Mac OS X Server v10.6: Hosting Software Updates for OS X Lion or Lion Server

1. Update your server to Mac OS X Server v10.6.8.
2. Stop the Software Update service if it is running.
3. Quit Server Admin if it is active.
4. Update /etc/swupd/swupd.plist to begin hosting OS X Lion software updates. (See details below.)
5. Update /etc/swupd/swupd.conf to allow OS X Lion computers to receive updates. (See details below.)
6. Open Server Admin and start the Software Update service.
7. Use the instructions in Mac OS X Server v10.6: Using the Software Update service with multiple Mac OS X client versions to point your OS X Lion clients to this server.

In step 4, you will need root access to update the file /etc/swupd/swupd.plist. To be safe, make a backup copy of the file before editing it. Add the string in bold below to the otherCatalogs array:

    <key>otherCatalogs</key>
    <array>
        <string>index-leopard.merged-1.sucatalog</string>
        <string>index-leopard-snowleopard.merged-1.sucatalog</string>
        <string>index-lion-snowleopard-leopard.merged-1.sucatalog</string>
    </array>

Note: You can edit the file using a text or property list editor, or use the single command below to make the change.

sudo /usr/libexec/PlistBuddy -c 'add :otherCatalogs:2 string index-lion-snowleopard-leopard.merged-1.sucatalog' /etc/swupd/swupd.plist

In step 5, you will need root access to update the file /etc/swupd/swupd.conf. To be safe, make a backup copy of the file before editing it. Locate the following line near the end of the file:

    RewriteCond %{HTTP_USER_AGENT} Darwin/11

Edit the following line to read:

    RewriteRule ^/index\.sucatalog$ /index-lion-snowleopard-leopard.merged-1.sucatalog
