How to Offload a Phantom CineMag on a Mac with Apple Silicon

Phantom CineMag offload has long meant a Windows PC or an older Intel Mac on the cart. With MagDock you can review and copy CineMag takes on any Apple silicon Mac, natively, over the CineStation's 10GbE port.

What you need

• A Mac with Apple silicon (M1, M2, M3, M4 or later) running macOS 14 Sonoma or later.
• A Phantom CineStation with your CineMag inserted. MagDock is tested with a CineStation IV and a CineMag IV.
• A 10GbE connection: a Mac with a 10Gb Ethernet port, or a Thunderbolt 10GbE adapter, and a Cat6/Cat6a cable.
• A drive with enough free space. A CineMag IV 1TB can hold close to a terabyte of takes.

Step 1: Connect the CineStation

Cable the CineStation's 10GbE port directly to your Mac or 10G adapter and power it on. Open MagDock. It looks for the CineStation as soon as you plug in, even if the Mac's network port is on a different subnet from the CineStation's fixed address. If the network needs changing, MagDock offers to set up the Mac's port for you.

Step 2: Turn on fast mode (once)

The CineStation's fastest transfer arrives as raw Ethernet packets, and macOS only lets administrators read those. The first time, MagDock asks for your admin password and installs a small system script that grants admin users that access, the same approach Wireshark uses. After that it just works, about 350 MB/s, so a 40 GB 4K take copies in around two minutes.

Step 3: Review your takes

Every take on the CineMag is listed with a thumbnail, resolution, aspect ratio, frame rate, frame count, duration and trigger time. Double-click a take to play it straight from the CineMag, in slow motion at your chosen playback rate, with the camera's color and the anamorphic squeeze undone. Step frame by frame with the arrow keys to check focus or the moment of action before you copy anything.

Step 4: Offload to .cine

Select the keepers, choose a destination drive and click Download. MagDock checks there is enough free space first, never overwrites existing files and never leaves half-written clips behind if a transfer is interrupted. Files are written as raw 10-bit packed .cine with per-frame timestamps, exposure and the camera's image settings.

Troubleshooting

MagDock doesn't find the CineStation

Check that the cable goes to the CineStation's 10GbE port and that the adapter's link light is on. In System Settings → Network the 10G port should show as connected. Let MagDock configure the port when it asks.

Transfers are slow

Make sure fast mode is on and the link is negotiating 10 Gb/s, not 1 Gb/s. A short Cat6a cable straight to the Mac avoids most problems. The destination drive also needs to keep up: use a fast SSD or RAID.
