Use the complete set of features in Logic Pro for Mac
Logic Pro for Mac provides the power and flexibility of a complete professional music production system, while also allowing you to work in a simplified mode that streamlines tools and menus across the app to provide you with a core set of features for music production.
Complete mode: For experienced users who have upgraded from earlier versions of Logic Pro or worked with other DAW apps, the full set of Logic Pro features and options is active. Complete mode is active by default if older versions of Logic Pro have previously been installed on your Mac.
Simplified mode: Users new to Logic Pro can start working with basic features and a simplified interface. In particular, if you are familiar with GarageBand, you will find a direct match for most GarageBand features along with some additions. When you open an existing Logic Pro project, any tools or options used by the project are turned on automatically.
Turn on Complete mode
Choose Logic Pro > Settings > Advanced.
Select the Enable Complete Features checkbox.
Note: When the Enable Complete Features checkbox is unselected, Logic Pro is working in Simplified mode. The Simplified Mode button appears in the upper-right edge of the control bar, showing you the working state. You can click the Simplified Mode button to open Logic Pro > Settings > Advanced directly, so that you can turn on Complete mode.
In the Logic Pro User Guide, features that require Complete mode have this icon: 
.
If a Logic Pro project makes use of a feature (for example, track stacks) that can only be created or edited in Complete mode, items using the feature will still play back when operating in Simplified mode.
