Stairways Software has released version 5.3.1 of its Keyboard Maestro automation utility, which fixes an issue with executing Automator workflows in the upcoming release of OS X 10.8 Mountain Lion. This maintenance release also patches some memory leaks, resolves a performance issue with the Button Condition, provides Growl notification when a timeout cancels a macro, fixes a performance issue with getting the Finder’s selection, fixes the SECONDS() function, allows “APPLICATION” in the menu condition, and ensures that triple click actions perform correctly. The Mac App Store version of Keyboard Maestro 5.3.1 (not yet available as of this writing) now includes a fix that avoids “no autorelease pool” warnings when launching the engine. ($36 new from Stairways Software or the Mac App Store, free update, $25 upgrade from versions previous to 5.0, 17.7 MB, release notes)
Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
