Photographers thinking about switching from iPhoto to Aperture take note: Apple has released Aperture 3.1.2. In addition to improving the software’s overall stability and performance, the update addresses numerous issues with importing photographs from iPhoto — including at least one that could cause Aperture to crash. Various other importing issues are addressed, too. Also fixed are bugs with reference images, switching between libraries, hangs while using brushes, crashes with Retouch, and compatibility problems with XMP Sidecar files. Mac App Store purchasers should, of course, update the software via the store. ($79.99 in the Mac App Store, free update; 578 MB from the Mac App Store, 297.63 MB for the standalone updater from Apple’s Web site)
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.
