While Apple has always fully implemented Thunderbolt standards, PC/Windows makers had optionality with what parts and features would be present on a Thunderbolt 3 system. As a bidirectional adapter, it can also connect new Thunderbolt 3 devices to a Mac with a Thunderbolt or Thunderbolt 2. The Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter lets you connect Thunderbolt and Thunderbolt 2 devices such as external hard drives and Thunderbolt docks to any of the Thunderbolt 3 (USB-C) / USB 4 ports on your Mac.Belkins USB 3.0 4-Port Hub and USB-C cable let you continue to use your existing USB 3.0 peripherals with your new Mac. Or even whether an additional add-on card was necessary to use Thunderbolt 3 at all.USB C to USB Adapter USB C Ethernet Thunderbolt 3 to USB C HUB with 3 USB 3.0 Ports RJ45 Gigabit Network Adapter Compatible MacBook Air 2018 MacBook Pro 2017 2016 DELL XPS Chromebook HP Spectre (Silver)Overview. A PC user needed to look at the small print to know if their system could do 40Gb/s bandwidth, support multiple displays, power delivery, etc….
Thunderbolt Usb 3.0 Hub Mac With ABecause M1 or Intel, all Macs give you the same capabilities and can use all of the same great peripherals. So-called “Thunderbolt 4” is really a marketing term for those looking at PCs. The Mac Mini thunderbolt dock comes with a 2.5 HDD enclosure.The only other difference is that like the new Apple silicon Mac M1 models with Thunderbolt / USB 4, PCs designated with Thunderbolt 4 also have USB 4.So what we have now is current Intel Macs with “Thunderbolt 3 (USB-C)” and new Apple silicon Macs with “Thunderbolt / USB 4.” As for using Thunderbolt on your Mac, that doesn’t matter. There is also the USB A as well as a micro SD card reader to enhance connectivity. Oh, and no more add-on cards ever needed either.The HumanCentric USB C hub comes with 2 USB A 3.0 ports that offer excellent data transfer speeds. Thunderbolt 4 on a PC means (just like it always has been on a Mac) that all the so-called Thunderbolt capabilities and features are included. Now, with Thunderbolt 4, there is no option for a PC maker. ![]() The presence of VT-d specifically appears tied to the processor and motherboard chipset architecture and independent of Thunderbolt… And on the note of Thunderbolt security, Apple has addressed such in their OS/HW architecture many years ago.Up to 8K display support and the ability to support up to two 4K displays via Thunderbolt is not something Thunderbolt 4 adds. While i will admit my own need to dig deeper into VT-d, with respect to the safety and security of using a Mac as a Mac with MacOS – there is no compromise here. VT-d on a PC is required on Thunderbolt 4 systems. I want to hit a button or something to switch the inputs easily without yanking cables.I have also written to Apple about this too.Thunderbolt 4 as a name blurs the line between what Thunderbolt is and what is a requirement for the computer that Thunderbolt is on.The underlying Thunderbolt is the same 4 lanes of PCIe 3.0, 40Gbs max bandwidth, with a portion set aside for encapsulated Displayport.DMA Protection is not new on Thunderbolt with Thunderbolt 4 and VT-d, it’s presence/enabled status is a requirement for PC to be considered TB4. ![]() Historically, the vast majority of Thunderbolt users have been those with Apple Macs. Right now the only Thunderbolt 4 PCs are built off of Intel’s Tigerlake platform which is where the 8K video support comes from.For PC users – this does really make understanding and accepting Thunderbolt much easier. Intel has now used Thunderbolt 4 to both ‘confirm’ to a user it is a full Thunderbolt 3 (for lack of a better way to say) capability set on the PC + that the PC has certain capabilities at a minimum as well. Separate from Thunderbolt, but needed to use certain capabilities inherent of Thunderbolt.Apple defines what the Mac can do and we have the full feature set of Thunderbolt to utilize what a Mac is capable of. On PC/Windows systems, Thunderbolt with 8K capability isn’t new – but the Thunderbolt 4 spec requires that the PC hardware is able to support the connection of an 8K display now.Honestly – Thunderbolt 4 both cleans some stuff up for user exception while also muddying the water of actually what part of the requirements are Thunderbolt vs. In fact, Displayport 1.4 is how the Apple 6K display is able to operate at 6K. Apple defines the hardware and what the computer hardware supports. For using Thunderbolt devices on the Mac though, little to worry about. Those are system limitations independent of Thunderbolt.It would have been nice to not have the naming of Thunderbolt 4 out there at all. The M1 Macs have the fully Thunderbolt implementation even if they can not support eGPU or have more than one display connected via Thunderbolt. On a PC with Thunderbolt 3 – you had implementations where the Thunderbolt implementation itself was why you could connect/use/get fully bandwidth from a Thunderbolt 3 port – even if the PC itself had the capability to do so.It’s more confusing than really muddy as I’d also suggest, IMHO, Apple and Intel have split a bit now.Apple is listing the M1 Macs as equipped with Thunderbolt / USB4. Best gmail clients for macThe capabilities of Thunderbolt itself are not different on a Thunderbolt 4 PC vs. And all this stuff also works on a Thunderbolt 4 PC… which also technically has Thunderbolt 3 ports however you want to name it.Thunderbolt 4 has created unnecessary confusion because Intel has used it to clean up what Thunderbolt is on the PC. The same is true of M1 Macs with, again, the only exclusion I am aware of being eGPUs which the M1 architecture doesn’t presently support.But all your Thunderbolt storage, docks, PCIe expansion chassis, portable SSDs, everything that works on an Intel Mac with Thunderbolt 3 ports also works fine on the M1 Mac, which also has what Thunderbolt 3 ports. ![]()
