How does one revert to Mountain Lion from Mavericks?

I got a new iMac a week and a half ago. It was running Mtn Lion, with i73.5, 8gb ram. I upped the memory to 16gb and installed Mavericks.
Now I have some issues that others are experiencing with Photoshop: some keyboard shortcuts not working, strange cursor behavior. There are some other things, just within my computer's behavior, that I'm not sure aren't related to Mavericks, as well, but since I've never worked on a Mac before last week, I just don't know.
The problems seem to be fixed, as reported by others over in Adobe forums, by reverting to Mountain Lion, and waiting for bug fixes in Mavericks.
I am new to the Mac world so I'd appreciate some detailed advice on the best way to do that.
Thanks for your help.

You should be calling AppleCare regarding problems with a new Mac. Telephone support is free for the first 90 days of ownership.
Various Adobe apps have had problems with Mavericks. Apple can't fix Adobe's problems. Consult Adobe for support options.

How can i Revert to Mountain Lion?

Hi all, i'm running Mavericks and have no issues or complaints, but, just for an exercize and to be ready just in case; is a correct approach to format Macintosh hd and then reinstall let say Mountain Lion or Lion from a time machine backup? And eventually, in a second time, reinstall Mavericks from time machine again?
This questions may appear obvious, but i have read a quite long thread intended to revert from Mavericks back and i wander why not to use the simplest way. There are some drawbacks?
P.S. I guess that the procedure described was intended to preserve data which could be created meanwhile after a certain time of Mavericks usage. Correct?
Thanks, Gianfranco

What version of OS X was first installed on your computer from the factory? Do you have a full system Time Machine backup of your Mountain Lion installation?
Procedurally, you must repartition the drive to permit a new Recovery HD to be installed. Then install Mountain Lion. You will need an installer for Mountain Lion. If you don't have one, but Mountain Lion or Lion was pre-installed on your computer, then you can do an Internet Recovery that will install the version of OS X originally installed on the computer.
If Snow Leopard was pre-installed then simply boot from the Snow Leopard installer DVD, repartition the drive, then install Snow Leopard. From there you can install Mountain Lion if you have the Mountain Lion installer application.

Revert from Mountain Lion to 10.6.2 without losing files and applications?

I upgraded from 10.6.2 to 10.8.3 (Mountain Lion) on my iMac, but now I cannot use most of my software, nor my scanner (even with Image Capture) because they're mostly PowerPC based. I cannot afford to replace everything at this point. Can I revert to 10.6.2 without losing files and apps? How can I do it easily? And how can I save the Mountain Lion OS I downloaded so I can load it in the future without paying again?

If you have a backup, either via Time Machine or a cloning program, you can keep everything including the Mountain Lion installer. You shouldn't have to pay for the installer again because it is tied to the Apple ID you used to purchase it. Cloning programs and two backups are better and safer than one.

Reverting from Mountain Lion to Snow Leopard

Hi there!
Just had delivered a brand new Mac Pro!! Very exciting!
I'm just wondering if there is a way to revert to Snow Leopard as I'm a producer, and a lot of my software is Snow Leopard based.
I would be so grateful if you could help me out with this!
Thanks so much,
Alex

Hi. I have a early 2012 MBA and it is running Mountain Lion. I rang apple and ordered a SL Retail Disk (10.6.3) and this did not work. When i use my external DVD drive to boot up over Mountain Lion, It just shows the 2D Snow Leopard Apple logo on a white screen followed by a whole lot of nothing.... After talking with about 4 AppleCare People they gave me the verdict that it is essentially impossible to install SL because the version of OS is older than the mac. Pretty angry because i just paid $20.99 for the disk and now its virtually useless..
Sorry for the bad news but it seems it is not a good day for people who hate Lion/Mountain Lion.

Can I use time machine to revert to Mountain Lion from Maverick?

In spite of everyone saying how great Maverick is, I have poblems with slow operation, hard to use mail addresses, problems with iPhoto, etc. So I want to go back to Mountain Lion. Can I use Time Machine to restore back before Maverick was installed?

Only if you have a full backup of Mountain Lion on your Time Machine backup drive. Then you can boot to the Recovery HD that is on the Time Machine backup drive, erase your drive, then do a full Mountain Lion restore. But if you have already used Time Machine to backup your Mountain Lion system, then this won't work. You will need to erase the drive and reinstall Mountain Lion separately. Then you can restore your Home folder from the Time Machine backup.
Or you can avoid all the above by trying to fix the problems with your Mavericks system. You will need to upgrade iPhoto.
Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the
     computer and after the chime press and hold down the OPTION key until the boot manager
     screen appears. Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
     Reinstall the 10.9.3 update: OS X Mavericks 10.9.3 Update (Combo).
4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Reinstall the 10.9.3 update: OS X Mavericks 10.9.3 Update (Combo).

How do I revert to Snow Leopard from Mountain Lion? I do not have the setup disk that came with my MacBook but I do have the Snow Leopard software.

I upgraded to Mountain Lion and very much regret this move. I cannot use Parallels or Bootcamp for Windows XP which I need for some of my 'older' accessories. How do I revert from Mountain Lion back to Snow Leopard? I have the Snow Leopard software but I do not have the original setup software disk that came with the MacBook (leant to a friend and never seen again).

If you do revert to Snow Leopard, be aware of this "feature" I used with my 2009 MacBook Pro:
When it had the original OS (Leopard, I believe) I set up Bootcamp with Windows XP. I also installed Parallels and use the Bootcamp partition for Windows XP within Parallels.
I then upgraded to Snow Leopard and all was fine.
I then upgraded to Lion and still my Bootcamp partition works for Windows XP and also for Parallels.
I have not upgraded to Mountain Lion so I cannot speak to whether or not the Bootcamp paritition of Windows XP will continue to work. If you do and it works, LET US KNOW!

Is possible to re-install Mountain Lion after Mavericks issues?

My mac became vary unstable after upgrade. Tech support was helpful but there is more issues now then before. They had me safe mode to check any programs that cause boot failure, safe reair and then reinstall new operating system. Now when it boots Finder goes on a tangent. Keeps asking about do you want to quit last program. All programs that are on the Mac came from the App store. The Mac is 2012 model that ran flawless until upgrade.If I revert to Mountain Lion, will I loose anything that was install earlier? And one other thing, I Cloud wants to be involved in everthing.

To completely restore your system from a Time Machine backup boot OS X Recovery by holding the ⌘ and r keys (two fingers) while you start your Mac.
Once the Mac OS X Utilities screen appears, select Restore from Time Machine Backup.
Select the TM backup of your Mountain Lion system prior to upgrading - their backup dates and OS X versions will appear, so you will be looking for the most recent backup of your system when it was running OS X version 10.8.5.
When it completes, your Mac will restart and your previous system state will have been restored.

I have a Belkin USB N150 Wireless Adapter used since my airport card broke. It worked in mountain lion however no longer works when i updated to mavericks. Anyone have a solution to this?

Is there anyway to fix this, or is there a way to downgrade back to mountain lion?

Hello melissanelson110,
If you've backed your Mac up with Time Machine, you may be able to revert to Mountain Lion by restoring from your backup.

Is it possible to return to Mountain Lion once using Mavericks?

So I have recently updated to Mavericks on my MacBook Air, but everything has gone wrong!
I can no longer open Pages documents which I created with Pages 4.3, and when I transfer a file which I created using Page 5 to a friend, they can't open it with Pages 4.3, either!
I was wondering if there is anyway I can return to Mountain Lion after I have updated to Mavericks?
Any help is appreciated!

You can if you had a prior Time Machine backup:
http://support.apple.com/kb/PH14176
That said, I'm unsure that reverting to Mountain Lion is necessary. Your system should still have Pages 4.3 on it (in the "iWork '09" folder in /Applications) and you can still use that if you prefer it. If you manually deleted it, then going back to Mountain Lion isn't going to give you Pages 4.3 I don't think. You should still be able to run Pages 4.3 on Mavericks.
Also, to open a Pages 5.0-created document in Pages 4.3, you should be able to save it as such. It's not the default format, but you can export to it.

I am trying increase free space in my IMac, is there any need for keeping the app installing mountain lion?

Removing "install Mountain Lion" from mac OSX 10.9.4.

If you're running 10.9.4 (Mavericks) and you have no need to revert to the earlier version of OS X (Mountain Lion) you can delete it. However, you may want to make a copy of it on to an external DVD or USB stick first 'just in case'. It may save you another 5gb+ download in the future if you ever did find you wanted to revert to Mountain Lion.

Buy new computer with Yosemite and downgrade to Mountain Lion?

Is it possible to buy a new machine with Yosemite and instead somehow downgrade/revert to Mountain Lion? There's a program I like to use that is no longer updated by the developer and isn't terribly stable on the latest two releases of OS X...

No, except by running it inside a program such as VirtualBox, Parallels Desktop, or VMware Fusion.
