Illustrator 30.0 lagging and still lags when i install earlier versions

I’m having a similar issue, with Illustrator (+ AIRobin) eating up way too much RAM. Even without ANY documents open, Adobe Illustrator 2026 is using 6gb of RAM, AIRobin is using 5gb. That’d be WAY too much even if I had a basic illustrator file open. I got on the phone with support but they basically toed the party line and tried to tell me that it was normal for Illustrator to use 11gb when just idling in background. There is obviously a memory leak somewhere.

And yes I tried resetting preferences and all the usual steps. I’ve been using Adobe apps for over ten years; nothing drives me crazier than having a support rep tell me to reset prefs for the 100th time.

My setup:
2021 M1 Macbook Pro (32gb of RAM)
Sequoia 15.7.7
Illustrator 30.4

I have the same issue, massive lagging  with both versions  29.8.6 and 30.3 are lagging something chronic since Sunday  26th April. The software is unusable.  I dont’ know what Adobe have done but this is massive and critical and needs to be fixed asap. I cannot produce anything. I wait 5-10 seconds or more for any function to work or render a change.,

The memory leaking I=massive. I am on a newish Mac custom features plenty of memory M3 chip and 2TB. Illustrator was trying to consume 129GB and creating a huge swap file that resulted in the Mac dying. I dont think they test anything before launch. I am looking for replacement software now as I am paying for a pro plan with Adobe and what for?

terrible terrible lagging v 30.0, don't install it.

@defaultx7uiv2q46hvw oddly the lagging is affecting 30 and 29 now. When you uninstall 30.0, did you also use Adobe Cleaner too? The uninstaller did not remove corrupt settings files, which both versions 30.0 and 29 are now reading. I would uninstall both again then use Adobe Cleaner to fix common issues and removing outdated Adobe software, cleaning corrupt files, and repairing host files for Adobe server connectivity. When you see the message "Adobe Creative Cloud Cleaner Tool completed successfully," press Enter and restart your computer. 

Go back to Adobe.com or Creative Cloud and download a fresh download of Illustrator 2025, Version 29.0 (don't use the previous download of 29 or 30) as that may had corrupted preferences, and install the 29.0 Hopefully that should work. Unless version 28 (Illustrator 2024) was better for you?!
