you could go with 10.5 on that machine but you will certainly need to max out the RAM
We would need a little more information about this machine before we could tell you much more.
Processor speed for instance
I have an Imac with OS X, 10.4.11.
Intel Core 2 Duo
Can I upgrade to a newer version?
Would I need more memory?
Made a search, couldn't get much. I'm not too familiar with mac, more used to windows.
Any input will be greatly appreciated.
