Weatherlink for Mac
Note that the Davis 6520 Weatherlink for Mac software does not implement all the features present in the
Weatherlink for Windows version. The Windows version outsells the Mac version by a considerable margin
and therefore traditionally Davis has focused its development effort on the Windows version.So please do
not assume that all features in the Windows version are present in the Mac version – they are not. If some
software feature is especially important to you for use with a Mac then this needs to be checked against the
Mac feature-list before buying and setting up the Mac version.
Weatherlink for Mac will not run after installation
Apple introduce updates for the OSX operating system at regular intervals and it’s not uncommon to find
that some aspect of the Weatherlink for Mac configuration needs tweaking before the WL software will run.
There are two issues in particular that may cause problems with more recent versions of OSX:
32-bit operation
Weatherlink for Mac must run as a 32-bit program. If your version of OSX is defaulting to running programs
in 64-bit mode then when you try to start WL you may see a java.lang.UnsatisfiedLinkError error or some
similar Java error. The fix is to set the WL application manually to run in 32-bit mode as follows (you should
only need to do this once):
• Look at your Desktop/Finder Screen.
• Open your Applications Folder.
• Open your Macintosh OSX Weatherlink Folder.
• Find, and select (click on once), the weatherlink, or, the weatherlink.app file.
• With weatherlink, or the weatherlink.app file selected, click the ‘More Info’ button in the preview pane
or do a Get Info command (from under the File Menu) – the exact steps will vary with the version of
OSX in use, but the objective is to display a dialogue that allows 32-bit operation to be selected.
• Put a check mark in the box marked “Open in 32-bit mode”. Then close the More Info/Get Info box.
• Now try to launch the weatherlink application.
Updated USB driver needed
An updated USB driver may be needed for recent versions of OSX to allow communication with the USB
logger. If the Weatherlink for Mac program can be launched but there is a communication error to the logger
then the chances are that a driver update is needed.
