Can you get MAC drivers for Huawei U8180?
You do not need drivers for a Mac. 

What you can do so you can access adb from anywhere is create an environment variable that
points to the path of adb.


Open Terminal
Type cd ~ this will take you to your home directory  
Type touch .profile this will create a hidden file named profile  
Type open -e .profile this will open the file you just created in TextEdit
In the file, type export PATH=${PATH}:/pathToTheAndroidSdkFolder/android-sdk-mac_86/platform-tools
Save file, close TextEdit, Quit Terminal, and Relaunch Terminal


now when you run adb devices, in a terminal, you should see something like the following:


  List of devices attached
  5751A45CB25EF device


if you don't see anything listed for devices, make sure you have USB Debugging enabled in Settings > Development > USB Debugging
