i created a second user on my mac, [mac v10.13.1 (17B1003)]
and i had them both run BM simultaneusly....
while having that, my mac started having rare freezes [that freezed the mouse as well],
sometimes for few sec', sometimes like a minute,
until one freeze was so long [over an hour] that i decided to restart the mac....
there was nothing on the system logz btw.
after the restart, i didn't open the other user again,
at first it seemed to solve that bizarre issue,
but after 3 days, i had another freeze for 2 seconds,
and that really made me start panic, had no idea what could cause this....
i also started having a cable issue w my current headset,
so i decided to change the headset, to one that also had build in mic,
anyway i started looking into the system sound settings,
and thats when interacting w the system sounds volume bar acted weird,
and then it reproduce the freeze, in a bit of a repetitive way....
i remembered some ppl complained BM made driver issues,
and my friend told me these freezes are probably drivers issues,
didn't think twice, closed BM.
had to reconnect the headset so weird slowing and the sound coming from the mic will disappear, and now i think its gone, tho, not much time passed....
