Eclipse IDE for ModusToolbox Quits Unexpectedly on macOS Big Sur - KBA233132

Version:**

Question: Why did the Eclipse IDE for ModusToolbox quit unexpectedly on my macOS Big Sur machine?

Answer: For some macOS machines running on M1 processors, the Eclipse IDE may fail to start with a message such as:

"ModusToolbox quit unexpectedly."

The message details also state that the "attachment of code signature supplement failed."

This problem occurs any time that Eclipse was last opened in an empty workspace prior to a reboot. After the reboot, the application fails to start.

Run the following command in the /Applications/ModusToolbox/ide_x.y/ModusToolbox.app directory:

xattr -dr com.apple.quarantine *

Note: You may have to adjust the path if you installed ModusToolbox in a non-default location.

When complete, launch the Eclipse IDE again. This workaround works for all cases so far discovered.
