# Profiling the Atom Render Process on macOS with Instruments
|
|
|
|
|
|
|
|
* Determine the version of Electron for your version of Atom.
|
|
* Open the dev tools with `alt-cmd-i`
|
|
* Evaluate `process.versions.electron` in the console.
|
|
* Based on this version, download the appropriate Electron symbols from the [releases](https://github.com/atom/electron/releases) page.
|
|
* The file name should look like `electron-v1.X.Y-darwin-x64-dsym.zip`.
|
|
* Decompress these symbols in your `~/Downloads` directory.
|
|
* Now create a time profile in Instruments.
|
|
* Open `Instruments.app`.
|
|
* Select `Time Profiler`
|
|
* In Atom, determine the pid to attach to by evaluating `process.pid` in the dev tools console.
|
|
* Attach to this pid via the menu at the upper left corner of the Instruments profiler.
|
|
* Click record, do your thing.
|
|
* Click stop.
|
|
* The symbols should have been automatically located by Instruments (via Spotlight or something?), giving you a readable profile.
