The DTK reported “Apple processor” in this spot, but shipping hardware now seems to use “Apple M1”. The DTK is no longer relevant, but for some degree of future-proofing, look for “Apple ” as prefix in the test. Test: snapshot_test SystemSnapshotMacTest.CPUVendor Bug: chromium:1222625 Change-Id: I6ead87ebe9aa078ef9a95e5bcc6a9e5ca8c3b55a Reviewed-on: https://chromium-review.googlesource.com/c/crashpad/crashpad/+/2976787 Reviewed-by: Nico Weber <thakis@chromium.org> Commit-Queue: Mark Mentovai <mark@chromium.org>
