I just updated from QB Mac 2012 to 2015 (version V16.0.3 R4 Build 1460) and I have two users I need to delete. I open preferences and “users and passwords” and then select the user I want to delete. I’m SUPPOSED to be able to click on the minus sign to remove them but it is grayed out. I’ve restarted my computer, tried added a password to the Admin account and the user accounts, then tried deleting the passwords, restarted again, etc. and nothing works! Any help would be greatly appreciated!
