Hi people,


I was in Console investigating another issue, when I saw this message popping up every 4 seconds:


01/07/12 01.54.18,000 kernel: com_oxsemi_UserClient::start()

01/07/12 01.54.22,000 kernel: com_oxsemi_UserClient::start()

01/07/12 01.54.26,000 kernel: com_oxsemi_UserClient::start()

01/07/12 01.54.30,000 kernel: com_oxsemi_UserClient::start()

01/07/12 01.54.34,000 kernel: com_oxsemi_UserClient::start()



Google has not been of any help, so you guys are my last hope    Any ideas what this means, the cause, or how to fix?

MacBook Pro 15, Mac OS X (10.7)

    Something to do with an Oxford Semiconductor device, I'd guess. Try disconnecting all external storage devices and see whether it goes away. If not, boot in safe mode.

    If it doesn't happen again, and you're not having problems with the drive, I wouldn't worry about it. Log messages aren't significant in themselves. They're only meaningful in relation to a usability problem.

    I had two disks connected over Firewire (on a Retina MacBook Pro via the 27 thunderbolt screen). This message dissappeared when I disconnected them.


    I narrowed it down to being caused by my "Lacie Rugged Safe 1TB" firewire drive. Removing it was the solution. I didn't like this device anyway. You can't disable hardware encryption on it so you're forced to install their software instead of simply relying on the much simpler builtin encryption that OSX offers.
