Step 2: Double-click the installer package to open it. You can install Rosetta2 by opening a terminal and inputting the command 'run /usr/sbin/softwareupdate -install-rosetta'. Without this, your installation will silently fail. If you are using a Mac with an M1 chip, you'll need to install Rosetta2 prior to installing the Pulse Secure client. Step 1: Download the Pulse Secure VPN client package for macOS / Mac OS X (UCSB Box credentials are required to access the file). Note: You will need an administrator password to complete the installation.
