Same here. I can't move any object. Very temperamental and annoying. I can nudge them with my arrow tool no problem. But when you have a billboard size file, forget it. Please fix adobe!!!

ダイレクト選択ツールでオブジェクトを選択し、移動しようとするとエラー音がして元の位置に戻されます。
グループ選択ツールでも同様です。
オブジェクトの種類(テキスト、リンク画像など)は限定されず、どのオブジェクトでも起こります。
キーボードの矢印キーで移動、バウンディングボックスツールに持ち替えての移動は可能です。

The "pre-released" version that Adobe referred to requiring users to download another app called "TestFlight", seems over-complicated and I don't know how it'll affect the current settings.

When will we get the official updated AI version instead of the pre-released version?

Same problem here. It's *really* affecting my workflow.

MacOS 11.6.5 (I can't upgrade to Monterey, am on a MacBookPro mid 2014)
16Gb RAM
Illustrator 26.1

I too, am too afraid to try this out.
For those of you looking for a temporary fix-- you can 'downgrade' to an older version of AI... I bumped back down to 26.0.3 and haven't had the issue.
BUT**** I did have an issue with it clearing all my preferences :( ***READ AHEAD:

I read somewhere that you are FIRST supposed to click "uninstall" on your current version, because it will prompt you to keep all your preferences/shortcuts/etc saved... ***I messed up and just went strait to the "install" button on the version I needed and it automatically uninstalled the newest-- and no prompt happened, and now I'm having to rebuild my entire workspace layout, re-program shortcuts- and more.
I do currently have about 10 tabs open on researching these forums to figure out how to drag and drop my saved workspace and shortcut files to the new program folder but it has been a mess and apparently other folks have had the worst luck with it.

SO, if you do go to downgrade, learn from my mistake. Worst case scenario, take a screen recording and scroll through all your keyboard shortcuts & general preferences; and screenshot your workspace so you have it to reference if you do still end up losing your preferences.
Hope this helps!

I also received the email from Adobe RE the pre-release Beta. Personally I'm too worried that that could potentially lead to more issues so I'm just resigning myself to dealing with the bugs from 26.1 until they release the official update.

Hi other designers, Adobe reached out to me and ask me to try the pre-released AI version. I didn't want to mess things up even more at this point. Has anyone tried that pre-released version, and how did it go?

it's definitely replicable, in that when it starts to happen it keeps happening. Something about adding the shift button in too quickly after the click.

Still having the issue as of today on the latest Mac OS and CC Versions

Same here........

2021 MacBook Pro M1 Max

Hi Adobe, please provide an updated Illustrator version that fixes this problem, it's super annoying when it happens.

@adobe—any updates on this?? This is having a significant impact on my work. I know this doesn't pertain to whoever reads this, but if you're going to make us pay rent for the rest of our lives, the least you could do is not break our tools.

Same problem. Started after upgrade to Monterey and latest Illustrator 26.1.

2021 iMac M1
Monterey 12.3
Illustrator 26.1
Apple Magic Mouse
Did not happen in previous version of Illustrator (running on Big Sur)

Same Problem

Big Sur 11.6.2

Did not happen in the previous version of Illustrator

Same, ever since the latest update.
Never seen this in 10 years of using ai.

iMac (Retina 5K, 27-inch, Late 2015)
MacOs Monterey 12.2.1

Same issue here

MacBook Pro 13-inch 2019
MacOS Big Sur 11.6

Illustrator Version 26.1

Yes, this exact thing, complete with odd green cursor. Started happening after 26.1 update.

Catalina 10.15.7 (19H1715)
Apple Magic Mouse

I have the same problems since the update to the Illustrator from Creative Cloud, updated this week, both my home Computer & Work computer have this issue.

OS: 11.6.4 (20G417)
iMac: (Retina 5K, 27-inch, 2020)
Processor: 3.8 GHz 8-Core Intel Core i7
Memory: 64 GB 2667 MHz DDR4
Graphics: AMD Radeon Pro 5500 XT 8 GB

Illustrator version: 26.1

This is something that keeps happening to me too, or when I select one object to move illustrator will freeze very briefly and a different object will jump to that position.

Is this cursor common to some function within illustrator on OS X, or is it an OS-level cursor of some kind?

I work on windows and have never seen this at all. Makes me wonder if illustrator's functions are being ignored in favor of some OS-level key combination.

**edit**

I see from this apple support page:
https://support.apple.com/guide/mac-help/pointers-in-macos-mh35695/mac

that this cursor is the OS X "copy" cursor, activated by option-click. I don't think this should be showing up within illustrator.
