You join an online meeting by using the Skype for Business Web App or Lync Web App on macOS High Sierra 10.13 (including beta versions).
Someone in the online meeting shares their desktop.
Macos Screen Sharing App
Oct 06, 2017 Pro tip: By default, only administrators are allowed to share the screen on Mac, you being the administrator will have that right. But if you want users with a guest account to also be able to share the screen, on the bottom right-hand side of the sharing folder there are radio buttons with the text “allow access for:” the switch it to all users from only these users. Sep 26, 2018 Microsoft Lync Web App (macOS High Sierra) - Black Screen When Sharing I am running the Microsoft Lync Web App version 15.8.6 on a Mac that is running macOS High Sierra version 10.13.6 and cannot view other users content being shared with me. If you’ve been given permission, you can view and control the screen of another Mac on your network. On the Mac you want to share, choose Apple menu System Preferences, click Sharing, select Screen Sharing, then note the name and address of the Mac (it’s listed on the right). The name looks like “iMac (7)” or “Joe’s MacBook Pro.”.

Mac Os Screen Sharing App
Several types of sharing exist in macOS Sierra All are found in (where else?) the Sharing System Preferences pane, which you can find by launching the System Preferences application and clicking the Sharing icon.
Screen Sharing
Screen Sharing lets you control another Mac on your network from your Mac. In essence, you see the other Mac’s screen on your Mac — and control it using your mouse and keyboard.
To set up Screen Sharing on the Mac you want to control remotely, follow these steps:
Macos Screen Sharing Port
Open the Sharing System Preferences pane by launching the System Preferences application and clicking the Sharing icon.
Select the check box for Screen Sharing in the list of services on the left.
Select either the All Users or Only These Users radio button.
If you opt for Only These Users, click the + (plus sign) button and add the user or users you want to allow to control this Mac remotely. Notice that the Staff group is included by default.
360 editing software for mac. To take control of your Mac from another Mac, follow these steps:
Click the now-you-see-it-now-you-don’t Show tag to the right of Shared to open the Shared section in the Sidebar, if it’s not already open.
Click the name of the remote Mac you want to control.
Click the Share Screen button.
Depending on whether you selected the All Users or Only These Users radio button, you may have to enter your name and password, and then click the Connect button.
A window with the name of the remote Mac in its title bar appears. In it, you see the screen of the Mac you’re looking to control remotely.
Go ahead and click something.
Pull down a menu or open a folder. Isn’t that cool? You’re controlling a Mac across the room or in another room with your mouse and keyboard!
Internet Sharing
Macos Sierra App Store Link
If your Mac has an Internet connection and another Mac nearby doesn’t, you can enable Internet Sharing, and the other Mac can share your Internet connection. The following steps show you how:
Open the Sharing System Preferences pane by launching the System Preferences application and clicking the Sharing icon.
Select the Internet Sharing check box in the list of services on the left.
Choose the connection you want to share — Wi-Fi, Bluetooth, FireWire, Ethernet, or Thunderbolt — from the Share Your Connection From pop-up menu.
Select the check boxes next to connections other computers will use: Wi-Fi, Ethernet, or Built-In FireWire.
(Optional) Click the Wi-Fi Options button to name, select a wireless channel for, enable encryption for, and/or set a password for your shared network.
That’s all there is to it.
And yet more ways to share
A few more cool ways to share your Mac include
Macos Sierra Screen Sharing Application
DVD or CD Sharing: When you select this one, remote users can access CDs and DVDs in your Mac’s optical drive(s). You can select to have Sierra notify you and request permission when a remote user makes such a request. This feature is especially handy if you have two or more Macs, and one doesn’t have an optical drive.
Printer Sharing: If you turn on Printer Sharing in the Sharing System Preferences pane, other people on your LAN can use any printer connected to your computer.
Scanner Sharing: Analogous to Printer Sharing, Scanner Sharing allows others on your local network to use scanners connected to your Mac.
Bluetooth Sharing: If you have a Bluetooth mobile phone or PDA and your Mac has Bluetooth, you can configure many of the default behaviors for transferring files to and from your Mac. A picture is worth a thousand words.
