Spacebar not working as quick hand tool on MAC – Adobe Illustrator

For me it was the LastPass application; I quit that and the spacebar started performing correctly in Illustrator again.

Same thing happened to me. Just shut down Word and the spacebar/handtool works again.

I've closed the MS Word and restarted my macbook and it worked. 

It happened to 4 people in our office, 

Turns out our Security system "WebRoot" was causing it, so we just had to tick "Pause Secure Keyboard Entry" from the top bar. Worked a treat.

Incase anyone else runs into this, sometimes Terminal can steal the spacebar command from Photoshop. I keep mine open for running utitlities and purging the RAM, but occasionally it messes with Photoshop. Quitting and relaunching Terminal fixes it.

You can also usually avoid Spotlight popping up if you hit the spacebar first and then hit command/ctrl.

As others have said, other apps tend to steal the command sometimes. It's annoying.

Holy Microsoft Word Batman. I had this issue and quitting MS Word corrected it. WHY! Geesh.

This works:
(tried a few things based on other sites/threads).

Save your work, close all Adobe apps
(didn't work for just Illustrator. I had to close Photoshop and InDesign to make it work)

Option + Click-Finder (in Dock): Relaunch
(Takes just a few seconds)

Opened Illustrator again and problem was solved.

Some threads also said they had to restart computer and issue was fixed. Mine worked just doing the Relaunch Finder thing.

FYI: I'm still running an older CS 5.1 but from my understanding, it's the same issue with the apps running, any version, even CC.

One helper said this issue happens at random times from using the Command + H (hide) in any of the apps. I know this or something similar has happened to me in the past but I've been a designer using Adobe products since 1990 and it's very rare to me.

Hope this helps someone 🙂

I didn't read the entire thread but when I quit Excel, the spacebar and spacebar + Command started working again. 

Hi,

I had to enable the 'Use OpenCL' on my M1 Apple MBP. Nothing else worked for me.

I got a new computer (iMac 2020/BigSur) and mine wasn't working either after installing Creative Cloud and Photoshop 22.4.3 update; very frustrating. Spent two hours researching for a solution with no relevant solutions.  I rebooted the computer, and now it works (insert annoyed face here).  Camera Raw was also opening greyed out.  Now it works too.
