Keyman Sinhala for Mac OS - Can't download the keyboard

I am using OSX ver 10.11.6 and when I try to download new keyboard the window doesn’t show up anything. Please help.

Yes, this is a known issue that we are working on resolving. In the meantime, there is a workaround:

  1. Visit the website directly (I’ve pasted in a link for Sinhala keyboards).
  2. Download the .kmp package file for the keyboard you wish to use.
  3. Drag the .kmp package file into the Keyman Configuration window to install it.
