Mimestream 1.9.5 For MacOS

Mimestream 1.9.5 For MacOS Download 2026

Mimestream is the brainchild of a former Apple engineer who helped develop Apple’s Mail app. From the outset, the goal was clear: to create a Gmail client that respected macOS design principles while remaining fully compatible with Gmail’s unique features. Unlike many cross-platform email apps, Mimestream isn’t just a simple web application. It’s built with native Apple technologies, ensuring smooth performance, system-level integration, and long-term compatibility with macOS.

While Gmail-compatible email clients aren’t exactly scarce, the vast majority use the IMAP protocol to retrieve and manage messages, meaning they can’t take advantage of Gmail-specific features like inbox categorization, labels, and synchronized signatures.

Mimestream does things differently: it uses the Gmail API, allowing it to offer most, though not all, of the features you’re already familiar with from Google’s email client. It’s worth noting that the app is written in Swift, so it will integrate perfectly with macOS and offer a much smoother experience than, for example, an Electron-based app.

Key Features:

Native macOS Application

Mimestream is designed exclusively for macOS using native Apple technologies. This results in faster performance, smoother animations, and a user interface that integrates seamlessly with the rest of the Mac ecosystem. It supports macOS system features such as Dark Mode, keyboard shortcuts, trackpad gestures, and Focus modes.

Full Gmail Feature Support

Unlike traditional email clients that use IMAP, Mimestream uses the Gmail API. This allows it to offer full Gmail support as intended, including labels (not folders), categories, conversation threads, filters, aliases, templates, and auto-replies.

Efficient Inbox Organization

Mimestream offers advanced tools for efficiently managing large volumes of email:

• Gmail-style labels with color coding
• Server-side filters that sync across all Gmail clients
• Inbox categories such as Primary, Social, Promotions, and Updates
• Snooze to postpone emails until a specific time
• Unified inbox for managing multiple Gmail accounts

Profiles for separating work and personal life

Profiles allow users to group accounts by context, such as Work or Personal. Each profile can have its own notification settings, work hours, inbox appearance, and behavior, making it easier to stay focused and set boundaries.

Advanced Search

Mimestream supports Gmail’s full search syntax, enabling precise and fast searches across large mailboxes. Searches behave exactly like they do in Gmail on the web, delivering accurate and consistent results.

Privacy and Security

Mimestream connects directly to Gmail using secure authentication and encrypted connections. Email data is stored locally on your Mac, and no third-party servers are used to process or store messages.

Performance and Reliability

As a native application optimized for macOS, Mimestream remains fast and responsive even with large inboxes. Synchronization is efficient, and the application is designed to handle heavy email workloads without slowing down.

What’s New in Mimestream?

Performance and Reliability Improvements

Recent updates focus primarily on speed, stability, and efficiency. Mimestream now uses smarter cache management to reduce disk usage and improve sync performance, especially for users with large mailboxes. Overall responsiveness has been improved for inbox loading, search, and message rendering.

Private Push Notifications (Labs)

A new experimental option introduces private push notifications. This improves the speed and reliability of notifications while keeping email data more secure and minimizing reliance on third-party notification services.

Improved Sign-In and Account Activation

The sign-in and activation process has been modernized with a more reliable authentication flow. Account setup is smoother, more secure, and better handles edge cases during sign-in.

Updated macOS Design Support

Mimestream has been updated to better align with the latest macOS design language. Visual enhancements ensure a modern and consistent application that aligns with system UI changes, including an improved appearance in both full-screen and windowed modes.

Improved Swipe and Gesture Controls

Swipe actions in the message list are now more flexible. Users can customize gestures such as archive, delete, or mark as read, making inbox sorting faster and more intuitive.

Visual Inbox Improvements

Sender monograms now display uniform colors, making it easier to visually scan the inbox and recognize messages at a glance.

Attachment and Message Rendering Fixes

Updates include improvements to downloading and managing attachments, as well as fixes for font rendering and message display. This results in fewer errors when reading or working offline.

Stability and Bug Fixes

Numerous minor fixes address issues related to synchronization, snoozed messages, login edge cases, and UI behavior. These improvements, taken together, make Mimestream more reliable for everyday use.

Ongoing Focus

Current development is focused on refining existing features, improving macOS compatibility, and optimizing the overall polish, rather than introducing major new workflows.
