Dear Support,


I got a freeze issue.

Every I connect my MacBook with OS 10.5.8 to gateway router, my Mac just freeze.

I've try to use Wireshark to capture some packet and found the freeze always happen on it received an IGMPv3 member query packet.

Could you help to clarification it?


Best Regards,

    Hi, this has worked for a few...


    Make a New Location, Using network locations in Mac OS X ...




    10.5, 10.6, 10.7 & 10.8…


    System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.



    10.5.x/10.6.x/10.7.x/10.8.x instructions...


    System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.


    The interface that connects to the Internet should be dragged to the top of the list.


    If using Wifi/Airport...


    Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.


    For 10.5/10.6/10.7/10.8, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...



    (There may be better or faster DNS numbers in your area, but these should be a good test).

    Click OK.

    Dear BDAqua


    My MacBook has get the IP from Gateway correctly.

    However, my MacBook got freezing after it received a IGMPv3 member query from Gateway. e.g. Terminate & Safari & Wireshark no response.

    I think my network configuration of Mac is correctly, but most application of Mac just no response.

    When this problem appear, I can't even shut down my Mac or use Terminate to ping somewhere.

    Please let me know if any question, thanks!


    Best Regards,

    Just update the status.

    After my Mac receive the IGMPv3 member query, it will reply a IGMPv3 membership report.

    But the Wireshark is already freeze and not able to show the report packet.

    I use the other PC to capture it.

    To find out if it's system wide or user specific, try this...


    Open System Preferences>Accounts, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.


    Does it work in the new account?

    I'm sorry, but the freeze issue still happen on new account.

    Hmmm, is IPv6 enabled or disabled?

  • David.Li Level 1 Level 1

    In my environment, the Gateway Router use IPv4 only.

    And my Mac is default configuration, it should get IP from DHCP server automatically.

    So I think the IPv6 is disable.
