Illustrator CC 2017 Mac Extremely Slow
Per MikeGondek's advice, I am starting my own post.
I have tried Mike's suggestion for resetting my OOBE & Cloud Cache, and also dumped my preferences. None of those helped.
Opening a simple B&W Illustrator file took 00:01:42 (almost 2 minutes) with Illustrator already up and running. I added the trademark (™) symbol and closed and saved the file. Closing and saving the file took 00:0056 (almost a minute).

System stats:
iMac (21.5)
2.9 GHz Intel Core i5
16 GB 1600 MHz DDR3
NVIDIA GeForce GT 750M 1024 MB
Illustrator:
Adobe CC 2017.0.2 Release
Illustrator 21.0.2
