Unless you are restoring from a backup, your Messages app is essentially a blank slate. Setting up a new Mac can be a mix of fun and tediousness. Long Exposure adds a DSLR-like effect for motion blur and Bounce lets you edit the action in your Live photos to play it forward and backward in a loop. Loop is Apple's answer to a GIF and lets you edit Live photos for the perfect repetitive loop. The Mac's native Photos app got a number of new features including the ability to edit Live photos with three new effects: Loop, Bounce and Long Exposure. Live photos still won't be GIFs, but High Sierra will help you make them act like one. For example, you can turn off autoplay videos for a site, but still let the site have access to your location and set a default page zoom level of your choosing. Specifically, Safari enables you to customize controls, settings and preferences for individual websites. Safari got a number of improvements, but the standout feature is the ability to block autoplay videos. Apple even announced ARkit, a new platform for developers to create augmented reality experiences for iOS devices. The new OS will support more powerful Mac hardware aimed at creative professionals, especially those creating VR and AR content. They include a packet sniffer and a real-time performance monitoring tool, just to give two examples of some of the tools that make this humble wireless channel scanner for Mac so useful.Apple finally gets into the virtual reality (VR) and augmented reality (AR) game with High Sierra.

But without a wireless channel scanner, proper WiFi channel planning is impossible because you have no way of knowing which channels are busy and which are free from traffic.
That’s why WiFi channel planning is so important, and why it should always precede every deployment of a WiFi network. While that may sound like a lot, only 3 of these channels are non-overlapping (1, 6, and 11), meaning they’re not affected by co-channel interference caused by adjacent channels. In North America, there are 11 channels available. WiFi networks (those that use the 2.4 GHz band) can also take advantage of multiple lines, or channels as they are called, when broadcasting data. That’s why busy highways tend to have multiple lines going both ways. When too many cars travel in the same line, the speed of traffic can slow down to a crawl and make traveling anything but enjoyable. Why? Because WiFi channels are sort of like the lines on the highway. It’s paramount that you pick a channel that isn’t already occupied by several other nearby wireless networks.
One available option lets you choose which WiFi channel the router should operate on. When you received your home router from your ISP, the chances are that you weren’t paying much attention to all configuration options available. Why Do I Need to Use a Wireless Channel Scanner?
