I said, "Lightroom doesn't recognize camera when I want to import. The Apple Photo app sees the camera fine so it is a Lightroom problem. Mac OSX 10.11.3, Lightroom 3 Canon EOS 50D (Has imported thousands of photos to this system before)".
Adobe staff replied but I haven't had a respose to my queries after their reply
I was directed to:
You can try and reset the Lightroom preferences back to default.
The preferences file is the "com.adobe.Lightroom3.plist" file, located in [user name]/Library/Preferences, rename the file to "com.adobe.Lightroom3.plist.old"
Restart Lightroom and try using your camera with it.
Let us know if that helps.
I didn't find the file in question, although I did find .plist files fr other Adobe apps. I looked at backups dating before the upgrade to El Capitan, and the file was not present then either.
Today I updated my camera firmware to the latest version, compatible with Mac OS 10.11
What else can I try so I can import my photos to Lghtroom?
