When the built-in SSD in his MacBook Air failed, Macworld’s Dan Moren decided to try replacing it himself (surprisingly, at the suggestion of an Apple Genius). The process was easier than he thought, taking only 20 minutes. He explains what he did, and walks you through how to restore your data with SuperDuper, including a pointer to a handy utility that restores Mac OS X’s Recovery Partition. follow link
ChronoSync Secret Menubar Shortcut
For a quick way to run a ChronoSync document without opening it, use the ChronoSync menu in the menubar. Select "Show ChronoSync menu in menubar" in ChronoSync's General Preferences window to activate the menu bar menu. Once activated, you'll see the ChronoSync circling arrows icon in the menu bar, at the top right of your screen.
You can open any scheduled ChronoSync document directly from the menu bar. If you hold down the Option key while selecting a ChronoSync document, the synchronization will run immediately without the ChronoSync document opening.
