Any Thunderbolt or USB dock can connect to a Thunderbolt 3 computer. USB devices can be connected to a Thunderbolt 3 or later port. DisplayPort and Mini DisplayPort devices are supported. Some functionality may be available if a Thunderbolt device is connected to a USB-C port; this is implementation-dependent, and not guaranteed.
Instead, the Mac's firmware enables its drives to behave as a SCSI, FireWire, Thunderbolt, or USB-C external mass storage device. A Mac booted in Target Mode can be attached to the port of any other computer, Mac or PC, where it will appear as an external device.
An attacker could, for example, use a social engineering attack and send a "lucky winner" a rogue Thunderbolt device. Upon connecting to a computer, the device, through its direct and unimpeded access to the physical address space, would be able to bypass almost all security measures of the OS and have the ability to read encryption keys, install malware, or control other system devices.
An Alternate Mode dedicates some of the physical wires in a USB-C cable for direct device-to-host transmission using non-USB data protocols, such as DisplayPort or Thunderbolt. The four high-speed lanes, two side-band pins, and (for dock, detachable device and permanent-cable applications only) five additional pins can be used for Alternate ...
The USB Device Class Definition for MIDI Devices transmits Music Instrument Digital Interface music data over USB. [119] The MIDI capability is extended to allow up to sixteen simultaneous virtual MIDI cables, each of which can carry the usual MIDI sixteen channels and clocks. USB is competitive for low-cost and physically adjacent devices.
Thunderspy is a type of security vulnerability, based on the Intel Thunderbolt 3 port, first reported publicly on 10 May 2020, that can result in an evil maid (i.e., attacker of an unattended device) attack gaining full access to a computer's information in about five minutes, and may affect millions of Apple, Linux and Windows computers, as well as any computers manufactured before 2019, and ...
USB4 also added support for USB3 tunnels and use of the USB2 wires for improved backwards compatibility with previous USB standards and to allow for simpler USB4 devices without support for PCIe. USB4 also added support for hub topologies compared to Thunderbolts previous restriction to daisy-chaining topology.
On the rear of the display is a Thunderbolt port, a FireWire 800 port, three USB 2.0 ports, and a Gigabit Ethernet port. The Thunderbolt port allows for the possibility of daisy chaining Thunderbolt Displays from a supported Mac, or connecting other devices that have Thunderbolt ports, such as external hard drives and video capture devices. In ...
