This has been happening to me for a while too. Updated today (10/10/22) and it seems to be working properly.

I just started having the issue today, and I updated version 26.5 a couple of weeks ago. I found this thread looking for a solution.

Drag and click to align is definitely is NOT working in the latest version of Illustrator. Please fix.

It is now October 1st.

With the latest update to Illustrator (26.4.1) click-drag and click-option-drag fails to move even simple objects within the artboard to a new location. The shift key makes no difference either. When I click over the object a "+" sign appears, I'll drag the object and hear a pop alert sound and the object snaps back to where it started. After multiple tries I can sometimes get the object where I want it, but as soon as I release the mouse everything else around the object moves away as if they were reverse magnets. Using the arrow keys can move the object but takes far too long. This problem is infuriating and adds multiple hours to every job, and I can't bill for all of this extra wasted time.

Adobe, this needs to be fixed immediately!

I originally posted this in Community Forums for ver 26.1.

https://community.adobe.com/t5/illustrator-discussions/frustrating-selection-tool-behavior-with-ver-26-1-on-macbook-pro/m-p/12837070#M315539

The frustrating behavior is back in ver 26.4.1 and I am also using Illustrator on my iMac.

Had the same issue. Had to wipe my drive and reinstall earlier this week, which is how I wound up on 26.4.1 and it began happening afterword. Thought I was losing my mind.

I don't know where 26.5 is  — it's mentioned on Adobe's website as being the latest version — but as of right now, both CC and the Adobe site direct you back to 26.4.1. For the present, I rolled back to 26.3, which seems to have solved it.

Oddly, I noticed a repeat to the bug. Objects would "snap back" (along with the default system error sound) four times. After the fourth error, it would work correctly. Seems to have behaved this way pretty consistantly.

Illustrator 26.4.1
Mac OS 12.5 (21G72)
MacBook Pro (16-inch, 2019)
2.4 GHz 8-Core Intel Core i9
Magic Mouse 2

Forgot to mark it as critically important. I can't work in this version of illustrator like this. Please fix it.

This is a nightmare. I rolled back versions and still can fix it. My workrate has slowed down considerably because every single task is a chore. Please, Adobe, fix this.

This problem is occurring for me in version 26.4.1. If I use my apple track pad then I don't have the problem. This is very frustrating

Hi everyone,
With the new update (26.5), the problem we are having looks like gone. Hopefully it won't come back. Thanks to everyone for expressing their frustration on the issue. Knock wood we are good to go. If anything changes, I will update the situation. Also thank you Egor for raising the issue. Cheers

Hi jonbrong

I switched between an Apple Mouse II and a Logitech Mouse several times during my tests. In the process, I switched the mice on and off several times. This had no positive effect on me.

But nice if it helped you - possibly the problem was multilayered.

Many greetings Peter

May sound stupid but...

I just turned my Magic Mouse 2 off and then on and the bug appeared to go away.

*fingers crossed

Same problem here. Very frustrating. SOLVE IT!

Very frustrating, can't click and drag, keep getting green +. Please fix!

I'm having the same issue as well! I was on Adobe support yesterday and they did a remote support with my computer. After an hour or so, they couldn't figure it out so they're leaving case open until they find a solution.

For the time being, I reverted back to Illustrator 26.03 (John C.'s suggestion in this forum) and it stopped. Running OS Monterey 12.4.

Please fix this! Been dealing with it every day for the past 2 weeks, incredibly frustrating!

DO WE HAVE A FIX? The amount of rage I have for this issue is ridiculous!

Hi,

the problem with the "green cursor" only appeared when using Apple Mouse I and II. The older Apple Mighty Mouse with trackball worked fine, as did a Logitech mouse.

With the update to Illustrator CC2022 v26.5 the "green cursor" problem disappeared. This means green light for Apple mouse I and II.

Many greetings Peter

I can't believe this bug came back. It was just fixed with a previous version. I had to backdate to use illustrator again. Please fix this.

Very annoying! I thought it was just me and I was going mad!
Having the problem on M1 Pro with Monterey.
Unistalled and gone back to 26.03 which seems to fix
