This script declares the #!/bin/sh shebang and it will work fine on macOS with bash-as-sh.% shtest.sh still good However, when you try to run it with zsh-as-sh or dash-as-sh, it will fail. And my experience with a stolen computer was that even having Find My Mac enabled didn't help me get the computer back. The police would not use the location information to recover the computer. It is mostly for finding a lost computer or deleting your data so the thieves cannot gain access to your data.

You could also run one of the dyndns.org clients which updates the system's
address at their DNS servers. Then you just need to ssh into your-name.dyndns.org
or your own domain name if you so own one.
The client software periodically checks your ip address and makes an update to dyndns.org's system, all running quietly in the background as a startup process.
Of course, if someone were to steal your Mac OS X computer, wouldn't they need to do some pretty major reinstallation to get past your administrator password? Would this be likely to break any automatic system such as this that was installed?
I would think that an OS X theif would probably end up wiping the disk and reinsalling the OS before selling the system. But maybe they would boot it a few times and allow you to track it before it got wiped.

Setup crontab to email your ip address every hour:


1. At the terminal, type: sudo -s to become the root user.
   
2. Type your password.
   
3. At the root# prompt, type: pico /etc/sendip.ct
   
4. In pico, type the following: 0 * * * * /sbin/ifconfig -a | mail email@domain.com
   
5. Press ctrl x to exit.
   
6. Press y to save.
   
7. At the root# prompt, type: chmod 500 /etc/sendip.ct
   
8. To activate the cron job we just created, type: crontab /etc/sendip.ct
   

   To list the active crontab(s), at the terminal type: crontab -l
   {each user can have their own crontab(s)}
   To stop crontab, type: crontab -r
   

The problem with ifconfig is if you are behind a firewall it will return your local IP address.

Don't get fooled: if you read carefully the macphonehome FAQ's, you discover that the only protection against disk formatting is asking the user to set up an Apple Firmware Password to prevent boot from other drive...

If someone is smart enough to get around your account password (presumably by hacking root in single-user mode), they're certainly smart enough to change the IP address. And if they're not that smart, then they're just going to wipe the system with a new install, and therefore have an entirely new IP address anyway.

I'd think a better way of tracking your machine would be to keep track of the MAC address of your Ethernet or modem... Unfortunately, I'm not tech-savvy enough to know how to script such a tool. Some use of the 'ifconfig en0' command, perhaps? Just a thought.

The point of this IS to see what the ip has changed to, so you can track it down. What would be the point of keeping track of the MAC address? The MAC address never changes, well, unless you decide you want to change it to mess with your cable modem company or something.
In any case, you want two pieces of info, the actual ip of the machine, and the IP where it's coming from (like if it's behind a NAT device of some sort). I came up with an idea like this about 5 or 6 years ago, and I actually wrote a bunch of code for it (for windows). Alas, my hard drive with the code on it died, and I got a job that took up all my time so it never got finished. If anyone has a 3.8GB Quantum fireball w/ a good circuit board on it, I'll buy it from you. :)

Thank you for this. My ISP keeps changing my IP on me, almost daily. Makes it hard to login remotely. One problem I had with getting this to work was when I copied the text for the .netrc file, it put an extra return after each line with text. There cant be any blank lines between the lines of text or the macro wont work. In fact it will go into an semi-infinite loop and probably bug the server administrator of the ftp server you are connecting to.
The other problem I ran into was that the grep search wasnt finding the correct spot. I ended up changing:
grep –A 3 'Your IP Address is:' ~/scripts/sendIP/File1 > ~/scripts/sendIP/File2
to
grep –A 3 'Address is:' ~/scripts/sendIP/File1 > ~/scripts/sendIP/File2
