- Pseudo-HiDPI support, for a smooth and sharp user interface regardless of screen size. Pseudo-HiDPI mode is disabled by default, enable it in Preferences > General > Appearance. Scaling in RawTherapee depends on font size, DPI and display scaling. While scaling has been tested to work well in Windows, Linux and macOS, there are some macOS display modes which are incompatible with it, specifically those modes suffixed by “(HiDPI)” in macOS Display settings. Some versions of macOS (10.14.*) seem to not list any modes, in which case the user must just give it a try.
