Setup and troubleshooting →Latest updates
- Open notices and customer support from the menu bar or Settings, with a quick link to web support.
- Get a notification when MFLab posts a new notice. Turn it on in Notices & Support; every notice is still listed there. Settings now link to the website, changelog and privacy information.
- Mac-Monitor is now installed as Mac-Monitor.app with MFLab's standard app identity. Download the latest DMG, drag Mac-Monitor.app to Applications and delete the old MacMonitor.app. Settings such as display names, keyboard shortcuts and Launch at login start fresh.
- Added software dimming for displays that do not support DDC brightness control (such as TVs and certain HDMI monitors). You can now dim their brightness from the menu bar via gamma table scaling, with a minimum brightness threshold to prevent the display from going fully black.
- Updated menu bar brightness and volume controls with custom sliders that keep active colors visible before the panel gains window focus, and allowed software dimming to fully black out the display at 0%.
