numba parallel on mac, not working

import numba
print(numba.__version__)
numba.set_num_threads(4)
numba.config.NUMBA_NUM_THREADS = 4
import time

@numba.njit(parallel=True)
def f(n):
    s = 0
    for i in numba.prange(n):
        for j in range(n):
            for k in range(n):
                s += (i * k < j * j) - (i * k > j * j)
    return s


t1 = time.time()
f(5000)
t2 = time.time()
print(t2-t1)

my test code as above. numba==0.55.0 I have run on my mac, and linux

1. on mac, only use 1 cpu = 100%
2. on linux, can use 400%

how to use multi cpus on mac? thanks!
