So...accordingly to technical support it seems that Photoshop CC doesn't support Intel Iris Graphics... So I spent 1800$ on a retina macbook pro and I have PS which is almost unusable for some tools lag, spot healing brush on top. Is this ever possible!?

I'm sorry you got bad information from tech support.

Photoshop supports any working GPU.
But some older or lower end GPUs won't support some of the more demanding GPU features (3D, OpenCL, etc.) - so those features will be disabled or run slower on GPUs that are not up to the demands.

But most people are not seeing any serious lag with tools. You may want to check your system for other issues (other applications busy in the background, insufficient RAM for your documents, etc.).

I checked everything with the tech support 3times...no luck... And looking around the internet it seems like I'm not the only one with those performance problems! Even after having installed the so from scratch and photoshop the same issues are present!

Most of the slowdowns were solved with updates to Photoshop.
The remaining slowdowns appear to be very system specific (drivers, bad utility software, etc.).

Which tells you that the difference is something about the new machine.

Did you install any utility programs, drivers, third party plugins, or other things on the new machine that might be interfering with applications?

Yes... But of course not that the hardware isn't powerful enough. .. It is clear that it is a software problem...!
I haven't installed anything and I also tried to format the macbook... I have just freshly installed the operating system and photoshop... Same problem!
If I disable the graphic card, or put it in basic mode the lag disappear...! But then I have other issues... Like when I change the blending mode or toggle the visibility of a layer I see the new layer construct line after line "slowly"... It takes about half a second... But at least moving the image around or using some tools doesn't give lags

I contacted adobe support 3 times... They made me do a lot of things (some of those really silly), 3 different "technicians"... The latter of which told me I'm sorry iris graphics is not supported...

I have a Macbook air retina, and it's not lagging while painting until I get to HUGE brushes. And it sounds like you are hitting some sort of driver issue that is causing the slowdown/lag.
So you may need to keep the GPU in basic mode until Apple has new drivers available.

Sorry but that I know macbook AIR whit retina display has still to come out! And the actual air has a different graphic card... It doesn't have iris graphics which I'm sure it is the cause of the problem... The thing is a macbook pro retina is mostly a professional computer.... It is a shame we have to face those kind of problems
