@jugglinmike this is the most extreme solution to our "Login Item" notification problem...

Another way of approaching this might be to try just closing notification windows whack-a-mole style... I found a couple of suggested solutions that do that:

• https://apple.stackexchange.com/questions/300317/applescript-how-to-close-notification-alerts-from-a-specific-application

i did a quick test run at https://github.com/bocoup/aria-at-gh-actions-helper/actions/runs/13190188129/job/36821463477 and it looks like the killall command is causing the step to fail and fail the whole job. maybe we need to wrap it in something to make sure it emits a status of 0 regardless, or maybe this is early enough in the steps that the notification center isn't booted yet and we don't need the kill command?

Ooh thanks for trying it out! Will try removing the killall command

lgtm!

Ran a new flakiness test on the disclosure-navigation test plan and confirmed there were no instances of that Login Item notification popup VO announcement. Also, it looks like the inconsistency rate on this run is back down (and a little bit improved) from the Dec run (13% on this run vs 14% on the Dec run). This is a big improvement from the 20% error rate in the latest Jan run.

@jugglinmike I'm curious what you think of this solution since we were discussing possibly upstreaming something back to the guidepup setup....
