The default clipboard works fine until it doesn’t. Here are the most frequent frustrations Mac users experience daily.
As soon as you copy something new, everything previous is permanently lost. This is the #1 complaint.
You cannot search through previously copied content. If you need something from 10 minutes ago, you have to find the source again.
Important snippets get buried under new copies. There is no way to save frequently used items separately.
One accidental copy can destroy carefully selected content, especially when working across multiple documents and browsers.
