I currently run 10.4 on an older Intel iMac and need to upgrade to 10.6. However, I have software such as Aperture 2 and Microsoft Office that I would rather not have to replace.
Yes Aperture 2 will run fine on 10.6
You should be good with all your software .10.6 was the last OS that was fully backwards compatible with the old PPC Macs
Aperture 2.1.4 or newer and Microsoft Office are compatible with 10.6.
See this Support article: http://support.apple.com/kb/HT3604
General compatibility with 10.6 has been introduced by the 2.1.4 update, download it here: http://support.apple.com/kb/DL913
