Mac Utilities on Leopard

Whenever there is major Mac OS upgrade, i.e Mac OS 10.5, Leopard, one must be very careful using third party disk utilities. There are many behind-the-scenes changes to the way the OS works and the third party companies must update their software to keep up.

  • Apple's version of TechTool Deluxe has been updated and is available for download here
  • Disk Warrior is now shipping version 4.2 which works on Leopard and they promise to have an updater available for download soon.
  • Drive Genius 2 was just released today and, according to the press release, is fully Leopard compatible. It is a paid upgrade.

Even Apple's own Disk Utility can cause problems when used with incompatible systems. Due to changes in the way permissions work in Leopard, repairing permissions from Tiger on a Leopard Startup Disk will cause problems and probably render the disk unbootable.

Always make sure any utility can alter the hard drive is compatible with your system.
