For 20-years I suffered Windows with several security issues and hack attacks. I cannot stand the slowness of booting windows. Mac is fast, more secure. Every time Windows updated something broke. My scanner stopped working (nobody could figure out why!) that works with the Mac now.
it is very simple. Use path of least resistance. For example NinjaTrader has tons of lower end things done for you out of the box. All you really need to focus is your model and execution. Unless you are HFT it will suffice for most. Algo trading is hard enough, my advice for you to not reinvent the wheel even if you personally do not like Windows or Linux.
