adb devices is not listing the devices

Question

adb devices is not listing the attached device instead the command hangs for ever. As per the suggestion given here in this SO answer killed the process which is running on port 5037 but after killing once it's listing the devices for me.

The next time when i enter adb devices the command hangs for ever. Any help in this regard would be much appreciated.

Additional information:

• Running this command on MacOS Mojave 10.14.6

It looks like there is some issue with the platform-tools which is installed in my machine. Downloaded the platform-tools given from this link

https://www.xda-developers.com/install-adb-windows-macos-linux/

And replaced ~/Library/Android/sdk/platform-tools with the downloaded one. It worked.
