Status: RESOLVED FIXED

From googles instructions looks like you can cross compile to arm64 from an intel mac. I tried one here last week out of curiosity, and the build time takes about 11-12 hours.

we would probably also have to grab the chromium ARM driver so the chromium fetch should be modified for that to run the performance tests

making note we'll have to add a fetch for chromium arm mac https://download-chromium.appspot.com/?platform=Mac_Arm&type=snapshots as part of this bug

Based on https://bugzilla.mozilla.org/show_bug.cgi?id=1858740#c9 I will probably continue building this with the intel OSX workers

This patch updates the chromium fetches to now include the ARM builds so
that we can use the appropriate chromedriver for CaR apple silicon
builds.

Depends on D192712

tasks seem to be passing https://treeherder.mozilla.org/jobs?repo=try&tier=1%2C2%2C3&revision=4a1dcf5f2f83a1264fb3665713c37f8a644da925&selectedTaskRun=c7QBjBfMSLKWtwsdNGCudg.0

but I think that is actually using the intel mac chromedriver rather than the arm chromedriver. I need to double check

looking at the Trace, looks to be working as expected though
