软件介绍
As long as plugSHIELD is running, no one can plug and copy anything from your Mac.
Remember how in the movie Iron Man, Stark's girlfriend managed to steal all of the bad guy's data with a flash drive? You may not be up to villainous deeds, but you probably still want your files safe and secure from any potential thieves.
While activated, plugSHIELD will shut down any plug & mount attempts from USB, firewire, memory card and other ports. Your mac will refuse to accept portable devices plugged into it, be it a USB flash drive, an SD card, or a firewire removable hard disk.
Also, as a bonus, you may give your iPod or other device a real quite power charge without iTunes pop out. The device will be power charged only and can be freely plugged or unplugged at anytime.
