You'll need a new version of Photoshop that is Intel native.
Apple dropped support for their PowerPC emulation software.
Thanks Chris. I guess what I would like to know is whether the registered version I purchased, and I currently own, has any value with regards to buying an more current version, compatible with this new MBP? That is, do I have to buy a completely new version for full price (or CC), or can I purchase some sort of an upgrade?
I hope I am managing to ask my question clearly. Before I buy a full-priced new version, I'd like to see if I can get a discount of some sort since I already own a registered version. I won't be surprised if the answer is no.
CS5 is the earliest you can have for CS6 upgrade, and CS3 is the earliest qualifier for a creative cloud discount.
