How do I send or receive a le via iChat when the Mac OSX rewall is
active? -for Macintosh users- Mac OS X 10.2 and later
“iChat cannot send or receive a le when the Mac OS X rewall is active in its default
state. If you have opened the AIM port, you may be able to receive a le but not send
them.
In its default state, the Mac OS X rewall blocks le transfers using iChat or America
Online AIM software. If either the sender or receiver has turned on the Mac OS X re-
wall, the transfer may be blocked.
The simplest workaround is to temporarily turn off the rewall in the Sharing preference
pane on both computers. This is required for the sender. However, the receiver may
keep the rewall on if the AIM port is open. To open the AIM port:
If you do not want to turn off the rewall at the sending computer, a different le sharing
service may be used instead of iChat. The types of le sharing available in Mac OS X
are outlined in technical document 106461, “Mac OS X: File Sharing” in the AppleCare
Knowledge base online.
Note: If you use a le sharing service when the rewall is turned on, be sure to click
the Firewall tab and select the service you have chosen in the “Allow” list. If you do not
do this, the rewall will also block the le sharing service. “
The following information is from the online Macintosh AppleCare knowledge base:
Step 1 Choose Apple menu > System Preferences.
Step 2 Choose View > Sharing.
Step 3 Click the Firewall tab.
Step 4 Click New.
Step 5 Choose AOL IM from the Port Name pop-up menu. The number
5190 should already be lled in for you.
Step 6 Click OK.
