Mac Wallet does not seem to be staking -- i transferred from a Windows Wallet 50+ hours ago and it says I do not have mature coins--- does the Mac wallet work correctly
There are no code differences between the windows and mac wallet. How old is your oldest coin? You can see this in coin control. If you just started your wallet after 50 hours, you will get some reason as to why you are not staking. Usually, you just have to wait a few minutes for the staking thunderbolt to turn solid.
how to see turbostake ? I have a section staked the time is frozen at the expected time of receiving the award 42 seconds
That number is just an estimate and does not take into account the difficulty. It only takes your weight and the weight of your peers ("network") into account. The accuracy of this estimation can not be improved because the network weight is too dynamic, as is your own weight, to an extent. Use this estimate as a general guide, but it will never be accurate because of too much uncertainty.
