The company, who makes a variety of Thunderbolt 3 peripherals, discovered that their devices will not work with the new MacBook because they use a first generation controller chip from Texas Instruments.
Apple has chosen to prevent Thunderbolt 3 devices using currently available controller chips from Texas Instruments from enumerating and functioning on the 2016 MacBook Pros. All current Thunderbolt 3 peripherals which use this controller chip are incompatible with the new 2016 Thunderbolt 3 MacBooks (To our knowledge, this includes all currently available Thunderbolt 3 devices including our TBT3-DP2X and TBT3-HDMI2X graphics adapters. Our Thunderbolt 3 cables do not require this chip, and therefore are compatible.)
Because of this, we've made the difficult decision to postpone our TBT3-UD1 Docking Station as we evaluate what is necessary to make this docking station MacBook-compatible. Our Flagship TBT3-UDV dock with Power Delivery/Charging is using the next generation controller chip from TI, and will be compatible with the 2016 Thunderbolt 3 MacBooks.
Plugable expands on its findings in a statement provided to MacRumors...
The version of OS X on the new MacBook Pros (late 2016) will not work with existing Certified Thunderbolt 3 docks and adapters (released prior to November 2016). These existing devices use Intel’s Thunderbolt 3 chipset (Alpine Ridge) in combination with the first generation of TI USB-C chipset (TPS65982).
Apple requires the 2nd generation TPS65983 chipset for peripherals to be compatible. Certification of solutions across different device types is still in-progress for this 2nd generation chipset. From the Plugable product line, our dual display graphics adapters for DisplayPort and HDMI (TBT3-DP2X and TBT3-HDMI2X) are affected and are disabled by OS X on the new MacBooks. So we offer these products as Windows-only Thunderbolt 3 devices until a future hardware update. Our Thunderbolt 3 cables do not require this chip, and therefore are compatible.
We’ve also made the difficult decision to postpone our TBT3-UD1 Docking Station to update to the TPS65983 chipset and re-certify to make this docking station MacBook-compatible. Our Flagship TBT3-UDV dock with Power Delivery/Charging was already planned to use the next generation controller chip from TI, and will be compatible with the 2016 Thunderbolt 3 MacBooks.
Apple issued the following statement on the matter to AppleInsider:
"While we have no comment on Plugable's specific complaint, products using the newest Thunderbolt chipsets, with up-to-date drivers, will have no difficulty connecting to any 2016 MacBook Pro"
The revelation is bound to cause further upset among pro users. Many feel as though the company's laptop is no longer 'pro'.
