I realise this is a very old thread, but I'm considering getting a new MBP 13 and have a trusty Lenovo USB3 dock which I'd prefer not to have to replace (it's not necessarily a deal breaker but could be another $150-$250 I'd prefer not to spend in switching back to Mac). I currently use the dock for Gb Ethernet, 2 DVI screens, multiple USB peripherals (mostly USB 2). Lenovo only supports/supplies Windows drivers for this dock, but has 'DisplayLink USB Graphics Software for Mac OS X' 3.0.0 including Sierra 10.12.3 support (readme ). Can anyone share their experiences with the Lenovo USB3 dock on a recent Mac? (bonus points for USB-C 😀) TIA!

The Embedded Security Subsystem The Embedded Security Subsystem is a chip on the ThinkPad's mainboard that can take care of certain security related tasks conforming to the TCPA standard. It was first introduced among the T23 models and is now under the name 'Embedded Security Subsystem 2.0'.

It is an integral part of most of the modern ThinkPads. The functions of the chip fall into three main groups:. Public key functions. Trusted boot functions. Initialization and management functions The purpose of the Embedded Security Subsystem is to keep the user's sensitive data out of range from software based attacks (like viruses, Internet attacks etc.).
One way the chip offers to achieve this is by providing storage for keys along with the necessary functions to handle them within itself, so that a for example a private key never has to leave the chip (can't be seen by any piece of software). Besides this, there are more complex topics covered by the functionality of the chip.
If you want to find out more about it you can find good documents on the. Current ThinkPads have the TPM chip integrated into the SuperIO chip, or integrated into the chipset. Don't let the picture fool you. Trusted or Treacherous? In addition to benefits (such as in-hardware storage of cryptographic keys) TCG standards have some drawbacks. As ThinkPads of recent generations following the ThinkPad are equipped with this disputed TCG-/TCPA-Technology, it can be interesting, which promises of the TCG are fulfilled inside your ThinkPad and which parts of the TCG-specifications still seem to be a privacy issue for every user of digital devices like a MP3-player or a ThinkPad - so please read for more details.
Linux Support There are three main drivers that support most of the ThinkPads. tpmatmel - for those ThinkPads with older Atmel 97SC3201 chips. tpmnsc - for the ThinkPad T43/P and R52. tpmtis - for recent ThinkPads with TPM 1.2 In addition you will need some something like, which your distribution may have packaged as tpm-tools.

The earlier of them didn't yet have the Embedded Security Subsystem, but a kind of pre 1.0 version called the Embedded Security Chip. This chip had the following capabilities:.
Data communications authentication and encryption. Storage of encrypted passwords Embedded Security Subsystem (1.0) The original Embedded Security Subsystem (in IBM documents there is no use of the additive version-number 1.0) claims to be compliant with TCG specs, but apparently did not fully implement any specific TCG spec. The Embedded Security Subsystem has the following features:. hardware key storage. multi-factor authentication. local file encryption.
enhances VPN security Embedded Security Subsystem 2.0 The Embedded Security Subsystem 2.0 conforms to the TCG TPM 1.1b specification, with a TPM manufactured by either Atmel or National Semiconductor, and TCG TPM PC client 1.1 BIOS extensions. The Embedded Security Subsystem 2.0 has the following features:. hardware key storage. multi-factor authentication.
local file encryption. enhances VPN security. TCG compliant ThinkPads with Atmel chips are supported by the tpmatmel kernel module. The few ThinkPads with National Semiconductor chips (T43/p and R52) are supported by the tpmnsc kernel module. Trusted Computing Group TPM 1.2 Since the.60 series Thinkpads all new models have had TCG TPM 1.2 compliant chips. During the.60 series this was part of an ATMEL chip, in later ThinkPads this is actually part of the Intel chipset itself. Regardless if it is part of the Atmel chip or the Intel chipset, these TPM 1.2 devices are supported by the tpmtis kernel module Clearing/Reseting the Embedded Security Subsystem.
A password-locked HDD can be made useful again by using a low-level utility capable of issuing the SECURE-ERASE command to it. You will lose all data, but at least the HDD will be usable again, as that also unlocks the HDD. If there is a need to reset and clear the TPM chip, the IBM BIOS has a 'Clear Security Chip' option that will work (as long as you did not issue one of the very few 'permanently lock the TPM chip in a certain state for life' commands, so Do Not Do That!). That option is not readily accessible. To unhide it and reset the TPM chip, you have to: Method 1.
Power down the ThinkPad;. Power up the ThinkPad, with the Fn key pressed (or CTRL in a ThinkCenter);. When the BIOS screen shows up, release the Fn key;. Press the required key to enter the BIOS configuration;. Enter BIOS supervisor password if required;. Go to the security menu, security chip submenu, and clear the TPM chip.
