I downloaded FMS13 from the Technet area. I have not used FileMaker Server since 5.5 on a Linux server. Never having used it, I was able to install it successfully.
I am installing this on a mid2008 MacBook Pro running OSX 10.9.4. I upload one file. I wanted to try WebDirect. Under the STATUS I get NOT ENABLED. When I go into WebDirect is shows ENABLED.
I am not sure how to trouble shoot it. The installation did not "glitch" or hiccup at all.
