Setting up an IC card reader (macOS)

You can use an NTT Communications IC card reader in macOS.
Make sure to read the following notes before you do so.


  • USB power supply problems on Mac computers can prevent card readers from recognizing cards correctly.
    If the issues persist when you connect directly to the USB port on your machine, use a self-powered USB hub.
  • As the Tokyo Institute of Technology has yet to verify the operability of the Request System for Goods, etc.,on macOS, you may not be able to get help with issues that occur as a result of a version update or other similar procedures.

Operating verification environment

  • Mac OS X 10.11*1
  • macOS Sierra 10.12*1*2
  • macOS High Sierra 10.13*1*2
  • macOS Mojave 10.14*1
  • *1 Operating ACR39-NTTCom, ACR1251CL-NTTCom only

Installing drivers and the certificate management tool

As you will need to restart your computer after installation is complete, make sure that
you have closed all your open applications before starting the installation procedure.

  1. Click this link (accessible to on-campus users only) to download the dmg file.
  2. Mount the dmg file and hold down the Control key, click, and select "Open".
  3. Click "Open".

  4. Click "Continue".
  5. Choose an installation location and click "Install".
  6. Enter your administrator password and click "Continue Installation".
  7. Click "Restart".
  8. Connect your IC card reader and your IC card. Then open Keychain Access,
    which is in the Utilities folder under Applications.
  9. Select "All Items" from the pane on the left. If you see "eSK Card #number"
    in the list of keychains in the top left corner, the system has successfully
    recognized the card reader and your IC card.
    Launch your browser and complete the certificate authentication process for
    access to the Tokyo Institute of Technology Portal.
    Note: Please insert your IC card into the IC card reader beforehand.
    Make sure that after inserting your IC card, open "Keychain Access".

  10. When you do the authentication procedures in Safari, you will see
    a "Please enter the keychain password" message.
    Enter your PIN code here.

Web browser settings

macOS computers with multiple users will have difficulties reading IC cards in Safari.

When using Safari or Google Chrome

You do not need to configure any additional settings.
If you cannot get authenticated, please use Firefox.

When using Firefox

Go to "Open menu" in Firefox and open "Preferences" to add security devices.
