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

How do I re-install Mountain Lion on a new hard drive (replacement)?
I have an older iMac 24" (2007) that has been up-graded to Mountain lion. I want to replace my hard drive with a bigger one (has 500Gb). How can I re-install Mountain Lion on my new drive? I have Time Machine on this machine.
Install 10.6 and 10.8 onto the new drive exactly how you did it on the old drive, except that you won't need to pay to redownload 10.8. Alternatively, if you kept a copy of the 10.8 installer, you can just rerun it.

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 on the network 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!

How do I re-install mountain lion if my macbook air is in this state?
I just now had the bright idea of restoring my mac and wiping it clean. I'm currently in the start-up process and I can't re-install mountain lion because I never bought it. I bought this macbook air from an aquaintence last year. How do I upgrade to mountain lion if my mac is like this? Is this issue really as simple as upgrading?
cschnupp wrote:
The software on the macbook was the most recent. It had already been upgraded to mountain lion by the previous owner.
Does the original owner or yourself have a Snow Leopard istall disc? I'm guessing no.
Unfortunately it looks like my situation has worsened. I'll click re-install mountain lion then continue and a message saying "to download and restore os x, your computer's eligibility will be verified with apple." I'll click continue and another message will appear saying something like "could not install to drive please contact applecare." I am no longer being asked to enter my apple id or password. I fear this is a "you have tried x amount of times so you are now locked out" situation. Thanks to both of you for responding so soon!
That I'm not sure of. If it were me I'd still buy a copy of SL as it's cheap and partition the hard drive so I have two OS on the same disc, (make the SL partiton about 25GB). You can use one to trouble shoot the other sometimes. It also means you can boot from DVD which I like. -
Can I install mountain lion on my Imac

No.

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.

How do I directly install Mountain Lion Server?
I'd like to upgrade my Lion Mac Mini Server to Mountain Lion. Currently I'd have to update it to 10.8 Client, then on the server, install the Server app. Is there anyway to consolidate those two steps into one? I'd like to directly install 10.8 Server so I could perform remote setup of the server in one step. Is that possible?
From what I understand, you would need to update the OS X Lion Server to the 10.8 Client version followed by the OS X 10.8 Server Add-on. I am not too sure if Apple is providing an unified step for this kind of procedure.

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 -
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. -
I currently have Snow Leppard on my iMac.. I bought Mountain Lion, but it wont download to my hard drive.. HELP, please..

HT1338 How long does it take Mountain Lion to download?
I purchased the upgrade about 4 hours ago and it has been supposedly "downloading" since then with no cues or prompts. How long will this take and when should I expect to have to do something to help it along? Thanks very much.
Go to sleep. When you get up in the morning it will be waiting for you to install.
Tip: Before you install quit out of the installer, then go to /Applications/ "Install OS X.app" and copy the installer off to some other media, a pocket drive, another hard drive. Then double-click the "Install OS X.app" to do the install. This is because after it's installed the installer self-destructs. So, if you have another Mac you want to install on, or for safe keeping in case you ever need it again, save it. -
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! -
I am having to many crashes on my Mountain Lion (upgraded from Snow Leopard) and want to reinstall Mountain Lion and see if this doesn't work. My Mac crashed about once or twice a week and most recently this caused my Outlook for Mac to be corrupted. Tied to rebuild DB but it is not working.
How can I fresh install Mountain Lion removing all from my HDD and recovering my data safely?Found my old Mail, so basically back to normal.
However had two crashes since I've done everything and now I am concerned that my Mac issue might be hardware related:
