3 In simple terms, this lets you have a simple human-readable address to connect to instead of an IP address-rather than remembering 123.45.678.9, you use something like. (The trick then is remembering which port goes to which Mac.)ĭynamic DNS: I wrote a piece years ago about setting up Dynamic DNS for your home machine. Just forward a different one to port 5900 of the local IP of each of the Macs you want to connect to remotely. 2 Fortunately, there are plenty of unused ports nearby, so I just increment and use 5901, 5902, etc. The default port for screen sharing (or VNC, if you prefer) is 5900. Port forwarding: Because I’ve got multiple Macs on my local network, I need to specify a different external port for each computer that I connect to. Conveniently, that’s also the tab you’ll need to use for port forwarding.
If you’re using an AirPort Extreme/Express or a Time Capsule, you can set this up using the DHCP Reservation option on the Network tab in AirPort Utility. Local IPs: It’s generally easier if your home Mac (or Macs) always has the same IP on your local network.Now, this does take a little preparation, but the good news it that once you invest the initial time to configure it, you shouldn’t need to do it again. There are a number of ways to do this-configuring an SFTP server, for example, or using Back to My Mac 1-but the one I’ve found most handy is using OS X’s built-in Screen Sharing. I keep most of my smaller files in Dropbox or iCloud Drive, but on occasion I need to grab something like, say, a podcast MP3. However, that also means I frequently run into situations where I need to retrieve a file from my home iMac that I don’t have handy on my MacBook. Working at home all the time can make even the hardiest soul a bit stir crazy, so I like to leave the house most days, just to mix it up a bit. Note: This story has not been updated since 2015.
