This way all your old settings will be saved in. I would request if you can try the following steps and share your observation: Sorry to hear about the trouble you are facing with Illustrator performance that's definitely not what should be happening. Illustrator CC 2019 on Mac Pro / High Sierra / Laggy with Delay We changed acces to the fodler which Adobe uses like 'cache' and other and still the same. We restored settings for illustrator the same. High Sierra is a clean install and we even make a new user account and is still the same.
I gave acces to remote control on my computer and everything is still the same.
Yesterday I was taling with your support on chat.
I can't move it back to Sierra because I've changed disk to NVME M.2 which Sierra doeasn't support. Is much more sluggish, laggy and delay with some task like: typing, selecting or moving object take a 0,5 sec to select or move it, moving by hand tool a whole canvas is with a delay (feeling kind of high ping) or is really laggy. Hi after moving to the High Sierra or Mojave Illustrator CC 2019 23.1.1.
