When engaging the app, my screen just goes black until I quit the app unless I'm running a full screen show. Very annoying. Possibly not up to date with Big Sur software, but don't waste your money!

The app does what it says - the keyboard and trackpad are all locked when activated. I didn't try the exception for volume adjustments. This really needs a fre improvements to be stellar, though.1) Move BabyProof from the dock to the menu bar.2) Assign a global hotkey to activate the lock.3) Create a key combination to temporarily suspend the lock (useful for starting a video after locking the screen, otherwise your movie is playing while you're still trying to get the lock in place - a hotkey to start the lock would achieve the same thing, but a suspend lock option would also allow you to do things like skip back or pause a video without having to do through the whole unlock/lock process, which is still rather tedious).Mostly, even though the app works, I rate this 3 stars because of how cumbersome getting the lock started is, and that there's no way to interrupt the lock for a single command, having to unlock and re-lock instead. The current 2.5 stars is fallacious, though, if you both look at all the reviews (none lower than 3, so how is the average lower than that!?) and the fact that this does work, however inconveniently. So I bump it to 4 stars, but still would love to see some polish on it.

Thank you so much for making BabyProof! It's really helpful!I use it primarily for letting my daughter press keys while I'm reading however, so it would be really helpful to have the ability to enable scrolling, perhaps with two fingers on the trackpad, or simply with the arrow keys.

I've not had a single problem with this app since purchasing it several versions of OS X ago.
