Error on exported gpg secret key from linux to Mac [duplicate]

Question

I have exported a gpg key from linux to Mac. Exporting commands on linux are as follows

gpg --export-secret-keys -a test_01.asc
gpg --export -a test_01_pub.asc

Importing commands on Mac are as follows

gpg --import test_01.asc
gpg --import test_01_pub.asc

But when decrypting with the imported key,

gpg -d -vvv test_01.gpg

gpg said

gpg: using character set 'utf-8'
gpg: enabled compatibility flags:
# off=0 ctb=85 tag=1 hlen=3 plen=268
:pubkey enc packet: version 3, algo 1, keyid XXXXXXXXXXXXXXXX
        data: [2048 bits]
gpg: public key is XXXXXXXXXXXXXXXX
# off=271 ctb=d2 tag=18 hlen=2 plen=62 new-ctb
:encrypted data packet:
        length: 62
        mdc_method: 2
gpg: using subkey XXXXXXXXXXXXXXXX instead of primary key XXXXXXXXXXXXXXXX
gpg: encrypted with rsa2048 key, ID XXXXXXXXXXXXXXXX, created xxxx-xx-xx
      "xxx <xxx@xxx.com>"
gpg: public key decryption failed: Bad secret key
gpg: decryption failed: Bad secret key

And when I tried to change its passwd

gpg -vvv --edit-key XXXXXXXXXXXXXXXX
passwd

gpg said

gpg: key XXXXXXXXXXXXXXXX/XXXXXXXXXXXXXXXX: error getting keyinfo from agent: System error w/o errno
gpg: key XXXXXXXXXXXXXXXX/XXXXXXXXXXXXXXXX: error getting keyinfo from agent: System error w/o errno
Key has only stub or on-card key items - no passphrase to change.

The versions of gpgs on Linux and Mac are 2.2.41 and 2.4.0

Thanks for the explaining. The problem has been solved. After regenerating a new dir ~/.gnupg and configing the pinentry-mac for pin entrying, the key importing process prompts for passwd and the key is imported successed.
