I'm running the most recent version of 10.4 (whatever that is) and I want to upgrade to Snow Leopard. If I purchase the Snow Leopard install disc can I upgrade directly to Snow Leopard from 10.4?

 

Thanks.

    Yes, if it's a retail DVD and your Mac is compatible with it.

    My Mac is a Mac Mini

     

    Macmini2,1

    Intel Core 2 Duo

    2 GHz

    2GB memory

    Bus speed 667 MHz

     

    1. How can I find out if it can be upgraded to Snow Leopard?

     

    Thanks.

    It can; 10.6 requires an Intel Mac with at least 1GB RAM.

    1. Any idea if it will run slower if I do this upgrade?

    2. Any idea if I can upgrade this Mac to 10.7?

     

    Thanks.

    When you have installed Snow Leopard, run Software Update to download and install the latest updates for Snow Leopard.

     

    To use iCloud you have to upgrade at least to Lion, but some functions are only available in Mountain Lion:

    You can also purchase the code to use to download Lion (Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM, running the latest version of Snow Leopard), or you can purchase Mountain Lion from the App Store - if you can run that:

    1. Should be OK with 2GB RAM, but more would be better of course. Expect around the same response times or maybe a little faster.

     

    2. Yes, that will run Lion, but you still need Snow Leopard to get the App Store (10.6.8). I'd recommend doubling the RAM for Lion, but it should be OK as is until you get to any intensive photo or audio stuff.

    Edit;

    << I just checked MacTracker, and it would appear that the maximum RAM you can use is 3GB; that will be slow performance in Lion >>

     

    Be warned that printer drivers, and scanner drivers in particular will almost certainly need updating for SL and probably again for Lion. That could be a problem if the printer or scanner is more than a couple of years old.

     

    Many third party applications (and some Apple ones) may need updates for SL (Adobe particularly) and definitely will for Lion, so check with the vendors for compatability before you upgrade.

     

    Also, while most legacy PPC apps that run in Tiger will also run in SL under Rosetta, they won't run at all in Lion as Rosetta support has been dropped.

     

    Lion is still only available from Phone Sales as far as I'm aware;

    in the US, call 1-800-MY-APPLE and ask for a sales assistant; they'll give you a download code to use in the Mac App Store.

    UK sales; 0800 048 0408

     

    You can't run Mountain Lion.

    If I install 10.5 on it can I then upgrade straight to Lion via USB installer from 10.5?

     

    Thanks everyone! Sorry I do not have more helpful points :-(

    You can only use the USB key by erasing the drive first as far as I know.

    If you don't already have one, you probably won't be able to get one now.

     

    10.5 will cost more than Snow Leopard - by a long way. You can't use discs from another Mac and Apple no longer stock retail discs for Leopard. In any case, it's irrelevant as you have to wipe the HD anyway, it doesn't matter what the starting OS is.

     

    Bear in mind a USB installer will cost a minimum of $80, and probably much more on Amazon or eBay, while the SL - App store route will only cost $40 total.

    You should start your own thread.

     

    If your profile is correct (G5 and 10.4.6) you can't run Snow Leopard. It requires an Intel processer (2006 on).

     

    Aside from that it's always best to disconnect all peripherals except keyboard and mouse, disconnect ethernet and turn off wifi before a major installation (I'd do it for security updates too).
