Support Notice

Apple OS version 10.5.6 is not supported by Facilis Technology on older Mac Pro workstations that use the Expansion Slot utility. The ATTO Celerity card normally in a x4 slot will default to a x1 slot and cause problems with fibre channel communication. 

Until further notice, the workaround for this problem is to revert the workstation back to 10.5.5.

Thank you.
