All users that purchased within the last two years are entitled to a free update, older than that will be $10 for diglloydTools or $20 for users that never acquired diglloydTools but did buy DiskTester long ago.
Although the existing version works fine with Mac OS X Lion, this update smooth out a few annoyances due to “sandboxing” that Lion introduced. There are also a few minor bug fixes for anything reported, but precious few bugs have been reported, so there is little to fix.
Although this version is technicaly a beta, I am not aware of any reason that it cannot be used as if a release version. Please report any glitches promptly.
All current (within the past 2 years) diglloydTools users have access to this beta download. Click through the license agreement to the download page.
