MBP No Detected Video Card In Photoshop CS4

I've installed Photoshop CS4 11.0.1 on my Macbook Pro (15", 2.8Ghz, nVidia 9600M GT), but under Preferences>Performance, the GPU Settings section is greyed out with the message: "Graphics hardware acceleration is unavailable. You will need to upgrade your video driver and possibly your video card."

I have tried re-installing Photoshop, trashing preference files etc. But the problem still exists. I can't find anything on the web about the 9600M GT or the 9400M not being recognised by Phothop CS4, so what could be causing this?

 

I don't know if this is even going to help...I searched the net and I couldn't find anything, but did you update the drivers after the install? Or after install go onto Nvidia and download the latest drivers?

I really don't know I know this is a long shot and probably a bad one...but did you check the hardware utility to see if everything is ok with the 9600M GT?

Hope you can get it fixed Budding...I'm not very useful with graphic cards and CS

 

I suppose there might be something wrong with the OS X 9600M GT drivers, but if that were the case, there should be some info about it online. I know the 9600M GT itself isn't faulty, because I ran numerous benchmark tests in Windows and all of them reported results as expected. Still, there should have been hardware support even with the 9400M (Photoshop reports none for both cards), so this is very strange indeed.

 

So you got new MBP? Congratulations!

I have similar issue with my Dell- AutoCad does not recognize my FX770,but I clearly see the difference between FX drivers and L2G hacked ones!

 

No prob's here with CS4 recognizing my 9400. So not sure what the problem is for you. Do you have any other issues with the Graphics card?
My guess is that it might be a hardware issue.
hope you figure it out

I just looked in my PS CS4 prefs and its recognizing the 9400m (haven't checked the 9600). I don't think its a driver issue.

 

Just tried Photoshop in Boot Camp - everything works fine. The GPU is detected and I have no problems enabling hardware acceleration. Really strange how it's not working in OS X. I must have got some setting wrongly set somewhere...

 

Just tried to do a little looking around to see if I could find some answers. As you mentioned there really isn't much to find. The only indication that this document gave is that it could be driver issue. Weird. This is a new machine right? So newest OS release and newest drivers?

I suppose my next step would be to reinstall OS X. It seems exceedingly strange that the drivers for BOTH gpu's would somehow be corrupted, especially since you don't seem to be having any other graphical issues. Maybe try posting on Adobe's support forums before anything else.

Also, I remember that the first time I ran PS CS4 after installing there was some dialog box that popped up in conjunction with gfx acceleration....I take it that you're not getting that either? ...and this is a (ahem) legal copy we're talking about?

 

Hmm...I just fixed it.

I thought that I'd take a look in the Plug-Ins folder I have for Photoshop, and under Plug-Ins>Extensions I discovered a plugin named "DisallowOpenGLWindows.plugin". No idea how it got there, since I'm using a clean install of Photoshop. Anyway, deleting that plugin fixed the problem. Really strange...

 

What a ridiculously crap plug-in! I don't have it in my Extensions folder. Very odd, but glad it works now.
