Is my older MacBook Pro with the Intel core duo processor compatible with iCloud? This machine cannot run OS 10.7 Lion because it doesn't have the core 2 duo processor. I'm running Snow Leopard. My problem is I already upgraded my MobileMe account to iCloud on my iMac desktop (running Lion) and my iPhone 4 (iOS 5). All my data is now in the cloud and I'm unable to sync to the MacBook Pro. I think I know the answer... and it's not good.
I found this solution for syncing iCal on another thread:
Pass this to all. icloud and ical works with snow lepoard.
Go to iCal preferences.
Set up new account.
