Apple’s 2015 Retina MacBooks see their first compatibility update for Multiport Adapters

If you were among those who bought a 2015 12-inch MacBook this past year, you probably had to buy an expensive accessory just to utilize a handful of ports that typically come standard with most laptops. For HDMI output and USB 3.0 input, you could have spent less than $45 on a third-party adapter from Amazon or upward of $75 on a similar product from Apple.

If you opted for the latter, the good news is that your USB-C Digital AV or VGA multiport adapter just received its first firmware update from Apple on Friday, promising to enhance the “compatibility and reliability” of accessories.

While your hard drive will only take a 205KB hit, there is a short list of steps you’ll need to take to prepare your Mac for the update, according to Apple:

1. This update requires OS X El Capitan v10.11.4. Use the Mac App Store or Software Update to get the most recent version of OS X.
2. Plug your USB-C Multiport Adapter into the USB-C port on your Mac. Make sure that your USB-C Charge Cable is connected to your adapter and plugged into a power source using your USB-C Power Adapter. 
3. Disconnect all external devices (such as displays, thumb drives, and hard drives) and hard-wired network connections from your USB-C Multiport Adapter.

With the adapter plugged in, a small updater notification in the upper right-hand corner of the display will appear, asking whether you want to install now or later. If you choose “Install,” you’ll have to endure a short updater process as shown in the image below, followed by a system restart, which prompts the actual update.

While it’s not clear specifically what this update was designed for aside from what was indicated, it could be another indicator that a second 12-inch Retina MacBook is on the way.

Last month, Apple’s System Image Utility and OS X Server applications revealed that a 2016 update to the lightweight notebooks could arrive by the end of April. By all accounts, this compatibility update to a MacBook-specific accessory could be a means of getting ready for that.
