Unity freezes on macOS Catalina

Unity versions 2019.2.9f1 and 2019.2.8f1deadly freezes on macOS Catalina 10.15.

This happens when you edit animations in the UI animator controller as well as when the game is running in the player and you try to rotate the camera as in the editor via opt-left mouse click.

Unity just stops responding. Any attempts to close it with force quit do not lead to anything. Only rebooting the OS helps.

System Version: macOS 10.15 (19A602)
Model Identifier: MacPro6,1
Processor Name: 6-Core Intel Xeon E5
Memory: 64 GB
GPU: AMD FirePro D500 х 2

 

Yikes. Please be sure to file an actual bug report, in addition to discussing it here!

 

I have the same issue with Catalina and Unity 2019.3.x. Did anyone found a workaround?

 

Hello! After freezing and rebooting mac, this mono crash file appear.

 

having the same problem every time i try to quit end up having to force quit and sometimes after restart objects in the game have gone..i mean totally gone....i hope theres a bug report by now as its April 2020 and none of the new release seem to have fixed it.

 

@andrews_unity: I have filed a bugreport for it here: 1237826

 

@andrews_unity I'm not 100% certain, but it certainly looks like it to me.

 

This issue is related and similar but the cause is different so please allow me to post it here (if I need to open a new topic I'll do so)

Unity freezes here too from time to time. There is no apparent place where it starts.
I work in unity for several hours without a problem but once the MacBook went to sleep or screensaver, or I am idle in a browser or different tool for tool long unity simply freezes.

Here are a few scenarios:
I started to remember what I was doing because it happens so randomly
– sometimes it happens when I was painting tiles, sometimes when I was coding.
– Yesterday it happened when I was searching an asset in the asset store (browser) this exactly took me 5 minutes, returning back to unity I had to force reboot as unity was frozen and wasn't able to force quit.
– This morning Unity froze when I was assigning prefabs to my components, stood up for taking a cup of coffee, returning to unity: froze.

The icon in the dock also often is not responsive – I often have to click two to three times to bring up unity.
This does not happen with any other software in the dock. Switch with tab to unity from another application is responsive.

Unity version: 2019.3.7f1 (personal)

Same here: when working with Timeline, Animator and Animation panels the editor hangs and I need to brute-force shut my Mac, because the editor windows prevent a proper shutdown or restart

Could you find a solution ? cause the work is really getting affected. just few days back There was a major issue of visual studio compatibility with unity 2019.3.11f and yet Unity 2019 still freezing while editing animations is really killing time

 

i'm getting random crashes on in the animation editor, but not locking up, i'm in mojave, but i'm working on the same project as unity_kebjfGhLGcQB3A

 

Same problem for me, once I work in animator unity crashes. And only rebooting helps

MacOS catalina

13 inc MacBook Pro

 

This happens for me as well. I am here because it's happened 3 times today within the span of 45 min of work. I normally experience it after my computer is idle, once or so a day. Today it's happened in response to me interacting with the UI, either by selecting a game object, moving a tab, or zooming in or out with my mouse. I am unable to work on my project currently. This has happened with every version of 2019.3. I feel I should also note I am using a Logitech G602 mouse. Probably irrelevant, but I got the mouse about the same time I started using Unity 2019.3.

the crashes in the animation editor has been identified and unity developersa re working on it
https://issuetracker.unity3d.com/is...eviewing-animations-with-animator-window-open


i think i have found a workaround, the crash only happens when both the animator and animation windows are visible, i put them in tabs in the same windows so i can only see one of them at a time and it's stopped crashing.

 

This has also been happening with me on my mac too. Anytime the editor is idle for a period of time (an hour or so) it will freeze and then needs to be force quit. Occasionally it does recover if left for a few minutes and I leave the window active whilst clicking around; most times this is not the case.

 

Crashes for me too even without the animation window active.
It happens when returning to the editor after some time

 

crashes after inactivity sounds like a completely different problem. perhaps you should start a new thread. and file new bug reports.

 

Same Problem here.

 

It's not a crash as in that unity closes.
Unity just becomes unresponsive and the spinnging beachball appears when returing to unity, and then force quit is the only way to close unity.

 

Today is an update. Any news on bug fix?

 

I've had Unity freezing as well. For me its if I leave the Unity Editor running for a few hours, doing nothing. It actually locks up the Mac. Once I had a dialog telling me I was running out of system memory and should quite Apps. I can't say for sure it was the Unity Editor but I suspect it is a memory leak that is using up all the system memory while the Editor is idle.

 

@demuradze After I updated to 2019.3.15f1 I immediately got the full system freeze crash. A few versions ago there used to be a UI issue where the fonts got messed up. It seemed to go away, but not it's back in full force––even worse than before. Also, there is a new graphics glitch. The stage just has little white blips.

*I added the black boxes for privacy*

 

I'm getting full system lockups that last from a minute to restarting my Mac. It's happening to my colleague as well and he's on the newest version of osx.

I'm also getting terrible UI bugs like the previous poster mentioned. Garbage text to missing characters.

Edit: literally as I go back to work Unity is locking my system with every UI edit.

Edit Again: restarted Mac. Start Unity. Try to work. Immediately my system locks again

Edit Possible Solution: Ok I think I may have the culprit. I had the vfx window docked on a floating panel and I think it was auto compiling constantly because I wasn't in the graph. Since I've closed it I've had no freezing.

 

Is there any fix for this?? I see this all the time, I cannot run my project more than roughly 5x back to back without Unity (not responding) and I have to run a Force Quit.

MacOS 10.15.6
Unity 2020.1.0f1

 

I'm having the same issue on Unity 2019.4.7f1

when editing animations then hitting play, unity will lock up for a while then spring back into life.

Often Unity will just crash when hitting play.

at least once I got a KP and Unity crashed Catalina.

 

I am facing the same issue. I got this popup: “developer tools access needs to take control of another process for debugging to continue”. And then Unity just froze, force quit Unity didn't actually quit the Editor window, and there is no way to close it. My Mac's fan was spinning like crazy when it froze, I had to reboot my Mac. Please fix this issue as soon as possible, I couldn't work now.

My versions:
Unity 2019.4.9f1
macOS 10.15.6

 

i have a similar issue, iMac crashes/restarts every 30 minutes with unity open.

Unity 2019.4.9f1 - Mac os catalina 10.15.6 (19G2021)

 

Is this an issue with UIElements or GraphView in general? An SDK I am attempting to use (VRChat Udon) Is experiencing the same freezes described in this thread.

Unity 2018.4.20f1 - macOS 10.15.6
