I deleted all the photos on Mac system, but the system still shows that there is still so much memory occupied. What should I do?

Reason: Deleting photos only moves the photo files from the Photo Library to the Trash. The Trash itself still takes up computer disk space.

Solution: Just clear the Trash. The operation is as follows:

1. You can see the "Trash" icon on the far right side of the Mac system taskbar;

2. Right-click the Trash and select "Empty Trash" "Trash";

3. The system will prompt "Are you sure you want to permanently erase the items in the Trash?" Click "Empty Trash" to completely delete the disk occupied by the photo files. space.
