Use project alternatives and backups

When Show Advanced Tools is selected in the Advanced preferences pane, you can create alternative versions of a project, each with a unique name and different settings. Alternatives are saved as part of the project, and share the same assets. Alternatives for the current project appear in the File > Alternatives submenu.

Each time you save a project by choosing File > Save (or pressing Command-S), a backup of the current project alternative is saved (up to ten backups per alternative). In the Project > Revert to submenu, backups for the current alternative are listed in descending order from newest to oldest.

Create an alternative version of a project

Choose File > Alternatives > New Alternative.
Enter a unique name for the alternative, then click Done.

Edit project alternatives

Choose File > Alternatives > Edit Alternatives.
In the Edit Alternatives window, select an alternative from the list, then do either of the following:
- To rename the alternative: Click Rename, then enter a new name.
- To delete the alternative: Click Remove.
  You cannot remove the Main alternative.
Click Done.

Choose a different alternative

Choose File > Alternatives, and choose a different alternative from the list.

If you have made changes after you last saved the current alternative, a Save dialog appears, so that you can save your changes in the current alternative before switching to a different alternative.

Choose a different backup of the current alternative

Choose File > Revert to, and choose a backup from the submenu.
In the Revert to Backup dialog, click OK.
