Modifying the OSX IP Stack on the Client
Before running a 3.2.x or later release of the Mac FSD, you must edit the /etc/sysctl.conf file on
your Mac FSD client as follows:
1. Open the /etc/sysctl.conf file on the Mac FSD client. If the /etc/sysctl.conf file doesn't exist on
your Mac FSD client you may need to create one.
2. Add the following settings:
net.inet.tcp.delayed_ack=0
3. Restart the Mac FSD client for the change to take effect.
4. Verify the settings as follows:
a. Open a terminal window, and enter the following:
$ cat /etc/sysctl.conf
b. Verify that the file shows the following settings:
net.inet.tcp.delayed_ack=0
If it does not show the setting above, continue to the next step.
