I have been running 10.5.8 for a long time on a 2.16ghz core 2 duo imac (imac came with 10.4 tiger from new). I have been having a few issues with internet connection and running slow recently so decided to do an archive and install. I used the 10.4 disc and cant find the 10.5 disc to upgrade it to how it was. Now i cant (or don't know how to) get all my music, photos, doc's etc back. I have all the old applications but none of my doc's. I have an external hard drive/time machine back up but it says this cant be used with 10.4. I can see the previous systems folder but i can not access it. Do i need 10.5 or is there a way of getting all my things back on my mac?
