    I just got an old 2006 iMac and its running 10.4.11. I need it to run Leopard so I can run SFOTT and get Yosemite, but how do I get Leopard on it? I got 10.5.6 from Softonic and am DLing it now, but will this work and is it legal? Please help, thanks!

    Also should mention I also got a Powermac G4 running Leopard now. Could i grab leopard from that? Or just stick with a DL?

    also I could get OS X Lion on it, should I just do that? And how would I go about that?

    Please consolidate by editing your original post instead of making several more with just a single question.

    Anyway, you'd have to get ahold of either a Leopard install disc or an official Lion USB stick which can be found on eBay or Amazon (don't remember if Apple still offers it). Are you even sure that your iMac supports Lion? If it's before late 2006 it can only go up to Snow Leopard.

    Last I knew, Apple was still selling Snow Leopard. You have to call to order it.

    How far you can go depends on when your 2006 iMac was built. The early to mid 2006 (Jan - Sep 2006) iMacs max OS is 10.6.8. The late 2006 iMac (Sep 2006 - Aug 2007) max OS is 10.7.5 (Lion).

    OS 10.6 Snow Leopard is available from Apple for $19.99.

    The Lion OS can be still be purchased from Apple for $19.99.
    The system requirements for Lion is:
    - An Intel Core 2 Duo, i3, Core i5, Core i7 or Xeon processor
    - Mac OS X Snow Leopard v10.6.6 or later (v10.6.8 recommended)
    - 7 GB free hard drive space
    - 2 GB RAM

    It appears your 2006 iMac will not support OS 10.8 (Mountain Lion), 10.9 (Mavericks), or 10.10 (Yosemite).
    The minimum hardware for 10.9 and above is:
    - iMac (Mid-2007 or later)
    - MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
    - MacBook Pro (13-inch, Mid-2009 or later)
    - MacBook Pro (15-inch or 17-inch, Mid/Late 2007 or later)
    - MacBook Air (Late 2008 or later)
    - Mac mini (Early 2009 or later)
    - Mac Pro (Early 2008 or later)
    - Xserve (Early 2009)
