Opening Logic Pro
There are several ways to open Logic Pro.
However, before you do so, you should decide whether you want to open Logic Pro in 32- or 64-bit mode. The main advantage to using 64-bit mode is that you can access large amounts of memory—when working with software instruments that require loading very large sound libraries, for example.
Navigate to and select the Logic Pro icon in the Applications folder.
Choose File > Get Info.
Do one of the following:
Select the "Open in 32-bit mode" checkbox to open Logic Pro in 32-bit mode.
Deselect the "Open in 32-bit mode" checkbox to open Logic Pro in 64-bit mode.
Double-click the Logic Pro icon in the Finder > Applications folder.
Click the Logic Pro icon in your Dock.
Double-click a Logic Pro project file.
When you open Logic Pro for the first time, the Templates dialog is displayed, allowing you to select a template for the project type you want to create. (For more information on the Templates dialog, see Creating Projects.) The setup of the Logic Pro interface depends on the chosen template.
