can't import picture from my samsung galaxy s2 to my mac mini

Your problem, hardware or software, may not be exactly the same as that of the original poster of this older thread, and it can be very confusing for everybody if we try to answer more than one question in each thread, which can also result in you applying the wrong advice to your particular problem.

In order for us to give your problem our proper attention to try to solve it, would you kindly start your own thread, describing the trouble you are having in the fullest detail, including completing your details to show what Mac or iDevice you are using, what operating system, and what version of the application in question. Please remember to post in the forum relevant to your hardware or version of OS X. A full list of all the support forums is here:

Does Image Capture see the phone?

You might also try Bluetooth File Exchange. see > https://support.apple.com/en-us/HT201820

I don't have a Samsung GS2, but I have no problems using Bluetooth File Exchange with other Bluetooth Devices including my lame-o Motorola flip phone. It's not elegant, but it works.

Today I downloaded a new version of Kies, 3.1.0.15042_6, and it seemed to work fine. I was able to backup my Note 3 running Lollipop with no hesitation. Files transferred to my Mac running Yosemite, OS X 10.10.3, easily. The download is available at http://www.samsung.com/us/kies/

On my iMac, 2012, through a USB hub, running the Kies version I listed, it worked fine. I wasn't using a particularly good USB cable either. I do have "Firewall: Off" in my "Security & Privacy" panel in "System Preferences" if that could have anything to do with it. (Yes, I do have other security software, and I turn off my WiFi when not using it) My Note 3 isn't the newest hardware.

I do remember one tip that was given in one of the blogs I read when searching for ways to make it work previously. I had to go to the "Settings" and select the "General" tab and then choose the "Developer options" menu option. Scrolling down to the "USB debugging" section, I clicked the check box. The description reads, "Debugging mode launches when USB is connected." I'm not sure that this made the difference, but I have always had it checked when it has worked for me. This is in Android 5.0, Lollipop.

Apologies for the double post.

I don't know what image capture is. When I plug my Galaxy 2 into my macbook USB port nothing happens.
