Default to My Mac Instead of OneDrive
Good news. This has been fixed and will be available in the 16.12 update. If you get monthly updates, you should be able to update in April. To get the update sooner, you can opt into the Insiders program by going to Help > Check for updates and opt to get the Fast Insider updates.

I like the idea of allowing the user to select their default save location.
Why can't I select my mac as the default when applications open? I don't use OneDrive and having to tell my mac each time that I want to save the file to the mac instead of OneDrive is a pain. FIX THIS!
