I've tried everything I can think of. I just can't get my Xbox 360 to see my mini. Program starts and authorizes my 360. Firewall is turned off. iTunes and iPhoto is shared out. My 360 just will not see the Mac. Both are connected via a Dlink 624 router. Mini is wireless . Xbox 360 is hard-wired. I've even tried switching the mini to the wired ethernet. No luck. Need some help.
