I upgraded the weather cat station with a new mac and mavericks 10.9.2. Over a two day period after about 10 updates to weather underground, Weather Cat quits showing new updates in the weather underground window/tab of Weather Cat. The weather underground web page shows the last temperature , etc. that was sent on the five minutes updates. This will never change until if restart Weather cat or possible wake the computer from sleep. The restart only helps for a few updates. It may have something to do with sleep nap, do I need to set the computer CPU or Hard Disk to never Sleep? Thanks for suggestion on this issue.
