Formatting Your USB Drive For Your TeslaCam, on macOS High Sierra and Catalina

As a Tesla Model 3 owner, and macOS user, I’ve seen lots of threads on how to format your external drive for your TeslaCam, on Windows, or even older versions of macOS, but following those instructions, it has been driving me nuts that certain times my car detects the new drive, but most times it has a grayed out cam icon on the top right.

Well, I’ve figured it out, after some playing around, and here are the instructions.


I am running macOS Catalina, and my external USB drive is a Seagate 2TB external storage. This should work with High Sierra, Sierra, or Catalina.

  1. Stick your external drive in your MacBook.

  2. Open Disk Utility.

3. In Disk Utility, make sure you select View -> Show All Devices as you won’t be able to partition your drive otherwise. It took me a while to figure that out, and I was wondering why my external drive Partition option was grayed out.

4. Select your external drive (the upmost object, in my case Seagate BUP Sim…).

5. Click on Partition.

Make sure when partitioning, if your drive is set to scheme Master Boot, change that to GUID Partition Map. This is very important, to allowing your car to recognize your drive.

6. Open your drive in Finder, and create a new folder, TeslaCam.

And that’s it, you should be able to have your TeslaCam up and running! Let me know how you go.
