Unable to launch Illustrator on macOS Tahoe

I've been having an issue with both After Effects and Illustrator on macOS Tahoe 26.6.2 (MacBook Pro, M5 Pro, 48GB RAM). Both applications crash just a few seconds after launching, leaving me with no option but to force quit them (I can't even choose to start on Safe Mode on After Effects). I was using both apps earlier this year on the same computer without any issues or performance problems. However, for approximately the past two weeks, I've been unable to use either application or open a project. Photoshop and Premiere Pro are working normally, although Premiere Pro did experience a few glitches recently that eventually stopped on their own. I've already tried installing previous versions of both apps, Illustrator 29.8.1 and After Effects 25.6.5, but they still crash shortly after launching. I also had Wacom software installed, so I completely uninstalled and removed all related files and components to rule out any possible conflicts, but the issue still persists. As an additional test, I installed After Effects 2026 on a Windows PC, and it launched and worked normally. I don't know if the issue could be related specifically to macOS Tahoe or to something on my Mac that is causing both applications to crash.Please help! 

I’ve got an Intuos Pro M PTH 651 and was not able to launch Illustrator or configure the tablet using the current driver (6.4.10-3). I removed it and installed the previous version (6.4.9-2) and now I everything works.
 

I don't have a wacom driver to install or uninstall, but Illustrator is just giving me this, and I have done everything they say with 'Permissions'  - same thing over and over...any ideas?

Worked for me!

Had a frozen MacMini M4, new and frashly installed with the needed software apps, read some of the comments. Trial and error: Checked transparencies in System ≥ Access ≥  Screen ≥ engage 'Deminish transparancy'. (Translation on the fly, work in another language)
Seemed to work!

After I happily resolved my driver problem that stalled Illustrator, I learned something worse.

The Wacom drivers for Mac OS Tahoe do not support the Intuous PTH-651 tablet that I use.  Wacom support confirmed that I had to return to OS 15.x or buy a new Wacom 2025 edition -- it became my 3rd forced obsolete tablet, the other two were obsolete because cable input changed.  
Despite my feelings about Wacom in this, I bit the bullet and went with XENCELABS and could not be happier. It was 35% less, twice the resolution, comes with so much more than Wacom.  Even the tablet surface has more natural grit to it than the mirror-feeling I got from the Intuous for 8 years.

How I wish I'd known this before I let Adobe support trample all over my fonts and plugins - grrrrrr

Uninstalling the wacom driver did the trick for me aswell. Thx! 

Since updating my MacBook Pro to macOS 26, I have a recurring problem with Adobe Illustrator. Every time I close Illustrator and try to reopen it, the app freezes on launch. The only way to make it work again is to completely restart my MacBook.

What I’ve already tried (without success):

• Reinstalled Illustrator (5–6 times)

• Reinstalled Creative Cloud

• Tried older versions of Illustrator

• Reinstalled macOS 26 from scratch

System details:

• MacBook Pro (Apple M3 Max, 48 GB memory)

• macOS 26.0 (Build 25A354)

• Illustrator latest version (also tested older versions)

Is anyone else experiencing this? Could this be an Illustrator compatibility issue with macOS 26? Any suggestions would be greatly appreciated.

Thank you
