I do not know either if you misspelled your seed phrase. But we are human beings. It can happen. In my case I had the seed phrase printed out, so no chances it was misspelled. Still, I was not able to get access to my account. Do not thank me. I know what difficult situation you are living. My father has a cancer on very advanced stage, too. It’s tough.
the coins on the first account have not been taken or stolen they can both be seen on eth and bscan.
It is good thing.
As I have no Mac, I just copied the steps from support. apple. com/en-us/HT204215. But maybe it is not clear.
Try this instead:
1: Open Finder on Mac screen
2: From the Top menu bar , click on the Go option > Go to Folder… Enter this path :
~/Library/Application Support/MobileSync/Backup
and Click on Go.
If you have iTunes installed and have the backup, maybe there is a data that can help.
Lets try this first.
If there are no backups for your iPhone, there is one more option left. It’s very complicated. It calls BTCRecover tool. It may work in the case the seed phrase was misspelled with maximun 3 mistakes/ wrong words. In my case this tool didn’t work (I tried), as the real/hidden seed phrase was totally different from my usual seed phrase.
