Update: the App Review Board has confirmed that my Apple Developer account will not be terminated. Sparrow on macOS is safe.

Thank you to everyone who shared and reached out in the past 24 hours - I'm grateful. Credit to Apple for reviewing the appeal and reaching the right outcome - it could have gone another way.

The deeper problem hasn't gone away: apps impersonating Sparrow Wallet are still reaching users and putting their funds at risk. I'll keep working on this, hopefully with Apple's support.

Thanks all.
