Prerequisites
Installing TotalView on the macOS comes with some prerequisites.
1. Make sure every user who might need to debug is in the _developer group.
2. Optional: Enable developer mode:
Enter: DevToolsSecurity -enable.
3. Optional: Remove the authorization prompt:
Enter: sudo security authorizationdb write system.privilege.taskport allow.
4. Classic UI only
The TotalView classic UI requires that XQuartz be installed on the machine where TotalView is running. Note that the classic UI is supported only on Apple x86-based systems.
The installer should not result in any errors. If errors occur, see Troubleshooting macOS Installations in the Reference Guide for information.
Running Multiple Displays
If you are running TotalView on multiple displays, you may wish to uncheck Displays have separate Spaces under the Mission Control preference. This avoids potential display problems in which the TotalView UI could appear partially out of the display.
