I can not update from the server with appstore

Reset the device:

Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.

If that doesn't help, tap Settings > General > Reset > Reset All Settings

If that doesn't help, tap Settings > General > Reset > Reset Network Settings

You will have to re enter your Wi-Fi password.

No date is lost due to a reset.

Hi..

I was going by your original post ...

"I have the lastest ios running, I can n ot update any more from the app store"

iOS is for iPads, iPhones, and the iPod touch. Not Mac.

No, the instruction are not the same.

Exactly which Mac OS X is installed on your iMac?

This Mac.

The version is noted there.
