I backed up and copied the original file, "sysctl", using the terminal command
sudo cp /usr/sbin/sysctl /usr/sbin/sysctl.real
Then opened the copy (the original is now called "sysctl.real") in
BB Edit, deleted its contents and replaced them, using BB Edit, with
#!/bin/sh
echo "PowerMac11,2"
and then saved the file. Made this "new" sysctl an executable with
sudo chmod +x /usr/sbin/sysctl
then ran the X1900 installer.
After the install, I got rid of the copy and put the original back, using the terminal
sudo mv /usr/sbin/sysctl.real /usr/sbin/sysctl
BB
P.S. Normally, "sysctl" and its directories are invisible. You may need a utility such as
Deeper to make them visible. Also, I left the prompt, "$", out of the terminal commands as this appears in the terminal and will screw things up if you copy here and enter it into the terminal.
P.P.S Made
bold the terminal commands for clarity.
