This morning i saw that CU4 was released for Skype for Business Server, i knew from the MAC client release there was a new CU coming very soon for Skype for Business and Lync Server 2013. I don’t see anything for Lync Server 2013 yet though. But it seems there a new CU for Skype for Business Server CU4 6.0.9319.272
When looking over the improvements and fixes i don’t see anything related to the MAC client specifically but i do this mentioned “This update enables Location-Based Routing to support the Skype for Business mobile clients” as the MAC client is really a mobile client perhaps this resolves the issues with E911 support for the MAC client. Nothing mentioned about removing the dependency of a reverse proxy for the MAC client and having mobility deployed. Ill have to do some testing i think.
Whilst reading about the Mac client CU1 update i stumbled across this, which seems to suggest the dependency on mobility is removed for SfB Server and Lync Server 2013 with the latest CUs.
Without Skype for Business Server 2015 CU4 (build 9319.272 or higher, now available) or Lync Server 2013 CU8 HF1 (build 8309.973 or higher, now available), Skype for Business on Mac requires Mobility enablement on the server side. After updating to builds 9317.272 or 8309.973, Mobility enablement will no longer be required.

Improvements and fixes in the November 2016 update
This update enables Location-Based Routing to support the Skype for Business mobile clients. It also fixes the following issues:
|Fix and Improvement||Symptom / Cause|
Assume that a Microsoft Skype for Business Server 2015 server is experiencing high latency. In this situation, when you dial into a conference, you experience long periods of silence. This is caused by the latency on file I/O operations to the server.
||Typically, this issue occurs in a large Microsoft Skype for Business Server 2015 environment.
This issue occurs because a certain task hits an exception that delays regular messages processing or leads to intermittent "503 Service Unavailable" error on Persistent Chat servers.
||Assume that you set the EnableClientMusicOnHold parameter to false in a Microsoft Skype for Business Server 2015 client policy. When you use a Microsoft Lync Phone Edition telephone, you cannot put a call on hold.|
||Assume that you apply a normalization rule to the address book, and then restart the Front End server of Microsoft Skype for Business Server 2015. In this situation, the RTCSrv.exe service crashes.|
Consider the following scenario:
In this scenario, Japanese characters in the subject line of the missed call notification email message are garbled.
There seems to be quite a few components are require updating with CU4
