RRavindr you could try a "fresh install" - that sometimes fixes strange issues like this.

To "uninstall" previous LTspice: 

• Delete the /Applications/LTspice.app folder 
• Delete the  ~/Library/Application Support/LTspice folder 
• Delete any LTspice directories in ~/Documents 
• Restart for good measure 

To install the latest version of LTspice:

• Download latest LTspice from https://www.analog.com/ltspice  
• Install LTspice by double-clicking download file and dragging the application into the applications folder
