Can Merlin Project view files from MS Project?

Yes, Merlin Project can open, import and export files from Microsoft Project. But there is also a trick to use Merlin Project as a free viewer for MS Project files. Keep Merlin Project – even after the demo is expired – on your Mac. Just double-click on any mpp file and Merlin Project immediately displays the contents of the file. However, after expiration of the demo version you cannot make any changes.
