The Beijing Macintosh Union refers to two organisations:
- One is the Macintosh user group known as the "Beijing Macintosh Union", which "succeeded" the Beijing Macintosh User Group on April 3, 2004, and was later disbanded on October 15, 2004;
- The other is a Mac-related umbrella organisation in Beijing, which was formed on July 25, 2005.
The term "BeiMac union" (lowercase U) refers to the user group as the "Beijing Macintosh Union". However, the new umbrella-like organization is to be referred to as the BeiMac Union with an uppercase U.
