Developer ID signature, Gatekeeper acceptance, and the stapled notarization ticket passed verification.
System requirements
macOS 11.0 or later. One universal app runs on Apple silicon (arm64) and Intel (x86_64) Macs. Windows is in development; this release has no Windows or Linux installer.
Installation steps
Download the DMG
Use the versioned download above. If you already have Blob0 open, quit it before replacing the app.
Move Blob0 to Applications
Open Blob0-macOS.dmg in Finder and drag Blob0.app into Applications. Eject the mounted disk image when the copy finishes.
Open the installed app
Launch Blob0 from Applications, rather than from the mounted DMG. Accept the normal macOS downloaded-app prompt if the source is the official download.
Start your trial or activate a license
No Blob0 account or credit card is needed for the 30-day trial. If you purchased a license, open the sidebar Settings gear → License, paste your license key, and select Activate. Activation requires an internet connection.
Verify your download
Optional: in Terminal, run the command below and compare the 64-character output with this SHA-256. Adjust the file path if you saved or renamed the DMG elsewhere. A matching checksum confirms the file matches this release; it does not replace macOS signature checks.

If macOS reports that the app is damaged, the developer cannot be verified, or the checksum differs, stop and download a fresh copy from the official link. If it still fails, contact support with your macOS version, Mac architecture, Blob0 version, and the exact message. Do not disable Gatekeeper or remove quarantine to bypass the warning.
Contact supportNext: connect your bucket
You need your own Cloudflare R2 bucket and its S3 API credentials. The app stores storage keys in the macOS Keychain. Keep keys and license codes out of support messages.
