Hi Experts, Finally, I have ordered used Macbook Pro 13" 2015 Model on eBay, hope it's in good condition/well maintained. So, I am being thought to switch to MAC OS for a long time as I fed up with Windows OS. I am being a Software Developer, I am very good at Unix and Linux systems and heard the mac OS is Unix based OS(correct me if am wrong). I need your valuable suggestions/recommendations how to start learning the MAC OS being Unix Person, whether it adds any advantage on learning? does mac OS has Terminal like Unix/Linux to run Unix-like commands and perform automation using shell script etc.,? Do I need to rely on GUI on Mac OS like windows or I can do many things in Terminal using Unix-like commands? What is the best to start with learning MAC OS? Please share your thoughts, it would be much helpful.
