HT201250 New Mac w/ Mountain Lion, backup is Snow Leopard

I backed up all files from my old snow leopard OS, this notebook was stolen, My new MAC has Mountain Lion, will I be able to just select a restore point
in Time Machine or will I have to do it manually. I don't know enough to know the difference in the two OSx's.

I read that Apple has loosened their licensing restrictions on older MAC OS versions like Snow Leopard. This would allow you to run Snow Leopard on a new MAC running Mountain Lion by using a program like Fusion or Parallels to create a virtual machine. Does anyone know if this is true?
I would like to upgrade to a new MAC but can't. Some of the software that I use withthe company I work for is PPC based and there will not be updates for at least another year.
It was a common Urban Myth that Apple's Snow Leopard EULA prohibited its virtualization in Lion or Mt. Lion. This myth has been debunked over the last year or so.
Hence, Apple did not necessarily relax any "licensing restrictions" that did not exist in the first place in this regard.
As I noted to you in your other thread:

Buying a new mac with mountain lion grants free upgrade on others?

I currently have three macs running lion. I am about to purchase a new mac with mountain lion. Does the purchase allow me to download the OS in app store, which in turn would allow me to upgrade my other macs to mountain lion free of charge?

Before you buy your Mac, just check to make sure it doesn't come with Mountain Lion already installed. If it comes with Lion, then you will have to download Mountain Lion from the App Store, and then you will be able to install it on all your Macs.
I believe the same applies for iLife, if it comes pre-installed on the Mac, then you probably will not be able to download it on all your other Macs.

Why can't brand new MacBookPro9,1 (OEM Mountain-Lion) boot from Snow Leopard on external drive, or internal partition?

Why can't brand new MacBookPro9,1 (OEM Mountain-Lion) boot from Snow Leopard on external drive, or internal partition?
Is this because of hardware changes? Or firmware changes? Or is it just and Apple Inc. administrative fiat?

@Steve Holton: Sorry Steve, but you're wrong about that one . I'm using 10.8 (purchased and downloaded) on the internal HD of this MBP8,3 (2.2 GHz, 17"), and I am also able to boot into 10.7.4 and 10.6.8 from external FW800 partitions.
However, I DO have problems with my MBP9,1. It came with 10.7.4 installed and ran fine. Then I purchased and installed 10.8. It ran fine but could no longer boot from 10.7.4 on an external partition. I then reinstalled 10.7.4 on the internal HD and discovered that it is still unable to boot (even 10.7.4) from an external FW800 partition.
One of Apple's Senior Support Advisors has done some remote troubleshooting but the case is still open and unresolved. An earlier Apple Support case suggested that when, I installed the downloaded copy of 10.8, there had been a "firmware update" (behind the scenes) that is now causing the problems with booting from my external partition(s). This apparently is "a bug": it is not what is supposed to happen.
So - I believe - "the problem" really has nothing to do with hardware capability. It is strictly about Apple's strategy for "managing its future customer base". If you don't like it - use something else - I am seriously considering Ubuntu as an alternative.
If there's a hidden caveat in all this it's probably "Read Appple's Licence Agreement VERY Carefully".

How do you erase mountain lion to install snow leopard?

Hi, My mother now has a new to her late 09 mini that originally shipped with snow leopard. When she bought it it came with mountain lion preinstalled from a private seller. We were thinking that to be on the safe side that it might be better to erase and install what's on it just to be sure it is secure. I tried to erase and install snow leopard from a disk but it says that the installer is not compatible with this version of osx(mountain lion). Question: How do I erase mountain lion and install snow leopard?
I've read here that there is possibly a built in recovery disk that I can use to erase and reinstall mountain lion. Q: Is there a built in recovery disk available in my situation? and if so should I use it or be even safer by installing snow leopard instead?
Thank you,

I think I found the answer (from sl install disk use disk utility to erase then install sl). Thanks for looking.

How do I uninstall mountain lion and reinstall snow leopard

If I had known that I would not be able to use my excel files I would not have purchased OSX Mountain Lion. Is there a way to uninstall mountain lion and reinstall snow leopard?
Thank you,

To get more to the point the answer is the only way to go back to SnowLeopard is if you have a complete backup of your system from before the upgrade.
If you do you would boot off your original SL DVD wipe the disk and install SL and then restore from your SL backups.
Short of that here is no way to go back. But as the others have offered there are other less drastic means to deal with the problem.

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.

HT3910 How do I erase Mountain Lion and reinstall Snow Leopard?

Can anyone help me erase Mountain Lion and reinstall Snow Leopard. When I had installed Mountain Lion,I discovered that my music notation program, Overture was not working with Mountain Lion. Please help me, years of work is for now lost.

Back up your data files.
Use the Snow Leopard installer disc to completely erase your hard drive and everything on it.
Re-install the SL operating system, then all your applications, then your data files.
If you happened to make a bootable backup clone of your hard drive before installing Mountail Lion then you can just clone the backup back to your drive.

Is mountain lion compatible with snow leopard?

is mountain lion compatible with snow leopard? can you use the same version of iTunes

VMware and Toaster can be upgraded to versions that will run on Mountain Lion.
I was not able to find anything on PalmPilot for Mountain Lion. Of course seeing as how it is at least 15 years old that doesn't surprise me.
As I see you want to run two operating systems which means rebooting to use them just for PalmPilot. IMHO that is a lot of effort on your part for a very small gain.

Why am I getting a white screen after downloading to OSX Mountain lion from OSX Snow Leopard. What caused this?

I just upgraded to OSX Mountain Lion from OSX Snow Leopard, thinking this was the thing to do. I have NEVER had any problems with Snow Leopard, but
after just a few days after downloading OSX Mountain Lion when I turned the computer on, the screen was white. Stayed white. I had to go onto another
computer to find out what to do. What caused this and will this happen again?

Did you see a circle made of light grey hash marks in the center/bottom of the screen? My iMac is 5 years old and for every update until 10.8.2 I would get the same white screen and the first few times I paniced and thought the machine was broken! Just let it play out until the desktop comes back up and it should not do it again until you do a system update.

Need help with Mountain Lion downgrade to Snow Leopard

Recently upgraded to Mountain Lion, my daily applications do not work and i am losing patience, I need help downgrading to snow leopard, i have the snow leopard CDS that came with my mac
***detailed instructions help***
my mac specs
macbook pro 13" early 2011
My time machine
i have a backup with mountain lion, and i also have a backup from snow leopard,(my goal is to restore my latest backup from mountain lion to snow leopard)
i have backed up my files using time machine AND justcloud
My question is how, i do not want to lose any data, also is there any thing i need to be aware during this process

Downgrade Lion/Mountain Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, 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. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

Downgrading Mountain Lion back to Snow Leopard

I have a mid summer 2010 Mac Mini that originally came with Snow Leopard and I still have the install disks. In september, I upgrade to Mountain lion and due to the slow and unacceptable performance since then, I want to go back to Snow Leopard. I have been backing up on an external drive with TIme Machine for the past two years. I upgraded on September 12 and I have a several Time Machine Backups in August and early September when I was still operating with Snow Leopard. My question- Can I open up in Mountain Lion the Recovery disk option, use Disk Utility to erase the Mini's hard drive and then reinstall a time machine backup from before September 12? I have backed up files that have been changed in the past several months including mail and iweb. Will going to a previous back up in Time Machine before I upgraded work? If this won't work, can I use the Snow Leopard Disk and do the same thing- wipe clean the mini's hard drive and install a Time Machine Backup from before sept 12 from my external drive?
Any input, suggestions or instructions on this topic would be appreciated.
Thanks
Karl

Thanks mende1, excuse my ignorance but do I have the steps right?
1. Boot up with Snow Leopard Install Disk
2. Use utility to wipe clean the mini's hard drive
3. restore system using Time Machine Backup from before I upgraded to Mountain Lion
When and where will I find the option to restore from a Time Machine Backup?
Thanks

Calendars and event data lost in mountain lion upgrade from snow leopard on mac book pro

I just upgraded to mountain lion today. It appears my contacts and emails were transferred without loss to the new system but all of my calendar data and the calendars themselves have disappeared. Does anyone know how I can get my old calendars and event data back? I backed up my laptop on time machine before doing the upgrade, so my old calendars should be on my external hard drive. I'd like to simple recover the data from the laptop if it is just hidden somewhere. Alternatively, if someone could tell me how to import the backed up calendars back in that might be a good plan B. I also still have the old calendars on my iphone which I am afraid to sync for fear of data loss.
I looked through previous responses in the community to this same question and I tried deleting the account and adding it back in but that did not work. Any assistance would be appreciated. Apple support is giving me an cold shoulder that is rather unexpected given my past good experience with Apple support. Bummin out over here

Which way do you reinstall OSX?
I would go through the recovery partition, check Disk there and then run the installer. make sure you have a reliable connection the the Internet.
This could be a third party app you have running in the background that is crashing. what exactly is crashing ?
are you getting kernel Panics?
You are not able to simply roll back to Snow Leopard, you will have to have a SL disk, and then erase and install SL onto you hdd/ssd. This will erase ALL of your data so I hope you have a Time Machine backup or bootable clone.
I believe your issue is with a third party application installed.
More information is needed.
Call 1-800-My-Apple or file a dispute here https://expresslane.apple.com/Issues.action
On a personal note, I think you are missing out on ML and need to figure out if there is an application running that is causing ML to crash.
Usually a reinstall fixes my issues.

Mountain Lion using a Snow Leopard backup?

Hi,
Some applications won't run on my current OS which forces me to upgrade to Mountain Lion. When I do this I'll also erase my entire disk (it is way to full). But, before I do this I want to make sure that Mountain Lion will be able to use a Snow Leopard Time Machine backup and that I can retrieve my files (pictures, movies etc).
Thanks
Steve -

Welcome to Apple Support Communities
There are no problems doing it. Furthermore, the problem would be that you want to restore the backup made in Mountain Lion onto a computer with Snow Leopard, but in this case, you can do it without any problem.
During the initial setup, Mountain Lion will ask you to restore a backup, so follow its steps. It will ask you to restore whatever you need. See > http://pondini.org/OSX/SetupLion.html

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!!
