What kind of problems can occur when upgrading to Mountain Lion?n

Why are so many users complaining of problems after installing Mountain Lion?

Lack of preparation, often. For example, http://roaringapps.com/apps:table lists applications that do not work under ML. Especially PPC applications that require Rosetta.
Also people do not make a decent backup first, so any issues the require starting over (they will happen occasionally) require major rebuild of what they had before starting the upgrade.
Not enough free disk space causes OSX that needs 15% free to act strangely.
Many who do not bother reporting anything had no issues and are happly using ML -- like out happy friend Kappy.

Hey Luis. I not only remember…I still have mine (OS 9)! Works perfectly well…for some things; just need to be selective about what I ask it to do. (Also have its big brother Pismo running Tiger, which is still an extremely competent machine.) When I take them out of their cases, I'm still amazed at the G3's build quality.

Hard Drive warning when upgrading to Mountain Lion. 2 try and I was able to upgrade. Software update for IPhoto, had problems restarting. Do I need my hard drive checked

Hard Drive warning when upgrading to Mountain Lion. 2nd try and I was able to upgrade. Software update for IPhoto, had problems restarting. Do I need my hard drive checked

Yes.
Choose Apple menu > Restart. Hold down the Command (⌘) and R keys as your computer restarts.
When you see a white screen with an Apple logo in the middle, you can release the keys.
Click Disk Utility, and then click Continue.
In the list at the left, select the item you want to repair. (Be sure to select an item that’s indented to the right in the list, not an item at the far left.)
Click First Aid.
If Disk Utility tells you the disk is about to fail, back it up and replace it. You can’t repair it.
Click Repair Disk.
If Disk Utility reports that the disk appears to be OK or has been repaired, you’re done.
Otherwise, you may need to do one of the following steps.
If Disk Utility can’t repair your disk or it reports “The underlying task reported failure,” try to repair the disk or partition again. If that doesn’t work, back up as much of your data as possible, reformat the disk, reinstall Mac OS X, and then restore your backed-up data.
If you continue to have problems with your disk, it may be physically damaged and need to be replaced

When upgrading to mountain lion, computer froze.

When upgrading to mountain lion, computer freezed. Hearing beep from hard drive. What should I do?

After doing what a brody suggested, try an SMC reset. The article covers when this is required, but doing this will not affect anything.
Reset SMC
If the problem is still there, try booting into the Safe Mode. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application unistaller. For each disable/delete, you will need to restart if you don't do them all at once.

If I upgrade my leopard computer to snow leopard via an old update disc, can I then upgrade to Mountain Lion for the $20 deal?

If I upgrade my leopard computer to snow leopard via an old update disc, can I then upgrade to Mountain Lion for the $20 deal?

Yes, provided your computer meets the system requirements and you have updated Snow Leopard to 10.6.8:
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.
Apple - OS X Mountain Lion - Read the technical specifications.
Macs that can be upgraded to OS X Mountain Lion
iMac (Mid 2007 or newer)
MacBook (Late 2008 Aluminum, or Early 2009 or newer)
MacBook Pro (Mid/Late 2007 or newer)
MacBook Air (Late 2008 or newer)
Mac mini (Early 2009 or newer)
Mac Pro (Early 2008 or newer)
Xserve (Early 2009)

Make Your Own Mountain/Lion Installer
1. After downloading Mountain/Lion you must first save the Install Mac OS X Mountain/Lion application. After Mountain/Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Mountain/Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
3. Locate the saved Mountain/Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
4. Plug in your freshly prepared USB flash drive. You are going to clone the content of the InstallESD.dmg disc image to the flash drive as follows:
Double-click on the InstallESD.dmg file to mount it on your Desktop.
Open Disk Utility.
Select the USB flash drive from the left side list.
Click on the Restore tab in the DU main window.
Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
Drag the mounted disc icon from the Desktop into the Source entry field.
Double-check you got it right, then click on the Restore button.
When the clone is completed you have a fully bootable installer that you can use without having to re-download Mountain/Lion.
Note: The term Mountain/Lion used above means Lion or Mountain Lion.
As an alternative to the above you can try using Lion DiskMaker 2.0 that automates the process.

Can not print pdf files when upgraded to Mountain Lion?

I can see my pdf file until I go to print...then the page goes blank in review and my printer spews out blank pages. HELP! I never had this problem until I upgraded to Mountain Lion.

Let's try this:
You said;
then the page goes blank in review and my printer spews out blank pages
I'll take a guess that review should read Preview, is that correct (If it is the answer to Eric's question is Preview)

Why can't I upgrade to mountain lion from 10.6.8

I am using a Macbook 4,1 (not sure how to identify whether it's early or late 2008).
I want to upgrade to Mountain Lion, so I spent $50 getting additional memory in order to be able to upgrade. I installed the extra memory, but the app store isn't letting me download the software because it says it's not compatible with my computer. Could someone help me understand why? I don't want to have wasted $70 on the extra memory & the mountain lion software update.
Here are my specs:
Model: Macbook 4,1
Memory: 4 GB 667 MHz DDR2 SDRAM
Processor: 2.1 GHz Intel Core 2 Duo
Software: 10.6.8
Available space on hard drive: 106.72 GB
Any help would be greatly appreciated!
Thanks,
Ben

There are times when the best upgrade to run newer software is to
get a newer computer built to run it; the specifications of hardware
and software are available online as are upgrade specs.
For computer model info, Apple Support has a bit still online; for
more going back some years, see everymac.com or mactracker.ca
At this Support page, you can get some idea of what path one could
use to see what conditionally may be an OS X upgrade option...
http://www.apple.com/support/osx/upgrade/
The vintage issue and obsoletism can affect ideas on how to upgrade
since software requires a minimal level of hardware support and a
degree of higher specs than minimum in order to run more than OS X.
Snow Leopard with 4GB RAM is not a bad place to leave an older Mac.
If you should have software that is not new but still very good, it should
be able to run a few great programs. A later model MacBook Pro could
support other newer software ambitions or application needs.
Good luck & happy computing!

Problems with apps since upgrading to Mountain Lion

Since upgrading to Mountain Lion, I get the message "Application Not Responding" for several apps (Quark 9, CS5 apps, and Word for Mac) after they've been sitting open and not being used for a couple of hours. I have to "Force Quit", then restart the program. Not sure what's going on. Didn't have this problem with Lion. Any suggestions on what I can do to fix this?

OK, I updated Quark 9, CS5 apps & Word for Mac. Quark 9 and InDesign are still giving me "Application Not Responding" after being open and unused for a few hours. The other apps are now working fine...Photoshop, Illustrator, Adobe Bridge and Word for Mac. Any suggestions for what I should do about Quark and InDesign?

Is the file and apps will lost when upgrade to Mountain Lion?

I'm currently use lion and tend to upgrade to mountain lion. is it will affect my files and apps after upgrade to it? sorry, i'm a new user of apple product.

You mustn't lose your apps, but you have to do a backup if the upgrade fails and you can't access to OS. Also, you can check the app compatibility, but if you use Lion, you mustn't have problems with them

Lost use of word for mac 2004 when upgraded to mountain lion OSX

IVe just upgraded to Mountain Lion OSX and lost use of word for Mac 2004. how can i get in to work again

Office 2004 and Other Applications Don't Work in Lion/Mountain Lion
If you have Office 2004 which is a PPC-only suite, it will not work in Lion/Mountain Lion. You need to upgrade to Office 2011 - Mactopia - or you can try the freeware suite, Libre Office, that is functionally similar to Office 2007 for Windows except it works on Lion/Mountain Lion.
You may want to consider as well:
These two suites are similar to Libre Office but not as current or as well-supported:
NeoOffice
Open Office
And, then there is Apple's iWork suite:
Pages - word processing and layout
Keynote - presentation
Numbers - spreadsheet
Each can open and save Office compatible files. They may be purchased separately via the Mac App Store for $19.99 each.
As for other software, any PPC-based software will not run in Lion or Mountain Lion because Rosetta is no longer part of OS X. You will need to upgrade to Intel versions of the software.
(Access to the Mac App Store requires Snow Leopard 10.6.6 or higher and an Apple ID.)

When upgrading to mountain lion will it delete all my files?

Will an upgrade to mountain lion delete all my files so as to lose data or will my existing files be saved?

That's the difference between doing an upgrade or a fresh install. Mac OS 10.6 or .7 can be upgraded or even reinstalled over the top of the existing OS without affecting the user folder which contains all your documents, pictures, music, etc.
In order to do a fresh install you would have to used Disk Utility to wipe the drive before you do the installation.
