.mjm files are music score files. The .mjm format is the proprietary music score file format used by Majian Music to sell music publications by digital download.

The software needed to print an mjm file is MPrint. MPrint can be downloaded here.

MPrint is a safe app, written by Andrew York for the sales of his music as digital files. MPrint is available for Mac and Windows, but does not run on tablets or phones.

Installing MPrint on Macintosh:

When installing MPrint on Mac computers, Gatekeeper will often block the installation. Gatekeeper must be turned off to allow the installation of MPrint. The reason for this is Andrew's decision not to follow Apple's protocols using security certificates, which often did not function properly. Andrew York wrote the software himself for the sales of his music, and there are no third parties involved. Andrew guarantees MPrint to be virus and malware free.
