Support for running under Rosetta 2 emulation on Apple M1?

[Marshall Greenblatt]

Hi All,

I have an application based on Chromium that supports crash reporting. When running the Intel app under Rosetta 2 emulation on an Apple M1 device the crash capture fails with errors (like [1]) that appear related to missing kernel functionality. What would it take to get crash reporting working under Rosetta 2 emulation? Would it make a difference if I was only interested in capturing the stack trace information?

Thanks,

Marshall

We have a macos app using crashpad code from early 2019, and notice we are not getting crash reporting when the app runs on M1. We cannot do native M1/Universal due to 3rd party constraints.

Does the latest crashpad support crash dumps under Rosetta 2?

[Mark Mentovai]

No, Crashpad doesn’t support this.

Hi all,

Is there any chance of reviving this? What is missing at the Apple level?

Thanks
