Lion Compatibility

TechTool Pro 6 is now compatible with Mac OS X 10.7.x (Lion) from version 6.0.3

TechTool Pro 6, versions 6.0.2 and earlier will show a warning that TechTool Pro 6 has not been tested with Lion. Using these versions may produce unexpected results. These are the known issues of version 6.0.2 at this time when used with Mac OS X 10.7.x:

• Video Memory Test is non-functional, and may crash the app.
• eDrive: Cannot select a volume which contains Mac OS X 10.7. This is by design to avoid problems with new versions of the operating system.
• Volume Cloning: Duplicate Cloning doesn't work.
