Hi thanks for your reply , I dont think that is completely true.
New update confirming issue is not the actual Keyboard hardware .
It is 100% the battery monitor software.
And 100% apples fault .
Not happy ,
5 years ago , I had nothing but Praise for apple ,
now with my £7k investment I'm not so sure I made the right choices.
Apple have in effect broken all wireless keyboards / devices that are out of warranty.
So In effect no more buying a used keyboard etc as a secondary etc ,
they will all be affected by apples drivers. "Sounds more like HP" than apple.
The driver controls the keyboard / device battery report.
100% tested and works :-
Macpro 5,1 Mavericks reports keyboard batteries Low , Constant Nagging. "STFU!!".
Check in System Prefs KB , reports 19% etc .
Remove battery lid , wait for disconnect.
Replace battery lid only , reconnect 99% battery level.
Apple are releasing shameful software with Lion , M Lion and now Mavericks , leaving each broken in some way and a full reinstall needed to "Upgrade" to the possibly new we all hope working version?..
i.e look at console on a new Maverick install on first login it is simply broken.
FCPX & Logic Pro X - Apple ditch industry standard software and its user base and replace it with including the Lack of any 32bit plugin support running back since at least 2005 for intel plugs and then junk it full again of bugs that it "All software" cant be used even on a High end MacPro tower with 32GB ram.
FCPX is like learning to skate on the surface of a balloon without popping it.
It is 100% Software and 100% Apples fault.
I have no respect for Apple anymore as Totally fight against my computer daily to accomplish any task as it stands, and now even typing on the keyboard is costing me hours of down time..
Solution , install Snow Leopard , Final cut 7 / Logic Pro 9 / or a supported AVID / Protools configuration.
Forget about anything new as it is a waste of time and money / or does not work.
In my experience if it does not work out of the box , it never will.
The End.
I will be calling Apple in the next 5 mins , to demand they Post me a new Keyboard and Magic trackpad ,
free of charge. Im not willing to go to a store at this point , they can mail it to me.
The Keyboard has disconnected and reconnected at least 7 times while writting this.
