NewImageAdobe and Avid have reported only minor issues with their applications on Mountain Lion, in a pair of posts on their respective websites.

The main issue with Avid's software is related to the Gatekeeper security feature:

Avid is in the process of preparing code-signed versions of our applications and plug-ins that are compatible with Mountain Lion. We realize that users will temporarily wish to work with versions that are not yet signed. Unsigned software can trigger warning messages from Gatekeeper which Avid users can easily bypass, then proceed to install and run their software.

Avid does report a few small problems when using Pro Tools 10.2 and lower, including a problem with Core Audio and another regarding some commands ceasing to function.

Adobe says that there are no known issues with Adobe CS apps and Mountain Lion.

Adobe and Apple have worked closely together to test Adobe® Creative Suite® 5, 5.5 and CS6 editions and individual products for reliability, performance and user experience when installed on Intel® based systems running Mac OS X Mountain Lion (v10.8). Earlier versions of Adobe Photoshop® (CS3 and CS4) software were also tested with Mountain Lion and there are currently no known issues.

Adobe requests that users discovering problems report them to Adobe.

Exactly my thoughts. Why does Adobe always wait till the actual release instead of using the developer previews?
What makes you think they waited ? Seems to me if they can report this today, they've been testing for quite a while, which means they have been following the developer previews.

Or do you think testing is done in a few hours ?

There should be no issues. If an application works under MacOS 1.0 (not X) then it should also run fine under MacOSX10.7 what ever. Apple should not be breaking our tools. Same goes for the hardware side. The modern computer has the capability, the power, to do any necessary emulation. All old software all the way back should work on any new Apple hardware including using it on the iOS.
Not the way it works unfortunately. APIs and subsystems get deprecated and replaced with better, more robust code. Bugs get fixed and application that were written under the assumptions that these bugs exist might break on working versions of system calls or API methods/functions.

To go forward, sometimes you just have to break with the past. It's how computing works. Systems that drag around legacy code and bit rot suffer greatly from degraded performance and bloat.

I don't think you quite understand how modern computers work if you think you can just emulate old code paths indefinitely and you don't quite understand software if you think that is even something that's desired.

I can't believe this is even a serious post. Systems change, and pulling a bunch of legacy stuff into an updated operating system so that absolutely nothing breaks is ridiculous. That's how things get crazily bloated.

It's not all that often that I agree with KnightWRX, but this is one of the times when I do. In order for operating systems to progress, they can't be saddled with 10 years of legacy stuff. Every once in a while you need to update your software. Get used to it.

I'll use Snow Leopard as my work OS anyway. It is just stable and works perfectly.

If it were only so. :( A good friend watched his ProTools recording software (only two years or so old) cease to function with Lion.

So, why did he upgrade then? Audio/video professionals never upgrade until the vendor comes out with a support statement and any patches, because that software is core to that person's job.

Apple may have broken Pro Tools, but your friend broke his own computer by upgrading carelessly.

Isn't this the whole point of providing developer previews? They've had months to prepare for Mountain Lion.

Based on my experience for working for a major software company, things can ~sometimes~ change fairly drastically between each developer preview, especially when the company shipping the updates tends to never share any specific direction with where things are going. So to save time/money devs find it better to wait till after the GM ships.
