marvfash Thanks for your reply! I have tried the followings but could not reproduce the problem:

• Move the Spine 4.2.20 window to an external monitor immediately after launching it on the MacBook screen.
• Set the external monitor as the main display and launch Spine 4.2.20.
• Mirror the MacBook screen on the external monitor and launch Spine 4.2.20.

(4.2.20 is currently the latest version.)
I tried each method about 3 times each. I tried launching Spine directly and launching it by opening a Spine project, but unfortunately I could not reproduce the problem.
I would like to reproduce the problem, but the conditions still seem to be lacking. Is there anything else specific to your environment?

Misaki Nothing I can think of.
I also have not faced this bug since I posted this but I'll try to reproduce it and capture my screen while doing so.

abuki Thanks for your report! It's good to hear that it's already working, but I'm sorry that it doesn't seem to help us reproduce the problem... Is your macOS version still 14.1.2?

abuki

I am currently on 14.4.1

Hmmm, I see.

Yes, it is good to know that disconnecting the external monitor seems to be an effective workaround.

Just wanted to add that I am also running into this issue, even without an external monitor connected.
I tried deleting settings and other suggested fixes but nothing was working.

Finally, I tried changing my computer's display resolution and opening Spine while using the lower resolution and that seems to have worked. I was then able to change the resolution back to normal and it seems to be working now.

It definitely seems like there is some issue with the graphics initialization on mac. For reference I'm using an MacBook Pro with an M2 Max with 38 core GPU and 32GB ram, running Sonoma 14.5.

samanabo Perhaps I spoke too soon. It seems this workaround only worked once. I'm currently unable to open Spine again.

samanabo I'm sorry to hear you're having trouble. Could you post the spine.log file to this thread? It should have been created at the following location:
~/Library/Application Support/Spine/spine.log

Misaki Here is my log file. I have another possible cause... Spine seems to only crash when I have a PS4 controller plugged in. If I unplug the controller then it launches fine.
Is it possible this is caused by the audio device in the ps4 controller?

samanabo We've fixed this in the Spine launcher version 4.2.17, available now. We're super happy to have this fixed! Thanks a lot for your report and follow ups, that was very helpful to figure out the problem.

Everyone having this problem will need to download the latest Spine launcher and reinstall.

Hello all, sorry to dig up an old thread but I thought it would be better than starting a new one.

I've recently been hitting this error as well. It happened yesterday on Spine 4.2.29, running MacOS 14.4. I upgraded to MacOS 14.5 just in case and that seemed to fix it. However booting up my machine this morning I'm getting the same error again.

I've tried deleting settings but no luck there. Based on the posts above I wondered if it had anything to do with external monitors but unplugging everything has no effect. I've emailed through my spine.log in case that's any use. I have no antivirus on and Spine has been working perfectly until yesterday!

If there's anything I can do to help track this bug down please let me know and I'll be happy to assist.

Just a quick follow up on this one. I needed to work with Spine today, so I opted for a clean install of the software and that fixed it. I will update if the bug comes back, but I guess a clean install is the way to go?

We recently did an update to the launcher to solve some issues with MacOS.
When you did the clean install, have you downloaded again the launcher? If yes, that might have fixed the problem.

If it happens again, it would be useful if you could attach the spine.log file.

We received your spine.log, thanks. Your Spine launcher is 4.2.03 so the first thing to try is to download and reinstall Spine from your Spine license page. The newer launcher should fix the issue.

Just want to confirm the newest version of Spine fixed this. Had the crash came here updated Spine launcher and all working again. Thanks for maintaining this software so well. Using on macOS 14.5 with external Wacom Cintiq connected as second monitor to M1 Mac mini. FYI.

Hello again, sorry to once again dig this up, but I am still experiencing this error in spine 4.2.35

It still appears to be isolated to when I have a playstation controller plugged in. The issue goes away if the controller is unplugged while spine is starting.

samanabo Please download and reinstall Spine so you have the latest launcher.

Nate Thanks for the quick reply.
Updating the launcher itself does fix the issue.
