I ran the `88. PlaybackPerf.VP9.1080p60@1.5X` test on a bunch of different Macs in the office. This test has consistently high numbers on the graph page for [dropped frames for VP9 videos on macOS](https://health.graphics/playback/details?platform=mac&browser=firefox&encoding=VP9&past=week&ending=2019-10-15). However, out of the five Macs tested, only one showed any dropped frames at all, and it was a very old machine.

 - MacBook Pro (Late 2016), 10.12.6: no dropped frames.
 - MacBook Pro (Early 2013), 10.14.6: no dropped frames.
 - MacBook Pro (Mid 2012), 10.15: no dropped frames.
 - Mac mini (Late 2012), 10.13.6: no dropped frames.
 - MacBook Pro (Early 2011), 10.9.2: ~200 dropped frames.
