Symbolicate textual Electron macOS crashes

Usage no npm install needed!

<script type="module">
  import electronSymbolicateMac from 'https://cdn.skypack.dev/@electron/symbolicate-mac';



Symbolicate an Electron macOS crash report that is missing symbols. Wraps parse-breakpad with convenient parsing and downloading of symbol files.

This tool downloads the symbol files needed to symbolicate and stores them in a cache folder relative to the module. These files are large (~400MB) and may take some time download initially.

$ npx @electron/symbolicate-mac /path/to/crash

Note that the crash file must be the full crash, including the "Binary Images" section, or else symbolicate-mac won't be able to discover which exact version of Electron to use.
