10.15.2 has broken tethered capture

16-inch Macbook Pro


10.15.1 tethered capture with Canon 5DMK4 bodies worked fine with C1Pro 20 and 12 as well as Canon EOS Utility.


After 10.15.2 update EOS utility just hangs and crashes and C1Pro cannot access cameras for tethered shooting. Tested and confirmed broke with Canon and Fuji bodies.


uninstalled/reinstalled C1pro and EOS utility.


MacBook Pro 16", macOS 10.15

After about 2 hours at phone with Apple Support Italy here the results:


We have created a new Administator Account on my MacBook Pro and magically everything returns to life, tether my A7rIII works with every app installed (Sony Remote, C1Pro 20, Lightroom 9.1, Darktable). So Apple Support tell me that maybe there's something wrong with permission in my account.


So we turn back to my account and tried to reset permission with this procedure:

then I restarted my Macbook. 

C1Pro 20 and Darktable finally see my Sony and now I can work again  


The only one app that doesn't work yet is Sony Remote, but this is another mistery.

32-Bit Only App Compatibility is the Issue:

The issue is that this program is 32-bit only. It is incompatible with 64-bit-only operating systems (10.14 and thereafter). Learn More at this Site: EOS Utility 3.8.20 for Mac OS X - Canon Support. It reads, compatibility:

  • 10.10
  • 10.11
  • 10.12
  • 10.13


At this Point, Either...

  • use this with High Sierra, or...
  • await a new driver and firmware update to be provided by Canon.


If this were, me I would: just create a New Partition for High Sierra, or use it on my older Mac. Installing it from...

This is not a 32bit app compatibility issue.


First, EOS Utility and tethering in other apps worked in Catalina 10.15.1 that was already 64bit only, and second, it's not an EOS Utility problem because in Wi-Fi mode it's working (very slowly, but it works...), and the problem is the same in Lightroom or CaptureOne, with Canon, Sony, Fuji and other cameras, with no EOS Utility or special drivers needed to work in these apps...


This is only a macOS native driver problem, and hope that Apple will quickly solve this problem.

I can also confirm on my Canon EOS 100D it now works again. Amateur, compared to most of the professionals in this discussion.

I have to say, sadly, I did not expect any word from Apple: that would have been admitting how big they’re scr**ing things up lately.

Backing up now, making sure I have a time machine recovery point to go back to, should something similar happen again.
