Update: Now with version 2.1 the process below changes slightly.

Blackmagic Design creates the world’s highest quality products for the feature film, post and broadcast industries including URSA cameras, DaVinci Resolve and ATEM switchers. Download BlackMagic Production Camera 4K Firmware Update Utility 2.0 for Mac OS (Digital Camera / Webcam / Camcorder).

The downloaded installer does not have an uninstaller like previous versions did. You'll need to run the uninstaller that came with the previous version.
Once you have installed 2.1 you will have an uninstaller app for 2.1 (on the Mac this is in the same folder as the 'Blackmagic Camera Setup' app). You can then run that before you install the next update (2.2, 2.3, etc) in the future.
To update your firmware you need to download and install the latest Camera Utility from Blackmagic.
You download it here:
https://www.blackmagicdesign.com/suppor .. al-cameras
Each update is self contained and includes all the previous updates. So you don't need to download each update. Just download the one you want (normally the latest version).
Once downloaded you will need to un-zip the file.
On the Mac you will then have a .dmg file. Double click on that to mount the disk image. Inside the mounted disk image you will find the installer, manual, documents and uninstaller.
On the PC you will then have a directory with the manuals and an installer file.
It's also advisable to run the uninstaller if you have a version already installed on your computer. Do this first.
Now you are ready to run the installer.
Follow the on screen prompts and read the Readme for any notes about the update.
This installs a few applications in your Applications directory. Now reboot the machine.
Once done, browse to your Applications directory and launch 'Blackmagic Camera Utility'
Connect the camera via USB (BMCC/BMPC4K USB port in the SSD bay, BMPCC USB port in the battery bay)
Turn the camera on. Make sure the camera is full charged (even better plug in the mains power supply)
The camera utility will now check the camera. If the firmware on the camera is different from the version installed on your computer (newer or older) it will tell you the camera needs updating. Click update and wait for it to complete.
The camera reboots once done and on the BMCC/BMPC4K the screen will flicker for a few minutes. This is normal and part of the process (as explained in the Readme, you read that part, right??).
Your camera is now 'up-to-date' with the version installed on you computer.
If you want to run an older version of the firmware simple download and install that version on you computer. The Camera Utility does not check the Internet for updates. You have to download a new Camera Utility for each update.
Again, It's also advisable to run the uninstaller if you have a version already installed on your computer.
