Ctrl+Shift+/Mac
Cmd+Option+/Wraps the selection in a block comment. The Mac keymap swaps Shift for Option here, so the usual "take the Windows one and add Cmd" guess fails outright, and in languages that have no block comment nothing happens at all.

IntelliJ IDEA ships a different default keymap per platform, and two of them on macOS — "macOS" and "macOS System Shortcuts" — so when nothing works, look at Keymap in Settings first; whichever you pick then serves PyCharm, WebStorm, GoLand and Android Studio unchanged.
Reading the key names
- Keys joined by + are pressed together: Ctrl+Shift+P means hold Ctrl and Shift, then P.
- On a Mac, Cmd is ⌘, Option is ⌥ (labelled Alt on some keyboards), Control is ⌃ and Shift is ⇧.
- Windows Ctrl usually becomes Cmd on a Mac, but not always — this reference lists both combinations separately.
- With a Korean, Japanese or Chinese input method active, shortcuts built on letter keys may not fire. Switch to Latin input and try again.
- When a combination does nothing, another program has often claimed it as a global shortcut first.
