    MacBook Pro - mid 2010 - Reinstalling Snow Leopard
    I have a 2nd hand MacBook Pro with High Sierra.

    I want to go back to Snow Leopard.

    Hard drive with 2 partitions - one empty.

    Trying to boot from disk gives:-

    You can’t use this version of the application “Install Mac OS X” with this version of macOS.
    You have “Install Mac OS X” 23.1.1.

    Restarting with C key held down ends up with light grey screen with apple in centre but no menu bar with utllity options.

    Can anyone show a way of reinstalling S L? I'm quite happy to erase/reformat disk.

    You cannot install an OS which is earlier than the one with which the Mac shipped.

    So if your 2010 shipped with Lion or later, you can’t put Snow Leopard on it; but it did ship with SL, you could.

    I’m not near my Mac just now to check this out, but I’m fairly certain that mid 2010 Macs shipped with a later OS.

    Hi Ian,
    Thanks for the reply. Lion wasn't released until July 2011 so that shouldn't be the problem.

    Thanks for that info, David. I should have been giving you that, not the other way round; but as I said I'm away from my reference lists etc.

    No worries Ian. Do let me know if you can think of anything.

    What drive type is in the MBP, SSD or HDD? If it's an SSD, you will have to format the partition before you can install 10.6.

    Restart into Recovery and run Disk Utility > First Aid, on the Start up drive partition.

    Are you using a retail Snow Leopard Disk or is it the one that came with the computer? the Mid 2010 models at the earliest would have shipped with 10.6.3 and will be unable to run anything below that. The retail disks will have 10.6.0 with the expectation that you will use software update to get it up to the latest point release.

    The Apple retail Snow Leopard disk currently being sold by Apple is 10.6.3. ($19.99)

    Hard drive with 2 partitions - one empty.

    What format does the empty partition have??
    And yes, those MBPros shipped with X 10.6.3.

    Thanks for all the replies.
    HDD - Mac OSX extended
    Installation Disk is current Apple retail Snow Leopard disk. 10.6.3.
    First Aid run on both partitions.
    Erased & reformatted both partitions
    Restarted into recovery - Restore option only offers High Sierra
    Installation Disk is recognised
    Disk Utility doesn't offer a installation option

    I don't think Disk Utility is the installer. As I recall, if one boots from the CD, a menu of options shows up, one of which is to install. The Disk Utility is only needed to format the drive. So you boot from the CD, format the drive (if you want/need to) and then install the OS from the menu. Recovery will NOT install SL. SL came before recovery partitions.

    You may want to install Snow Leopard first, onto the second partition. If you do want it on the first partition, that may present issues because of the Recovery partition.

    Thanks again.

    My problem all started with trying to install Snow Leopard on a 2nd partition and getting :-

    "You can’t use this version of the application “Install Mac OS X” with this version of macOS.
    You have “Install Mac OS X” 23.1.1."

    Since this Macbook originally came with Snow Leopard 10.6.3 (which I have ) and all other things are OK, I wondered if anyone knew how why this was happening and how to get around this.

    You have to BOOT from the install CD, not boot from anything on the internal drive. Even the Recovery partition will be newer than the installer and will result in being blocked. If you BOOT from the install CD, then the version on the CD will be the old version and the installer will be able to complete.

    If you put the install disc in and hold either "C" or "option", you should be able to install from the Snow Leopard disc.
