Project Viewer 365 allows you to easily view Microsoft Project files on your Mac for free.
Project Viewer 365 is made by the makers of Project Plan 365 which we rated one of the best alternatives to Microsoft Project on a Mac.
The nice thing about Project Viewer 365 is that it can open files directly from several different sources including from a URL, GoogleDrive, Dropbox, SkyDrive, Sharepoint and Mail attachments.
You don’t even have to download the MPP files onto your Mac although if you do, it can of course open files from your Mac hard drive.
Project Viewer 365 is compatible with all versions of MS Project including MS Project 2013, 2010, 2007 and 2003 and includes all standard MS Project view types i.e. Gantt Chart, Task Sheet and Resource Sheet.
You can print Project files from your Mac and convert them to PDF.
You can also upgrade Project Viewer to the MPP+ plan for $10 per year which allows advanced features such as the ability to generate reports, customize grid tables, advanced sorting and filtering, customized timescales, resource/task usage views, network diagram views and calendar views.
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.
