在ACR1252U NFC读卡器上强制安装PC/SC驱动程序，并使用python进入卡仿真模式

Question

目标：让ACR1252U NFC读卡器在Mac上使用python进入卡仿真模式

使用PC/SC驱动程序在macOS Catalina 10.15.3上使用ACS ACR1252U读卡器时遇到问题。我从ACS website安装了驱动程序

通过使用pyscard（http://pyscard.sourceforge.net/）库，以下python代码在windows计算机上运行并返回正确的enter card仿真模式响应：Enter Card Emulation Mode Command & Response Format

import smartcard

hresult, hcontext = smartcard.scard.SCardEstablishContext( smartcard.scard.SCARD_SCOPE_USER )

hresult, readers = smartcard.scard.SCardListReaders( hcontext, [] )
print(readers)

hresult, hcard, dwActiveProtocol = smartcard.scard.SCardConnect(hcontext, readers[0], smartcard.scard.SCARD_SHARE_DIRECT, 0)

CTL_CODE = smartcard.scard.SCARD_CTL_CODE(3500)

apdu = [0xE0, 0x00, 0x00, 0x40, 0x03, 0x01, 0x00, 0x00]

hresult, response = smartcard.scard.SCardControl( hcard, CTL_CODE, apdu )

但它在Mac上给出了一个错误。我按照this的答案更改plist文件，但仍然得到相同的错误：

python3 nfc.py
['ACS ACR1252 1S CL Reader(1)', 'ACS ACR1252 1S CL Reader(2)']
Traceback (most recent call last):
  File "nfc.py", line 17, in <module>
    hresult, response = smartcard.scard.SCardControl( hcard, CTL_CODE, apdu )
  File "/usr/local/lib/python3.7/site-packages/smartcard/scard/scard.py", line 408, in SCardControl
    return _scard.SCardControl(hcard, dwControlCode, inbuffer)
SystemError: <built-in function SCardControl> returned NULL without setting an error

我使用自制软件安装了libnfc，但根据答案的第二部分，我不确定如何编译它

任何帮助都将不胜感激
