Heimdall on OS X High Sierra/ Mojave

Samsung Galaxy devices use Odin to flash firmware, however Odin is only available on Windows unfortunately.

Heimdall is a cross-platform open-source tool suite used to flash firmware (aka ROMs) onto Samsung Galaxy devices from Benjamin Dobell, an alternative for Odin on Linux/Mac.

Packaged Heimdall binary from link doesn't work on High Sierra or latter, so you will have to compile source code from gitlab. Heimdall frontend requires Xcode 9.4 above.

bfabiszewski @bfabiszewski has merge request: Fix build on macOS High Sierra for Heimdall, which replaces three CMakeLists.txt files from source. Without these fixes, cmake step from Benjamin Dobell will fail.

I followed fix from bfabiszewski on OS X  Mojave and built Heimdall binary successfully.

It seems that best practice is to run Heimdall with sudo, and also for heimdall front end. One caveat or feature I noticed is that Heimdall tends to release kernel drive after some operations, which might cause next task failed with initialization error. If this happen, just disconnect/reconnect usb cable, and run heimdall detect to make sure Heimdall can detect Samsung Galaxy devices.
