I can consistently crash Illustrator by dragging a swatch to the swatch palette

[spaceprobe]

Title says it all, really. If I make a colour while the outline colour box thinggie is selected and drag it into the swatch palette - either from the colour palette or from upper part of the swatch palette, Illustrator instantly quits without warning.

Lost a lot of work the first time it happened - it seems Illustrator hadn't saved any recovery data for 40 mins or more for some reason.

Mac M4 Pro, Sequoia

Illustrator 29.2

It bmay be a good idea to reset preferences to fix both issues.

There is a free plugin from Astute Graphics

If you can't trust the built in auto save

I guessed this would be the answer, but it's not a trivial thing - resetting prefs is such a PitA - and doing it just to see if it might work (basically, Adobe's job - we do pay them huge amounts of money, after all) is a double PitA.

This is a brand new Mac - I only installed Illustrator a couple of days ago.

I'll let it develop until I can't stand it any more then I'll give it a try.

Quit Illustrator and rename the preferences folder.

That way your preferences are kept and you can check out if it help at all.

You do reboot the computer regularly?

[spaceprobe]

Yeah, I'll do that.

Reboot - hardly ever, but because it's a newly set up Mac it has been rebooted a few times. Last time was yesterday middayish.

OK - I have now updated Illustrator to Version: 29.2.1 (29.2.1), reset the prrefs and restarted the Mac and I'm still having this issue.

Does anyone else have it?

Save your work! In an RGB document (this may not be important), make a colour in the Colour palette by dragging the sliders, then just drag the colour into the Swatches palette. For me, Illustrator crashes instantly.

I have previously deleted colours I don't want by select all unused then click wastebin. This is the error report...

Tested it on an M1 and an M2: does not crash.

Does that also happen in Safe Mode?

[Ton Frederiks]

Tried it yesterday and today following your steps, but cannot replicate your crash.

Maybe someone from Adobe support can have a look into your system.
