PKCS#11 Why i call C_GetSlotList return no slot with token presented for MacOS Application, and return one slot for Command Line Tool?

I face some troubles about PKCS#11 library. I create 2 projects:

• Project 1: macOS Application (GUI - with Objective-C)
• Project 2: Command line tool (Console - with C++)

unsigned long GetTokenInfos(CK_TOKEN_INFO_PTR pTokenInfo)
{
    CK_RV rv = CKR_OK;
    CK_ULONG ulCount = 0;
    CK_SLOT_ID_PTR pSlotList = NULL_PTR;

    rv = m_pToken->C_GetSlotList(TRUE, NULL_PTR, &ulCount);
    if(rv != CKR_OK){
        return rv;
    }
    if(ulCount <= 0){
        return CKR_TOKEN_NOT_PRESENT;
    }
    pSlotList = (CK_SLOT_ID_PTR)new CK_SLOT_ID [ulCount];
    rv = m_pToken->C_GetSlotList(TRUE, pSlotList, &ulCount);
    if((rv != CKR_OK) || (ulCount <= 0))
    {
        delete [] pSlotList;
        pSlotList = NULL_PTR;
        return CKR_TOKEN_NOT_PRESENT;
    }
    /*Get slot information for the first token*/
    for (unsigned int i = 0; i < ulCount; ++i)
    {
        rv = m_pToken->C_GetTokenInfo(pSlotList[i], pTokenInfo);
        if(rv != CKR_OK)
        {
            delete [] pSlotList;
            pSlotList = NULL_PTR;
            return rv;
        }
        //ShowTokenInfo(pTokenInfo);
    }
    delete [] pSlotList;
    pSlotList = NULL_PTR;
    return CKR_OK;
}

Both of them follow the same logic and flow of coding; build and run on a computer. But I got a strange thing: **Project macOS Application always return zero slot with HSM Token presented, on other side, project Command Line Tool always return one slot with token represented. **

I have no idea about the problem. I guess the macOS application project need some permissions or some things like that, in order to interact with hardware like HSM Token/ Smart Card...

Anyone had experience about the situation? Please give me some advice! Thank you all!
