Imac freezes in Mountain Lion
Having installed Mt. Lion many months ago, in the last week, my imac is freezing both in Mail and in screen saver. Any workarounds?
Same problem. iMac, mountain lion, 8GB RAM. Screen and keyboard freeze. Sometimes I can move the mouse pointer but here is no response to clicks.

Imac freezing- running Mountain Lion 10.8.4
Hi all - Running Mountain Lion 10.8.4 on an Imac 2.4ghz Intel Core 2 Duo with 3gb RAM. Have recently (last 2 weeks) started to get problems with system freezing on waking up from sleep, only way to cure is to force shut programs then turn off pc and reboot. Have scanned the net for similar problems and found that it seem to be becoming a common one, followed various bits of advice and have found that using the console feature and the logs it provides that my problem seems to originate with Time Machine. I had gone through the process of removing all my peripherals except TM and started to read the diagnostic logs on console for a common thread and noticed that there were constant references to Tm (see below) and backup alias.

Not starting Time Machine backup after wake - failed to resolve alias to backup volume.
I decided to disconnect my TM and see what the result was - firstly I noticed there was a definite increase in the speed of my system and secondly that if I let the system go to sleep by itself when woken it worked fine, however if I forced sleep it froze on waking up, below is snapshot of the log at 3.00am in the morning

Appreciate that this possibly relates to me not having the TM connected - will reconnect and see what the result is and follow up.
I have spoken to our local Apple shop however they have not heard of the problem! The advice given is to save everything and do a clean install, however have noted on the net that this is not necessarily the answer to the problem. Am a bit loath to place my Imac in the shop for many hours work and not necessarily get the problem solved.
So any ideas as to where I go from here please!
Many thanks
BMake a "Genius" appointment at an Apple Store, or go to another authorized service center.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

*An SSD doesn't need to be zeroed. -
This may be the same issue as some other discussions but I have a few different circumstances. I upgraded to Mountain Lion a few weeks ago and all seemed to be ok. Then I got an upgrade notice for Itunes last week and installed the update. Since then My mac started freezing after coming out of sleep mode. The mouse was active but when i selected programs from the dock the icons would just bounce and nothing would open.The only way to revive it was to do a restart with the power button. Then the system would be fine until it went into sleep mode .After reading through several disussions it seems many people are having similar issues with very few fixes to the problem. I am not very savvy on mac O/S so I am in the dark as to where to begin to troubleshoot this problem. Since the freeze ups always occur after coming out of sleep mode I set my computer to never sleep which has worked to stop the freezing but I am not sure how good it is for my system to be running all the time. I would appreciate any input on this problem. My Imac is a 2008 intel with 3 gig ram
Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test. -
IMac freezing after Mountain Lion Upgrade
After upgrading my iMac to Mountain Lion it is freezing at least one a day. Sometimes the screen get messed up right before getting frozen, something like this video (from another guy), but they move from top to bottom to me.
I never had this problem before, it started right after the Mountain Lion upgrade.
Anyone with the same problem? Any ideas?Permissions Repair:
Go to applications then to the "other" folder then go to disk utility, on the left hand side you will see a white box. Select the second option, usually called "mac HD" with that selected click on "repair permissions" in the center towards the bottom of the screen. Wait for it to complete, then see if this fixes the issue.
PRAM Reset:
1- Ensure the machine is powered off.
2- Locate the following keys on your keyboard in preparation for Step 4:
‘command’ – ‘option’ – ‘P’ – ‘R’
3- Press the ‘power on’ button.
4- Immediately – and before the grey screen appears – hold down ‘command-option-P-R’ all together.
5- Keep them held down until you’ve heard the start-up chime twice. After you release them you should hear it again, and hopefully your Mac will boot up normally -
I have a free agent desk 500 GB external hard drive. Since updating my iMac OS to Mountain Lion it no longer backs up through Time Maching like it did in the past. Now, after completing its work it says, "Unable to complete backup. An error occurred while creating the backup folder." I cannot find any sites that help me fix this. Do I need to purchase a new external hard drive?

my imac is running mountain lion and last night i downloaded maverick. in midst of installing it, it said a powerPC app microsoft word would not work so i canceled the install for the time being. my questions is if i choose to finish installing maverick does that mean i will nevver be able to access word documents stored on my desktop? or do the word docs automatically convert to pages or what? i am so confused. would i be better off just sticking with mountain lion and send the maverick install to the trash? hoping someone will be able to answer my question though i am afraid the response is likely to be just stick with mountain lion so you can keep using word. i had been looking forward to maverick but it seems pretty drastic to not have access to microsoft word anymore by switching to maverick. hope someone has an answer so i can have the best of both worlds so to speak!
thanks for your response Csound1 on the peninsula ... if i go ahead and install maverick and then download LibreOffice or OpenOffice will i then be able to access old microsoft word saved documents on my deskstop through those two free alternatives? i am not that knowledgeable about these things so i am not sure if you are saying i will just be able to use libreoffice or openoffice for creating new documents or whether i can access the saved microsoft docs? are they transferred to OO or LO or what and if editing of the old word docs is needed can i do that through the OO and LO programs or apps (see i am not even sure if i am using the correct vocabulary!) hope you can answer this as quick as the first question, so i can decide to stick with mountain lion and trash the maverick install or proceed with maverick install and hoppe that my microsoft word docs are still accessible through OO or LO or adding to myquestion will pages on maverick be able to open the old word documents? thanks again!

Is there any Blu-ray Player Software compatible with my iMac OS X Mountain Lion?
I want to watch a Blu-ray Movie on my iMac(OS X Mountain Lion), so I need a best Blu-ray Player Software.
You need third party software, Macgo Blu-ray Player can deal with the work you mentioned. As for the Mac Moutain Lion(10.8), I check their website and it is said that the Mac OS 10.8 are supported.
Refers to their product page: http://www.macblurayplayer.com/features.htm -
I want to upgrade my 2006imac with 3GB ram but mountain lion requires 4gb. Can I purchase mountain lion in the app store and it will install lion or will it just charge me $20 for an OS I can't use?
A 2006 iMac cannot run Mountain Lion at all. Mountain Lion only requires 2 GB of RAM, but your model has a video controller which doesn't support features required by Mountain Lion, so Mountain Lion does not support your model. The earliest iMac which can run Lion is the mid 2007 model (aluminium body). A full list of supported models is available here.
If you attempt to buy Mountain Lion in the App Store using your 2006 iMac, the sale will not proceed and you will get an error message saying you cannot purchase Mountain Lion because it is not compatible with your computer. You will not be charged.
If you are currently running Snow Leopard and want to upgrade to Lion, but didn't already purchase Lion (e.g. for use on another computer), it is apparently possible to place a special order for Lion via a telephone call to Apple Customer Support. (I say "apparently" because there have been reports that Apple told some people this was the correct solution, but early attempts to place an order were refused with Apple Support claiming they weren't selling Lion at all. I think this was a temporary situation and it should be resolved by now.) There are links to support telephone numbers here.
Apple will charge you the standard retail price for Lion (e.g. US$29.99 in the US) and supply you with a "redeem code" for the App Store. That is entered by going to the Featured category in the toolbar, and clicking Redeem under the Quick Links heading on the right side. Once your code is redeemed, Lion will be added to the list of purchases for your Apple ID, and you can download and install it.
If you had already bought Lion for use on another computer, you can re-download it from the Purchases list in App Store, but there might be a couple of catches:
1. Some people have found that Lion was added to their list of hidden purchases. You need to unhide it first. Do this by going to your Account page (under Quick Links, or "View My Account" under the Store menu in the menu bar). If you have hidden purchases, there will be a "View Hidden Purchases" link, and from there you can unhide Lion.
2. If you are running Lion and want to redownload the installer on that computer, you may need to hold down the Option key when clicking on the Purchases heading in the toolbar, to enable the download button for Lion. -

Mine is 10.6.8 (SnowLeoaprd)
10.7.x is Lion
10.8.x is Mountain Lion -
Receiving message "your Mac OSX start up disc has no more space available for application memory."
This has just started in past week, I removed about 6 apps from dock to see if it cleared it but message still appears. Mac is iMac 5 with Mountain Lion (10.8.4)
Would appreciate some help.
BarbThe message has nothing to do with available disk space. There is excessive swapping of data between physical memory and virtual memory.
That can happen for two reasons:
You have a long-running process with a memory leak (i.e., a bug), or
You don't have enough memory installed for your usage pattern.
Tracking down a memory leak can be difficult, and it may come down to a process of elimination.
In the Activity Monitor application, select All Processes from the menu in the toolbar, if not already selected. Click the heading of the Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
View ▹ Columns ▹ Real Memory
from the menu bar.
If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more real memory over time without ever releasing it. Here is an example of how it's done.
The process named "Safari Web Content" renders web pages for Safari and other applications. It uses a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider it a prime suspect.
If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:
sudo leaks -nocontext -nostacks process | grep total
where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details. -
My Imac 27 keeps freezing since Mountain Lion installed
Is anyone else have freezing problems I have 8gbram i7 2.8ghz no help from tech support.
Morning, glad things are going ok .
I haven't re-installed Sophos yet. The Sophos forum are saying there's still an issue, so until I hear that they have resolved it, I'm leaving it uninstalled.
Under Lion, it used to run in the background with minimal resources being used. I hope Sophos can get the issue resolved ASAP for Mountain Lion.
