When I apply Effects > 3D > Bevel to text on my Mac, I get the spinning pizza wheel that tells me I have a long wait ahead. In fact, if I apply it just before I go to bed, it's often still processing when I wake up, and I have to shut down Illustrator and reopen it.
Is this normal? If so, is there any way to mitigate it?
Does that happen with all objects? Also with a simple square that has no stroke or effects applied?
Do you reboot the computer regularly?
I haven't had a chance to test it with anything but text yet. I don't boot reboot my computer very often.
However, I just discovered that the problem apparently isn't nearly as serious when I use my older laptop (MacBook Pro). It's weird that I have the problem mostly with a more powerful laptop running the latest OSX.
But it sounds like this isn't a common problem, right?
It will appear with complex artwork.
So if you apply the effect to text, that qualifies for possible issues. Please try simple artwork.
And: how much RAM on the machine?
Also: rebooting the computer regularly cleans RAM and also prevents other issues from happening. Personal computers other than servers were never meant to run without rebooting.
Sorry to hear about your experience. In addition to earlier responses, I'd suggest following steps given on this community post(https://community.adobe.com/t5/illustrator/resolve-slow-performance-and-unexpected-behaviors-in-illu...) & let us know if they help.
Looking forward to your response.
