Automate macOS Mojaves dark mode

In my opinion, the macOS Mojaves dark mode is one of the best features that Apple introduced for me. I work after hours a lot and the dark mode is awesome for that!
But I think Apple forgot to implement a automation or scheduler for that!

There is a freeware tool called NightOwl that can do the job. I just tested it and it works fine.
But in my workflow I need to do a bit more then just toggle the dark mode of macOS Mojave. Some Apps have the same (and many of then are still not so deeply integrated into macOS Mojave that they use the toggle).
So I came up with an poor mens approach that uses the macOS internal functionality (StartCalendarInterval with LaunchAgents)! to call a script that does all the thinks I want.

Issue with Skype for Business macOS with IPv6

A while ago my, Skype for Business Client on my Mac was unable to connect while I was in the Office. So I switched to our Guest Wifi and did some check (because it’s always the Firewall, and the guest network is nearly open – That is an insider, sorry!) and it just worked fine.

After joining our regular network again, the Client stopped working, on WiFi and Ethernet. The Firewall logs didn’t show anything useful. The Skype Logs itself pointed me to the right direction: Connection issues!

So I started to dig deeper and checked all the hosts Skype for Business tries to reach from the command line (Curl is your best friend in such cases). Tools like Wireshark could do the same job.

Microsoft Teams is now a complete meeting and calling solution

Last year we announced plans for Microsoft Teams to become the primary client for Intelligent Communications in Office 365, replacing Skype for Business Online over time. Today, we are pleased to announce we have completed our roadmap for bringing Skype for Business Online features and functionality into Teams, and Teams is ready to meet your messaging, meeting and calling needs.

The Article sounds great, and Microsoft Teams is a very good solution! But a few things are (still) missing!

PowerShell: Get the Office 365 Endpoint Information from Microsoft

A while ago, I published the reworked script to get Office 365 URLs and IP address ranges. Microsoft has built a new fully rest full Webservice to get the same information via JSON instead of XML.
The only drawback of the new service: If you like to use it for a single produce, you need to filter after you have downloaded the information. The product sets are limited.

However, there are a lot of examples in the new script, these examples show you how, where, and what to filter.
