Before You Begin

  • Horizon Client requires a macOS High Sierra (10.13), macOS Mojave (10.14), macOS Catalina (10.15), macOS Big Sur (11), macOS 12, or macOS 13 operating system running on a 64-bit Intel-based Mac.

  • Horizon Client for Mac is supported with the latest maintenance release of Horizon 7 version 7.13 and later releases.

  • To install Horizon Client for Mac, download the disk image file from the VMware Horizon Client download page. For system requirements and installation instructions, see the VMware Horizon Client for Mac Installation and Setup Guide document.

Known Issues

USB Redirection

  • Connecting password-protected storage devices may not work correctly

    If you use the PCoIP display protocol, connecting some password-protected storage devices (such as IronKey USB flash drives) might not work correctly. For example, after you redirect the device to the remote desktop, the password prompt does not appear. The remote desktop shows that a new drive was added and so displays a new drive letter but no corresponding label to identify the device.

    Workaround: Configure Horizon Client to automatically connect the device when you insert it. From the Horizon Client menu bar, select Desktop > USB > Autoconnect USB Devices on Insert.

  • Transcend card reader device does not work with Mac host

    When you insert an SD card into a Transcend USB 3.0 card reader attached to your Mac client system, the SD card is not mounted automatically. Because the SD card is not mounted on your Mac client system, the device does not appear in the menu in Horizon Client and you cannot use the USB redirection feature to connect the device to the remote desktop.

    Workaround: Reinsert the SD card into the Transcend card reader. After the device is connected to the remote desktop, reinsert the SD card again to make the disk volume appear in the remote desktop.

  • Copied files do not appear on the drive after the drive is diconnected

    If you use the USB redirection feature to connect a Transcend USB 3.0 external hard drive to a remote desktop from your Mac client system, files that you copy or move to the drive do not appear on the drive after you disconnect the drive from the remote desktop.

    Workaround: Redirect the external hard drive to the remote desktop again. The files appear on the drive.

  • USB services are unavailable after certain operations

    When you connect to a Windows remote desktop, start USB services, redirect a USB storage device to the remote desktop, disconnect from the remote desktop, and then try to reconnect to the remote desktop, either USB services are not available in the remote desktop or you cannot reconnect to the remote desktop. In Horizon Administrator, the state of the machine is Agent unreachable.

    Workaround: If you are an end user, restart Horizon Client and try again. If you are a Horizon administrator, restart Horizon Agent in the machine.

  • Desktop connection is disconnected when the USB Automatically connect at startup setting is enabled

    After you connect to a remote desktop with the USB Automatically connect at startup setting enabled, the desktop connection is sometimes disconnected.

    Workaround: None.

  • USB devices not visible on the menu when you reconnect to a remote desktop

    If you connect and then reconnect to a remote desktop with the USB Automatically connect at startup setting enabled, all USB devices do not appear in the USB menu after you reconnect to the desktop.

    Workaround: Eject and then reinsert the USB device. For internal Mac devices, you might need to restart the computer.

  • System Extension Blocked error when you start USB service

    When you start the USB service on a macOS Mojave (10.14) or later system, the System Extension Blocked dialog box appears.

    Workaround: Click OK in the System Extension Block dialog box, navigate to System Preferences > Security & Privacy, and allow the extension to load.

Smart Card Authentication

  • Keychain Access app does not refresh when Smartcard is unplugged and re-plugged

    On macOS 10.13 or later, if you are using a TokenD driver, the Keychain Access app does not refresh when you unplug and re-plug in a smart card/smart card reader, and the Mac client cannot obtain the update status for the smart card. Because of this issue, the following problems might occur in Horizon Client on macOS 10.14 or later:

    • Smart card authentication does not work after you unplug and re-plug in a smart card/smart card reader.

    • Smart card redirection might not work after you unplug and re-plug in a smart card/smart card reader several times.

    • The Disconnect user sessions on smart card removal option in Horizon Administrator does not work.

    • The smart card removal policy on the agent machine might not work.

    Workaround: Switch to the CryptoTokenKit driver on macOS 10.14 or later. If you want to continue using the TokenD driver, for the smart card authentication issue, quit both Keychain Access and the Horizon Client app, relaunch Horizon Client, and perform smart card authentication again, making sure that Keychain Access is not launched. For the smart card redirection issue, reboot the Mac client machine, launch Horizon Client, and perform smart card authentication again, making sure that Keychain Access isn't launched. There is no workaround for the smart card removal policy issue with a TokenD driver.

  • Horizon Client might stop responding if security preference is set to Do not verify server identity certificates

    If you set the Horizon Client security preference (VMware Horizon Client > Preferences > Security) to Do not verify server identity certificates and connect to a server that has a valid root-signed certificate, Horizon Client might stop responding.

    Workaround: Unplug the smart card reader and then plug it back in.

  • Horizon Client is unable to verify the smart card's PIN when the smart card PIN is cached

    With the IDPrime .Net card, when the SafeNet Authentication Client middleware is installed, you can view or change the smart card's cache type. If the cache type for the IDPrime .Net card is Normal Cache, the client might not verify the smart card's PIN during server authentication when the smart card PIN is cached.

    Workaround: Change the Cache Type to "Always Prompt" for the IDPrime .Net card. This setting enables the client to verify the smart card's PIN each time the user connects to the server.

Printing

  • Location-based printer does not appear on printers list

    If multiple Horizon clients connect to the same RDS desktop or remote application simultaneously and map to a location-based printer with the same name, the printer does not appear in the printer list in all client sessions.

    Workaround: For the client sessions in which the printer does not appear, perform a manual refresh. For a remote desktop, press F5 or refresh the Devices and Printers window. For a remote application, close and reopen the application print dialog box. The location-based printer appears in the printer list.

  • Correct list of printers is not displayed for Windows Server 2012 RDS hosts

    Sometimes the virtual printing feature and location-based printing feature are not able to display the correct list of printers in the Devices and Printers window of a remote, session-based desktop. This issue can occur with desktops provided by Windows Server 2012 RDS hosts. The printers shown within applications are correct, however.

    Workaround: Log off the desktop running on the Windows Server 2012 RDS host and reconnect to it.

Displays and Keyboards

  • Remote desktop stops responding when you connect to it with the VMware Blast display protocol

    When you connect to a remote desktop with the VMware Blast display protocol from a Mac client system that has an NVIDIA GeForce GT 755M graphics card, the desktop stops responding.

    Workaround: None. This is a third-party issue.

  • Auto fit does not work for remote desktop if you change the display to full resolution

    If you launch a remote desktop with the PCoIP display protocol in full screen or window mode on an iMac with a Retina or monitor that supports a 5K display, and the screen size is more than 4K (4096 x 2160), auto fit does not work for the remote desktop if you change the display to full resolution.

    Workaround. None. This problem is caused by a PCoIP limitation.

  • Autofit fails when desktop enters full screen with two displays

    When you connect to a remote desktop that is running Windows 10 Creators Update with the VMware Blast display protocol, autofit fails when the desktop enters full screen with two displays.

    Workaround: Resize the window and autofit recovers.

  • Desktop stops responding when you connect to a remote desktop with the VMware Blast display protocol

    When you connect to a remote desktop with the VMware Blast display protocol from a Mac client system that has an NVIDIA GeForce GT 755M graphics card, the desktop stops responding.

    Workaround: None. This is a third-party issue.

  • Unable to see cursor movement on an extended monitor

    With the Session Collaboration feature, the primary session cannot see the cursor movement of the collaborative session if the primary session puts the cursor on an extended monitor.

    Workaround: Move the cursor back to the primary monitor.

  • Connection to remote desktop with VMware Blast display protocol in full-screen or window mode fails

    If you start a remote desktop with the VMware Blast display protocol in full-screen or window mode on an iMac that has a Retina display or a monitor that supports a 5K display with Full Resolution mode, and then disconnect and reconnect with the PCoIP display protocol, the connection fails and the remote desktop does not start.

    Workaround: This problem is caused by a PCoIP limitation. Change to Normal mode and use the PCoIP or VMware Blast display protocol.

Touch Bar

  • Open selection window and Launch Item List Touch Bar items do not work

    When you are using a remote desktop in full-screen mode on multiple displays, if you click Customize Touch Bar on the external display and click Done, the Open selection window and Launch Item List Touch Bar items do not work.

    Workaround: This problem is a third-party issue. Apple fixed this issue in macOS 10.14 Mojave.

  • Focus for front window is lost when you use the Touch Bar to switch between published applications

    You might lose focus for the front window when you use the Touch Bar to switch between published applications that are hosted on Windows Server 2016. This problem can also occur when you press Command+~, or click the dock icon, to switch windows. This problem typically only occurs after switching windows several times.

    Workaround: Use the mouse to click the window and regain focus.

Miscellaneous

  • Changes to webcam and audio devices not detected by Real-Time Audio-Video feature

    Changes to webcam and audio devices that are connected to, or disconnected from, the Mac client system during a remote desktop session are not detected by the Real-Time Audio-Video feature.

    Workaround: Disconnect and reconnect to your remote desktop session to detect webcam and audio device changes. For example, if you connect a USB headset to the Mac client system during a remote desktop session and you want to use that headset on the remote desktop, you must disconnect and reconnect to the remote desktop session to make the headset available.

  • Unexpected results when you edit an application pool in Horizon Console

    If an administrator edits an application pool in Horizon Console and changes the path to point to a different application that already has an application pool associated with it, unexpected results can occur. For example, the original application might be launched from the Mac Dock instead of the new application.

    Workaround: Make sure that each application in a farm is associated with only one application pool.

  • Cannot launch an application from Mac Dock

    Users cannot launch an application from the Mac Dock if multiple application pools point to the same application in one farm, and if the application pool the users selected was created with associated parameters in Horizon Console. If a user saves the application in the Mac Dock and tries to open the saved item, the application fails to launch with the associated parameters.

    Workaround: Make sure that each application in a farm is associated with only one application pool.

  • Poor performance when copying and pasting between a remote desktop to a shared folder

    If you use Horizon Client on a new MacBook, and you use the USB-C port to connect to the network, you might notice poor performance when copying and pasting between a remote desktop to a shared folder.

    Workaround: None.

  • Cannot log in to a server as a different user if the Remember this password check box is selected

    If you select the Remember this password check box when you log in to a server, you cannot log in to the same server as a different user if the credential caching timeout period (clientCredentialCacheTimeout) on the server has not yet expired. Horizon Client will automatically use the saved credentials to log you in to the server.

    Workaround: Remove the server from the Selector window (right-click the server icon and select the Delete menu item), click the Add Server button to add the server again, and then log in to the server as the different user.

  • Response time of Windows Server 2016 hosted remote applications is slow

    On late 2016 MacBook Pro client systems, the response time of Windows Server 2016 hosted remote applications is slow in the first few seconds after you launch a Windows Server 2016 application or switch the top window between Horizon Client and the Windows Server 2016 application window.

    Workaround: None. This is a third-party issue.

  • Remote application sessions are disconnected after pre-launch timeout expires

    If you connect to a remote application for which the pre-launch feature is enabled on a Horizon 7 version 7.2 server, and the Horizon Client reconnect behavior is set to "Ask to reconnect to open applications" or "Do not ask to reconnect and do not automatically reconnect," resumed application sessions are disconnected after the pre-launch timeout expires (default 10 minutes).

    Workaround: Set the Horizon Client reconnect behavior to "Reconnect automatically to open applications."

  • Maximize icon does not appear when you hover your mouse over the Close icon

    With Moom 3.2.12 (3240), the Moom UI appears when you hover your mouse over the Close icon in Office 2016 and 2019 apps instead of the maximize icon.

    Workaround: None.

  • Focus lost for front window when using custom controls in Moom app

    You might lose focus for the front window when you use custom controls in the Moom app to move or resize published applications that are hosted on Windows Server 2016 or Windows Server 2019.

    Workaround: To regain focus, use your mouse to click on the title bar of the application window.

  • Horizon Client for Mac stops responding

    Horizon Client for Mac stops responding if you unplug an external graphics processing unit (GPU).

    Workaround: None.

  • Cannot start a VMware App Volumes application

    You cannot start a VMware App Volumes application from the Dock on the client system.

    Workaround: Start the application from Horizon Client, or use a shortcut.

  • Moom user interface does not work

    The Moom user interface does not work for UWP published applications.

    Workaround: None.

  • URL Content Redirection can not work for non-browser applications

    On client systems running macOS 11.5.1 and preview releases of macOS 12, client-to-agent URL Content Redirection does not work for non-browser applications.

    Workaround: Open the URL using the VMware Horizon URL Filter, as described in VMware Knowledge Base (KB) article 85733.
