Smile has updated both PDFpen and PDFpenPro to version 5.8.5 to add compatibility with OS X 10.8 Mountain Lion. Additionally, both releases fix an issue with scanning when running 10.7 Lion, as well as an issue where resampling at a lower resolution produced a larger saved file. Both updates are rounded out by other unnamed minor fixes and improvements. ($59.95/$99.95 new with a 20-percent discount for TidBITS members, free update, 40.7/41 MB)
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.
