Can you change cpu's to get a higher level of osx? I'm new to mac's and this laptop was given to me and the software I want to load requires a higher level of osx than 4.11.  Is there anything physically I can do to update it?

PowerBook, iOS 4.1

10.5.8 is the latest OS that will run on a PPC Mac. You would need to purchase on the open market as Apple no longer sells this version of OS X.

But you can install up to 10.5.9

I have seen sites where a higher OS has been rigged to run on an older mac, but, from what I have read, it never works perfectly and I have never seen it for a model as old as the PowerBook.
