Phillip Garding I went through the current installation experience on the Mac platform with a standard user, and was prompted for admin rights. I thought this requirement was already removed?
For others' benefit, here are the steps needed to install Skype for Business on Mac (12 clicks, versus 6 with the Meetings App).
1. Click the link to download the file. (downloading direct because the new experience is not yet available)
2. Open your Downloads (varies depending on browser) and locate the Skype package, and run it.
3. At the Skype for Business Installer screen, click Continue.
4. At the Software License Terms screen, click Continue.
5. At the Agree to the Terms screen, click Agree.
6. At the "This will take 115 MB of space" screen, click Install.
7. Prompt for admin rights. Enter administrative credentials and click Install Software.
8. At the "Installer" wants access to control "System Events" screen, click OK.
9. At the "Installation was successful" screen, click Close.
10. At the "Do you want to move the "Skype for Business" installer to the Trash screen, click "Move to Trash".
The software automatically launches Microsoft AutoUpdate.
11. (If Auto-Update is launched), click Install to install the latest update.
12. Click the link for the Skype for Business meeting again (again, can't quite test this experience yet).
13. After the software launches, type your name and click Join as Guest.
14. If prompted for microphone access, click OK.
