I just installed the latest version of Adobe Illustrator cc 2019 and after running the app for about 2-4 hours I begin to get this error message "not enough memory (RAM)", followed by a crash! I'm running on a Mac Pro latest OS - version High Sierra (10.13.6) with quad 1866 MHz DDR3 ECC. I've never experienced this issue prior to the upgrade and I ran the last version of Illustrator on the exact same computer -- I have since added a secondary Scratch Disk (external drive - currently all I have), and the issue has yet been resolved.
Any assistance would be greatly appreciated!
Thank you,
Mark Savage
