# Thunderbird vs Apple Mail Published January 1, 2026 · Updated August 10, 2026 Thunderbird and Apple Mail are both email on a Mac, so the pick depends on workflow.

As of November 2026, both install with brew install --cask thunderbird and brew install --cask apple-mail. August 2026 keeps Thunderbird and Apple Mail as complementary winners.

Intel Macs do not get those Intelligence features. ### Which is better for OpenPGP? Thunderbird. It remains the practical FOSS default for OpenPGP email workflows on desktop. ### Can Thunderbird do Microsoft Exchange now? Yes - built-in Exchange support arrived with the Thunderbird 140 ESR generation and continues as a relevance point into 153.x. Verify against your organization's policies. ### Does Apple Mail work on Windows? No. Apple Mail is Apple platforms only. Use Thunderbird or another client for Windows or Linux. ### Which uses less battery on a MacBook? Apple Mail typically. Thunderbird is fine on modern hardware but heavier with large local stores. ### Do I need iCloud+ for Apple Mail?
