From the developer:
nRF Connect is a cross-platform tool that enables testing and development with Bluetooth low energy (previously called Bluetooth Smart). The tool allows for an easy setup of connections with other devices. You can use these connections for reading and writing to the external nodes.
nRF Connect is designed to be used in conjunction with the nRF51 DK, the nRF51 Dongle, or the nRF52 DK running a specific connectivity application.
You may want to check out more Mac applications, such as nrf-ble-sniffer-osx, Desktop Connect or NumPad Connector, which might be related to nRF Connect.
