I will need to run a VM in order to use TradeStation desktopI had a top spec Intel Mac Pro for 3 years from work, it had almost constant fan on, horrible. I left that job and bought a Mac air for personal use. ARM Mac Airs are fanless and silent. Im not sure if the ARM Pros are fanless, but even if they have fans they probably not going to be anywhere near as hot as Intel Pros.
Unless you have good reason for an Intel mac like you need need to run Windows VM or some other specific software, i would not touch an Intel Mac these days.
