Simple really, I use Adobe Bridge to import all my photos, how do I stop iPhoto automatically searching my sd and iPhone for pictures? I have searched the preferences and also searched the preferences in El Capitains' dashboard. If it was a Windows computer I'd alter how the commuter reacts when media is inserted, but try as I can I cannot find the solution just by searching. I suppose a regedit, or a suitable terminal code could do it..?
To help we need accurate details
You discuss EL Captain and iPhoto and autodownload and you posted in the iPhoto for Mac forum
What are you using (iPhoto or Photos)? What version?
What is the autodownload - there are several - MyPhotoStream, PhotoStreams, iCloud Photo Library, etc
The way to stop it depends on what yu have and what exactly you want to stop

Open iPhoto and go to it's General preference pane. There set the "Connecting camera opens" setting to No application.

If the Photos.app is automatically launching, when you insert a card, uncheck the box "Open Photos for this device" in the Photos Import panel.
It will stop Photos from launching, until you format the card to erase it.
A quick and dirty solution would be to disable the launch of any application at all: Right now you can only try to disable the autolaunch of any photo application altogether. But it does not always work and any update might break it.
This Terminal command will disable the auto start of any photo application, not just Photos. So Lightroom will not launch either and you will have to launch the application of your choice manually.

Restart the Mac . it should not be necessary, but it only worked for me after restarting.
I found this fix in a post by JadedEye (to léonie)
