Earlier this week, we received a call from a client stating that they could not longer connect to their Windows device at their office using their personal MacBook. The client was receiving an error message “Unable to Connect” with the error code 0x3000064. This error is related to the latest version of the Windows Remote Desktop application in macOS.

Issue is caused by a faulty update on the Microsoft Remote Desktop app. To solve the issue, client must install a prior version of the Microsoft Remote Desktop app or install the Microsoft Remote Desktop Beta version 10.5.0 (1841).

Please note that some users using the latest macOS Big Sur (11.0.1) have noted that the Beta version of the app does not solve their issue. These users have downgraded to version 10.4.1 (1825) using the link below.

Download:

Prior versions of the Microsoft Remote Desktop app and the Beta version 10.5.0 (1841) can be found under Microsoft’s App Center. For prior versions, we suggest to uninstall the current app first before attempting the install of the older app.

The MicrosoftRemote Desktop Connection version 10 program in Macintosh OS offers many advanced features that can enhance your experience with remotedesktop.sou.edu or virtuallab.sou.edu

All of these settings are available when setting up the initial connection to remotedesktop or virtuallab, or you can modify them later by clicking on the Edit icon on the saved connection icon after starting Remote Desktop Connection.

Display Settings

Click on the Display tab to access display settings. An important setting is the ‘Use All Monitor’ setting, if you are using multiple displays the default setting is to use all monitors available. I have found it to be better to use just one, but that is a matter of preference. Here is where you make the adjustment.

If you are using a modern Apple computer with a high-resolution Retina display, you may want to enable the option to Optimize for Retina displays to ensure the best viewing experience.

Os X Windows Remote Desktop Client

Click on the Devices & Audio tab and then use the checkboxes to tell the Remote Desktop client whether you want to share your local printers, smart cards, clipboard, and microphone with the remote Windows computer. If you share your printers, you can print from the Windows environment and have it use your local printer. If you share your clipboard, you can copy and paste text (but not files--see the next section for how to share files) between your Mac and the Windows computer. If you share your microphone, you can make it available to the Windows computer if you need it.


Folders

If you want to share an entire drive with the remote session, such as your Mac's hard drive or an attached USB flash drive, you can select the root of the drive when you are asked to browse for a folder.
