I am having a problem seeing all of my notes between my devices. Unfortunately, my primary iCloud account is @me.com. When my newer computer was set up, it was set up with @iCloud.com since @me.com is no longer around. I have the iCloud account as an alias and it works for everything but Notes. I can't figure out how to change my Notes on the Mac to integrate into my mobile devices. If I could just Airdrop, I could at least have the critical ones come through. Any advice?
As @Tetsujin said, iCloud.com, me.com and mac.com are all the same, the latter two are alias' of iCloud.
In Notes on the mac select View > Show Folders. You should now see where your notes are being saved and will have a heading for "iCloud" and "On my Mac". If you don't see "On my Mac". Select from the menubar Notes > Preferences and check the box "Enable the On My Mac Account".
You can now drag notes from the list in the middle to the groups on the left.
