I've update my Mac to 10.8.2 and, in the meantime, iPad to iOs6.
I've got the latest releases both of FMP12 and FMGO12.
From Filemaker Go 12 I can't see network hosts (that is my Mac).
I've tried disabling Mac firewall but nothing changed.
BTW, from the iPad I can't reach the Mac neither with Safari (trying to open the Mac with its IP address). This seems to be a network problem rather than a FM issue.
Anyone experiencing a similar issue?
