Can I use PureRef on macOS or Linux?

macOS: PureRef works on macOS 10.14 and newer versions (PureRef 1.11 also supports macOS 10.12). We made the choice to limit support for older versions mainly because PureRef uses the Qt framework and to stay up to date with that we have to follow their minimum requirements.

Linux: PureRef is verified to work on Ubuntu 16.04+ and CentOS 7, but should work on other distributions. GNOME and KDE are the DE's verified to have support for all features. Some DE's do not support transparency and some will insist on adding a frame to the window. If you are having these issues with your specific DE you are free to contact us and we will see what we can do but we can't promise we will add support for every distribution and DE.
How do I move the PureRef window?
PureRef 2.0 introduces a title bar that shows when the mouse is hovered over the top of the window that can be used to move the PureRef, its behavior can be configured under Settings > Appearance > Titlebar visibility.

Additionally, on Windows, right click and drag anywhere in the PureRef window. On Mac with a mouse, hold down the Control button, then click and drag anywhere in the PureRef window. On Mac with a trackpad, hold down two fingers, then click and drag anywhere in the PureRef window.
