Hey guys，Enlarging or dragging the canvas is not smooth as Win,I have tried Photoshop 2017 and 2018,but this problem still here.
Could you help me please?
See if these tips will help: Optimize performance Photoshop CC
and this: Troubleshoot Photoshop graphics processor (GPU) and graphics driver issues
thanks,I've checked my preference and make sure that this graphics works, in addition ,PS 2015.5 could work perfectly except 2018,perhaps because of the Macbook's Touch Bar.
