Description (partial)

Intermittent poor video quality during video calls.

Client is running and user is signed in. User makes or receives a video call. Cisco Jabber has an algorithm that determines if the hardware is suitable for high definition video, while this algorithm works fine on all other platforms and on most Mac models, we have identified that on a limited number of Mac models the algorithm tends to give low values resulting in lower resolutions as Cisco Jabber thinks the hardware won't be able to handle high definition video when in actual fact it would.

To verify if this is causing low resolution and bad quality video calls:
1. Open the Console application
2. On the left panel navigate to ~/Library/Logs then find Jabber and select the first jabber.log file 
3. On the top-right Filter field type "cpuScore is"
4. If there are no results try on the remaining Cisco Jabber logs (jabber.log.1, jabber.log.2, jabber.log.3, jabber.log.4) 
5. If there are no results on either of the log files then make a video call and repeat steps 2 and 3

If the result of your cpuScore is bellow 115 then you might be affected by this issue.
