iPod touch Removing apps from iPod to Itunes??

[booty]

Hi, I hope someone can help!

I've had Ipod touch for some time. All apps were loaded on with old windows laptop but since moving to mac itunes doesn't recognise the apps on ipod!!

I have Touchcopy and Music rescue but these do not seem to include apps from ipod to itunes!!

I have bought more apps on mac but when I go to sync it advises I will lose all old apps from ipod....

Can anyone offer any advice please.

Thanks.

Very kind of you... but tried this method and for some reason doesn't work! But thanks for your 2 seconds of time.

You need to use the same account that you used before or authorize the new computer for each account you have.
