Sony released a7S III Firmware Update 1.02 which fixes FTP Transfer and USB Tethering stability along with improved overall camera stability. For Mac users, I highly recommend updating now as this update will probably not be compatible with MacOS 11.
Benefits and Improvements
• Fixes an issue where FTP transfer could fail when used with some USB-LAN conversion adapters
Note: Not all USB-LAN conversion adaptors are guaranteed to operate properly
• Improves connection stability of USB tethering when using an iPhone
Notes: Currently, the USB tethering function does not support iOS 14
We recommend using a smartphone and USB cable that support USB-PD (USB Power Delivery)
• Improves the overall stability of the camera
