Many people have problems with restoring byteball backups sized > 4gb. I just build the wallet with patch provided in github https://github.com/byteball/byteball/pull/164. I think it will be preffered to transfer your funds to exchange and wait for the next stable version from Tony. And only then transfer it back. That because your backup may corrupt due to database migration. Enjoy it.

How many people will use a fix published by a random dude with no posts history? Ever thought of that?
P.S. You can patch your installed Byteball.app by yourself. Just replace the "unzip" library in the "node_modules" to that "https://github.com/byteball/unzip". The repo is official and is supported by Tony.
