I have a desktop Dell OptiPlex which causing the screen flickering issue please check this below image:I have did the following but still now luck: What can cause a screen to flicker? Hardware.In summary, for my problem, to get the Mac and PC clipboards to work in unison, I needed to understand that the adjustment was under 'Connections', that the 'Edit PC' option only shows up under certain conditions, and that the settings for the clipboard is under 'Devices & Audio'. (So, at that point, both 'Command' and 'Control' meta keys work on the remotely connected PC). Regarding meta-keys, other answers on this page explain that by default ' Command-C' etc are used on the Mac while ' Control-C' etc are used on Windows, and that this can be expanded so that the Mac's 'Command-C' type keyboard controls will also work on the PC. I am now able to transfer data from Mac to PC and from PC to Mac using the clipboard so 'copy, cut, paste' all work smoothly between the machines. Once I did that, I was able to reconnect, and this time the Mac clipboard and the PC clipboard became unified as a single, shared clipboard. In the 'Edit PC' pop-up, after assuring that 'Clipboard' is checked, click on 'Save'.Within the ' Devices & Audio' tab, there is a set of checkboxes 'Printers', 'Smart cards', 'Clipboard'.In the 'Edit PC' pop-up, there is a set of tabs ' General | Display | Devices & Audio | Folders'.From the 'Connections' menu, select 'Edit PC.' (If you don't see the 'Edit PC' choice, then you did not correctly select the PC icon, as per prior step above.). The drop down for the 'Connections' menu should present a choice labeled 'Edit PC'.In the application menu bar, which is always at the top of the screen on a Mac, select the 'Connections' menu.

In my case, I have only a single connection configured, so there is just one icon, so I just made sure that this icon is selected. In that window, select the particular icon for the PC of concern.In the 'Remote Desktop' app, in the 'Remote Desktop' window, where there is a choice at the top of the window between 'PC' versus 'Workspaces', I have 'PCs' selected.Have 'Remote Desktop' running on the Mac, but do NOT have the session connected to the PC.To get cut-and-paste to allow transferring clipboard data between the Mac and the PC, I did the following: The PC I am connecting to is a Windows Server 2008 R2 DataCenter copyright 2009. The year is 2021, and I have Microsoft Remote Desktop Version 10.6.3 running on a Mac OS X Catalina OS X 10.15.7. OK, I got transfer via clipboard to work.
