UVLayout runs under the X11 environment, but X11 is no longer bundled with the OS X operating system. You can however get the latest version of X11/XQuartz from ...

http://xquartz.macosforge.org

We recommend before you install UVLayout that you run X11/XQuartz first, to make sure that it is working OK, and enable the "Focus Follows Mouse" preference (see image right). This only affects applications run through the X11 environment, which is most likely only going to be UVLayout, so don't worry about any adverse effects.

To install UVLayout, open the supplied UVLayout.dmg disk image file and follow the instructions in the Read-Me.txt file.

If this is the first time you have installed UVLayout, you will need to activate it by cut'n'pasting your license key into the keys file. Instructions on that are here.

Known Problems

• If you launch UVLayout and nothing appears to happen, check if you have your display configured for dual monitors, but only one is plugged in or turned on. If you turn on the second screen and find UVLayout there, you can drag it back to the main screen and "pin" it with the top left most button in the UVLayout GUI.

• If you launch UVLayout and the "Starting UVLayout" dialog appears, but nothing happens after that, try starting X11/XQuartz first and then launch UVLayout. If that doesn't help, reboot your Mac to kill any zombie processes that might be interfering with UVLayout's normal start-up procedure.

• If your whole screen goes gray after launching UVLayout, it means that X11 is running in full screen mode. You can toggle this with Cmd-Opt-A, and then go to the X11 preferences to turn it off permanently.

• Very poor drawing performance. See the OpenGL preference.
