Stop Squinting: How to Fix macOS’s Tiny Upload Window Icons

If you use a Mac, you’ve probably hit this infuriating UI quirk: when you click "Upload," the macOS file picker displays microscopic thumbnails. Unlike a normal Finder window, there’s no slider to scale them up. Fortunately, there’s a permanent, 30-second fix. We just have to bypass the UI and tell macOS exactly what we want using Terminal.

The 30-Second Fix

1. Open the Terminal app (Cmd + Space, type "Terminal", and hit Enter).
2. Copy and paste this exact command: defaults write com.apple.finder FK_DefaultIconViewSettings -dict-add iconSize 256
3. Hit **Enter** and close Terminal. That's it! The next time you upload a file in Safari, you'll get massive, glorious thumbnails where you can actually check your focus. *Note: If `256` is too large for your screen, simply run the command again with a smaller number like `128`.*
