Platform specific installation

2. Download mac package

3. Unzip the file

4. cd into the folder

5. ./Nethermind.Launcher

6. Select desired configuration

RocksDB library does not always load properly on macOS. One (hacky) workaround is to install the latest version of RocksDB by running brew install rocksdb. For the time being it should not cause much trouble but the future RocksDB versions may be incompatible. See other Known Issues here.
