This appears to me to be an Apple OS problem, not an Adobe problem. The same tool stopped working at the same time in Vectorworks, a CAD program I use. I suspect that every app (and there are quite a few) that use this shortcut will find it broken. It is really a drag for me since I spend most of my time in Adobe apps and Vectorworks. This stuff is expensive, more than it used to be, so all of these companies need to work nights and weekends to fix it. But they won't.

Spacebar+command doesn't work for the zoom tool either.

Additionally CMD + SPACEBAR does not invoke the zoom shortcut anymore.

I have the same issue. Will there be an update for a fix?

I quit chrome then restarted photoshop and illustrator (the hand tool stopped working in both applications) and the hand tool is back. Opened chrome again and the hand tool is still working, for now. Maybe this will help someone.

This is a very frustrating bug as this is a MAJOR workflow interruption. It's so ingrained. And these tools are not cheap! The last thing we need is something we're paying 60/month for, messing with our productivity. Clearly this is not an isolated incident, Adobe. Fix it.

MAC High Sierra, Illustrator 2020

The spacebar does not function at all as the 'quick' hand tool. Pressing (H) still works, but the basics (spacebar) does not.

Please fix!

Illustrator has become a complete joke. Adobe have lost the plot. Screen often won't redraw so you are working blind - the pixel grid is STILL not aligned properly and the bugs - OH the never ending list of bugs.. They are clearly prioritising features over quality - reliability and precision. Illustrator CS6 was the last good version - every extra release has been a step back.. Well done Adobe

Sorry for your guys who had no luck fixing it by my solution. I've just shared my experience. Besides, I've faced this issue before (It was about 2 years ago I guess) and that was about Chrome/Adobe as well. So this time I've just tried and got lucky.

As a guess, maybe it is not about Chrome exactly. Maybe it is about some specific web page and technology used on them and may appear while using Safari or Opers as well. Just a guess.

it seems to work and then not work with no pattern. i use it a lot so hope you can find the solution!

This is not working!!!!! Painful

I still have it in 2019. And the Chrome browser is note even launched.

Today all of a sudden I've got this issue. Restarting the Ilustrator did not help, BUT restarting the Chrome browser had magically resolved the problem.
Catalina 10.15.1.
Hope it'll help someone

After the 2020 update the spacebar shortcut sometimes works and sometimes doesn't. Restart didn't improve things. The same thing happens with Photoshop as well.

Same here, and I also turn to you guys to get it fixed soon, as it stops all my work. Does not work in both PS and AI

Make sure autoscroll is enabled in preferences!

The spacebar stops working not just in Ai but Ps and Id as well. This is crippling to productivity :~(

I see Christina mentioned that the "H" key brings up the hand tool BUT - unlike the space bar shortcut - when you remove your hand from the "H" key, the hand is still there. This is causing me major headaches in my workflow. I see this issue was first brought to Adobe's attention in June. Not a very impressive response from Adobe. Especially when people are paying $60. month for CC.

Has there been no update on fixing this? I did the 2020 update yesterday and I'm now having the same problem! Causes a serious problem when trying to create work and move around the artboard!

Same! Please get this fixed, it's essential to lot's of peoples workflow.

Same for me, worked yesterday but today the quick hand does not recognise the spacebar as a command. Major issue for me since I use it probably 30 times a minute working full-time in illustrator. Tried to change the command back manually but didn't work.
Any solution??
