Drag and drop programming support
This J-Link OB model optionally supports the drag & drop programming feature. For more information about host OS specifics, potential limitations, ... please refer to the drag and drop programming wiki article.
Drag and drop fails under macOS Ventura
Starting with macOS Ventura, file download via drag & drop could fail with macOS error code 100093. This was caused by a change in behavior of macOS, introduced with that version.
Fixed in J-Link OB firmware that comes with J-Link software V7.82b and later.
