Im trying to help my mum set up her imac and she has asked me to help make the text bigger on the screen. Ive shown her how to zoom on word/safari/etc, however ideally I want to make all the text on the computer bigger - eg. menus at top of screen, finder text, etc... The first thing I tried was adjusting the display resolution from 1920x1080 to 1600x900 or 1280x720, but this seemed to make the screen blurry. Does anyone know if there is any other way that I can help make the text bigger for all system elements?
