And I'm a pretty impatient person when it comes to keyboard and mouse response. Go to Karaviner-Elements.app, select the keyboard, switch the left command and option keys map rightgui to mouse5 (Mouse buttons- button5) Remap F7F9 to match the keyboard symbols. Honestly, I never really noticed it, perhaps because I've been trained to expect a little pause while a napping computer wakes up. When I wake my Mac up, it takes - and I'm estimating here - a quarter second between when I tap the keyboard and when I can start typing my password to log back in. I've been using a Bluetooth keyboard and mouse with a MacBook for more than three years now, and I have no trouble. That all sounds very reasonable, but here's the deal.

It's noticeable if you are in a hurry to jump online, and the USB connectivity alleviates that small delay. The 'lag' we talk about is very small - about a second or less. Even a PS/2 keyboard can be used with a Mac as long as you have a PS/2-to-USB adapter, which can be bought inexpensively online and at electronics stores. When the user begins typing or mousing again, they will experience a brief lag before the Bluetooth reconnects. However, it will go into sleep mode to conserve battery life if it's not used for several minutes. The 2.4 GHz USB connection instantly reconnects as soon as you touch the mouse.īluetooth is particularly great for mobile scenarios since it offers wireless, dongle-free connection.

Sculpt Ergonomic Keyboard uses a 2.4 GHz USB connection, which is better suited for desktop computing where a person may periodically step away from their computer. When I asked why it went with a proprietary wireless technology, Microsoft told me it found that Bluetooth imposed an unacceptable lags when Bluetooth devices wake back up after idle periods:
