Yam Display for macOS High Sierra.

Extend Display by AirPlay® for macOS High Sierra (10.13.4 ~ 10.13.6)
Yam Display uses AirPlay® to extend display for macOS High Sierra (10.13.4 ~ 10.13.6) due to an issue. There can be issues for older Macs (released before 2011) that do not support AirPlay mirroring. Resolutions are limited to horizontal ones. The issue was resolved in macOS Mojave in which full screen resolutions including portrait mode were restored.

What macOS versions does Yam Display support?

Yam Display supports from OS X Mavericks (10.9) to macOS Catalina (10.15).
Yam Air supports from OS X Yosemite (10.10) to macOS Catalina (10.15).

For macOS Sierra prior to 10.12.2, Yam Display/Air has following issues:

  • Some apps can be displayed in black in Yam Display.
  • Forced log out when using some features of Mission Control.

These issues can be fixed by updating macOS Sierra to the latest version (10.12.2 or later).

For macOS High Sierra, please check this FAQ: Yam Display for macOS High Sierra.
