Rogue Amoeba has released version 2.1.4 of its Fission audio editor, adding full support for OS X 10.9 Mavericks and moving to the 64-bit frontier for future performance gains. The update replaces the QuickTime engine for opening files with Rogue’s own internal libav for handling multimedia, which may not support some “extremely rare” file formats. The saving pipeline has been revamped, which improves how the Mac App Store version saves ringtones. The new version also improves its handling of extra-large AAC and Apple Lossless files, slims down the debugging window, and makes it possible to drag an iTunes song into the Mac App Store version with a single attempt.

Single Time Machine Backups
Tired of Time Machine running all the time? You can turn it off in the Time Machine preference pane, but still initiate a single backup by choosing Back Up Now from Time Machine's menu bar icon. Of course, your backup is much less likely to be up to date, but Time Machine won't be taking any resources while you're trying to work.
