Mac OSX Lion is exciting new software, but before you install it there are a few things to think about: 1. You'll lose access to all your old PowerPC applications. It's been six years since Apple transitioned to Intel processors, and with the introduction of OSX Lion you will no longer be able to run PowerPC based software. Rosetta kept the old software running pretty smoothly, so you could be in for a few surprises. For starters I had to upgrade Microsoft Office. Never thought of that! 2. Closer to home, you will no longer be able to run Photojunction Retro (yes, there are still a handful of you out there). 3. There are also people still using Photoshop CS2. That won't run on PowerPC chips either. But then we've already recommended that you abandon CS2. While we're on the subject, Photojunction Remix (i.e. the current version) will also stop running on PowerPC Macs one day. Won't happen any time soon (probably twelve months away or more) but it will happen as our development environment moves to Intel-only. All in all, it may be time to think about retiring your G4s and other pre-Intel Macs. Not sure if your Mac has an Intel or PowerPC processor?
