Organization
Day-to-day management of the organization was balanced between the senior full-time staff: business manager Harry Critchfield, technical manager Steve Costa, and support manager Randy Simon.
Business

BMUG's finances and business operations were managed by Harry Critchfield and Alisa Schulman, better known for her role as a DJ at
KALX. In 1995 Anne Wrixon replaced Harry Critchfield,
and in 1997, Wrixon was replaced by Hal Gibson, who remained until the end.
Technical

One of BMUG's principal operations was collaborative Macintosh repair and maintenance. A benefit of BMUG membership was hardware repair (and often recovery of lost documents from floppy and hard disks). The technical operations were managed by Steve Costa. Electrical engineer Chuck Meyer conducted many of the trickier repairs. Herb Dang was a fixture in BMUG's technical services, and his son Frank continued that tradition into a second generation.
Support

BMUG maintained a Macintosh support call-center, which helped users around the world by answering questions and helping them resolve technical problems with their computers. The support operation was managed by Randy Simon, and staffed by volunteers.
While much of the support operation dealt with assisting users whose computers had crashed, a significant portion of it dealt with the specific "vertical market" of

software from its comprehensive library on
400k and 800k 3.5" floppy disks. BMUG's shareware disk duplication and distribution program was run by Art Lau and Gerald Raddatz, supplemented by the efforts of many of the other volunteers.
Initially, William (Bill) Gandy was approached by Dr. David L. Foster, a Professor at UC. Berkeley, who asked Bill Gandy to donate his incredibly huge library of Freeware and Shareware software for the Macintosh. Bill had obtained the software while still a teen, working at the Computer Store of Oakland.
Bill had been approached by an Apple fellow, by the name of Phil White, who saw that Bill was a phenomenal sales person for the Computer Store of Oakland. Phil White felt that it would be an opportune method of getting the Macintosh software into the hands of someone who could "spread the word", about all of the cool software that was in Beta and was right around the corner.
Bill turned around and in the true sense of philanthropy donated to Dr. Foster an incredibly large volume of Beta software, which became one of the primary ways in which BMUG started to make money by selling the disks to students, faculty and any other member or visitor to BMUG. This of course attracted an incredible amount of attention to BMUG as the Macintosh barely had 3 actual pieces of software that were being sold. Literally there was only MacWrite, MacPaint and Multiplan (the forerunner to Excel).
BMUG's memberships began to swell exponentially as the word spread across campus and eventually around the world, that BMUG was the place to get Macintosh software, when no one else had "Diddley-Squat" in terms of software offerings. This attracted so much attention, that the initial halls and auditoriums were insufficient to hold the now burgeoning ranks of BMUGgers as they literally had to find new lecture halls and auditoriums after every meeting, until they could only be held in Sproul Hall, one of the largest auditoriums on the Berkeley Campus. Funny how a little thing like software could turn into such a prolific collection of Software Distribution.
But that wasn't all, because as word spread, then Macintosh Software makers and Hardware manufacturers began visiting and showing off their products and some extremely crazy dynamics began to take shape. For instance, BMUG began to accumulate various Macintosh Hardware, because when manufacturers would show off their Hardware products, they had a habit of "leaving" the Hardware at the BMUG presentations. Soon BMUG began to collect a massive amount of storage devices, printers and other devices, which added fuel to the frenzy of the BMUG community's fervor. In essence it spread like wildfire, as more and more companies began vying for the opportunity to show off their wares to spurn sales. In a symbiotic sense, BMUG became richer for it, as they could boast of having a serious amount of Hardware and Software when other outlets were paltry in comparison. Not to mention the incredible amount raw "Brainware" that was parlayed in the form of numerous famous and infamous guest speakers, which appeared and lectured at BMUG meetings.
Eventually this finally turned into the Hardware and Software vendor phenomenon that would become MacWorld.
BMUGnet/PhoneNET

One of the early successes for the group was BMUGNet, a variant of Apple's
LocalTalk system which used standard telephone wires to connect Macintosh computers together in a

. Wiring plans were initially published in the Fall 1985 BMUG Newsletter, but members could purchase adapters assembled by the group. Co-founder Reese Jones branched the production off as the commercial business
Farallon Computing in 1986, renaming the product
PhoneNet. The group invented other subsequent low-cost hardware kits as well... the 1991 introduction of the low-cost Mac LC prompted BMUG to begin offering a $12 VGA monitor adapter.

Controversy
Rivalry with the Boston Computer Society
BMUG was certainly the largest Macintosh users group, but the Boston Computer Society was the largest computer users group. BCS-Mac, the Macintosh special interest group of the Boston Computer Society, was the second largest Macintosh users group. A good-humored rivalry obtained between the two groups throughout their mutual existence, but they were ultimately supportive of each other.
BMUG's first foray onto BCS-Mac's Boston home turf, at
MacWorld Expo on August 11–13 of 1987 was commemorated with a new T-shirt, featuring an inscription "BMUG in Boston" which Bill Woodcock, who designed BMUG's T-shirts, intended to look like graffiti, using a rattle-can to write the original text in black paint on white paper, which was then photographed, scanned, and converted to PostScript in Adobe illustrator, before being silkscreened in red on black shirts. The red-on-black effect, however, was said by startled BCS-Mac members to more resemble dripping blood than spray-paint.
1995-1997 Budget Crisis
By 1995, BMUG had accumulated a debt of $250,000, which forced a two-year period of restructuring and the layoff of some of the staff, but which was weathered successfully.
Closure and Legacy

With the increasing cost of printing the biannual newsletter, decreasing membership and the waning sales of software due to the rise of the Internet, revenues could not keep up and the not-for-profit corporation declared bankruptcy in 2000. However, its members continued to collaborate and meet as separate entities in the following years.
* the San Francisco branch continued as BMUGWest until their closure in March 2016.
