Mozy released a new version [v0.4.1.2 (19793)] of the Mac OS X client. It did resolve my problem of the Configuration Assistant not recognizing my account. As the reader, Marcus pointed out it was a permission problem that Mozy did not adhered to. Unfortunately, one problem solved and I am able to proceed a bit further in the Configuration Assistant, but now there is another problem where the Mozy client claims to be “Scanning Backup Sets…” and never finishes. I reported this to Mozy support.
Please see my original article "Problem with Mozy" for background.
