Setting a Static IP Address on Mac

A couple of weeks ago, I provided you with instructions on how to set a static IP address on Windows computers. This post will show you how to do the same thing on a Mac. You'll want to do this if your time clock clients fail to connect to the time clock server after the computer is rebooted. It's probably getting a dynamic IP address from the router which causes it to sometimes get a different address the next time the computer is turned on. That's why your time clock software works perfectly for months until you get hit with a power outage, or someone turns off the computer.

Here are the instructions for assigning a static IP address on Mac computers.

Go to the Apple menu, choose System Preferences and select Network from the Internet & Wireless row. Select your network interface from the list on the left (probably the one with the green status indicator). Change it from Using DHCP to Using DHCP with manual address so it should still get all the Internet stuff it needs automatically. It'll look something like this when you're all done:

​When you give a static IP address to a computer, the router may not know that address is being used so it may try to give it to another computer later. So you'll want to give your computer an IP address that's not likely to be given out to others.
