My dear Powermate is now completely dead. Plugging out and in doesn’t help It is strange that Griffin Technology hasn’t be able to fix the problem. They are aware of it, but no solution has been found as of yet. Obviously, there is no mention of the fact on their web site that it doesn’t work properly in 10.4. Maybe 10.4.3. will revive my Powermate.
