AP Grapher - forgetting SSIDs

AP Grapher for Apple OSX is a great utility for scanning for wireless points, SSIDs and, for your own base stations, what security they are running.

But after a while it accumulates lots of old stations. You can reset the list and have it forget them and start again by deleting or renaming the file

~/Library/Application Support/AP Grapher/basestations.plist.

Restart AP Grapher and it'll start from fresh
