How to determine if I can upgrade my iMAC to Mountain Lion
I believe my iMac 24" is mid 2007 or later but need to make sure it is before I attempt to upgrade to Mountain Lion.

I upgraded my iMac to Mountain Lion and it has been painfully slow ever since. Any ideas on what might be happening and how to fix it?
First, back up all data immediately, as your boot drive might be failing.
There are a few other possible causes of generalized slow performance that you can rule out easily.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Otherwise, take the steps below when you notice the slowdown.
Step 1
Launch the Activity Monitor 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 Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 2
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. 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. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long. -
I upgraded my iMac to Mountain Lion and now my Canon Pixima MP500 will not open because PowerPC apps are no longer supported! Has anyone experience this problem?
Correct. Applications designed to run on the old PPC Macs (which Apple stopped making in 2005) cannot run on Mountain Lion.
You need to update your printer driver:

I am wanting to upgrade my iMac to Mountain Lion... a few questions first...
Machine Specs
Model Name: iMac
Model Identifier: iMac9,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.66 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 6 MB
Memory: 4 GB
Bus Speed: 1.07 GHz
So basically I am wanting to make sure I am compatible(pretty certain I am)
And if so, do I need to backup everything?
I have had this machine for several years, so there is much I would need to backup.
I have recently picked up a MacBook Pro, and upgraded tonight to OSX Mountain Lion, everything was fine and still here after install, incl all my programs.
There wasnt much on it so I wasnt bothered if it did get wiped.
I am basically wanting to setup my WDig 2TB Ext HD to run as my media storage and run my music player to play FROM that, to free up disc space and make my machine run better
Hopefully there's not "too much meat in the sandwich" there but hoping someone(s) can help out.If you don't have backups, you need to make some ASAP, preferably even before you finish reading the rest of this message! And you certainly should do so before even considering something like installing a major system upgrade.
As to compatibility, I believe that machine should be compatible, but the easiest way to find out for sure is to just try buying Mountain Lion on the App Store. If the machine isn't compatible, it won't let you, as I understand it. -
Where did you buy this laptop? I know if I opened a box expecing and having paid for a 2012 model and found a 2010 model, I'd be back at the store demanding an exchange quicker than you could imagine. Open box or not, if you thought you were buying a 2012 model, you should get what you paid for.

I hv lost my icon for iphoto on my Imac Mac OSX10.5.8. I still hv my pics but can no longer creat albums and events. If I upgrade to the latest Mountain Lion, will my pics go into the new iphoto?
From where did you lose the iPhoto icon? From the Dock? If so, then it's still in your Applications folder. Find it there then drag the icon back into the Dock. If it's no longer in Applications perhaps you've moved or renamed it. Use Spotlight to search for "iphoto."
Upgrading to Mountain Lion will not affect your iPhoto Library unless you erase the hard drive first. Be sure you backup before any system upgrade.
Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
Snow Leopard General Requirements
1. Mac computer with an Intel processor
2. 1GB of memory
3. 5GB of available disk space
4. DVD drive for installation
5. Some features require a compatible Internet service provider;
fees may apply.
6. Some features require Apple’s MobileMe service; fees and
terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
Lion System Requirements
1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,

How do I get MS Office 2011 to work on Mountain Lion?
I recently upgraded my iMac to Mountain Lion and now I can't use any of my Microsoft Office 2011 applications. I downloaded the new Auto Update from Microsoft, but since I am unable to open any Microsoft Office applications, I'm not able to run the autoupdate.
Is there anyone who knows how to get it to work again?This is less painful:
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, EasyFind 4.9, instead.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
AppZapper 2.0.1
AppDelete 3.2.6
Automaton 1.50
Hazel
AppCleaner 2.1.0
CleanApp
iTrash 1.8.2
Amnesia
Uninstaller 1.15.1
Spring Cleaning 11.0.1
Look for them at VersionTracker or MacUpdate.

Can I download and use Mountain Lion without Lion downloaded first
Can i download and use Mountain Lion if I haven't downloaded Lion yet?
Welcome to the Apple Support Communities
You can upgrade to OS X Mountain Lion from Mac OS X Snow Leopard or OS X Lion, so you can install Mountain Lion without having OS X Lion.
Just open App Store and purchase OS X Mountain Lion. If you aren't using Mac OS X Snow Leopard, you have to buy it. Don't forget to make a backup with Time Machine and/or Carbon Copy Cloner before upgrading to OS X Mountain Lion. Also, check if your apps are supported > http://www.roaringapps.com -
