    On my MBP I usually see under "Shared Devices" in Finder another MAC.

    Wouldnt that mean that theres another mac using my Wi Fi ??
    How do I go about blocking it ???

    Just log into your router and see what devices are connected.. Check the MAC address of your devices to what's listed in dhcp on the router

    Yea done that but couldnt narrow it down... there are loads of devices connected...

    I was wondering could I delete it off finder even ???

    There are about 12 devices connected to router... the mac addresses of the connected devices dont correspond with the mac in finder ???

    Restart your Mac. Mine is usually quite slow at releasing machines that have connected before.

    Are there that many devices in your home ? Download LanScan and see how many devices are actually on your network. Restarting the router may clear any arp caching going on. Might also be worth changing the WPA Key in case someone else has managed to get the password.

    Also change the admin password on the router, it's amazing the number of routers I see still using the default Admin Username and Password, those in the know can easily determine the make of a device simply by reading the MAC address to discover the make, e.g. TP Link or Netgear, for which there is usually a default password of "admin".
