Telestream has released ScreenFlow 4.5.2, which squashes a bug introduced in the previous maintenance release (see “ScreenFlow 4.5.1,” 28 May 2014) that prevented default export filenames from matching document names. The screencast recording app fixes a hang that occurred when opening documents with a high zoom factor, improves performance when opening documents with zoomed up timelines and many clips with audio waveforms, and fixes a memory leak related to modifying the speed of a clip with an audio waveform. For a complete rundown of the new features, read the PDF release notes from Telestream’s support page. Note that as of this writing, the Mac App Store version of ScreenFlow remains at version 4.5. ($99 new from the Telestream Web site or $99.99 from the Mac App Store, 39.1 MB, 10.7+)
Smarter Parental Controls
If you've been using the parental controls options in Mac OS X to lock your child out of using a particular computer late at night, but would like to employ a more clever technique to limit Internet access, turn to MAC address filtering on an Apple base station.
To do this, launch AirPort Utility, select your base station, and click Manual Setup. In the Access Control view, choose Time Access to turn on MAC filtering. You'll need to enter the MAC address of the particular computer, which (in 10.5 Leopard and 10.6 Snow Leopard) you can find in the Network System Preferences pane: click AirPort in the adapter list, and click Advanced. The AirPort ID is the MAC address.
