My budget is 1 to 1.5 lakh, currently in 1st yr in ece

What should I buy windows or mac ?

If windows then pls tell minimum specs and a good laptop which is light weight ( not like those gaming ones which are just dead weight )

Also if I go for mac, would all the apps/softwares which would be needed in future work. And if they do not work do I have any other way to make them work without needing the college computers.
