Hello all, I started my MDD DUAL 1.25 MHz / 2 GB RAM / 120 GB and 200 GB HD / NETSCAPE 7.2 / OS X.4.11 and the following dialog box popped up. The system extension “/System/Library/Extensions/symfs.kext” was installed improperly and cannot be used. Please try reinstalling it. I shut down properly and was away from my computer for about a day. Suggestions Dan Currie
