XBee s2c configure as coordinator at

I am using X-CTU v6.3 in Mac OS X El Capitan

XBee S2C

In XCTU, the device is detected as
Function: ZIGBEE TH Reg
Product Family: XB24C
Firmware version: 4059

How do I configure it as a Coordinator at AT mode?

The update firmware button doesn’t show anything beyond the function and product family mentioned above.

You can do it on XCTU, open configuration of the device and you find many items there. Under “Networking” category find “CE coordinator Enable” which is “Disabled [0]” by default.Turn it “Enabled[1]” and save the configuration. That’s all.
Good luck!
