Peter Lewis of Stairways Software has released Keyboard Maestro 6.4.1, updating the essential automation utility with a number of bug fixes — there are no feature changes. The update fixes potential crashes when undoing Execute AppleScript actions, creating custom icons, and processing text tokens; prevents time triggers from executing twice due to timer drift; addresses a bug that could partially cancel actions that followed an Exit From Loop; and more.

Wake On Demand in Snow Leopard
Putting your Mac to sleep saves power, but it also disrupts using your Mac as a file server, among other purposes. Wake on Demand in Snow Leopard works in conjunction with an Apple base station to continue announcing Bonjour services that the sleeping computer offers.
While the requirements for this feature are complex, eligible users can toggle this feature in the Energy Saver preference pane. It's labeled Wake on Network Access for computers that can be roused either via Wi-Fi or Ethernet; Wake on Ethernet Network Access or Wake on AirPort Network Access for wired- or wireless-only machines, respectively. Uncheck the box to disable this feature.
