I have the same problem. Been looking all over the internet for months for an issue. I downgraded to previous versions. Still the same problem. Adobe Sucks as a company. They just do. They have plenty of time to get their Apps working on an OS. Hell, Apple has a public F'ing beta. Then you have these arrogant adobe fanboys and admins who over-confidently give you the wrong f'ing answers because they are too full of themselves to actually read and try what people are saying... They just assume were all dumb twats. I wouldn't even be using illustrator anymore if it wasn't in use by my company. There are plenty of other solutions out there that are just as good and cost a lot less. I'm going to try turning off dictation to see if it works. It would be nice if Adobe would actually make some software that worked with Mac OS... But instead they will just blame Apple... The fact that you have disable features like "Dictation" and tweak your "Accessibility" settings to get Illustrator and Photoshop to work is beyond ridiculous. So I guess people who need these accessibility features to do their work are SOL thanks to Adobe? Adobe doesn't care about these users? POS company has gotten way too bloated just like Photoshop. I have nothing good to say about Adobe.

--------------EDIT--------

People who need these accessibility features should file a class action discrimination lawsuit against Adobe if they don't fix these issues. There is a similar issue with Photoshop but you have to tweak your accessibility settings. Turning off dictation actually worked.

"Illustrator works, you just need to disable the built-in keyboard on your MacBook Pro for it to work properly, don't complain to us, it's Apple's fault for building a new Mac Book Pro and forcing us to update our shitty, bloated, riddled with technical debt software". - Adobe's official company response backed up by all their arrogant fanboys.

Illustrator was a dead slow and doing random moments with 23.0.4 until I did what Nick de Bruyne said on OS 10.14.5 (18F132). Saved many brain cells, but lost 5 hrs of sleep.

That does not fix the slow-nesssss.

I just can't to work with the new AI on Mojave! I'm losing jobs, spending time. I have had to do a "cleaning formatting" on my iMac. Of course, didn't work.

My illustrator latest version is using more then 120 gigs of RAM. I have 32 installed.

illustrator 23 is very very slow with Mojave

Wish I'd have never upgraded to Mojave.... Crashes galore, spinning wheels, loads of lag, prgrams unresponsive, fan going mad on my Macbook Pro, Illustrator just awful! Indesign and typekit issues central! I'm not paying good money every month for this level of hassle and unproductivity! might start charging Abobe back for my wasted time. How about get a decent testing dept before releasing this rubbish!

Same problem here. Dictation is off, version is 23. Illustrator still unusable.

Hi, I have just upgraded to Mojave - using latest 23.1 version of illustrator - tried to draw with pen tool and the tool won't release.........anyone else had similar issues and how did they resolve please.....I am freelance, just lost 1/2 days work because of this......so frustrating. Adobe support have escalated it to their senior team after chatting with them all morning without any progress.

AND...disabling "Dictation" doesn't help in this situation as it was already off.

Upgraded to Mojave...Have Illustrator 23.1
All other Adobe apps work fine. Illustrator takes ages to save a file. If you look at the Force quit menu, it says Illustrator "Not responding". A few screen glitches in the Open file window. Is there a patch for this? I am wasting a lot of time selecting, opening and saving files. Not good as this was not a problem in Sierra. MacBook Pro Retina 15"

Just bought the new 2.9 GHz Intel Core i9 Macbook Pro running Mojave and having huge issues--- Illustrator is SO SLOW!

[[NOTICE:]] SAYING THIS AGAIN BECAUSE IT WAS MY POST, AND I FOUND THE SOLUTION WHICH WAS TO DISABLE DICTATION. HOPE THIS HELPS!

I really dislike that this Adobe admin has given the completely wrong answer/advice and has a big green sign saying COMPLETED.

And yes, the solution is to disable Dictation, thank you Nick de Bruyne

I have 23.0x and still not usable. As soon as I start Illustrator I cannot use anymore ESC function key on Power Mac PRO (ESC is software key) and also all is happening like random clicks, I cannot control anything.

Hey, so I fixed my problem finally after some more Googling and you won't believe what was doing it! It was MacOS Dictation mode. After reading someone's solution I disable the OS Dictation feature and the problem is GONE.

Can you believe it. Adobe folks, please look into this.

I have the same problem. Illustrator very slow choosing instruments, seems to freeze for a couple of seconds. Updated to Mojave and to Illustrator 23, deleted preferences. No results... Could you help me?
MacBook Pro 2017, 1 TB SSD, 16 Gb RAM
Graphic Board: Intel Iris Graphics 650 - Version: 4.1 INTEL 12.0.34 - Memory: 1536 Mb

I've since updated to 23 and it's still giving me all the same issues. Illustrator is simply unusable, doesn't matter if I use CS6, CC 22 or 23.

If I try use the app everything just constantly messes up, random movements and selections and so on. I can't use Ai AT ALL right now!

23 crashes all the time too on MacBook. Any known issues?
