I was planning to get one of the new macbooks pro's. As my main machine is 27 5k iMac I reckon I don't need to spend arm and leg and buy 15". 13" would be enough to do some designs on the go. So, my question is - is 13" Iris 550 gpu supported in the latest version of the suite? I mean the "GPU Performance" option and the rest?
The Iris 550 GPU is absolutely supported for InDesign GPU Performance. As a baseline, all Retina Macbook Pros are supported. You can find more info on requirements here: Adobe InDesign GPU Performance feature enhancements
Please let me know if you need any further assistance.
Is there a specific reason you're buying a Mac?
PCs are often cheaper, with a higher spec.
Just putting it out there.
