First of all sorry for my bad English, so I hope you can understand my question/problem.


I am using OS X 10.8.2 at the moment on a MacBook Pro with a 2.4ghz Intel Core Duo processor, and 2GB 1067 MHz DDR3 memorie.

I think this operating system is to much for my 'old' MacBook Pro. It's not working as smooth as it did with OS X 10.5.8, and the biggest problem of all is that I can't use my photoprinters anymore (Canon Selphy C510, and HiTi Photoshuttle) because there are no drivers available for OS X 10.8.


Some drivers need PowerPC support, so I am wondering if OS X 10.6 does supprt PowerPC?

Or is it better to go al the way back to OS X 10.5?


And where do I get the drivers to downgrade to 10.6 or 10.5?

I cant find them anywhere at the online apple store!


Hope you can help me!


Greetings form the Netherlands,



(I know it's stupid that I didn't knew about this problems before I upgraded my Mac...)

MacBook Pro (15-inch Late 2008), OS X Mountain Lion (10.8.2)

    PPC applications are supported in Rosetta emulation that comes with Snow Leopard.


    Downgrade Lion/Mountain 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.


    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.
