Fusion 360 Crashes on macOS Sonoma 14.5 - Need Help!

[aaronbastian313WEX3]

Hi everyone,

I'm experiencing consistent crashes with Fusion 360 after upgrading my macOS to Sonoma 14.5. Here are my system specifications:

• iMac (20,1)
• Processor: 3.1 GHz 6-Core Intel Core i5
• Graphics: AMD Radeon Pro 5300 4 GB
• Memory: 64 GB 2667 MHz DDR4
• Fusion 360 Version: 2.0.19215 x86_64 [Native]
• Active Plan: Personal

Issue Description:

After the macOS upgrade, Fusion 360 crashes arbitrarily during simple tasks. For example, performing an extrude on a specific body or using the coil tool in one file triggers a crash. The Fusion "Report a bug window" pops up, the screen turns red, and the application immediately quits without showing the Apple crash report. Below is a video of this.

Steps Taken:

1. Updated Software: Both Fusion 360 and macOS are updated to the latest versions.
2. Reinstalled Fusion 360: Uninstalled and reinstalled Fusion 360, but the issue persists.

Additional Details:

• The crashes seem to be related to specific actions within the software.
• No Apple crash report is displayed after the crash.

Request for Assistance:

Has anyone else experienced similar issues after upgrading to macOS Sonoma 14.5? Are there any known compatibility problems or additional steps I can take to resolve this? Any advice or insights would be greatly appreciated!

Thanks in advance for your help!

@aaronbastian313WEX3 Are you sending in the reports to Autodesk? If so can you let me know a report ID so that I can find your reports inside the system? 

[aaronbastian313WEX3]

@RajkumarIlanchelian 

I have not. is this something I can do with the personal/education license?

As you can see in the video, fusion displays a pop-up window for me to report an issue, but the application quits before I can click send. Is that what you are referring to?

Sorry for the late reply. I appreciate your help.

@aaronbastian313WEX3 That pop-up UI is what I am referring to. So none of the times it comes up are you able to send them in? 

Can you try the below?

1. Close Fusion 
2. Go to launchpad - Fusion service utility
3. Run the repair Fusion

Now launch and run Fusion and see if that helps? Also, any pending macOS updates? 

[aaronbastian313WEX3]

@RajkumarIlanchelian sorry for the late response and thank you.

I have already tried running Repair Fusion to no avail. I am also up to date on macOS Sonoma 14.5. Maybe this has to do with the fact that I am on an intel based mac?

Also, I just updated fusion to 2.0.19440 x86_64 [Native] and the issue persists.

Thanks,

Aaron

@aaronbastian313WEX3 If you go into your Fusion preference - general - Graphics driver - what is it set to? 

If it is Auto-select can you set it to OpenGL? 

[aaronbastian313WEX3]

@RajkumarIlanchelian 

Hi Raj,

I switched to Open GL, but still having the issue. Mac OS and Fusion are up to date on the latest stable versions.

[RajkumarIlanchelian]

@aaronbastian313WEX3 Interesting. Does this machine have a dual graphics card? If so can you switch to the integrated one and see if that helps? 

Also, when you get the crash error report, if you do not click on it does it remain on the screen? If it does can you hit "return" on the keyboard that will submit the error report? 

[aaronbastian313WEX3 · Accepted solution]

@RajkumarIlanchelian Sorry again for the late response. Yes! I have this mac set up with an external GPU from blankmagic (link). I will try and force it to use the integrated GPU.

As for the crash report, it does not remain on screen if I do not click. I can try and smash return if I see it happening and see if that works, but I would be impressed if the submit button grabbed focus and let me submit as fast as it seems to happen.

[aaronbastian313WEX3]

I think the eGPU was the problem. It was splitting the load between both the internal and external GPUs which I assume must have caused it. I am going to try and figure out a way to make it only use the internal GPU, either by modifying the list file or by making a simple script I can run from my terminal that will launch the app specifying the GPU. Ill try and remember to keep you posted.

Any solution? I am having the same problem. Fusion seems to run on both a graphics and crashes with simple operations 

[RajkumarIlanchelian]

@orlando1 This is the same issue as discussed here - https://forums.autodesk.com/t5/fusion-support/fusion-mac-crashing-every-5-minutes/m-p/12981154/highl...

We are addressing this issue soon (possibly in our September update).

[aaronbastian313WEX3]

The only reliable solution is to turn off your eGPU while using Fusion. I tried changing the info.plist settings as well as some command line commands to force fusion to only use the internal GPU, but no dice.

I also identified that the issue happens when fusion tries to simultaneously split processes between the internal and external GPUs. I watched my activity monitor and I could see when a partial load jumped to the eGPU, the program crashed.

The most recent update does not fix the issue. As noted above, hopefully, this will be fixed in a September update. 

[RajkumarIlanchelian]

@aaronbastian313WEX3 The recent update that we put out a couple of days back is one of our minor updates and does not have the fix. We have a major update planned likely in September. 

This fix though is available in Fusion Insider builds. In my signature you will see a link to join the insider program. The insider build has this fix and that is the one that will go to production eventually.
