This program helps you clean up your Sandbox.
Some QuickTime components are incompatible with OS X sandboxing, which leads to problems – including crashes – with many popular video and photo apps.SandboxCleaner finds and reveals those components, helping you to fix the problems and keep your system up and running smoothly.
If SandboxCleaner detects one of the components known to cause problems, it helps you figure out what to do.
