Firmware Update (Sony A7iii Camera) Apple Mac0S Users

Firmware Update (Sony A7iii Camera) Apple Mac0S Users

So you’re looking to update your Sony A7iii Camera with the latest firmware update.  Well Sony has made the process really difficult on Apple computer products, but if you follow the procedures below you should be able to update the camera.

The first Sony A7III firmware update (Firmware v1.01) has been released, to help fix a few camera stability issues.

The main fixes and benefits include

  • Blinking Pixels – Seems to only occur when camera is set to 25fps PAL format when shootingXAVC S 4K.
  • Touch Panel Unresponsive – A few people have had issues where the touch panel has become unresponsive.
  • Improves Overall Stability

Sony says that the new firmware helps to improve the overall stability of the Sony A7iii camera.

ILCE-7M3 System Software (Firmware) Update Ver.1.01
Resolves a “blinking pixels” phenomenon at the bottom edge of the image during XAVC S 4K (PAL 25p) recording (depending on the combination of camera settings)

Applicable Models
This information is for the following models: ILCE-7M3

The main issue has to do with Apple Macs that have the macOS 10.13 (High Sierra) software installed.  Apparently the Sony driver needed to update the camera doesn’t exist, so it needs to be added first.  Once that is done, you will need a second program known as the Sony System Software Updater.  The confusion is the fact that the driver has to be installed first and then the Sony System Software Updater can be run.  If you try to run the Sony system software updater first, things get all wonky.

IMPORTANT: For those Apple Mac users with the High Sierra Software installed, you will need to load some extra software called the “DriverLoader_1013”

For macOS 10.13 (High Sierra) Users

Currently the System Software Updater, software needed to update your Sony A7iii, does not support macOS 10.13 (High Sierra) without an additional driver called the “DriverLoader_1013”.

Note: If your operating system is macOS 10.12 (Pre High Sierra) or earlier, you don’t need to run “DriverLoader_1013” driver update.

Steps Needed To Update Sony A7iii Camera

  2. Download and run the System Software Updater
