Adobe, like most software companies, tends to focus testing on what they can afford to fix.

Apple and Adobe have worked closely together (as always with new OS releases) to test compatibility.

As for CS4, everything is good with the exception of auto-updates to Flash panels (which I guarantee youre not using) and Adobe DriveVersion Cue (which doesnt work at the moment on 10.6).

CS3 earlier havent been tested.

The auto-update part, I mean Update: No one said anything about CS3 being not supported on Snow Leopard.

The plan, however, is not to take resources away from other efforts (e.g.

Photoshop to Cocoa) in order to modify 2.5-year-old software in response to changes Apple makes in the OS foundation.

Update 2: The Photoshop team has tested PS CS3 on Snow Leopard and found no significant problems.

Is it still an issue for Flash Builder 4 I assume so, but heres to wishful thinking.

The entry mentioning Adobe Drive issues on 64bit kernels might be a tad ambiguous.

Snow Leopard boots the 32bit kernel by default and the user would have to explicitly boot into the 64bit kernel manually by depressing the 6 and 4 keys during boot.

Would Adobe Drive still work in the default 32bit Snow Leopard kernel or is Adobe just playing it safe by warding off users altogether so theres no confusion Apparently its unusable in either mode.

Its not exactly 5 releases previous is it I found that really surprising, too, and Ill try to get more info.

I think its just some corporate conservatism at work here, and Adobe doesnt want to over-promise anything.

As I say, though, Ill try to find out more.

J. Im getting the distinct impression that Adobe are now aggressively pushing CS4, to the detriment of CS3 users who feel that the benefits of CS4 are defeated by the cost of a mass upgrade.

Im sorry Adobe, but youre all beginning to feel a bit Microsoft as a brand experience.

It was one thing for Adobe not to release CS4 in 64 bit for the Mac.

I understand that recompiling the program in a different language is a major undertaking.

But now, in what can only be interpreted as an attempt to force an upgrade to a program that doesnt even take advantage of the 64 bit programming in Snow Leopard, Adobe will not even test CS3 for Snow Leopard compatibility.

Do you want Adobes (and Apples) time spent on the past or on the future Isnt the onus for compatibility on the people who ship 2.5 years after CS3 was finished J.

I can see not going back several generations in terms of compatibility, after all Adobe is in the business of selling software, but not going back one generation is ridiculous.

Look, Im speaking just for myself, but I have no desire to force anything on anyone.

I dont want anything forced on me, and I try to do unto others) But as youd imagine, there are only so many hours in the day.

Time spent testingchanging an older version to work around changes in a future OS is time not spent addressing customer requests, taking advantage of that OSs new features, etc.

We either get a blank white window or a message saying something like no reader available, please choose one and all of the choices are grayed out, including Reader.

I am moderately sure that it is some kind of Safari problem because when I really needed something, I tried Firefox and it worked.

But next time Apple insists on taking you to lunch:) you might mention it.

I dont generally look at non Adobe pdfs, so The ones I make work ok.
