How to pick the right combo
For classic Mac home-office we recommend Bluetooth combos with no USB dongle — that saves the scarce USB-C port on a MacBook. If you switch between several older PCs without Bluetooth, a 2.4 GHz Unifying combo (one dongle for keyboard + mouse) is better. Logitech MK270 is the affordable plug-and-play pick, MK540 Advanced adds multimedia keys and a palm rest, the MX Keys + MX Master combo is the premium tier for power users.
