Solution to "device not detected" for ckb-next on MacOS Big Sur

1. Reboot into Recovery mode and disable SIP(hold cmd + r when booting until a grey screen flash)

   csrutil disable
   

2. Normal boot, a popup should prompt for allow loading kext
3. Reboot into recovery mode and add kext team ID into whitelist

   spctl kext-consent add G43BCU2T37
