Unity 4.5 crashes every time I hit play (for the second time) - MacBook Air

4.3.2 worked fine on my MacbookAir. However, when 4.5 came out. It crashed consistently (when I hit "play/run" on top the second time (first time seems to work). I tried the new 4.5.3 version and I'm still having this issue.

UPDATE: 4.6.1 is fine!

UPDATE: Tried 4.6 beta (17) and exact same thing is still happening.

UPDATE: I have traced it down to an Application.LoadLevel causing the crash. If I use LoadLevelAsync, it's fine.

OSX 10.9.4

I saw the other post about the USB PS3 controller. I unplugged any USB devices and monitors, etc. so I'm just using the power cable and I still have this issue every time I hit play the second time.

Any ideas?

This is now happening on my desktop Mac Mini also. Is there any way I can research this or get help?

 

Does this happen on every project/scene? Including blank ones?

You can open /Applications/Utilities/Console.app and get a crash report from in there somewhere.

 

Is does not crash on an empty scene.

Do you know where I would look for the crash report?

-Carmine

 

~/Library/Logs/Unity/Editor.

If it does not crash on an empty scene, then one of your scripts is most likely doing something it shouldn't. If you dig through the log you should find an exception recorded, and if you're lucky it'll point you right to the problematic script.

 

This first one is where it fails, and I have it succeeding at the bottom...

I've downloaded the 4.6 (17) beta. I'm still getting a crash every time I hit play for the second time. Can anyone help?

 

Carmine, do you activate/deactivate/instantiate terrains ? I have a similar issue where my scene crashs when the terrain gameobject gets activated/deactivated - but only happens on MAC, it freezes completely.

 

Nope. I traced it down to an Application.LoadLevel. For some reason if I had it as Application.LoadLevelAsync it worked fine.

 

Are you using plugins? You may find you are having this issue if the DLL is not being unloaded correctly ( thread remaining open for example )

 

My issue is because I call Resources.Load inside ISerializationCallbackReceiver.OnBeforeSerialize.
The console shows "ReleaseAllScriptCaches did not release all script caches!" when the next time I hit play.

 

Hey, I encountered the same problem, and found a solution to this.
when you open you editor, the first thing to do is opening another scene, for example a GUI scene (not your start scene).
Then click "play" to run the other scene, then stop running. Then click "play" and stop again.
After finishing that , you can switch to your start scene, and editor won't crash anymore.
But you should repeat these steps after you close editor and open it again .

 

Thats amazing. I have had the problem for quite some time now. Every time I start Unity 4.6, play, stop, then start again Unity would simply freeze. One of the unity thread used max CPU. I've rewritten my background thread (think threadpool) system 4 times now and finally concluded that it was _not_ causing the problem (I do abort all my threads properly OnApplicationQuit). So I decided to Google some more, came across this unlikely explanation and tried it: Start Unity, new scene, play, stop, play, stop, load my previous scene, play, stop, play, stop, play, stop. No freezing. Thanks.

 

Has this been fixed in 4.6.1 dude?

 

Seems to be ok now.
