How to refresh the browser on macOS?
Regular shortcut is Cmd - Shift -R.
Workaround for F5 adapted from https://productforums.google.com/forum/#!msg/chrome/If0TdQ2m6hU/ZSrbu8BCDpwJ:
- Go to "System Preferences" -> "Keyboard" -> "Shortcuts" -> "App Shortcuts"
- Hit the little "+" button under the main white area
- In the little pup-up window select "Google Chrome" as the Application
- Type in "Reload This Page" in the "Menu Title" field exactly as it appears in the Chrome's View menu (no quotes of course)
- Click inside the "Keyboard Shortcut" field and hit F5 key (or any desired combination)
- Finish with "Add". Shortcut should work directly.
Macs show you their keyboard shortcuts right in the menus. If you look on Safari's View menu and see the Reload Page command, you'll see it's shortcut is Cmd-R.
Historically, Mac keyboard shortcuts rarely use function keys (F1-F15), because Mac designers and users have tended to favor more compact keyboard layouts that don't have room for the F key row, or nowadays, because that row is primarily used for brightness and volume keys.
Refresh: CMD+R (same as F5 on Windows/Linux)
Refresh cleaning cache: SHIFT+CMD+R (same as CTRL+F5 on Windows/Linux)
