How to go back to Mountain lion os x 10.8 again from mavericks.?

You can reinstall your system from a backup (Time Machine or "clone") or erase it completely and reinstall Mountain Lion.
OS X Mountain Lion: Erase and reinstall OS X
If your Mac shipped with Mountain Lion already installed, you can reinstall it. Otherwise, you can only reinstall Mountain Lion if you purchased it from the App Store.
You may be better off describing the problems you're experiencing, so that they can be fixed. The vast majority of Mavericks complaints are due to outdated or poorly written software or similarly incompatible system modifications, and some simple troubleshooting may reveal the cause.

How to uninstall maverick back to mountain lion?

I have instaled maverick but have found that it does not support some programs so wish to revert back to mountin lion. Is this possible and if it is can you give me a very basic explenation of how to do so.
Many thanks

Another option too for those (kind of like me) who never did the time machine.
I just restored my computer back to Mountain Lion, and she's working perfect again, as I knew she would. E-mail popping into mailbox instantly as it should and did before the update, printer working fast as it was before update, no more freezing or glitches of any kind thankfully and finally. Here is the link that is through the Apple site to direct you on how to put your system back and get rid of Maverick's, that is assuming that is what you would like to do and also includes link for those wanting to try fixing the issue if that is your preference (most of this info is for those with mountain lion and some with the previousverisoin of OS X lion).
If you want to keep Maverick's here is a good post on the apple discussion board to help you out:
https://discussions.apple.com/docs/DOC-6161
If you just want to totally get rid of it and put back what you had before, this is the short version of how to do so:
https://discussions.apple.com/docs/DOC-3353
NOTE: This particular link has a lot of info on what to do for different situations, it is a bit lengthy, yet still very helpful.

Just in case you aren't sure what it will all look like as you are doing things, this is a link to show you a few pics of what you will see as you as you are going through the process, it can be helpful for those who aren't sure what they are doing or how to do things at all:

I hope this helps someone, it was amazing for me and my system is working perfect again like it was, battery life is way better went from like 3 hours to like 5 (not on full charge by the way, after it sat for a while doing the online update which took a while so that's saying something alone, huge improvement). I plan to wait a while before attempting to reinstall Maverick's, long enough for them to fix the bugs.

How can I revert my Macbook Air back to Mountain Lion?

I got my Macbook Air for Christmas in 2012, so it's only a little over a year old. It came with Mountain Lion, and it's been fine, until I updated it to Mavericks. Well, it was alright for a little bit, until the past two days, it has frozen on me for absolutely no reason at all twice. I wasn't running a lot of programs or anything, my hard drive space was fine, my battery was fine, and I've taken good care of it (never spilt anything on it, dropped or banged it). When it froze, the keyboard and cursor didn't respond, it wouldn't go into sleep mode and the sound skipped. All I could do was hold the power button until it shut off. So I was doing research on it and I think the reason is Mavericks. So I backed up my important things onto a separate drive, and I did the restart with command+r and I erased the hard drive completely. But now the only option for installing is reinstalling Mavericks, which I don't want to do because I'll be brought back to square one. My brother has a disc for Snow Leopard, but apparently you shouldn't downgrade a computer to a system software older than the one it came with...does this mean I have to buy Mountain Lion now or something? I don't have any backups in Time Machine (which is stupid of me). My mom has a Macbook Pro with Lion, but I don't know if I can do anything with that (unless it came with a CD, which I don't think it did, and besides it's still an older version). Am I just stuck with Mavericks then? I wish I never upgraded...unless the freezing is related to something else?

Okay. What I could possibly try doing is reinstalling Mavericks, and now that my computer's hard drive is empty, try using it and seeing if it starts freezing again. For all I know, the cause may not be Mavericks, and maybe erasing the hard drive might have fixed it...but if that doesn't work, then I'll probably have to contact Apple or something about it, and see if going back to Mountain Lion fixes it, or if there's something else wrong with my computer.

Went from Mountain Lion to Yosemite on 2009 MacBook Pro. Safari now randomly shuts down; Word doesn't work properly; iPhoto will not upload pics from iPhone; EVERYTHING is horribly slow. How to I go back to Mountain Lion?

Is there a way to go back to Mountain Lion after updating to Yosemite? Yosemite has caused nothing but problems in multiple programs. Mountain Lion ran fine. Not sure why I even updated. I am NOT a computer guru so instructions I have read for the many Yosemite fixes blow my mind. Should I be taking my MacBook Pro to the Genius Bar at the nearest Apple Store (2 hours away)? I have been a Mac user and lover for many years and am SO frustrated and disappointed in all of it right now. Please advise on what a non-tech frustrated Mac user can do.

Technically, you can downgrade if you have the following:
Your computer must be elligible to run Mountain Lion. If your computer came with Mavericks or Yosemite out of the box, you can forget it.
You need an already existing Mountain Lion installer file. If you still have that somewhere, for example in your Applications folder, or anywhere else, it's usable- note that it needs to be originally downloaded with your own Apple ID and password. If you made a Mountain Lion USB installer or DVD back then that would work too. If your Time Machine back-ups go back to the days of Mountain Lion or Lion you could check your Applications folder from inside Time Machine and restore it to your computer.
To not have data loss you need a Time Machine back-up that goes back to when you were still running Mountain Lion. Please note that this will revert your data to exactly the date that you choose. If you installed Mavericks 2 months ago, you will loose 2 months worth of data.

Mavericks is slow and nothing works properly now. How do I go back to Mountain Lion?

I have an older iMac (purchased in the Spring of 2008). I've updated the operating systems as new ones have come available and even installed more memory into the machine so the upgrades would continue to work. With the latest upgrade to Mavericks I'm ready to go backwards. Mavericks stinks. Everything runs slowly, I get the "beach ball" all the time, and I'm constantly getting error messages. I'm thinking maybe I just don't have enough memory to make this work properly.
So I want to go back to Mountain Lion (which I paid for) but can't find it in my "purchased items" in the App Store and can't seem to figure it out anywhere else. I have a backup hard drive but I haven't backed up in a LONG time so I don't want to go that route. I'd rather just do it online. Can anyone help? (I'm not very tech savvy, so please keep it simple...)

You can check to see if the Mountain Lion purchase was hidden.

I installed Maverick It turns off for no reasons, makes Safari a miserable experience, and more. How can I get back to Mountain Lion?

Maverick is a mess, well up to MS at its best. i installed it over Mountain Lion on a base Air that initially came with Lion. The worst is when the screen suddenly goes blank. After a few times, i found tha tsimpy pressing the power button brought up the welcome screen which - after the password - took me back to where I was with no loss, bu tthe first time was horrible. Then WORD for MAC started behaving strangely, with normal operations simply not working - shading to copy or cut out, for instance. Click again and again, no shading - then suddenly it workds! Safari has similar issues. So too with other software downladed earlier. simply nothing works as well as all did under Mountain Lion.
So, I want to deep six Maverick and get back to Mountain Lion. I assume that if I use CONTROL R I will simply reload Maverick. Can I download Mountain Lion from the App Store and then ??? All the copying and such - a half day lost. Is there are easier way?
<Edited by Host>

It's Command-R, not Control-R. You won't lose your files or settings if you reinstall 10.9 this way. Why don't you give that a go before reverting to 10.8.

Has anybody gone back to Mountain Lion

Hi, My Mavericks is running incredibly slow. Has anyone managed to revert back to Mountain Lion successfuly, or should I just stick it out and wait for an eventual update.
Thanks

You could certainly go back to your previous OS if you want, or we could try to help you fix what's wrong. Here's a reference: How to revert OS X back from Mavericks: Apple Support Communities

Fantastic! Didn't work at first so restarted App store and tried again. This time it asked 'ignore update'. All gone!

If I install Yosemite and find that the wifi problems are too bad, can I go back to Mountain Lion?

Almost everything I do on my MacBookPro requires a steady wifi connection. I have been reading all the horror stories about the wifi problems with Yosemite. I would like to install Yosemite, but would like to be able to go back to Mountain Lion if the problems are as extreme as I have been hearing.
Details: My Mac is 3 years old (Apple Care ran out 2 days ago!). I recently upgraded from 4GB of ram to 16GB.
Router is a Linksys E4200.
I have an Iphone-4s
My husband has an older MacBook running Lion.
I connect to an Epson Artisan 835 with wifi via my router
We have no need to have the Apple devices communicate with each other.
I am currently running an appliance in Virtual Box. One reason I want to move to Yosemite is to be able to run it in VMware Fusion instead.
Thanks.

Hi there CarylLynne,
If you upgrade to Yosemite, you should be able to use the following article to revert to the previously installed OS using Time Machine, named:

Thank you for using Apple Support Communities.
Take care,
Sterling
