The keyboard is very light, it has a good battery life (I would even turn off, it remains in standby) and the use for Mac with MacOS parameterized "PC keyboard" is not a problem.
There are, however, two caveats: first, a second "Windows" key (or Command = Apple MacOS) is really necessary: the keyboard is held with one hand, if you have a "Command-I" to do, difficult to do the remaining hand as the two keys to be pressed too distant. If there were a Windows / Command key to the left of the space bar, the problem would be solved.
Then the "tap to click" on the touch part is really heavy: type often inadvertently. You can cancel this operation by pressing Fn-left button ... except you do it again between each standby ..
