[macOS] add player detection

Notice the error Failed to detect memory

That was because sysctl vm.swapusage returned 0

vm.swapusage: total = 0.00M used = 0.00M free = 0.00M (encrypted)

which is an expected behavior because swap is dynamic allocated in macOS. In this case, using -1 as the error identifier should be a better option

Thanks for your work on this.
