First tweet i read this morning from Randy Chapman was the news that i think all Mac users have been waiting a long time for. There is a Skype for Business Mac Client!!!! Thanks Randy for the heads up as always. I had a mac for a years but i don’t use it alot to be honest im mainly a windows fan and use my mac once in a while. Thought spent i little time collecting some information into a blog post on the mac client and sharing my install of the client and a quick look around.

Also Iain Smith (MVP) talks about the Mac client in the Skype show episode 10 Microsoft client Download link Points to Note before you download the client. System requirements for your MAC to use Skype for Business • OSX 10.11 (El Capitan) or OSX 10.12 (Sierra) • Outlook Mac build 15.27 (161010) required for Outlook integration Office 365 and Lync / Skype for Business Server topology Microsoft are recommending to get the latest and greatest to move to Skype for Business Online but that not an option for everyone. For on premise bad boys Looks like there will be new CUs for SfB Server and Lync Server to remove requirement for mobility to be deployed and also to support E911.

• Skype for Business Server 2015 or Lync Server 2013 • Skype for Business Server 2015 customers should at a minimum download and install the Skype for Business Server 2015 Cumulative Update version 9319.272 or higher (coming soon) • Lync Server 2013 Cumulative Update version 8308.973 or higher (coming soon) • Unfortunately Lync 2010 Server – Lync Server 2010 is not supported – There users will have continue to use the Lync for Mac 2011 client. Mobility Requirement and Enablement The Mac client works like a mobile client so you need mobility enabled but I also noticed the below so it looks like there will be a number CU released soon for SfB server and Lync Server which allows the Mac client to work without mobility being enabled. This is a major dependency.

• E-911 support requires Skype for Business Server 2015 CU4 (build 9319.272 or higher, coming soon) or Lync Server 2013 CU8 HF1 (build 8309.973 or higher, coming soon). • Without Skype for Business Server 2015 CU4 (build 9319.272 or higher, coming soon) or Lync Server 2013 CU8 HF1 (build 8309.973 or higher, coming soon), 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. Features and Functionality The Mac client still doesn’t have the same level of features as the Windows based client unfortunately. This i can only see being worked on on future releases. I think Mac users will be very happy to have a new client but still feel they are a little behind with feature set.
