EOS Utility won't install

creativere — Tue, 30 Jul 2024 13:07:31 GMT

I have a new MAC, M2 chip with 24GB Ram memory, running Sonoma 14.5 OS. I recently purchased an EOS R100 to start learning about photography. I am not able to install the EOS Utility 3.18.5, the installer just seems to cavitate at the "preparing to install". I have tried re-downloading more than a few times and attempted to install again. Same thing. I even tried older versions of the software. No luck. I was able to install the Picture Style Editor, Digital Photo Professional 4 with no issue. Just unable to install the utility. Ive tried with every application closed, and also logged into the Cannon website. Frustrated, want to view the photos on my MAC. Can anyone offer advice or help with this issue? Thx

At that point of the installation, a popup from macOS asks for your password to approve the software installation. It may have popped up under the application window. Try moving the app window around to see if you can see the password request. Here is a screenshot of mine:

Yes, the password window pops up and I enter my password, click ok, the window disappears, and I'm back to "preparing to install". I will stay like that for an hour or more not actually installing until I force close.

I should have confirmed - after you do that, it installs perfectly (PS, I'm on macOS 15 developer beta as well)

Sorry, no help, I'm still stuck at preparing to install after I enter my password

If I were you, I'd trash the file you have and re-download it from HERE.

Then, move the download to your desktop & install it from there.

I read in another forum to create a admin user account, log out of your Mac account on your laptop, log into the new admin account and try the install again, and it worked. I then logged out of the admin account and logged in with my original setup user account, deleted the admin account I created, and software still works.

It sounds frustrating! Try reaching out to Canon support for compatibility advice or consider using a card reader to transfer your photos directly to your Mac.

Hi, thank you so much for this post. I have been thrashing around for days trying to get this utility to install on both my Macs. Nether Canon or Apple Support had any clue as to what to do. I even reinstalled my OS and it made no difference. But the workaround you described above actually works, I have no idea why. But thanks again.

Mac OS Sequoia 15.6 can't install any Canon software using this installer. It comes down to dirty coding, while debugging and looking through the log report the issue is plain and simple. Canon developers have two instances trying to do the same function at the same time, they have both instances located in two different paths.

This will cause spurious casting failures and mysterious crashes. One of the duplicates must be removed or renamed.
