Hard to answer without specifications of that machines.
In general, You will need 8 GB RAM, nVidia GPU with 1 GB and minimal 2 cores CPU with highest available frequency. You can use lower specs, but FG will be compromited by visibility ranges, visual quality, low framerate etc.
Try to avoid AMD GPUs, they are troublemakers in FG.
Macs are overpriced, look for some gamers refurbished laptops.
I used FG on Dell Precission M4600 with i5 2 cores 2.5GHz CPU, 8 GB RAM and AMD 5950 FirePro GPU, that was reasonable config for decent low level flying with C172, or supersonic flights in very high altitudes and visibility 120 km with Concorde. For more realistic upper visibility more than 200 km You will need 32 GB RAM.
Fly high, fly fast - fly Concorde !
