Quick Reference
Tips for macOS (Mac App Store) Screenshots
For the Mac App Store, screenshots must be landscape-oriented with a minimum resolution of 1280×800 and a maximum of 2880×1800 pixels. Apple recommends submitting at the highest resolution possible, making 2880×1800 the ideal target for Retina display quality. Screenshots are displayed in a wide, horizontal canvas reflecting macOS's desktop environment, so showcasing your app's full window interface is essential. Avoid alpha channels — only PNG or JPEG formats without transparency are accepted. Since Mac users expect polished desktop UI, your screenshots should highlight keyboard shortcuts, menu bars, and multi-window workflows that resonate with power users.
Common Mistakes to Avoid
Three common mistakes when preparing Mac App Store screenshots: First, submitting portrait-oriented images — macOS requires landscape only, and anything outside the 1280×800 to 2880×1800 range will be rejected. Second, including alpha transparency in PNG files, which causes immediate upload failures. Third, submitting at low resolutions like 1280×800 when high-DPI Retina displays render small text and UI elements poorly — always target 2880×1800 pixels to ensure crisp, professional-looking visuals that compete effectively on the Mac App Store product page.
Conversion Tip
High-quality 2880×1800 screenshots that showcase your Mac app's full desktop interface immediately build trust with power users. Wide landscape canvases let you highlight complex workflows and rich UI, helping browsers grasp your app's value instantly and driving significantly higher download conversions on the Mac App Store.
