Lightroom On Macbook Air 2016

New Member

I'm at my wits end and I cannot figure out what is going on. I am having trouble connecting my 645z to lighroom on my macbook air. When I start teather capture in lightroom it does not recognize the 645z and just says 'no camera connected' and on my camera it just says 'PcP' on the top screen. I have:
- updated my operating system to Sierra
- uninstalled and reinstalled the latest version of lighroom
- launched lightroom with factory default settings
- deleted and reinstalled the lightroom teather plugin and made sure it is enabled in ligtroom
- updated the firmware on my 645z
It has got to be something with my computer or lightroom setting or something is interfering with the lightroom plugin because I have the same version of lightroom and operating system on my desktop computer and using the same USB cable I can connect my 645z to my desktop and it recognizes the camera. Please any leads or tips or suggestions would be incredible helpful. Thank you.

Also one additional point of info - I was teathering just fine on my macbook air with my 645z and then one day it just stopped connecting. I just cannot figure out how to get it back connected. Its maddening.

Are you able to access the files on the camera via the finder? Also, I'd try another USB port just in case.

There are 2 things you can try if it turns out that you've got an issue with one or more ports on the MacBook. First, try resetting the NVRAM (nonvolatile random-access memory). You do this by holding down the following keys:
while restarting the computer. Hold them down until you hear a second set of the normal startup chimes and then let the MacBook finish restarting. Then try plugging your camera in again and try it out.
If it still doesn't work, try the procedure below:
The second option is to reset the System Management Controller (SMC) on the MacBook. To do this, perform the following sequence of steps:

1. Shut down your Mac.
2. Unplug the MagSafe or USB-C power adapter from your computer.
3. Using the built-in keyboard, press Shift-Control-Option on the left side of the keyboard, then press the power button at the same time. Hold these keys and the power button for 10 seconds.
4. Release all keys.
5. Reconnect the power adapter.
6. Press the power button again to turn on your Mac.

There's no guarantee that either of these will work for your problem, but they've been known to fix port issues by resetting the ports. I've used them successfully on my MacPro for similar problems, although the exact sequence of steps for resetting the SMC is different. Never needed to use them on my MacBook Pro, however.
Hope this helps.
