More goodness from Brett Terpstra, with Bunch which, on macOS, lets you start a bunch of apps (and close them) quickly and easily. It’s pretty grape (Dad pun intended).
A link I’m finding I use a lot is this one: SugarCRM version 9.0 Enterprise Documentation.
From there you can access User/Admin/Developer guides and Release Notes. In other words, the right starting point for finding a lot of answers about how do things in SugarCRM.
