Lion to Snow Leopard Problems

Ever since downgrading from Lion to Snow Leopard I have started experiencing problems concerning the EFI Firmware on my Early 2011 Macbook Pro. The startup bong is uncontrollable, blue screen when switching graphics cards and a change in resolution when logging out.
So I ask... Does upgrading Snow Leopard to Lion also upgrade or change the macbook pro's firmware?

OK, this is not "downgrade", this is new installation into new partition. Downgrade would mean that you started Snow Leopard and it reverts everything from Lion to Snow Leopard leaving intact all (or majority) installed applications, settings etc.

  • Since upgrading to mountain lion from snow leopard, problems!!

    I have just purchased Mountain Lion as an upgrade to snow leopard on my mac. Since updating, my screen keeps freezing when it has not been used for a while, where as before I just had to jiggle the mouse and it would wake up. Now I have to turn off the computer at the mains and switch back on again. Since mountain lion I also am having problems with flash player as it is telling me I need to upgrade - have done this several times and still no luck! Any ideas?

    Most NAS developers are slow on updating their software. Before doing an OS X update check with your NAS manufacturer to see if they support the version of OS X  you are considering. I would recommend contacting iOmega.

  • My iMac says I have 10.6.8 operating system now. Problem is I do not know if that is 'Lion' or 'Snow Leopard' ... and I wish to upgrade to 'Mountain Lion'

    My iMac says I have 10.6.8 operating system now. Problem is I do not know if that is 'Lion' or 'Snow Leopard' ... and I wish to upgrade to 'Mountain Lion'

    That is Snow Leopard.

  • Exporting OS X Mail from Mountain Lion to Snow Leopard

    After upgrading to Mountain Lion, I partitioned my iMac HD to have two partitions: Macintosh HD has Mountain Lion; I reinstalled Snow Leopard on Macintosh HD 2. Best part: you can access your user-created files from EITHER disk partition. But not so OS X Mail. I wanted to revert to Snow Leopard, since I don't like the iOS-like Mountain Lion (swipe THIS!), but Mail was a problem since all my Snow Leopard Mail was successfully migrated over to Mountain Lion during upgrade. But I think I found a way to Export Mail from ML to (a clean install of) SL.
    Try this:
    1.  Open Mail in ML. For each folder you wish to have back in SL, Export it to your ML Desktop as an .mbox file. Depending on the folder size, this can take from a few seconds to several minutes. You'll see an .mbox icon for the particular folder on your Desktop. If the word "partial" appears between the folder name and the .mbox suffix, wait a few moments for the Export to complete, at which time the word "partial" will disappear. E.g., for a folder named "Mary", if it's a huge one, the icon will first appear as "Mary.partial.mbox"; when the Export is done, you'll see "Mary.mbox".
    2.  When you've Exported all your desired folders as above, you can exit ML and re-start your Mac in SL. Open Mail in Snow Leopard, and once again, for each file you just Exported in ML to the Desktop there, select "Import Data From Apple Mail" and choose the folder from the Desktop in ML to which your mboxes were Exported. When the Import starts, you can see via a progress bar how far along it is. When done, you'll see a new folder in your SL Mail called "Import"; click on it to reveal the folder you just Imported!
    3.  Then drag the folder you just Imported out of the Import folder to "On My Mac" in SL Mail; you can then delete the Import folder.
    4.  Repeat until all your folders are where you want them (in SL).
    5.  When you have time, go back into ML and clear all those .mbox files from your Desktop.
    There MAY be an easier way, but this is what worked for me.

    The iOS view vs classic view in Mail is not the problem; I've already configured for classic view.
    Mountain Lion itself is.
    My short list (to date) of crappy Mountain Lion behavior; items marked with a double asterisk (**)represent the worst of Mountain Lion for me.
    ** No up/down arrows in scroll bar slider;
    Expose` not as easy to navigate as in Snow Leopard;
    Mail does not request passwords for either receive or send;
    No "Save Draft" icon in Mail compose window (workaround: use command-s);
    "Save As" selection missing in most app menus;
    No separate Search window in Safari (workaround: use Firefox or Opera);
    ** Can't export Mail from Mountain Lion into Snow Leopard if downgrading (I compiled this list before I stumbled on the method in this thread, but I'd prefer to effect this with Unix symbolic links);
    iWork 09 seems to have "circled the wagons" re compatibility with MS Office or LibreOffice (workaround: just use Libreoffice);

  • IMac 2011 Lion to Snow Leopard if needed?

    Hi all.
    I've posted in another discussion about my gradual move over from PC to Mac and the possibility of dual booting but this thought occurred to me. I'm now looking at getting an iMac after using a borrowed mini for a few weeks but finding that multiple monitors/keyboards etc are getting in the way. Plus I need the floorspace the PC is taking up so KVMs and the like aren't really an option.
    Anyway, I don't know where Apple are up to at the minute with their hardware/software combinations but if I were to buy a new 27" iMac tomorrow (I'm not: not THAT soon anyway) would it come with Snow Leopard and Snow Leopard installation discs? Would it have Lion preinstalled? If it DID would it come with any discs at all? I believe the recovery partition would handle that part of things (dead HDD notwithstanding) so my suspicion is that no recovery media would be included.
    Now, what if I REALLY didn't like Lion or found it had too many problems with my other hardware (I currently have a Lacie NAS drive for example!!) is there any way I could replace Lion with Snow Leopard? Would a retail boxed version, which I think is 10.6.3 have the necessary drivers or at least adequate ones to boot and run Software Update? Would the install disc that came with the MacMini work? My first thought is no it wouldn't. Am I right in thinking the installation discs that ship with a machine are model specific? Would an iMac preinstalled with Lion even be capable of downgrading (we can discuss whether Snow Leopard is a downgrade or not another time)
    Anyway, all suggestions welcome as long as they are clean.
    Edit before posting: Having said all that if the rotten AppleTV/iTunes keeps losing Home Share connection and kicking me out after 10 minutes of watching a movie then I might just stay a PC user and sell the Apple stuff that isn't working to some unsuspecting numpty. Might just go over to THAT discussion in a minute and add my voice to the ones having issues.......

    I suspect the person buying your equipment would be no more a numpty than the original purchaser. Ive been using Lion for some time now and it has frankly no more problems than any other newly introduced software/operating system.
    I went through the Windows/PC to Apple a few years ago after much deliberation (and time wasting) I am glad I did it and would not go back. Hving said that I still have a Dell XPS Laptop that is purely used to run Quicken (Windows 7) and nothing else. I could do this with Paralells or bootcamp, but at the moment I see no point. Make the jump to Apple you will probably not regret it. Your wallet might.
    My Apple TV works perfectly unless my wireless network is playing up and I suspect Apple cannot do much about that.

  • Running Lion and Snow Leopard on the same MacBook Pro

    So here's the thing .....apparently Lion won't run Photoshop and Illustrator CS2 (which I'm quite happy with and not about to shell out silly amounts of money to Adobe for even CS3) and apparently there may be (and I stress may be) problems with Word 2008 (likewise money to Microsoft for Word 2011).
    I think, and probably won't know till I've installed it, that I'd like to try Lion on my Macbook Pro but keep Snow Leopard as a separate OS to run Photoshop, Illustrator and if necessary Word until I can afford to pay Adobe (& possibly Microsoft though I can't really see what improvements they can make to Word 2008) the large amounts of money they seem to think they deserve for an upgrade.
    Does anybody out there know if it is possible to run both Lion and Snow Leopard on the same machine and if it is how do I do it?
    Thanks for taking the time to read this.

  • I upgraded to mountain lion from snow leopard, now my photo studio software is no longer supported by powerpc. Does anyone know of a fix so my photostudio will work?

    I upgraded to mountain lion from snow leopard, but now some of my applications do not work, most specifically I would like to use my photo studio, but now it tells me that powerpc is no longer supported.  Does anyone have any fixes to this problem? I would really like to continue to use software that I already have! Thank you for your help!

    PPC software will not work in Mountain Lion because there is no longer any Rosetta emulator. You will only be able to run your older software by creating another partition on your hard drive on which you can install Snow Leopard. It need not be a large partition since you can still keep your files and programs on the main partition. You could also install Snow Leopard on an external drive from which to boot the computer.
    To resize the drive do the following:
    1. 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.
    After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window.
    2. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
    3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed.  (Note: You can only make a partition smaller in order to create new free space.)
    4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
    You should now have a new volume on the drive.
    It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss.  Your drive must have sufficient contiguous free space for this process to work.
    After you create the new partition boot the computer from your Snow Leopard DVD and install Snow Leopard onto the new partition.

  • Anyone using Lion and Snow Leopard?  I will be soon.

    I will soon be using both Lion and Snow Leopard on my newly upgraded hybrid hard drive.I know that I should need to partition the drive into three 1 for Lion 1 for SL and 1 for data/applications.
    The problem is how is how much space should I give each partition?
    Has anyone done this before or have any good ideas how to go about it?
    Some extra info:
    I am currently using a MacBook Pro (mid 2009 13")
    I am currently using Lion OS X v10.7.4
    The new drive is 750GB Seagate Momentus XT 7200rpm 8GB(solid-state) hybrid drive
    The soon to be replaced drive is a stock 250GB 5400rpm HDD
    Thanks all help appreciated

    It's important that you leave a minimum amount of free space for the OS to use. You will see anywhere from 16 to 30 GBs for your OS and iLife apps. You need enough space to allow for all your third-party applications and document files. When fully set up you may have only 30 GBs of free space which is an appropriate amount to have, but not less than 20 GBs. That makes 60 GBs a reasonable minimum size.
    If you haven't put everything in concrete, I might suggest going with a 500 GB Seagate XT hybrid together with a 128 or 256 GB SSD using an OWC DataDoubler replacing the optical drive. I suggest that mainly because using the same hard drive for the OS and Data partitions will actually make file I/O slower. Having two drives and using an SSD for the startup volume will enhance file I/O operations. Only two partitions on the SSD - each 60 GBs - fit neatly in 128 GBs.

  • Please help test a gif program in Lion and Snow Leopard

    Can anyone please help me by testing a Gif creation app on a Lion and Snow Leopard machine?
    The app is called "GIFfun" and is free. It can be downloaded here:  http://www.stone.com/GIFfun/
    I have used this app for years on a Leopard machine, but needed to upgrade this week to Lion.
    Since upgrading to Lion all white areas in Gifs i create are turned to grey and its causing me problems in my workflow.
    I've purchased other Gif creation software to see if the problem was only with that app, but the grey areas are on all Gifs from all Gif creators, which makes me sure the problem lies with Lion.
    It would be a real help for me to know that other Lion users had the same problem, and to know that Snow Leopard users didn't have the problem. (as i would downgrade my OS to Snow Leopard)
    I've attached 3 images to test the app, these images need to be put into a folder and the folder dragged and dropped into the app.
    I need to know if the white areas turn grey on your OS?
    I will be really grateful if anyone can help me with this.
    Thanks

  • Best way to migrate applications from Lion to Snow Leopard?

    Hello! own a mid 2011 MacBook Pro and upgraded to Lion back when it came out. I've now realized that Lion and CIFS network drives don't get along well. I want to downgrade back to Snow Leopard. I didn't have any Time machine back ups or anything like that so I believe I have to do a fresh install, this shoudln't be a problem as I have a 6 TB FreeNAS box to back everything up to. My question is about software. Most of the software I have on my computer is free, but some of it, namely the Adobe Design Suite Standard, Quickbooks, and a few other photo/business related pieces of software have been purchased. Is there any easy way of reinstalling them? I guess what I'm asking is, how can I back up my software? Maybe a better question is how do I uninstall software in such a way so that when I reinstall it later it won't give me an error saying the serial number has already been used.

    Downgrade 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.
    You will need to reinstall your third-party software.

  • Can I have both Lion and Snow Leopard on One Hard Drive?

    My problem is I need to run a PowerPC game on Lion which Lion no longer supports. So i thought i could download Snow Leopard back to my Mac and partiition my hard drive in the process as that is the only way i know of to have both Lion and Snow Leopard. I went through the Boot Camp Asistant process and it seems it will only partition Windows 7 to my Mac when i need Snow Leopard. If anyone has any idea how to help me have both Lion and Snow Leopard at the same time on just one hard drive or figure out how to run the PowerPC programs on my Mac (if there is a way around it). The help will be well appreciated!

    How To Run Snow Leopard On A New Mac
    This does not apply to new Mac Minis or MacBook Airs. When newer models are introduced that also require Lion for hardware support, the techniques described below will no longer work with the possible exception of using Parallels 7.
    What has to be done:
    Create a new partition on the hard drive.
    Get a clone of a 10.6.8 Snow Leopard system. Put the cloned Snow Leopard system onto the new partition.
    Step One: Create a new partition on the hard drive
    To resize the drive and create a new partition do the following:
    1.    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.
           After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window.
    2.   You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
    3.    In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed.  (Note: You can only make a partition smaller in order to create new free space.)
    4.   Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
    You should now have a new volume on the drive.
    It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss.  Your drive must have sufficient contiguous free space for this process to work.
    Step Two: Obtain a clone of a Snow Leopard system:
    You will need access to a Mac already running Snow Leopard. You will need a 16 GB USB flash drive or an external hard drive to which you can clone the Snow Leopard system from the Mac that has Snow Leopard installed. Alternatives are:
    Option One:
    Install a new Snow Leopard system onto a USB flash drive. Boot the Mac used for installing with the USB flash drive. Update the flash drive system to 10.6.8 using the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard. Verify that you can boot the Mac with the USB flash drive.
    Take the USB flash drive to your new Mac and try booting from it. If it works then clone the system from the flash drive to the newly made partition:
              Clone using Restore Option of Disk Utility
    Open Disk Utility from the Utilities folder.
    Select the destination volume from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the destination volume from the left side list and drag it to the Destination entry field.
    Select the source volume from the left side list and drag it to the Source entry field.
    Double-check you got it right, then click on the Restore button.
              Destination means the new partition on the internal drive. Source means the USB flash drive.
    Option Two:
    If you have a large enough external drive you can erase and use, then it would be easier to just clone the entire Snow Leopard system from the source Mac computer to the external drive.
              Clone using Restore Option of Disk Utility
    Open Disk Utility from the Utilities folder.
    Select the destination volume from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the destination volume from the left side list and drag it to the Destination entry field.
    Select the source volume from the left side list and drag it to the Source entry field.
    Double-check you got it right, then click on the Restore button.
              Destination means the external drive. Source means the Snow Leopard Mac's internal drive.
    After cloning verify that it will boot the source Mac. If so then take the external drive to your new Mac boot with it. If all is well then restore the clone to the new partition on your new Mac:
              Restore the clone using Disk Utility
    Open Disk Utility from the Utilities folder.
    Select the destination volume from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the destination volume from the left side list and drag it to the Destination entry field.
    Select the source volume from the left side list and drag it to the Source entry field.
    Double-check you got it right, then click on the Restore button.
              Destination means the new partition on the internal drive. Source means the external drive.
    If the above seems too daunting then you might consider running Snow Leopard inside an emulator such as Parallels 7. You are permitted to install a single copy of Snow Leopard inside a virtual machine. You will need to first purchase a copy of Parallels 7 and install it on your new Mac. Create a new virtual machine configured for Mac OS X. You may then install Snow Leopard in the virtual machine then download Mac OS X 10.6.8 Update Combo v1.1 and update to 10.6.8. Be sure to include Rosetta in your initial Snow Leopard installation. Rosetta is not installed by default rather it's an optional install.

  • Home Sharing between Mountain Lion and Snow Leopard

    Hi
    I have MacBook Pro both at work and at home. The one at work has Mountain Lion with the latest version of iTune and the one at home has Snow Leopard with iTune 10.7.
    I want to share movies on my iTune account between Mountain Lion and Snow Leopard. However, it doesn't seem to work....
    How can I solve this problem?
    FYI - I am not a big fan of Mountain Lion and do NOT want to upgrade my home computer to Mountain Lion.

        I am not sure why you can't access iCloud, using a browser? Then you have the same address book, so long as you are connected to the internet.  https://www.icloud.com/
        No email involved. From the browser, you can download individual iCards or all of the individual cards, BUT unfortunately, not the Groups. So, you have to fiddle on the SL machine with keeping the groups organized.
        Up until recently, I have been able to sync Contacts from ML (which stays synced to iCloud) to SL this way:  copy the /Users/~/Library/Application Support/AddressBook/ folder from the ML computer to the SL computer by dragging the icon onto the dock's AddressBook icon, this should retain all the group info.  But, recently, this has ceased being complete.
        Apple really left us behind on this one.

  • What happens when I upgrade to mountain lion from snow leopard?

    I currently have 2 partitions. my mac side and my windows 7 home side.
    If i upgrade to mountain lion from snow leopard will i be expected to reinstall bootcamp and windows7 home along with all my other windows programs?
    What happens to the partitions? do they stay the same or does the upgrade pretty much do a factory restore and make me start from square one again?
    I have a time capsule. but do not really know how to work it like its supposed to. i just really use it to store data that i do not need on my partitions at the current times.

    I do not have any knowledge about boorcamp but on my old MacBook with snowleapard,
    I was not able to upgrade to Mountain Lion Because of my hardware I think.
    And about tha bootcamp partition:
    there shouldn't be any problem with upgrading "if even possible" because the Mac partition
    can't edit the Windows partition.
    I hope this helps you, but I would do some more research befor upgrading instead of completely trusting on my advise.
