How to configure 3G/4G dongle in macos 64bit version? I have faced this problem of not able to connect to 3G/4G dongles, currently the Huawei E3372 one. Was using Mobile Partner app &amp; since the 64bit upgrade it has failed.
I found a quick work around using the default "Network" option.
I am using Airtel 4G &amp; Huawei E3372 dongle.
Below are the steps followed:
 1. Open System Preferences > Network 


Configure adapter HuaweiMobile-
Configuration: Default
Telephone Number: *99#


In the Advanced pane:

Vendor: Generic Model: GPRS (GSM/3G)
APN: Default (check for APN through your provided for other services)
CID: 1


Select "Show Modem in status bar" for easy toggle.
