Hey, You may see your wallet like the picture when you opening daedalus after sync block 100%.It is a bug, I believe

Just move the four folders under ~/Library/Application Support/Daedalus/DB-1.0 to other place

That four folders to other place.

You may need to wait for 1 hour to restore your ada in your wallet completly with your network is working. Don't close daedulas when restoring your wallet otherwise you will see your wallet has 0 ada like a new wallet.

One diffcult. You must move your four folder (may just two of four but I don't want to choose out the two) let your daedulas not be frozen when start(It is a bug, I believe!)
Two diffcult. Restore your wallet will take some time. I believe it due to restore your history transactions or others need some time. Don't close your daedulas when "wallet restore in progress"
