Slow on iMac
I have just bought a new iMac Retina 5K 27-inch (2017) with i5 3,4 processor, 16 gb of Ram, Raedon Pro 570 with 4 GB.
Illustrator is very very slow... the files I have are simple vector only with no effects and simple paths. The files are local.
I have a low spec 5 year old pc laptop, the files run better on that...
