for a really quick solution for speeding up your machine. I have one in mine right now i'm using as a scratch disk for CS6 but I used to boot from it, and the speed boost was out of this world.
You could take out the internal HDD and put in a new SSD (I have a Vertex 4 from OCZ) it is completely over kill but my experience is pretty fast and I keep up with the later MBP models colleagues have.
There are some other options for you like taking out the optical drive (however I don't know if I'm supposed to talk about that here). Google Data Doubler.
You need to also set it to always use the 9600 chipset, this will increase performance a lot too. to do this go to system preferences>energy saver>Better Performance. This switches the video card to the better one and makes a world of difference.
Lastly, your RAM. after an EFI Firmware update, our computer support up to 8GBs of RAM. Do it!

Many of my System Preferences will no longer work after installing Mountain Lion. Software update, startup disk, iCloud, etc. no longer will launch. I keep getting a drop down window saying I must restart system preferences in order to use. No go!

Many of my System Preferences will no longer work after installing Mountain Lion. Software Update, Startup Disk, iCloud, Time Machine, Notifications, etc. no longer will launch even though they do show their icons in the system preferences window. I keep getting a drop down window saying I must restart system preferences in order to use with a "Cancel" or "OK" choice. After I click on "OK" the window just keeps reappearing with the same choices and the pane I wish to use still remains inoperative. Third party preference panes DO work.
Reinstalling OSX Mountain Lion did not help. Neither did throwing away preferences.plist.

Hi Jeff,
Tried to reply with my iPhone but not easy! Anyway, back on the laptop now. Yes the crash was bad but Tek support at Prism Sound was really good. In the end I rebuilt the whole system on a new disk which took a couple of days with all the plugins, softsynths etc.... but there seemed to be no alternative in my case, and this was agreed with Prism sound as being the only alternative left to me. I still don't really know what caused the crash but ML and Orpheus are both working fine now. Let's face it, you'll have to update at sometime..maybe best to pick some time between projects On balance, I suspect that my problems were unique to my system and that your installation will go ok.
Hope it goes well,
Rick

Final Cut Pro X after installing Mountain Lion I have lost some of the "additional content" which was available by clicking on "Download Additional Content" in the roll down from "Final cut Pro". Now this feature takes you to store update?

Final Cut Pro X after installing Mountain Lion I have lost some of the "additional content" which was available by clicking on "Download Additional Content" in the roll down from "Final cut Pro". Now this feature takes you to Apple store update? which produces nothing! How can I download these free sound and music files, what has happened? Please help as there is nothing on the apple site to cover this??

HT1338 Why is my MacBook Pro running so slow after installing Mountain Lion 10.8.

Why is my MacBook Pro running so slow after installing Mountain Lion 10.8. I have restarted, created more free space on my hard drive and run disk utilities. Simple operations result 20 seconds or more of the spinning wheel. Some are so slow that the operation does not happen at all. Itunes music cuts out during operations.

Check out this article by Thomas Reed for help http://www.reedcorner.net/understanding-upgrade-nightmares/. Also, make sure all apps are compatible with Mountain Lion using www.roaringapps.com. Do you have any antivirus installed? Make sure all apps are updated as well.

MacBook Air late 2010 very hot after installing Mountain Lion? Can i back to Lion?

My MacBook Air, late 2010, is very hot and the vans are going too speedy after installing Mountain Lion. Can I deinstalling Mountain Lion and returno to Lion? What are the steps for this deinstallation? Thank you.

Technically, there is a way, but it is definitely not something I would recommend, as downgrading isn't usually supported/encouraged.
I found a website that has instructions but it clearly states it's not for the inexpert, so proceed at your own risk. Also, I don't think you can download Lion from the AppStore anymore?

My wifi is very slow after installing mountain lion on my Mac book pro

My wifi is very very slow after installing mountain lion on my MacBook pro.
What can I do?

Ha ha, I misread that as "My wife is very slow after installing mountain lion on my Mac book pro"
BTW on my MBPro (late 2009 with max RAM) Mountain Lion runs very well with no slowing down.
