Can mountain lion be downgraded to previous OS?

I have been having extreme problems with my Macbook, 13" late 2008 aluminum since I installed Mountain Lion, to the extent that it almost seems as though I am working on a PC. Can I go back in operating systems? This is not tolerable

Your MB is j-u-s-t within the range of ML compatible machines, and ML seems that bit hungrier for resources than its predecessors, so a decrease in performance can be expected, IMHO.
FWIW, I'd recommend an OS X downgrade, indeed. Would make best sense in your case, I bet. You have a backup of your previous install? A disk or downloadable version of an earlier system? Please say yes at least once...

Can Mountain Lion be installed under own ID over previous owners?

I bought a barely used Mac Book Pro Retina in November 2013. 512 GB 16 GB Ram model samsung screen made in March 2013. I called Apple and they helped me get everything over into my name except the Mountain Lion OS. The previous owners Admin. account was also deleted after I added mine.They said if I wanted to upgrade to Maverick that would be in my name. The problem is if I wanted to revert back would it accept the previous owner's or would my licensed version have to be on first? I do not plan yet to update but need to know first.
I went to Apple.com last week and purchased my own license for OS Mountain Lion. I followed the emailed instructions and downloaded into my Applications. I then backed-up my computer to an external Toshiba Canvio Slim II external drive for MAC. Easy drive to back-up.I also printed the emails and sent over to another computer for safe keeping.
I left my licensed version of Mountain Lion OS in Applications until I want to install it.
My question is do I install over the previous owner's Mountain Lion and will it then it will show up in my name only? Or do I have to reset the entire computer and erase Mountain Lion and install my Licensed Mountain Lion? The only thing I see of the previous owners is the iPhoto update won't update but that may be because mavericks now on it to do so. I deleted iMovie and Garageband but couldn't purchase in my name as I didn't have Maverick OS.
I have had no issues with downloading from iTunes or Mac App Store or anything else in my name and or updating since I had Apple help me.
I appreciate all the great feedback on this forum.
Thank you.

No, it can't. You must repartition the drive in order to install your owned version.
Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.

Can Mountain Lion and Snow Leopard share Spotlight indexes?

I have a Starup Volume with a new partition I added to install Mountain Lion on to get a feel for what Apps I will lose if/when I switch over from Snow Leopard.,
I did this yesterday and it's working fine. I can star up most of my Snow Leopard Apps, but I have to go to the Apps folder on the SL partition to do so. That's not a huge issue to me.
However, I notice that when I switch back/forth between OSX versions, Spotlight re-indexes the volumes, so it appears the invisble index file stored at the root level of the volume is not corss-compatible... or is it?
Does anyone know of a way to get both systems to read off the Spotlight Index either creates?
—David

It's not a matter of "letting" each maintain its own database, William. By default, I believe, I have no control over what gets written. In fact, if there were a way to set a preference that says, use this index named "spotlightindexSL' only [while in SL], that might solve my problem. Then when booting up in ML, it would just go after the index it last made.
My guess is that while I am in ML or SL and not the other, there are all sorts of changes to files and the system freaks and says "Oh, now look at what a mess I've made — there are all sorts of files unaccounted for. Now I have to rebuild the whole thing."
I have 2 had drives in my Mac, both 500GB. One (Working Disk) has no operating system and all my files, and the other drive is partitioned 470/30gb with SL on the 470 and ML in the 30. When I restart in either OS, the auto-start Indexing as if for the very first time, and do both hard drives (in total: 3 partitions of files, not counting the ML Restore partition).
I know it all uncoventionally — just wanted to see what my $20 new OS will cost me in software upgrades, in particular my $1800 Adobe Design Suite CS4 and a few others.

Can Mountain Lion OSX read the TinyUDF Filesystem?

In an Apple Forum post from 8 years ago a member instructed us to use Terminal to identify the video file on the TinyUDF Filesystem DVD-R, extract the file, and give access to the file on our desktop. I have tried unsuccessfully to do this in Mountain Lion. My skills in Terminal are at fault. When I am instructed to:
Mac~ zaphod$ sudo ls -l /Volumes/StorageLabs\ TinyUDF\ Volume/Password:<enter your root/admin password>
I get:
-bash: enter: No such file or directory
Any help would be appreciated. I submit the terminal commands in the previous solution:
$ mount
Mac~ zaphod$ sudo ls -l /Volumes/StorageLabs\ TinyUDF\ Volume/Password:<enter your root/admin password>
Mac:~ zaphod$ sudo cp -R /Volumes/StorageLabs\ TinyUDF\ Volume/VIDEO_TS ~/Desktop
sudo chmod -R 777 ~/Desktop/VIDEO_TS/

I have found a way to copy files from a "StorageLabs Tiny UDF Volume" DVD file in a Mac without using Terminal. I cannot speak to Mountain Lion since I am using Snow Leopard (OS 10.6.8). However I believe this will work. It requires TOAST. Here is a step-by-step:
1. With TOAST turned off, insert the disc that contains one or more TinyUDF files.
2. Make a duplicate of the file on the desktop (cmd-d). (This may take some time - 10, 15 or 20 minutes and may require your password).
3. Open TOAST; select Video and click on DVD-Video. (NOTE: When you open TOAST the original TinyUDF Volume folder will be hidden, but the duplicate will remain). Do not eject your disc until later.
4. Display the TOAST "Media Browser" (click on the small icon at the top right corner of the Toast window, just to the left of the question mark).
5. In the Media Browser, for the upper bar use the pull-down menu and select DVD. For the lower bar use the pull down menu and select "- - - - DVD-VR". Files/Titles that are on the disc will be shown. If Chapters are desired, in the lower bar select the video File/Title and Chapters of the video will be displayed.
6. Drag only one desired File/Title to the DVD-Video window and save as a Disc Image to the Desktop or other location. File will be multiplexed and then written and the saved file will show as a folder named "(name).toast". If the disc contains multiple Files/Titles repeat this step to a new DVD-Video window for each desired File/Title, creating a separate Disc Image for each File/Title.
7. To record a single File/Title on a new DVD, in TOAST select "VIDEO_TS Folders". Click on the saved Disc Image ((name).toast). A window will open and display Video_TS and Audio_TS folders.
8. Drag the Video_TS folder to the TOAST "VIDEO_TS Folders" window. If additional titles are to go on the same new disc go to step 9. Otherwise eject the original disc and insert a recordable disc. (Clicking the "Options" button will provide a preview before making a new recording). Click the red TOAST button to create a new DVD recording.
9. To put more than one File/Title on a disc, put each File/Title in new TOAST DVD-Video window and save each as a separate Disc Image. In TOAST, select "VIDEO-TS Compilation" and drag the Video-TS folder from each Disc Image into the window in the desired sequence. Eject the original disc and insert a recordable disc. Click the red TOAST button to create a new DVD recording.
I hope I haven't missed anything, but these are the steps I took to create a new DVD from my "TinyUDF" disc which contained 3 separate videos. If you find an error please reply with a correction.

HT5628 Can Mountain Lion bootcamp support Windows Vista?

Im not really for sure what version my boot camp is. I hear there is a boot camp 5, but im not for sure if its already downloaded to my computer. I have a Mac Book Pro-13inch., 8gb of memory, and its a 2.5GHz Intel Core i5. I got it this April with Mountain Lion already installed. I update it every time a new update has been released. Please respond soon because I want to play my old games on Windows through Mac. Thanks

Welcome to Apple Support Communities
You are using OS X Mountain Lion, so you are using Boot Camp 5. Boot Camp 5 only supports Windows 7 and 8, so you can't install Windows Vista in your computer. If you want to install Windows Vista, create a virtual machine, but games won't work correctly.
The other option is to buy Windows 7 and 8 and install it in Boot Camp, so you should be able to play to these games with compatibility mode

Issues with Yosemite, can I downgrade to Mavericks or Mountain Lion and downgrade Apple Apps to work with older OS X

Hi
I am having several issues with Yosemite, mainly disappearing folders (title / name) but no folder or more importantly no previews of .mov or other video files nor unable to open them. I have years of these files that I want to edit in FCP X.
I have upgraded all my Apple apps so they now work in 10.10.2, but I want to revert back to Mavericks as a second partition for video work.
Is there any way I can reinstalled an older OS and downgrade my Apple apps like FCP X and Aperture so I can open, edit and produce dvd / bluray of these files.
Thanks in advance
Matt

I bought macbook pro at cash america used and loaded with windows 7 ultimate by boot camp.My questions is it has mountain lion loaded but original ower has name with password so how can I reload so I can sign on as administrator for downloads and upgrades

I bought a 13 inch macbook pro9.2 at Cash America with windows 7 Ultimate with boot camp program.
The Mac op sytem has Mountain Lion installed but the previous ower has his name and password attached to it and can only use as guest.

If you reformat the partition that contain Mountain Lion and reinstall Mountain Lion, it should not effect the Windows pratition.
Have said that I suggest you backup everything you might want to save just in case.

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 download but not install OSX Mountain Lion on Mavericks

Hi all
I would like to download but not install OSX Mountain Lion on my MBP which is currently running OSX Mavericks.
This however seems impossible. I think OSX Mavericks were already installed on my MBP and therefore it seems "impossible" to download it.
Now, why would I to do this? The answer is quite reasonable, due to certain demands related to an application portfolio I need Mountain Lion, because the portfolio is not upgraded to run on Mavericks. And, it is more reasonable to downgrade a version of OSX, rather waiting for the portfolio upgrade which can take years.
Yes, I need to downgrade my secondary MBP which also came with preinstalled Mavericks. This can be done, if I only could download but not install Moutain Lion.
It should be easy enough; download Mountain Lion, make an installer and make a bootable thumb usb stick. Then erase Mavericks and install Mountain Lion.
I have previously bought Mountain Lion so it is accessible to me in the App Store, but whenever I try to hit the Download button, I get a message saying this can't be done, since I am running Mavericks.
This bugs me, it should be obvious users needs the flexibility to swap whatever OSX version they need. It is still software.
So, how can I download but not install Mountain Lion on my newer MBP that came with preinstalled Mavericks?
I would like to see answers like:
"In order to get this to work, you first have to disable the locking mechanism in [...] " instead of "No, this is impossible to do"
Regards

Thanks for your reply Eric
Can't help wondering thought, people are ok with this?
Basically Apple are saying: "Do not attempt to install an older version of OSX which came preinstalled. If so, expect multiple failures." Really?! Has it always been so? For me it's not like I'm going to install Snow Leopard on my Late 2013 Retina MBP, but I would expect some form of backward compatibility between the previous version and it successor. Apparently this is not possible, and how is this even acceptable?
Personally, I am not going to downgrade, as if I had a choice, but I would and I expected however, the possibility to at least download the previous OSX version. What do you do if you have bought several applications, not necessarily online from App Store and buy yourself a new Mac with preinstalled Mavericks and after installing your "old" applications they fail to work properly? What do you do since downgrading apparently is not an option. So... again, what do you do?
If you don't have friends with an older Mac, you could be facing serious problems. And I'm not talking about gaming, but serious business.
I find this quite disturbing actually, and please tell me it's not so. There gotta be a way to do this?
I simply want to download the OS but I expect some registry values (like windows' registry) keeps preventing this.
It should be possible to simply download and not download and install in one operation, shouldn't it?
Regards

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.

Cannot boot into mountain lion after I have set the start volume to CD drive

Previously I need to boot from CD so I have set the start volume to CD drive by pressing command+option+P+R at the same time and change the start up volume to CD drive.
But right now, it can just start from CD but cannot boot into Mac OS (Mountain Lion) which is installed in the hard disk.
I have tried to press command+option+P+R at teh same time during bootup but seems like right now it doesn't recognize this command. I have tried pressing "X" or "option" or spacebar, etc during bootup but still it tries to boot from CD.
Anyway I can change the start volume back to my internal hard disk?
I have even disassembled my iMac and the CD drive to remove the previous CD as well. Then it still tries to boot from CD drive but now saying the device is not bootable and ask me to insert a bootup disk. I then tried to put the Mountain lion installation DVD (I previously created the installation DVD by following the DIY way from this link http://www.cultofmac.com/180925/how-to-make-a-bootable-disk-or-usb-drive-of-os-x -mountain-lion/) there in the drive but it still said the device is not bootable.
I have disassembled my iMac again to remove the mountain lion disk right now. So the CD drive is now empty. Anyway I can change the start volume back to my internal hard disk?
This is really frustrating .. Hope someone can help.
thanks!

Have you ejected the CD/DVD by holding mouse button on bootup?

Lost BCC field on change from Lion to Mountain Lion

On my upgrade from Lion to Mountain Lion, I lost the previous always visible BCC field, and I can't find a preference to reset so that it is always visible.
How do I get back the BCC field without having to do it message by message?

If you want to automatically BCC yourself, this is configurable with the Mail > Preferences > Composing panel. Check Automatically and select BCC from the adjacent pull-down menu.
When you select compose to create a new email, look for the following circled button and select BCC from the drop down menu.
