BucketMate S3 client on macOS

MinIO community edition is archived

The minio/minio repo went read-only in April 2026, prebuilt binaries stopped in October 2025, and Homebrew's minio formula is deprecated. Existing servers keep working, and BucketMate still connects to them. Source

Made for MinIO.
Not just any S3 endpoint.

HTTP on localhost

Connect to http://localhost:9000 on Mac. BucketMate warns that HTTP is not encrypted, so keep it to trusted networks.

Versioning without mc

With the admin UI gone, BucketMate is a GUI way to turn on versioning and auto-delete old versions.

Local next to cloud

Keep a dev MinIO next to AWS S3 or R2 in one sidebar, grouped in workspaces.

MinIO errors, decoded.
What they mean and how to fix them.

x509: certificate signed by unknown authority

The server uses a self-signed or mkcert certificate.

Trust the certificate in Keychain Access, or use http:// on localhost.

SignatureDoesNotMatch

A reverse proxy or tunnel rewrote the Host header.

Pass the original Host header through the proxy.

HTML instead of XML

The connection points at the Console port, usually 9001.

Use the S3 API port, usually 9000.

MinIO and every other bucket.
One window.

MinIO S3 compatibility notes

Path-style by defaultSet MINIO_DOMAIN only if you need virtual-hosted URLs.
Match the schemeUse http:// or https:// to match how MinIO listens.
Plan a migrationThe community edition gets no more updates. Keep an eye on security fixes.
