How can I tether my Sony a5000 to my MacBook Pro?

Tethering your camera is supported by both Sony Camera Remote Control and Capture One Pro but Live View is not.

DigiCamControl http://digicamcontrol.com/ claims to support Live View with your model.

Every Mac ships with an application called Image Capture. It's in your Applications folder. It tethers to a lot of cameras. Give it a try. Free and it works great.

EDIT: Live view is available for free through darktable on macOS. The refresh rate is low and the picture quality is poor but it is a live view nonetheless! For those struggling, sometimes other processes hijack the connection to the camera so I tried killing processes in Activity Monitor and successfully got a connection to darktable.

Live view is provided through gphoto2, which has a list of supported cameras.

At the time of writing this, Sony has updated their software to Imaging Edge. This supports the A5000 (ICLE-5000) but does not provide a live-view option.

Testing with my A5100 it works over USB and does have a nice set of options.

Using the mobile app Sony PlayMemories on my iPhone, I can get live view for the A5100, but the refresh rate is at around 1 Hz.

This is an old thread, but the A5000 can be used as a "webcam" using the OpenMemories-Tweak from ma1co on GitHub.

I've successfully used this procedure (modified slightly since I used the macos version of pmca-gui) to output clean (ie: no on-screen displays) 1080p from the micro HDMI port. I use a $15 USB 3.0 HDMI video capture device and have used it with Google Meet, the macos Photo Booth app, and OBS.

I've noticed the cheap capture card has a slight lag, but that's about it.
