Trouble finding EOS Utility for macOS to use Mac as monitor for EOS Rebel T3i

markf32000 — Tue, 10 Mar 2026 20:05:29 GMT

Hello, I am trying to use my old macbook early 2011 with El Capitan version 10.11.6 as a monitor for my Rebel t3i. I downloaded the utility it recommended and when I try to install it doesn't install. It says "Extracting Files" and then nothing happens. So then I tried to find utility 2.13 but all it has on the canon website is a 2.14 updater.

Is there a way to download the original utility software online or something similar, and/or how can I get this to work with my camera and old mac?

Thanks!

Is what you download a file ending in ".dmg"? If so, that's a "disk image" that should have opened an item on your Desktop. It's possible that you have your Finder Settings/Preferences not set up. Make sure you have the following options set:

Show these items on the desktop

[X] Hard disks

[X] External disks

[X] CDs, DVDs, and iPods

Good thought. I checked though and they are all checked. It is a .dmg.

Still nothing after extraction files.

It should have still placed an item on your Desktop. You may have to find it and double-click it to open up its own Finder window. That should then show you the contents of the dmg. Or are you staying that the window that opened for the dmg is empty?

From downloads I double click the file from the canon website and then it opens the canon window to double click an icon to start the download. Then it says "extracting files" and after it does that nothing happens. I tried t look for another window somewhere but I can't seem to find anything.

I'm not sure what is going on unfortunately. What you could try is the following:

On Canon's web site, make note of the .dmg file name (e.g. something.dmg)
After the downloading is done, in Finder, press Command-F
That should bring up a Finder window with the Search field active
Enter in something.dmg (whatever the file name actually is), and that should reveal where that file is.

Thanks for the help. Still not working, must be something with the old macbook. I have an old HP laptop I'm going to try today and see if I can get it to work on there.

Try downloading 2.14 from the El capitan page of the support site.

Are there any disk access permissions you need to authorize?
