Headset Updater (Version 1.1.0 (2015), a Plantronics application.I can check for updates when I choose, not hundreds of times daily with SpokesUpdateService.
Realistically, Plantronics rarely updates the firmware or software for my headset. (No wonder my system died and refused to restart for hours!) I knew it was crashing my Late-2011 MBP with Sierra 10.12.6, but today's EtreCheck simple (free) 'diagnosis' show this damn SpokesUpdateService caused 113 crashes on November 3rd for me alone. For me, it seemed to launch around the same time each day. Please, forgive if I do not match this forum's etiquette. Though I regularly search for answers here, this is my first post.
