I know there were a few threads about using US-spec Macs in Japan. But, I would like to ask about the software side of the issue, because US-spec Macs would be compatible in Japan in terms of power usage and what not. On my Macs, I have the following software I frequently use: Adobe CS2, Macromedia MX2004, Corel Paint IX, Alias SketchbookPro, Aperture, MS Office 2004, iWoks 06, and several others such as Toast, Little Snitch, and etc. I think I may get into problem with Adobe's activation in Japan should I need to reinstall CS2 and MX2004 (so I hope my Macs will stay in good shape without hardware crash). I kept Japanese as extra language when I did the clean install of OS to get rid of the junks I don't need. So, now to the question. Is there going to be issues purchasing and installing software I would purchase in Japan? Is there going to be problem with Apple's software updater in Japan? Is there anything I should watch out for? And, a few questions on one particular software, CS2: I have CS2 I bought in the states. Is there going to be some issues with activation if I need to reinstall CS2 in Japan when my Mac crashes? Also, if I make CS2 files (say, PS file, Illustrator file, or InDesign file), can those files be read by Japanese-spec CS2? I think Adobe only sells their CS2 and other software in Japanese version only in Japan.
