[original message]

Dear customers using Mac OS,
In a few weeks a new version of Mac OS will be released (Mac OS 10.8 Mountain Lion).
Caldera V9 doesn’t support this new version.
YOU ABSOLUTELY MUST NOT UPDATE THE CURRENT CALDERA INSTALLATIONS TO THIS NEW VERSION, otherwise the Caldera software will become inoperative.
The Caldera DVD will refuse to be installed on the new version.
You will have to erase the disk to come back to a previous version of Mac OS for it to be reinstalled.
Rest assured that we are making every effort to release as quickly as possible a new version of the Caldera DVD that can be installed on Mac OS 10.8.
Thank you for your understanding,
The Caldera development team
