macOS Client v5.6

The gradual rollout of macOS Client version 5.6 started on the week of Apr. 15th, 2024. This version contains:

  • Device Posture Check for Disk Encryption: You can now include a check for Disk Encryption within your Device Posture Profiles. The Device Posture Profile can be included in your Client Connectivity and Security policies
    • This feature will be gradually enabled over the next few weeks
  • Updated Client Tray Icon: We improved how the Client’s tray icon indicates a connected or disconnected status
  • New Indication of System Notification Status: On the Settings page, we added the status of System Notifications and improved the messaging to highlight their importance
  • Bug fixes and stability improvements

macOS Client v5.5

The gradual rollout of macOS Client version 5.5 started on the week of Jan. 8th, 2024. This version contains:

  • Always-On Enhancements: We are introducing new features that ensure Always-On can be used while maintaining business continuity:
    • New Bypass Mode for Always-On: Users can temporarily access the Internet without waiting for admin approval. Users provide a reason in the Client and Always-On can be temporarily bypassed and the Client can disconnect
    • Always-On Recovery Mode: Users can access the Internet if a connection to the Cato Cloud is unavailable. For example, if a Captive Portal prevents the Client connecting to Cato Cloud, users can still access the Internet, bypassing Cato security
  • Improvements to Device Posture Checks: The new version supports a new device posture check and enhances the Anti-Malware check:
    • New DLP Device Posture Check: You can now include a check for DLP within your Device Posture Profiles. The Device Posture Profile can be included in your Client Connectivity and security policies
    • Real Time Protection for Anti-Malware Device Check: Connected devices are continuously verified to ensure they meet the requirements of the Anti-Malware Device Check
  • Support for macOS Sonoma: The Client now supports macOS Sonoma (macOS 14)
  • Stability Improvements: The new Client version provides users with increased network stability. Key improvements include:
    • Resiliency during network changes
    • Authentication after device wakes up
    • Optimizing time-to-connect

  • For known limitations for this version, see details below.

macOS Client v5.4.3

The gradual rollout of macOS Client version 5.4.3 started on the week of Oct. 8th, 2023. This version contains:

  • Stability fixes and security enhancements including:
    • Resolved issue that caused the device certificate check to fail after upgrading from version 5.3 to 5.4

    • Resolved issue that caused the Client to be unresponsive after collecting logs if the device clock was not configured to 24 hours format

    • Hardened the Client upgrade mechanism to protect the upgrade components

macOS Client v5.4

The gradual rollout of macOS Client v5.4 started the week of July 23rd, 2023. These are the features and enhancements for this version:

  • New Device Posture Check for Device Certificates Provides Increased Security: You can now include a check for a device certificate within your Device Posture Profiles. The Device Posture Profile can be included in your Client Connectivity and security policies. This check:

    • Improves Device Authentication by ensuring the SDP users or user groups in the rulebased policy have the required certificate before connecting to your network

    • Lets you define stricter Device Posture requirements in your Firewall policies to access corporate resources

  • Always-On Now Supports Temporarily Bypassing the Cato Network: SDP users with Always-On can temporarily bypass Cato security and access the Internet by entering a bypass code in the macOS Client (the same experience as bypass code for the Windows Client)

  • Enhanced Client PoP Selection: We improved the PoP selection process to better consider multiple factors including geography and availability. The Client now more accurately selects the best PoP to connect to.

  • End of Life for macOS Catalina: Following Apple's announcement that Catalina (version 10.15) is declared end of life, the macOS Client no longer supports this version

  • Bug fixes:

    • Improved reconnect after a device wakes up from sleep mode with Always On

    • Re-authentication with external browser opens single browser tab

    • Improved Client connectivity when downloading or transferring large files

macOS Client v5.2

The rollout for the gradual upgrade for macOS Client version 5.2 started on November 13th, 2022, and includes:

  • Enhanced Reauthentication Experience: A notification lets users know that the SSO or MFA session will soon expire, and allows them to seamlessly reauthenticate. Read more.

  • Status Bar Icon: Users can easily connect, disconnect, quit, and open the Client right from the status bar of macOS devices.

Known Limitations for macOS Client v5.4

This section lists known limitations that apply to all the macOS Clients version 5.4 and higher.

  • If you downgrade the Client to v5.3, it may become unresponsive. To resolve this issue, restart the Client from the Application folder or Launchpad

  • If you downgrade the Client to v5.3, users other than the last connected user are removed
  • With Always-On enabled, after a device wakes up or connects to a network, if Zoom is installed on the device, the Zoom app may open a pop up with a connection error. To resolve this issue, restart Zoom

  • If you manually install the VPN Profile and have Device Certificate checks included in the Device Posture Profile, a pop up is displayed requesting the keychain password

  • If you upgrade the Client with an MDM, pop ups are sometimes displayed requesting permission to allow the installation of system extensions and the VPN configuration

  • If you upgrade the Client manually, pop ups are sometimes displayed requesting permission to install the Client
    To prevent this issue, you can first distribute the permissions for DMG extension and the VPN payload, then distribute the Clients to the macOS hosts

  • Connecting to Cato is only supported from within the Client.  Connecting from System Preferences > Network (or from macOS Ventura System Settings > VPN) on the device is not supported 

  • If an Anti-Malware Device Check with real time protection enabled is configured to check for the following vendors and products, the Device Check fails and the Client is unable to connect to the Network. To continue to check for these Anti-Malware vendors and products, disable real time protection.
      • AVG AntiVirus
      • Apex One (Mac) Security Agent
      • Avast Business Antivirus
      • Avast Mac Security
      • Comodo Antivirus for Mac

Known Limitations for macOS Client v5.0 and Higher

This section lists known limitations that apply to all the macOS Clients version 5.0 and higher.

  • This Client version uses the 85.255.31.1 IP address as part of the infrastructure to support Single Sign-On (SSO)

    • Make sure that this IP address is NOT blocked by any third-party anti-malware software

  • For accounts that use Azure Conditional Access, please set the Browser Authentication to External Browser (Access > Client Access > Authentication) For more information about Browser Authentication, see Configuring the Authentication Policy for Cato Clients

  • For macOS devices with the Symantec Web Security Service (WSS) agent installed, we do not currently support installing the WSS agent and the macOS Client on the same device

  • Uploading a local split-tunnel file to the Client is not supported. You can use the global split-tunnel settings in the Cato Management Application

  • For OneLogin SSO, we recommend that you use the internal in-Client browser. When Browser Authentication is set to External Browser, if the browser window or tab is closed, the end-user can't authenticate to OneLogin
