I am using an old Power PC G4. I know people are telling me it's old and I should upgrade. Though really I am very happy with it, I have invested thousands of hours creating documents, websites, databases etc. for my business. I would like to purchase filemaker pro, though I need to have newer osx system. This is what filemaker says technical specs: Apple MacOS X 10.5.7 - PowerPC G4 - RAM 512 MB Apple MacOS X 10.6 - RAM 1 GB Microsoft Windows Vista SP2 - 1 GHz - RAM 1 GB Microsoft Windows XP SP3 - Pentium III - 700 MHz - RAM 256 MB Microsoft Windows 7 - 1 GHz - RAM 1 GB I didn't think it was possible on a power pc g4 by looks of above it is. I just need 10.6. I am currently using 10.4.11. I have 2GB of Ram, with a 1.33 GHz processor. Can I upgrade to 10.6 if so how?? Thanks for any advice. Don't really want to invest in a new machine and lots of new software. Just getting handy with my current software.
