I recently downgraded from Mountain Lion back to Snow Leopard and I forgot to export my bookmarks.

Unfortunately downgrading from Mountain Lion back to Snow Leopard means I need to wipe the hard drive and install everything from scratch. That takes hours, and I've already done the bulk of the work, twice actually since I forgot to back up my photos in Iphoto and had to start over from my Time Machine backup of Mountain Lion.
Anyhow, I am curious as to whether or not there is a way to retrieve my bookmarks from the Time Machine backup and get them onto my downgraded OS, or will I have to start all over again, restore my system to Mountain Lion and go through the hours it takes to get back to Snow Leopard.

You're missing the point. If you didn't make the /username/Library/ folder visible, then it's hidden on the TM backup. Getting to ii is beyond my ken. However, Pondini's TM FAQs might have info on that madness.

How do i downgrade to Mountain Lion

I upgraded to OSX Maverick but did not like it at all. please tell me how to downgrade to Mountain Lion.

I've,just,bought,a,new,Mac,with,mavericks,,but,I,don't,like,mavericks,,how,may,I ,downgrade,to,Mountain,Lion,10.8.5?

I've just bought a brand new iMac with OS X Mavericks but I dont like Mavericks and it also has problems with some apps I use, how may I downgrade to Mountain Lion 10.8.5?

You can't.
You cannot install or run an OS X version lower than what is, originally, installed on your Mac.
Your only option maybe to purchase a download code for OS X Mountain Lion here,
http://store.apple.com/us/product/D6377Z/A/os-x-mountain-lion
Purchase a high quality USB 3.0 or Thunderbolt hard drive, formatted as an OS X exetnded (journaled) drive with a GUID partition scheme and install OS X 10.8 Mountain Lion to the external drive and boot and run your new iMac from this external drive.
This is the only optioh to run an older OS X version on a new Mac.
I have a 2009 iMac that the lowest OS X version I can run from the iMac's internal hard drive is OS X 10.6.1.
I have an external drive with OS X 10.5.8 and can get my iMac to boot and run this older OS X version from the ex eternal hard drive.
Here is a good source for quality external hard drives.

Your only other option is to return your new iMac within 14 days for a full refund and look for older iMac, either new or used that came with OS X Mountain Lion as its original, preinstalled OS X version.
Good Luck!

Is it possible to downgrade to mountain lion with the help of a time machine backup after having updated to Mavericks?

Is it possible to downgrade to mountain lion with the help of a time machine backup after having updated to Mavericks?

Just to be clear, if by downgrade you mean uninstall, then the answer is technically, no.
You can't uninstall an OS. You can erase and re-install the old OS, but if you don't have a prior backup of your data, you'll lose it during the erase procedure.

I do update at Maverick, I want to do downgrade at Mountain Lion. How can I do that?

Hi I have a problem! I have a MBP 15 mid 2013, i7, 2.6 GHz and I do update at Maverick, I want to do downgrade at Mountain Lion because i think my mbp moves more slowly. How can I do that?

Not that easily. There is a very helpful user tip by ds store to assist you if you wish to do so:

I understand that Mountain Lion has never been released on disc, so that would seem to be the major problem.
Thanks in advance

If the Mac came pre-installed with Mavericks you can't downgrade. Have a look at mine and den.thed's comments here:

Thinking of upgrading to Yosemite - but want to be able to downgrade to mountain lion - How?

Thinking of upgrading to Yosemite - but want to be able to downgrade to mountain lion - How?
Hi all.
I am wondering if I upgrade to Yosemite is there a way that I will be able to downgrade / revert back to mountain lion if I find out that too many of my most essential applications are no longer working?
I have read there have been compatibility issues between some of my most necessary / favourite applications I use in mountain lion and Mavericks, which is why I never upgraded to Mavericks.
However , I am noticing in the app store there are a lot of apps I am interested in which I no longer able to purchase / download because they require Yosemite, and mountain lion is out-dated.
However, if I upgrade my OS, I am afraid of incompatibility with the most important apps in my workflow though.
Thanks.

Hi Arthur thank you very much for your response.
Sorry for my late reply.
My following question is summed up in the last sentence of this post.
[is only one time machine backup possible per external backup hard drive? Or can I make separate Time Machine backups for separate purposes?]
I went ahead and installed Yosemite.
There are some things I like about Yosemite and I might trial it for a little bit longer,
but after a couple of days of trials and trying out, I've decided that I think I generally prefer mountain lion better,
and I will reinstall it , and get a disk image of Yosemite and run that as a Virtual Machine when I need it.
[^ This is what I should have done in the first place.]
Before I installed Yosemite I [stupidly] used Time machine to back up only my application folders / application support / general system files,
[I used system preferences to exclude everything else in the TM backup] so that I would not have to reinstall my applications / essential system structures.
I did not back up the rest of my files and folders / whole machine though.
I should have done this.
I just didn't want to wait for about 800 gb of data to transfer [impatient].
[in retrospect I should have run Yosemite through a virtual machine within Mountain Lion to see if I liked it before installing it completely].
With Yosemite installed would I be able to make a SEPARATE time machine backup of all my files / documents / media folders in Time Machine on Yosemite, and use this to re-install these on Mountain lion if I downgrade ?
Or is only one time machine backup possible per external backup hard drive ?
Thanks.

Mid 2010 Macbook Pro (7,1) - Downgrading from Mountain Lion (10.8.3) to Snow Leopard

Hi everyone!
I am looking for some help with downgrading my macbook pro from ML back down to SL. I'll start off with some information about my case:
I bought this computer mid 2010 - I believe in July, if that matters. It is a Macbook Pro 7,1 model. The computer came with two disks, one being the Snow Leopard 10.6.3 install dvd, and the other being the applications install dvd. I do still have these dvd's, sitting beside me as I type this. Just like many others, I upgraded my computer to Lion, and from there went to Mountain Lion. I have been on Mountain Lion for several months now, currently running 10.8.3. I know a lot of you out there are disappointed with this OS, and many have experienced significant adverse effects on the overall performance of their computer. That being said, I also know that a lot of you have not had these sorts of issues running the OS. As you can tell, I mysef fall into the first category, as I have not had the greatest experience with it. It just seems to tire out my computer at activity levels which, on Snow Leopard, would not be problematic. I say tire out here in that my computer will overheat, slow down, and even sometimes crash (the crashes primarily begin with the spinning rainbow wheel, attempts to quit / force quit the applications I am running, followed by complete and utter frozenness). When this happens, I have no choice but to press the power button until the computer shuts off, then I restart, occasioanlly taking multiple attempts because of kernel panics the first one or two times. Who knows why this happens...I upgraded my RAM a couple months ago from 4GB to 8GB, which has seemed to help some but not fix the problem entirely. So, I have been wanting to downgrade back to Snow Leopard.
Ok so, I have made multiple attempts at this. For starters, I can tell you that the computer simply will not boot from the Install DVD (it is the one which came with the computer, not a retail version or anything like that). Additionaly, I cannot restore the SL DMG file from the dvd, neither to my hard drive nor to a USB drive. Because of this, I ended up trying this: I downloaded the snow leopard installation files (I believe just the content of the DVD ripped from the disc) via a torrent. I then got a 16 GB USB flash drive, wiped and formatted it (Mac OS Extended (Journaled)), and copied to the USB drive the install file I downloaded. I'll also note that I have done the same thing for Mountain Lion, copying the install file from the app store to a separate 16 GB USB drive. Ok, onto the results of my attempts at downgrading:
Each time I have tried to downgrade, I have taken the following step:
1) Power down the computer
2) Insert Snow Leopard USB drive
3) Boot up the computer, holding the option/alt key
4) Selecting the Snow Leopard USB drive
     -It would successfully boot from the USB, and would bring me to the language selection window, as expected
5) After selecting English, the window gives me the option to continue with the install, or access any utilities, and I would go to Disk Utility
6) I selected the internal drive in Disk Utility (the whole drive, not the indented partition), and I went to the partition tab, partitioning the drive to have 1 partition, Mac OS Extended (Journaled), erasing the current partition
     **Note: I have not tried this, but I feel like maybe If I were to first Erase the drive, opting to zero out all data (1 pass) in the security options, then partition the drive the same way as I did in step 6, perhaps the installation would go smoothly without returning any errors...thoughts?
7) After step 6, I would return to the install os x window and begin installation of snow leopard.
     -Every time I have done this, the install has returned an error about mid-way through, and I would be prompted to restart and try installing again
8) Now having a non-booting computer, I would end up powering down, swapping out the snow leopard usb with my mountain lion usb, booting from that, partitioning the drive the same way as before, and reinstalling mountain lion
     -This beings me back to square 1. A working, booting computer on Mountain Lion...
I believe that my issues surrounding the use of my install dvd (that came with the computer) are caused by a bad optical drive. When in mountain lion, if I insert the dvd, it will read it, but it will do so very slowly. For example, after inserting the dvd and the install os x window coming up, if I select optional installs or instructions, each of these folders would open, but take a very long time to display their contents. It also is a struggle to get the disc to eject in this situation.
So, if anyone has had a similar situation and came out on top, I would truly appreciate your help!
Thanks guys,
Nick

Do I need to downgrade to Mountain Lion?

Hello,
I just upgraded to OS X Mavericks and was ready to upgrade my VMware Fusion 3 to VMware Fusion 6 when I noticed the warning that I needed to shut down VMware before upgrading. I am certain that my VMware was only suspended, not shut down. I am not sure how to proceed as I do not want to lose my data. Do I need to downgrade back to Mountain Lion in order to shut down VMware Fusion 3?
My iMac is 24 inch, early 2009
Processor 3.06 GHz Intel Core 2 Duo
Memory 8 GB 1067 MHz DDR3
I am running Time Machine with a LaCie 4big Quadra.
Thank you!

Glad to hear there's no need to downgrade because it can be daunting.
I saw you post yesterday but hesitated to post the instructions for reverting to a prior OS X just in case you posted back with a solution.
Might want to keep this user tip handy just in case > How to revert OS X back from Mavericks: Apple Support Communities

Can I downgrade from Mountain Lion from a Macbook with Mountain Lion as the pre-installed OSx?

I had to get a new Macbook during my last semester due to my 13" Macbook Pro dying on me. My new 15" Macbook Pro came with Mountain Lion on it and I am not a huge fan of it. I am wanting to revert to Lion if that is possible for my Macbook. I do have a number of back ups of my 13" Macbook with Lion on it, but I tried it before using cmnd /r and it couldn't go back to my Lion back ups. I am not sure if I just did something wrong while I was trying to use my back up or if Macbooks with ML as the pre-installed OSx just can't go backwards.
Any help would be much appreciated

you can't revert/ downgrade diffrent OS version.the option only upgrade.

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.

Downgrading to Mountain Lion

Hi
Last June I purchased this MacBook Pro with Mac OS X 10.8. Mountain Lion, which was then upgraded to 10.8.5.
On 28 Oct 2013 after the release of Mavericks, I tried to upgrade to Mavericks, which failed and my system got irresonsive.
On the advice of Apple Support, I went to the local Apple Service Provider, who restored the system with Mavericks Developer Preview Recovery Updates losing all my data.
Now, I want to revert back to Mountain Lion by downgrading from Mavericks.
If it is possible, please help me out.
Thanks.

How to downgrade from Mountain Lion back to snow leopard with Time Machine

The final straw was the horrible mouse sideways page wiggle while trying to scroll down and read safari pages. Even after turning the feature off, tech support said it will still wiggle a little. That and the HORRIBLE grey icons everywhere was enough to send me back to my beloved iMac I loved when I bought it. I'll give up the iMessage and the few new items ML gave me. But as many others said, what I got new was far less than what was taken away.
So what tech support had me do was this. Even though the apple engineers said it would not work, apple tech support had me try it and it worked for me so good luck. Engineers said that after you install mountain Lion, it messes with ALL your time machine back ups and won't revert back to snow leopard even if you select a snow leopard date back in time. That didn't happen to me. I have a 2010 27 inch iMac
This worked for me but PROCEED AT YOU OWN RISK
Export individually any email folders or photos or data you will lose between now and the date you are reverting back to.
1. Insert Snow Leopard DVD that came with computer. The install disk not the applications. Make sure time machine external drive IS connected.
2. Restart computer and when you hear The Mac chime, hold down the C key and then it will take several minutes to boot up from the DVD.
3. Select the little blue triangle to continue in English.
4. When it gets to the screen that says "continue" stop. There might be a screen or two before this one I can't remember but either way stop at the word continue.
5. Go up to the top left and find the UTILITIES pull down menu and select disk utility.
6. In the window that opens up, Select the Apple drive which should be the very top one in the window.
7. Select erase.. it should be Mac OS extended journaled
8 select erase and maybe a password. It only takes a few seconds
9 go back up to UTILITIES in upper left and then select restore from time machine or backup or whatever it says. It's the last choice.
10. Select the external time machine drive and navigate to the date you last had Snow Leopard running and that will be the date it restores to. You will lose any data between now and then but you can export your mail, export photos, and other items separately. I only stayed on ML For a few days before hating it enough to go back so I had no loss of data except a few emails.
11. Hit RESTORE. And then it will take several hours. When you restart it, it should come right back to that day you selected as if ML was just a bad thought on someone's drawing board.   If for some reason it still comes up ML, Then they said to erase HD Again (steps 1-8) and then manually drags back USER folder or individual folders with Mail, photos etc.   if this way doesn't work, have another plan printed out so that you are not stuck by this one.
Good luck. Proceed at your own risk..

The ultimate solution:
You need an USB of at least 5 GB and the Snow Leopard Install DVD.
1. make a bootable USB with Disk Utility in it:
     a. download the Mountain Lion Installer from the App Store
     b. quit the installer after download
     c. find the installer in the Applications folder
     d. option+click in it and select "Show Pakage Contents"
     e. go to Contents>SharedSupport to find there the InstallESD.dmg file and mount it by double-clicking it
     f. with the Disk Utility, restore its contents into your USB
2. boot from the USB:
     a. restart the computer and hold-down the option key while booting
     b. select the USB and boot
3. run the Disk Utility and format in ONE partition the HD of your computer
REMEMBER: BACKUP YOUR HARD DISK BEFORE DOING ALL THESE, YOUR DISK WILL BE EREASED AND DATA BECOME UNRECOVERABLE OTHERWISE
4. insert the Snow Leopard DVD and reboot from it
5. follow the on-screen instructions to install OS X 10.6
After this, you can, if you will, upgrade to Lion or stay in Snow... Good Luck!!
