-On Apple Silicon Macs running macOS 26 (Tahoe) or later, the `sapphire-localnet` Docker
-image may hang on startup with peer authentication errors (e.g.,
-`chacha20poly1305: message authentication failed`).
+Rosetta must be **enabled** in Docker Desktop for `sapphire-localnet` to work
+on Apple Silicon Macs. QEMU emulation is not supported. Go to
+`Settings > General > Virtual Machine Options` and verify that
+"Use Rosetta for x86_64/amd64 emulation on Apple Silicon" is checked (this is
+the default).
 
-This is due to a bug in Rosetta 2's x86_64 emulation. The workaround is to
-disable Rosetta in Docker Desktop settings, which makes Docker use QEMU
-instead.
+Make sure to pull the latest version of the image:
 
-Go to `Settings > Virtual Machine Options` and disable
-"Use Rosetta for x86/amd64 emulation on Apple Silicon".
+`docker pull ghcr.io/oasisprotocol/sapphire-localnet`
