std/os/index.zig: use "hw.logicalcpu" instead of "hw.ncpu" in macOS; (#1317)
Tracking Issue #1252 ;
hw.ncpu was deprecated in macOS. Among 4 new options available (hw.{physicalcpu, physicalcpu_max, logicalcpu, logicalcpu_max}), hw.logicalcpu was chosen because it actually reflects the number of logical cores the OS sees.1 files changed, 1 insertions(+), 1 deletions(-)
