Software updates, Itunes store and App store, do not work
I have a macbook Pro using Mountain lion 10.7.5. Itunes store, Software updates and App Store all fail to connect. Itunes tells me to check my connection.
When I attempt to access any of these on my G4 ( still running Snow Leopard 10.6.8) using the same network all is fine. ( I have copied the network info as well as access, security, sharing...
I have never had success with updates on the macpro but then I only got a serial number for it today. ( It is 18 months old and the store forgot to assign it when I had it repaired 5 days after purchase.)
I think I have tried EVERYTHING. Date in settings etc. I have followed all teh how to sites for ITunes store. I really need to update this. I would install Maverick but it is only available on APPs store which also does not conect.
