Rebuild a Volume Directory

  • The tool replaces the corrupt directory with a newly created directory. It takes the backup of the old directory and mounts the Mac volume in the new directory, which makes all your seemingly lost data accessible.

Verify Disk Permissions

  • You can verify disk permissions with various apple-originated files and folders present on all bootable volumes in the system containing any OS X.

Repair Permissions

  • This option is used if a volume with the operating system has developed permission issues with the files installed by the Mac OS X installer. It comes with an option "Repair Permission module", which checks if there are any problems with disk permissions granted to different users and identifies any issue with them and gives an option to repair them in case of any discrepancy.

Create Bootable DVD

  • Volume Repair provides you an option to create a bootable DVD to repair the boot volume of your Mac. You can select your boot disk to boot your system and fix your boot volume. However, if your Mac is not bootable, you can create bootable DVD on another system of similar configuration. This bootable DVD can then be used to boot your Mac and rebuild the corrupt volume directory.

Easy-to-use-Interface

  • The rich GUI makes the overall process very easy and quick to perform. The interface also provides an option to rollback and update.
