I have used the Mac on and off for the last several years. However I. can not figure out this issue and how to make it stop. If I am reading an article and I do a two finger swipe down or a VO a to read all if I get a notification like mail for example Voiceover stops reading and reads me the new alert I like this method some times but when I am working in particular I don't want to hear every mail notification preview being read. Can I stop this temporally somehow?
