Rustyman Posted March 31, 2011 Share Posted March 31, 2011 When starting up my new Mackie Control in Logic, a message appears on the Mackie that a "Security Lock Failed", and it shuts down. What's up with this? Any solutions known? Quote Link to comment Share on other sites More sharing options...
Play Posted August 17, 2013 Share Posted August 17, 2013 Did you guys ever solve this issue? I have had a MCU Pro and a C4 Pro running beautifully... So I decided to buy an XT Pro. Got it today, cant get it to work, keep getting the "security unlock failed - shutting down" message when Logic starts. Not much info online about this either. Please give me some tips if you worked thru this. Thanks! Quote Link to comment Share on other sites More sharing options...
