I want to stop this prompt: Normally I’d encourage people to keep their system / app up-to-date, but there is only one word that can describe what Microsoft had done in Office for Mac: catastrophe. Their Apr 2018 update destroyed the ability to display / assign Asian font correctly. Prior to the update, I can view & set Asian font using the Asian name of a font family (e.g. "細明體" instead of "PMingLiU"). But after update all fonts are displayed using English font family name. I can stil use these Asian fonts, but it's no longer be compatible with Windows version. Besides, the performance is severely declined after update: the text input curser can’t even catch up with my typing speed. I've managed to revert to older version via Time Machine backup. This is not the first time that Office update ruined everything so I'd always make backup before applying for update. Now I just want to stop this annoying prompt. [EDIT] Yes I’ve already set Microsoft Auto Update to “Manually Check”. The problem is all Office apps keep bugging me & asking me to check updates.
