Can I downgrade to OS X Lion?

Is there any way to downgrade the software from OS X Mountain Lion back to OS X Lion?

You have to purchase an external drive and make a backup with Carbon Copy Cleaner or Time Machine. If your MacBook is a 2010 or newer, press Command, Option and R keys on boot, open Disk Utility, erase the drive and install

  • Can I downgrade from pre-installed Lion to Snow Lepoard on Late 2011 MBP i7 2.4?

    I've purchased a MacBook Pro Quad-Core i7 2.4 with pre-installed Lion (no installation DVD's included), but, unfortunately, found out that a big number of audio software doesn't run natively and malfunctions with this version of OS, meanwhile they worked flawlessly on my previous MacBook using Snow Leopard.
    The question is: can I downgrade from pre-installed Lion to Snow Lepoard on Late 2011 MBP i7 2.4?

    Thanks a lot for your reply. I ran into those numerous techy ways of downgrading, but I've found none addressing my particular model (I think I read something about 15", while mine is 17" and sometime it does make difference - because Apple love to keep secrets about what's inside). Since i've got zellions of audio plugins install, I'm trying to make sure that messing around with systems will lead to some fruitful result. So the new question: is there a way to make sure (I haven't found any tech spec threads naming the borderline between a "working variant" and "no-use-trying" variant) - is that just a matter of chance and doing it at one own risk, or is there still a way to make surefire decision?

  • Can i downgrade my macbookpro (model indentify 11.1) to mountain lion, it comes with maveri

    can i downgrade my macbookpro with a last generation of proccessor intel (model indentify 11.1) to mountain lion, it comes with maveric. i want to do this because the software that i work can´t run in maverick

    I'm assuming that since you bought a new MBP that you don't have a copy of Mountain Lion? If not, I don't think you can find it on the app store anymore but you may be able to find a bootable disk elsewhere, ie. the apple support pages. If you have a copy of Mountain lion, then you should be in luck.
    First, if there are any files you want to save, you will want to copy the individual files to another drive so as to save them. You probably don't want to use time machine for this because not everything is backward compatible between the OS's.
    Once you obtain a bootable version of Mountain Lion, do this.
    Insert the recovery disc via USB or optical bay. (I think it may HAVE to be a USB stick, 4gb min)
    Shut down your computer. Wait for it to power down completely.
    Power on your computer while pressing and holding cmd + R.
    Once the page loads, Select Disk Utility.
    Erase the hard drive.
    Shut down computer.
    Reboot computer.
    After that, wait until progress bar is finished and then you should be able to install Mountain Lion.
    Good Luck!

  • Can't downgrade to Snow Leopard from Lion will not recognise imac dvd

    iMac 27-inch, Mid 2010  
    Software  Mac OS X Lion 10.7.4 (11E53)
    Can someone please tell me how I can downgrade from OS X Lion to Snow Leopard on my iMac
    When i insert the DVD it just spins for about 10 seconds then ejects the dvd..
    any help would be great thanks

    Lion has installed a recovery partition on your Hard Drive and you must completely erase and reformat the Hard Drive before you can go back to Snow Leopard.

  • Can new macs be downgraded to run Mountain lion

    I have a new imac can it be downgraded to run mountain lion?

    No. Mountain Lion doesn't contain the drivers needed to boot it.

  • Can I downgrade a new mac mini from 10.8 to 10.6?

    Just purchased a new Mac mini as a filemaker development platform for work. It shipped with 10.8. About half-way through getting it all set up I realized that the Filemaker 11 software I'm using has older plugins, these plugins are only compatible up to OSX 10.6. Can I downgrade this machine to 10.6?  Or can I just upgrade the plugins on this mac mini without impacting all the users of my database who have older platforms and older plugin versions?

    If you have no plans to upgrade Filemake, then I suggest you export your database to a more "universal" format such as Tab Delimited or CSV. These are text formats that almost any other database program can import. Then you can move to a new DB application compatible with Mountain Lion. Mountain Lion contains the SQL database for which there are numerous frontend GUIs.

  • How can I Downgrade to Snow Leopard and keeping all 3rd party apps?

    New to MacBookPro and really happy. With Lion...not so much. I want to downgrade to SL, however, apparently I must reformat the hard drive. Here´s the real question: If I have a backup of my entire HD with the user, docs and all the apps I have installed (on Lion), once I downgrade to Snow Leopard, can I just move all my apps from the back up disk I have made of my Lion-Running hard drive? In other words, How can I downgrade without having to reinstall every single third party app I have?

    First, how new is this Mac?  A Mac as a rule cannot boot to an older operating system version than that with which it was originally supplied.  In other words, if this is a new MBP that came with Lion then you probably cannot get it to boot to SL.
    Some applications (and I take it you do mean full "applications" rather than "apps" which are mobile device programs -- it helps to be clear o terminology) can just be dragged from place to place.  Others, notably Adobe and Office, install things all over the place and unless you are good at finding hidden files with obscure names in 10 different places you will just have to re-install them.

  • So is it just me, or is Mavericks a bust?  My MBP runs way hotter now. I don't have time for trial and error solutions. Is Apple offering a way to downgrade back to Mountain lion? I want out of Mavericks ASAP.

    So is it just me, or is Mavericks a bust?  My MBP runs much hotter since the upgrade. Why do I need ot sit around watching Activity Monitor, manually controlling my fans, and deleting extensions that I enjoy using. Don't even get me started on the Quicktime/Mov issues. I had none of these issues on Mountian Lion. Searching these forums, I see it's not just me. Why would Apple release a new system w/o peoperly testing it on MBPs?
    I don't have time for trial and error solutions. I've tried the obvious ones. No help. Is Apple offering a way to downgrade back to Mountain lion?  Or better yet, a Mavericks update that adresses these problems? As of now, I want out of Mavericks ASAP.
    My processor is 2.6 GHz Intel Core i7.
    8 GB 1600 MHZ DDR3 memory.
    13inch MBP purchased ust over a year ago- 1-13.

    Nope, it'a not just me, see above. And yup- I'm backed up, But I don't own a Mountain lion install disc. That's why I was posting here in the first place. Thanks
    Nobody owns a ML install disc - ML was only ever distributed as a download from the Mac App Store.
    If you have a Time Machine backup, you can boot into recovery mode and restore from your Moutain Lion TM backup volume.  If you have a system clone, then you can boot from the clone, and just clone ML back onto your internal drive.
    Going back to your previous installation from a backup should be trivially simply if you have the backup in hand.

  • Can a downgrade from os x mavericks 9.1?

    Hi, been using mavericks for a few months and but am slowly getting dissapointed and frustrated with how slow it is.
    I have a imac i7 with 12gb of ram and a good graphics card but nearly all my software runs too slow. It is difficult to enjoy my time on the desktop.
    My question is can i downgrade from mavericks and install Lion or something? Seriously my G4 was faster!

    Use the backup you made before you chose to upgdade and follow here
    OS X Mavericks: Revert to a previous OS X version
    although you really should troubleshoot your Mac as there is something wrong with it.All our Macs are absolutely flying under Mavericks.
    But your choice.
    Good Luck

  • Just updated my iPad 2 to OS7 and now I can't connect it to iTunes 10 on my MacBook OS 10.5.8 My MacBook can't be updated to Mountain Lion as it is early 2008 white MacBook

    Just updated my iPad 2 to OS7 and now I can't connect it to iTunes 10 on my MacBook OS 10.5.8
    My MacBook is too old and  can't be updated to Mountain Lion as it is early 2008 white MacBook.
    It all worked perfectly prior to updating the iPad 2 to OS7.
    There were no cautions or warnings
    Are there any work arounds?
    Can I uninstall OS7 and go back to OS6?
    Rediculous thing is I can connect to iTunes on an old PC of the same age

    Thanks for your comments but this doesn't help my situation at all.
    Again Apple fails to provide backward support for its own products.
    I could go to the trouble of hacking the MacBook and running Mountain Lion and iTunes 11 that way
    I think I will just move across to a PC as a result of this Apple strategy and I think I will just give up on Apples short lived product strategy.
    A laptop that lasts five years indicates a long lived product strategy.  Where they go wrong is to prevent backwards strategy when someone genuinely cannot live with ios7 like you. even the "unsupported" downgrade has now been blocked.
    Don't go windows,  you will not get five good years from a dell or an asus. If you can't buy Mountain Lion for it,  get a new macbook, enjoy.

  • How can I downgrade to Snowleopard? I need a DVD.

    Today I bought a Mac mini with Lion. How can I downgrade to Snowleopard? I need a DVD. Where can I get them?

    There is a large thread concerning this, just look for it. The final answer is as college-kid491 said, SL does not have the drivers to suppport the 2011 Mac Mini's. People who have done this have gotten very poor performance and many things not working correctly, and have had to re-install Lion.

  • Lost macros downgrading from M. to Lion

    Hi all,
    Yesterday I downgraded from Mavericks to Lion (10.7), first deleting the disk and then using time machine. It worked like a charm. Just brilliant.
    What I did realize though, is that I am missing all my macro's (for Word 11). Is there any way I can retrieve them? Are they hidden somewhere or just lost?
    Would be a great help if I could recover them, I had a lot.
    Thanks and a fine day

    Reinstalling OS X 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 OS X: Select Reinstall OS X 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.

  • How can i downgrade my iPad 1 to iOS 4?

    I see there are other posts on this where everyone responds saying to Google how.
    Well the method to do this with TinyUmbrella only works if you have saved your SHSH blobs before you upgraded. And for the record nothing about downgrading requires jailbreaking. And it's not risky to try whatsoever.
    I didn't save my SHSH blobs before only recently upgrading the iOS version, even after learning my lesson with my iPhone 3G when an update to that rendered it so slow it became an expensive paperweight.
    Now I have an iPad 1 which is a piece of hardware that will last for many years to come. I don't need another iPad what I need is for the hardware I paid for years ago as an "early adopter" to work as if bloody well should do.
    IOS 5 is so laggy it's ridiculous. This I beleive is done intentionally by Apple just to force people to buy more stuff they don't really need. But hey, that's progress, that's what many tech companies do.
    But what I want to ask is, if SHSH blobs can be faked?
    Surely a developer knows what data is required from the iPad to create SHSH blobs. Since they're unique to each device surely someone who knows enough about Apple firmware and software could fake them and then downgrading would be possible.
    So is there anyone here who knows if it can be done and if so how?
    If no one on here can help, could I go to an appointment with one of those "geniuses'" in an Apple store and have them do it?
    Thanks,
    Andrew

    It can be a bit annoying that we can't downgrade either iOS like going from 7 to 6 or downgrade any apps, specially if the update app you downloaded is not what you expected. It can be unfair and wrong. Some of us may look at either an iOS or an app, and like it, download it, then later when we do the update, we sometimes find the next version had changed too much and is not what we wanted in the first place.
    It is not easy when it comes to iOS, but when it comes to an app, you can have two options, never update if you're really happy with the current version, or update only direct to iPad but don't sync to iTunes. Try out the app and if it is not what you paid for, you can delete it from iPad as long as you have not updated the app in your iTunes library, and sync the earlier version from iTunes back to iPad.

  • I'm about to purchase Lion.  My husband and I each have a desktop, iPad and iPhone.  We currently use one Apple ID for iPad/phone purchases.  Can we purchase 2 copies of Lion with one Apple ID?

    I'm about to purchase Lion.  My husband and I each have a desktop, iPad and iPhone.  We currently use one Apple ID for iPad/phone purchases.  Can we purchase 2 copies of Lion with one Apple ID or do we have to use different Apple IDs for the purchase?  If we use the different Apple IDs can we still use the same ID for all of our purchases.

    And just in case you were wondering, installing one purchased copy on all the Macs you own is specifically called out as allowed in the Mac OS X Lion license.
    If you do not want to download multiple times, just copy the Applications -> Install Lion app to a safe place BEFORE you do the first install.  Then copy that copy to any Mac you own where you want to install Lion.
