I have a 24" iMac that's about 4 years old. I've done all the software updates as they come along but I'm having issues and wonder if I should update/upgrade the whole operating system. I currently have 10.5.8 and I'm wondering where to go from here.
My mac won't open PDFs anymore from email or websites and I've tried everything to my knowledge to correct this. There's website I that I want to utilize that requires the lastest verision of JAVA and my OS 10.5.8 is too old to do a download of the latest JAVA. So I'm thinking I need to upgrade the OS to something newer?? I'm thinking my hard drive needs to be cleaned up also (re-format?)
This computer is running slower and slower lately also.
HELP!
iMac, Mac OS X (10.5.8)
