I swore off Flash for a long while, until the great Safari support in Mavericks. Now I use it without fear.
However, the updating is always a pain. It seems like when I go to certain websites the "Adobe Flash Player Install Manager" fires up and bugs me to update. I don't want to have to think about doing these Flash updates all of the time.
Is there a way to stay up-to-date while not having this app bother me all of the time?
