Downgrade Mountain Lion to Lion - Makes me crazy!

Hi there,
Just want to remove Mountain Lion and get a fresh install of Lion.
Pressed Command+R, used Disk Utility to Inizialize the disk, rebooted but I now get a logo (denied) instead the apple logo.
Tried to press ALT and I selected the boot the dvd disk where there is Lion in it but it doesn't work too!
Any guess?
It makes me crazy!
Thanks to everyone.

Not true I have ML and run X11 no problem. The confusion might be because X11 was removed from the OS install and made a separate package to download.
See https://xquartz.macosforge.org/trac/wiki/X112.7.5
X11 while included with OS X was always really maintained by a seperate group. With ML they just made the break more obvious. This actually helps because the X11 updates no longer depend on the OS X update cycle, they can issue updates and fixes for X11 when they need to/
Apple maintains technical mailing lists in additon to these boards. For X11 support see https://lists.apple.com/mailman/options/x11-users/

HT1338 Why does mountain lion make my computer run slow and my Safari too?

why does Mountain Lion make my computer run slow and my Safari too? Please help!

The problem is probably not mountain lion. It works just fine on my computer. And a few million others.
If your computer is having problems, you can try to fix it with some simple troubleshooting maneuvers.

Trying to downgrade Mountain Lion to Lion

hey team:
I've been attempting to downgrade Mountain Lion 10.8.5 to Lion for a client's Mac Pro machine and am having a hard time doing something that I've done easily in the past.
The Mac Pro came with Lion installed, but for some reason I advised my client to upgrade to Mountain Lion, thinking that Apple would improve their operating system. Since installing Mountain Lion, he's had trouble with large file transfers crashing, screen turning green / grey and then crashing, FCP 7 frame issues on playback, etc etc
I've since made a Lion install clone to USB, and my Macbook Pro laptop will boot to that when I hold the Option key.
Holding the option key on the keyboard on the Mac Pro at startup however, with the same Lion USB inserted, yields the startup tone and a black screen. No option to boot to an alternate drive. No Apple logo. Nothing.
I've also made a Mountain Lion USB install, and holding option with that inserted, yields the startup tone and a black screen. No option to boot to an alternate drive. No Apple logo. Nothing.
When I hold Command-Option-R, it will boot from the Mountain Lion USB, but not the Lion USB, even though the same workflow works fine on the laptop.
I've even tried booting to my Snow Leopard DVD; the DVD drive spins up for a while, then stops. All with a black screen. I understand though that this might be a newer machine that won't support Snow Leopard (which is ridiculous by the way -- how is this good enough Apple?)
Is there something about 10.8.5 that locks you into 10.8.5 on a MacPro tower? This machine came with Lion installed, so obviously it can run it. Why does holding Option on bootup on the MacPro no longer work? The Option-boot works on my Macbook Pro laptop, which is also running 10.8.5.
Thanks for any help and advice!

Solved my problem cloning an old Snow Leopard machine with Carbon Copy Cloner -- a great free program that saved me this time -- to an external hard drive.
Mac Pro still wouldn't Option mount the cloned drive (I'm wondering if it's a hardware problem on this tower), so I set the tower to Target Mode, attached a Firewire to my laptop, and attached the external hard disk with the cloned Snow Leopard machine also to my laptop.
After the Mac Pro tower drive appeared on my lappy as a firewire drive, I wiped it using my laptop's Disk Utility, then cloned the cloned Snow Leopard external hard drive to the Mac Pro tower hard drive.
Mac Pro started up fine -- and apparently this tower can run Snow Leopard! But I then immediately updated to Lion using the USB stick previously mentioned, which was succesful first time out. Running Software Update brought me up to the latest version of Lion 10.7.5
Thank goodness for Carbon Copy Cloner -- and that I had a laptop still running Snow Leopard in my arsenal!

How do I downgrade Mountain Lion?

To be honest, I was really excited for Mountain Lion when it came out. However, I'm more recently a bigger minecraft fan than I expected to be. Therefore, I have noticed that the Library folder (was found under User) can no longer be visible. All I want to do is uninstall some specs and textures off of minecraft, but I can't without finding the Applications Support Folder. I would greatly appreciate it if there was a simple way to do this. It is frustrating that Apple is so "exclusive" that it cannot allow for downgrading an OS without having to back up literally everything and spending hours restoring. SO, all that to say, I really would appreciate help locating these folders. Thank you!

I don't know if this will solve your problem, but you can make your library visible by using the terminal command on this link http://osxdaily.com/2011/07/22/access-user-library-folder-in-os-x-lion/. It does work with Mountain Lion.

Downgrade Mountain Lion to Snow Leopard (Keep all data?)

I have Mountain lion and I am about tired of it and I want to go back to snow leopard. I also have Time Machine but it has been awhile since my upgrade and I have changed many things that I do not want to loose.
Is there a way to downgrade to snowleopard and keep all my info as it is now? I would think restoring via time machine would restor the OS as well?

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.
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/Mountain Lion files.

How do I downgrade mountain lion back to my mac mini 2011 lion server

Hi,
Previously, my mac mini mid 2011 was installed with mac os lion server then I have purchase and upgrade to mountain lion via iTunes.
Somehow I decided to downgrade back to lion server due to use of my mac as server, unfortunately I have no idea how to downgrade with the following reasons:
1. I don't create any time machine backup before so can't use that option.
2. I have enable vault function so now the startup has hide the recovery HD icon
3. In the Recovery mode (command + R), I only see an option to download and reinstall a fresh Mountain Lion only.
4. I can't download and install Lion server from iTunes because this os was bundle with purchase of mac mini 2011 mid version.
Any comments and helps here are appreciated. Thanks.

Well, did you save a Carbon Copy Clone (http://www.bombich.com) of the Lion installation by chance? That would be the easiest to go back to and use / update. Outside of that, or having saved the original Lion installer, I know of no way to get the OS that you are after. For future referece, on a mac mini with two harddrives, I have always made a backup partition on the second drive using CCC, and schedule clone updates to that. You can't rely on TM, inmo, so something like CCC or SuperDuper is essential. Cheers,

Downgrade Mountain lion to Lion on macbook pro Core I5

Hi, I just bought a brand new macbook pro and I find Mountain Lion very bad. Incompatibilities and freeze are not usual in my mac experience. Is it possible to downgrade it to Lion ?

No. You could try fixing your system since Mountain Lion is far stabler than Lion is.
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the 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.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main 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.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion 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.
Be sure you have a minimum of 4 GBs of RAM installed and at least 10% of hard drive capacity as free space. Note that reinstalling should install the latest version of Mountain Lion, 10.8.4.
Or you can return it. If you purchased it in the last 14 days you can get your money back.

Help! I need to downgrade Mountain Lion to Snow Leopard

Hello, I know this seems to be a major issue, but i'm going to try to see if someone can help.
Here's my scenario
I have an iMac i purchased in October 2010, and i have all of the original install discs, since owning the computer i've installed Lion and then Mountain Lion
I recently purchased a brand new mac, and want to sell the iMac.
I've done this a number of times (clean installs) and didn't realize this was going to be such an ordeal. I need help!
-I have all of my files off the iMac completely and on my new computer
-I've already zeroed out the hard drive
-reinstalled Mountain Lion
so there is absolutely nothing on the computer i need...
From this point
How do i get it back to Snow Leopard? and/or Do i even have to?
Thanks, please let me know if i need to clarify anything

Clean Install of Snow Leopard
     1. Boot the computer using the Snow Leopard Installer Disc. Insert the disc into the
         optical drive and restart the computer. After the chime press and hold down the
         "C" key. Release the key when you see a small spinning gear appear below the
         dark gray Apple logo.
     2. 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.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, set the format type to Mac
         OS Extended (Journaled, if supported), then click on the Partition button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.

Downgrading mountain lion?

I installed Montain Lion and I am not satisfied.
Mainly due to be unable to print. I am in a Windows network (office); the printer is a Canon iR1025.
I had no problem running Lion.
I am considering going back to Lion. It seemed to be faster, too, among many other minor issues.
How do I uninstall Mountain Lion and go back to Lion?
Thank you

Back up your data, get out your Lion install disk, install Lion, restore your data.

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

Why does mountain lion make my macbook pro stall?

Hi Is anyone else having a problem with Mountain Lion? My Macbook Pro was very stable woth OSX 10.6. I updated recently and now the round egg timer equivalent appears regualrly, requiring me to reboot.
I thought that I had left all this behind when I moved from PC?
Any ideas for a cure anyone?
many thanks

Launch the Activity Monitor utility, set the list at the top to "All Processes", then click on the "% CPU" heading until the top CPU users are at the top of the list. Continue to work until things slow down, then see what's consuming CPU time.

Mountain Lion makes mouse erratic in Starcraft 2

Before ML it was fine playing Starcraft 2
After the upgrade, my gaming mouse (Logitech) occasionally (but still quite frequently) move erratically, like being suddenly accelerated.
I tried turning off mouse acceleration by entering some command line I found online, but it didn't help (I don't know if it didn't turn mouse acc off or it just didn't help).
By the way, the weird mouse movement only occurs during SC2, when I quit playing, it's all good. As I said, I was playing fine before ML, so it led me to believe it was ML interfering with SC2. I adjusted every possible setting in SC2, nothing does seem to hlep.
Is there anything else I can do?
For my fellow SC2 gamers, you can feel my deep pain and sorrow when I lost numerous games by my mouse going all over the place in the battles.... please help.

I have the same problem. Before ML SC2 was running fine. Both with the graphics performance and the other stuff. But now, it's impossible to play a game. In the mid game my framrate is really bad and the mouse goes all over the place. This suxx so hard. I am not sure what the problem is. Anybody who knows? My SC2 settings are all at Low at the moment.
My setup is:
MacBook Pro 17" 2.3 GHz Intel Core i7
16 Gb Ram
Vertex3 240Gb SSD
AMD Radeon HD 6750M 1024 MB

Downgrade Mountain Lion to Snow Leopar

ML is very slow. Snow leopard worked just perfect. With ML 10.8.2 it take 1m30s to open app store, 40s google earth, so on, so on...

I would like to go back to SL and have my money back. How can I do that?

Nice site!

I´m gonna check the other possible reasons.
(this is frustrating, it worked so wll with SL :/ and ML just requires 2GB, at least thats what they say)

Check with the software vendor for an update to that program. If they don't have one yet then complain to them and continue to use your older system until there is an Update for it.
