You might have to download Huawei Stick mobile partner software for Mac 10.11 El Capitan before you can get your Huawei e303 dongle to work on your Macbook running Mac OS El Capitan.
When my Glo bolt e303 modem didn’t work on my Macbook pro, I downloaded the software and since then, I’ve been using the Glo modem to connect to the internet.
How To Download Huawei Mobile Partner Software for Mac OS
If you want to download the software for your Mac, follow through the steps below:
Enter e303 in the search bar at the top right hand corner of the site and hit the ‘enter” key on your keyboard
or just click here to go directly to the Huawei download page for e303 dongle.
When a new page opens, scroll down till you get to the section where you can download the software as highlighted below: “Stick Mobile Partner (for Mac10.11)”
Click on the “Download now” icon to download it.
Once the download completes, you can double-click it on your mac (to unzip it) and install it accordingly.
I hope this helps.
If you encounter any problem, kindly let me know via comments.
If you are using an old Mac OS, you can upgrade to ElCapitan MacOS.
You can also download mobile partner software for Mac OS 10.9 Mavericks, 10.10 Yosemite and Mac OS 10.12 from Huawei website.
