+### macOS DMG covers
+
+The DMG files uses `macos/background.tiff` as the background, which is created from
+`macos/background.png` and `macos/background@2x.png` with the following command:
+
+```sh
+tiffutil -cathidpicheck macos/background.png macos/background@2x.png -out macos/background.tiff
+```
+
+`macos/background@2x.png` should be double the size of `macos/background.png` with 144 PPI.
+You can set the PPI by running:
+
+```sh
+sips -s dpiWidth 144 -s dpiHeight 144 macos/background@2x.png
+```
+
+`sips` and `tiffutil` are available by default on macOS.
