What happens when you copy something on your Macbook?
When you copy something on Mac OS, it gets stored temporarily by the clipboard. This acts as an intermediate storage location for your data, and when you paste it to another location, the same moves from the clipboard to another application.
Although the copying process might seem trivial to the end-user, a lot happens in the background, and everything is managed by a process (daemon) called Pboard on your Macbook.
A high-level overview of the copy-paste process on Mac OS is as follows:

- Process initialisation: The Pboard daemon generates the pasteboard process, which is responsible for storing the copied data.
- Data conversion: The copied data gets converted into one of the several standard formats.
- Data transfer: The Pboard daemon then sets up the XMP messaging protocol and sends data to specific pasteboard based on the data type of the copied data.
- Data storage: The pasteboard holds and stores the data until another application requests it.
- Data transfer: The Pboard daemon uses the XMP protocol to transfer the pasteboard to the desired application.
- Data conversion: The application processes the received data and displays it in the desired format.
Now that we understand the basics of the copy-paste mechanism on Macbook, we can try to solve the issue at hand.
