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+)
Syslogd Overwhelming Your Computer?
If your Leopard (Mac OS X 10.5) system is unexpectedly sluggish, logging might be the culprit. Run Activity Monitor (Applications/Utilities/ folder), and click the CPU column twice to get it to show most to least activity. If syslogd is at the top of the list, there's a fix. Syslogd tracks informational messages produced by software and writes them to the asl.db, a file in your Unix /var/log/ directory. It's a known problem that syslogd can run amok. There's a fix: deleting the asl.db file.
Launch Terminal (from the same Utilities folder), and enter these commands exactly as written, entering your administrative password when prompted:
sudo launchctl stop com.apple.syslogd
sudo rm /var/log/asl.db
sudo launchctl start com.apple.syslogd
Your system should settle down to normal. For more information, follow the link.
