Installation and support for Mac OS

Install and use your 3SKey token on a MAC


Support for MAC OS:

The use of 3SKey tokens has been qualified on MAC OS. The support is limited to using 3SKey tokens on a MAC for signing transactions. The token management - including the activation - on the 3SKey portal has only been qualified on PC.


When your token has been activated and the software has been installed on your MAC please liaise with the support of your signing application for instructions and support on using their application on a MAC.

Note : The driver for MAC is supported only on the following operating systems:

  • MAC OS X 10.15 (Catalina)
  • MAC OS X 10.14.6 (Mojave)


Depending on your MAC configuration a message may appear during installation stating that the installation file cannot open because the developer cannot be verified, please refer to the instructions available at to open the file.

When you start your MAC with a new 3SKey token inserted you may be prompted to pair the smart card with your user account. Click Cancel so that the 3SKey token is not paired to your MAC user account.


How to verify that the certificate is detected on your MAC:

When the Safenet software has been installed on the MAC you can plug your token and verify that the certificate is detected properly:

  1. Click the Safenet Authentication client icon to open the menu. The icon is located in the top-right corner of your monitor when a token is inserted.
  2. Select Tools menu
  3. Click the icon to access the Advanced Settings
  4. Under SWIFT_PDI open User Certificates. The 3Skey certificate appears. If it is activated, it is valid for 3 years.
  5. You can also test the token password by clicking the Safenet Authentication client icon then Certificate Information, and click the Logon button at the bottom left of the new window.

With MAC 10.14 the certificate will be available in the MAC Keychain Access (Finder > Applications > Utilities > Keychain Access) under SWIFT_PDI. After selecting SWIFT_PDI you can test the token password by clicking on the Lock symbol on at the top of the page.

With MAC 10.15 the certificate is no longer visible in the Keychain Access. You can confirm the detection of the token and certificate in the MAC operating system using the following commands in a Terminal:

security list-smartcards
sc_auth identities

Please contact the support of your signing application or portal for further instructions on how to use the token and details on the prerequisites (browser, sconnect, java...). When you insert the token the certificate is automatically available in Safari or Google Chrome. With Mozilla Firefox, you must install the security module as instructed below.

Note : If your signing portal still uses Java applets please consult the website to learn what the recommended web browsers versions are.
