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.

Although DiskDoubler and SuperDisk! both serve the same function, how they approach the task differs. When you compress a DiskDoubler file, you'll know it's compressed right away - the icon for the document or application that you just compressed turns into a DiskDoubler iconShow full article

Program Speed
