The TS4 has two 3.5mm audio output connections — one combo port on entrance that may help headsets with built-in microphones, and one output-only port on the rear — however the entrance combo port takes precedence.

Noteworthy enhancements

The CalDigit TS4 enhancements transcend simply having extra ports than the TS3 Plus, as you’ll discover enhancements made to the beforehand present ports. For instance, all the dock’s USB ports — together with the USB-A ports — are 10Gbps connections.

Whereas we’re on the subject of energy, CalDigit has made it in order that solely two of the 4 rear USB-A ports provide energy whereas not related to a number machine. That is useful for gadgets that you simply don’t wish to obtain powered whereas not related to your Mac.

Twin 4K or 6K show connectivity

The CalDigit TS4 can join accommodate a wide range of show output configurations based mostly on the kind of gadgets you intend to attach.

Whereas this received’t lend entry to Thunderbolt solely peripherals, resembling Thunderbolt SSDs, it’ll permit customers to interface with different gadgets related to the dock. For instance, this is useful when utilizing a USB-C iPad Air or iPad mini.

9to5Mac’s Take

CalDigit’s TS4 could look just like the TS3 Plus, nevertheless it’s a big improve over its predecessor. It offers wider compatibility with each Thunderbolt and USB-C hosts, options two downstream Thunderbolt ports as a substitute of only one, options quicker Ethernet connectivity, and is appropriate with a number of 6K shows and even an 8K show when related to correctly configured Home windows machines.

There’s just a few downsides that I can consider with this dock. First is the value, as a result of at $360 it falls properly outdoors of impulse purchase territory. And as talked about earlier than, the dock can’t cost a 16-inch M1 Professional/Max MacBook Professional at full pace, however that’s merely Thunderbolt limitation. The dock additionally contains a pretty big exterior energy provide, though because of the bigger kind issue of the TS4, it doesn’t look as massive as earlier than. One final thing — I want you would toggle off the white LED on entrance of the dock. It’s simple to miss within the daytime, however may be an annoyance in a darkish atmosphere.

However these complaints are pretty minor when in comparison with the design and performance of the CalDigit TS4, which incorporates every little thing however the kitchen sink. I really feel like I’m repeating myself right here, however once more, in the event you’re searching for the perfect all-around dock on your Mac, the CalDigit TS4, which is now available on Amazon, will get my advice.
