I just installed Mountain Lion on my iMac that was previously running Snow Leopard. Bugt I found that some key applications no longer work, so I would like to go back to snow Leopard. I can't use time machine backups for this. what can I do?

I just installed Mountain Lion on my iMac. But In was dismayed to find that my Canon scanner software (Canoscan LIDE500F)no longer works. Nor do any of my MS offce applications. I tried to use time machine to reinstall Snow Leopard (my previous operating system), but unfortunately my time machine backups did not include system software. Also, the original system install disk that came with my iMac would not allow me to install Snow Leopard in place of Mountain Lion. I would appreciate it if somebody could tell me how to solve this problem.

The reason your Office doesn't work is because it is PowerPC code. If you will upgrade the 2004 Office to 2011 Office then that will work.
I don't understand how you managed to get your Time Machine backup to not backup the system.
Now if you still what to downgrade you will have to erase the disk and reinstall Snow Leopard. Most likely all of your application and then restore your data from Time Machine.
To me it sounds like it would be easier to upgrade your software and stay with Mountain Lion instead.

I installed Mountain Lion on my iMac. Now I cannot access the Internet. All the other computers and tablets have no problem. I did PRAM and MC reset, modem reset, etc., all the usual ju-ju. I also cannot connect on my local network to any other computer.

Yet Network control panel says I am connect to the modem, and Network Diagnosis says I am connected to the Internet. It's like the blind man who has eyes that cannot see. BTW, I am not some newbee. I have been a Machead since the early nineties and set up a half dozen networks, including the one I am using at home to which the iMac mysteriously is there but not. This has me stumped! I am considering going back to 10.7!

Can I install mountain lion on my Imac

I have a late model 2006 Imac with 4gb of RAM, I would like to install mountain lion, is this possible.

No.

After installing Mountain Lion on my Imac, volume keys and scroll function are disabled.

I just installed Mountain Lion on my 2 year old Imac and now the keyboard volume controls don't work and the scroll function on my magic mouse has stopped as well. All these were working fine until the install. I have seen other posts of people having the same problem but haven't seen any definite solutions yet. Really annoying "benefit" to upgrading.

For the mouse scrolling issue, check the setting in System Preferences > Accessibility > Mouse & Trackpad > Mouse options... button > check Scrolling.

HT1338 How do I re-install Mountain Lion in my iMac?

I have the latest iMac 27" that I got last December. I was wondering how I go about re-installing the IOS that is on the hard drive.

With OS X Lion or Mountain Lion, you just need OS X Recovery to reinstall OS X and do more things like restore Time Machine backups, repair drives, reset user passwords... See > http://support.apple.com/kb/HT4718
To reinstall OS X, hold Command and R keys while your Mac is starting to start in OS X Recovery, and reinstall OS X

Can i install mountain lion on my imac as well as my macbook?

I have downloaded mountain lion 10.8.2 to my macbook. Can I also put this on my imac? If so, how do I do it?

Yes you can. You need to log into the Mac App Store, on your iMac, using the EXACT same "Apple ID" that you used to download Mountain Lion to your MacBook, go to your Purchases list for that ID and download ML again for Free to the iMac.
Hope this helps

HT1148 Installed Mountain Lion - Now my IMAC hangs in a short loop (1 sec) at least once every other day.

Updated my IMAC from Lion to Mountain Lion. Processor 2.93GHz Intel Core 2 Duo, 4 Mag 1067 MHz DDR3. Now (usually when I am running two software items) my IMAC hangs up about once a day or so. It seems like a short 1 sec repeat. At that point the only way to stop it is to shut down using the main power button. Is anyone else having this problem? I never had a problem until I upgraded. I'm 99% sure it must be in the operating system. Can anyone tell me what's going on? Has Apple found this glitch in Mountain Lion and will they be coming out with a fix?

I was having a similar issue, my 27" iMac would lose the Internet connection, but not the wifi, later I'd find that the machine had restarted giving me a notice that there'd been a kernel panic. It was happening persistently after upgrading to Mountain Lion.
I used CCleaner to clear caches and now two days later I've had no problems.
I'm relieved that I didn't have to resort to more complex solutions.

After installing Mountain Lion on my iMac, calendar items disappeared.

My iPhone, iPad and MBP still have the calendar contents. The one item that still appears on the calendar is a holiday schedule I downloaded from another site a few years ago. I checked the preferences on the iMac and "Calendar" is checked for iCloud. Thanks for any help/suggestions!

Strange as it seems and without having resolved my problem, I decided to enter an appointment fo tomorrow. When I double-clicked tomorrow's date on the calendar to enter the information, like magic, the other appointments appeared.
Therefore, double-clicking a date on the calendar was the answer or it was a magnificent coincidence of timing!

Error when trying to install Mountain Lion - says hard disk is damaged :(

I downloaded and installed Mountain Lion on my iMac today - without any problems. But when I downloaded it to my Macbook pro (bought 2010) I get an error message telling me the installation cannot continue due to hard disk error My harddisk was fine before the installation, to my knowledge ...
Of course I tried disk utility (during the installation) and it tells me the disk needs to be repaired but I can´t choose "Repair disk" since it is grey (no write permissions it says). What can I do? I really need help!!!

I rarely post, however, because of a major screw up with Mountain Lion, I will. I have been using mac computers since 1987, have obviously installed and upgraded multiple OS new and upgrades and never, I mean never had a problem with any of them, until now. The install stalled with the message that the hard disk needed repair. I thought all of my data was lost, except for time machine backup, which was not as current as it should have been. Losing that data would have been a royal pain.
Went through the restore OS from Time Machine, then tried to repair the disk with apple disk repair utility. Not repairable. Why? I still don't have a clue. After reading multiple threads, decided to go ahead and buy DiskWarrior. This was a weird experienc. Loaded it onto external hard drive, hooked my MacBook Pro as Target disk. Loaded in DiskWarrior as hardware probelm. ???? Immediately went online to see what advice about this message. Looked like a massive coincidence had hit my laptop. Worked perfectly until loading Mountain Lion, the decided to have hard disk melt down. Suddenly, DiskWarrior indicated it was ready to rebuild my directory. The hardware warning was gone. A few minutes later, directory repaired. Rebooted, same problem. Can't load OS X, need to repair hard disk. Apple disk repair still unable to repair disk. Used DiskWarrior, repaired it no problem.
Deleted original OS 10.8 dmg. Rebooted and downloaded fresh copy of OS 10.8. This time install went flawlessly. Mountain Lion transferred all info flawlessly. Mid 2009 MacBook Pro running flawlessly and actually more smoothly now than in Lion.
1. I think original download was somehow corrupted and that is what screwed up the disk directory.
2. I do not know why apple Disk Utility would not repair the disk and Disk Warrior would. Expensive fix, but ultimately worthwhile. Did it mysefl and did not have to mess with "Genius" bar.
3. I will never go so long without backup again. That was a big mistake.
My advice:
1. Be sure you have smooth download of entire Mountain Lion file, if not, start over. My download was paused a couple of times.
2. If the install is messed up and you need Disk Repair, buy DiskWarrior and repair directory, it works flawlessly. If it initially says your disk has hardware problem, wait a few minutes while it finishes entire evaluation. It may well disappear like mine did, then actually repair the directories without a problem.
3. Be sure you have deleted old OS 10.8 Install file and load fresh one.
4. Install OS 10.8 and you should be OK.
5. Good luck.
Mountain Lion seems to have some problems, but many of them may be due to server overload at apple, delayed download with incorporated unrecognized code problems. If there is any delay, start over and get a smooth download.
Disk Utility is too light weight. Apple needs to beef it up. This is my biggest complaint. Apple utility should be able to fix disks. We should not have to spend $100 to fix a disk, but there you are.
Once fixed however, back to usual beautiful, flawless apple experience.

I installed Mountain Lion and now some times when I start my mac it look with a black screen and white text. I'm really worry about it, can somebody help me?

I installed Mountain Lion in my IMac and now, some times, when I start up my mac it looks with a black screen and white text. I'm really worry about it, can somebody help me?

Don't worry, this is probably just Verbose Mode. It's perfectly harmless. If you're not specifically invoking it, than it's probably down to an unwanted setting in NVRAM. See this article on resetting NVRAM if it continues to bother you.

Safari does not start after installing Mountain Lion

I installed Mountain Lion on my Imac. No problem. However after installing ML on my MacBook Safari doesn't open. I have installed ML again but still it does not work.
Help!

You haven't indicated if you have tried multiple DVD/CD's or just the one. Look under the "Apple > About This Mac > More Info.. > Disk Burning " do you see the Superdrive? If the system recognizes it but it doesn't work try a
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
The 5 second timing is important to a successful reset.

Problems with restart after installing mountain lion

Hi, I downloaded and installed mountain lion. The computer restarted but it has been hours and I still have the white screen with little circle with the lines, not rainbow. What do I do? Getting worried here.

Hej guys
I just bought a Hengedock docking station for my late 2011 mbp 13".
And i wasn't aware of this problem untill I recieved the dock.
Oubviously I was very frustrated as well as most other people - however, I found a solution.
This may not be the best solution, but it will do for me at least untill apple fixes this bug.
What I did was i downloaded an app called InsomaniaX (Do a google search and it will pop up as the first result). What it will do is, that (when activated) it will prevent your laptop from sleeping, when the lid is closed, BUT still turn off the internal monitor and keyboard light.
This will make use of vertical docking stations like the hengedock possible :-)

Error when installing Mountain Lion. I'm stuck...

I'm trying to install Mountain Lion to my iMac. After getting the instalation under way I returned to see an error. I tried to reinstall in and had no joy. I read a few things on the discussions and so have tried to repair my disk in DU - after verryify disk the repair option is greyed out. I've tried to erase my disk and start over, but I can't get it to 'unmount'. I've tried to restore from my time machine but get an error message about volume's being used. I've read the info in the little operations manual about repairing, restoring and reinstalling and tried that. Nothing.
I'm stuck.
Any ideas?
Thanks very much.

This says Snow Leopard, but it applies to Lion as well.
