Finally I get it work on Mac OS X 10.6 Snow Leopard.
I have an USB broadband modem which came with the broadband subscription, is a Huawei E160. Unfortunately the software came with the modem, doesn't work in Mac OS X 10.6 Snow Leopard.
You need to download the latest software from Huawei support here, select Download - Software, choose Software - For Mac OS X 10.6 on the left.
There are 3 software available:
1. Dashboard installer.
This is the installer but it doesn't include the Mobile Partner software.
2. Mobile Connect driverThis driver works with OS X 10.6.
3. Huawei UMTS Dashboard
This is the Mobile Partner software.
Step 1: Install the Mobile Connect driver
You may need to reboot if you are replacing the old driver.
You can check for the old driver exist before install the new driver. The driver will be located at:
Mac HD/Library/Modem Scripts/HUAWEI Mobile Connect - 3G Modem
Step 2 (optional): Dashboard
Is a software to help you to install the Mobile Connect software. You need Mobile Partner software mounted before install this software.
Step 3: Install Mobile Partner software (Huawei UMTS Dashboard)
You may already have a Mobile Partner, then you don't need to install.
The old software call Mobile Partner, the newer Mobile Connect software is written in Java. The new software response a bit slow, just be patient.
