I just started using OneNote and I have a couple questions. First, my OneNote works okay but always freezes when I go to quit the application and causes me to force quit - every time.
Also, is there a way to search for tags on mac? I can't find the find-->tags command from the 'home' screen that tutorials talk about.
You are correct. You cannot search for tags on a Mac at this point in time. The best place to get answers on these types of questions is at Answers.microsoft.com as we have experts there ready to help. They will also be able to help you with your force quit question.
I’ve included a forum link about tags—https://answers.microsoft.com/en-us/msoffice/forum/msoffice_onenote-mso_mac-mso_archive/onenote-tag-search-missing-on-mac-when-will-the/8cc76d48-87b0-4099-a444-c93e446a23a6
that may help you out.
