How do I install GlowWorm FW Lite?
After downloading the GlowWorm disk image, double-click on the file to mount it (you don’t really allow your web-browser to automatically post-process “safe” files, do you?). A new window should appear, as depicted in the screenshot to the left. Drag the GlowWorm icon to the Applications alias icon immediately to its left. Take five. Get something to drink. Come back when you’ve caught your breath, and then run the program.
