Photoshop CS runs using Apple Rosetta application to emulate a PPC Macintosh. Because Photoshop CS is not a Universal Binary, you may experience performance issues on an Intel-based Mac. In addition, the newer your operating system the more issues with older software you may encounter.
The upgrade part of Buko's post refers to the fact that if you do not upgrade Photoshop CS, you will not be eligible for future Photoshop upgrades.
That being posted, Have you tired anything at all in terms of system maintenance to improve performance?
All I've tried is reloading the software. Since this is the version on CS1 do I have to purchase the latest version of Photoshop. It was working on my old PowerMac and I see now it became a problem when I purchased the Intel Mac. For that matter even Quark has a tendency to crash. So far Illustrator has been fine.
Not a reply but a question. I sthere any point to upgrading Elements. My elements 8 Organizer is a disasterand I see the same from others. If I get whatever...Elements 10. will it solve the problem or same old same old ?
