Hi, I have issues while trying to connect bluetooth speakers to my imac.Connection to the master speaker alone is good. When connecting the 2nd speaker, connection becomes unstable.

However, connection to iphone, ipad & mac book is stable for both speakers. Any advice how to improve or my imac bluetooth is not correctly working?

For information, the speakers are supertooth latest generation & I have no software update pending.

Cheers and thanks for your advice & support.
