3. MOOS Project Viewer

MOOS Project Viewer allows you to open, view and print any Microsoft Project file. Previously, MOOS Project Viewer used Java required Java to run and we don’t recommend having Java installed on your Mac unless it’s really essential because of the security risks involved.

However, since MOOS 3.0, the application no longer requires Java and can be downloaded and installed safely.

MOOS Project Viewer opens any Microsoft Project file including MPP, MPT and XML and all MS Project versions 2000, 2003, 2007, 2010, 2013, 2016 and 2019.

Note that MOOS won’t automatically associate itself with any Project files you want to open.

To open a Project file using MOOS, you’ll have to hold down the Ctrl key and click on the Project file you want to open and select Open With… and then “Other” and select MOOS Project Viewer from the Applications list.
