Rider 2026.2.2 Mac

With dotCover integration now measuring coverage for TUnit tests, the testing loop tightens into something that feels native to the Mac. Rider sits alongside your other creative tools not as an awkward port, but as an IDE that understands .NET development happens on more than one operating system. It supports .NET Framework, .NET Core, and Mono projects, so moving between a Windows desktop service and an ASP.NET Core web application on macOS doesn't require a mental gear change.

A text-heavy IDE that indexes like a modern editor

Open it next to Logic Pro or Final Cut and the contrast is obvious — this is a text-heavy, logic-driven environment. But the IntelliJ Platform underneath gives it the same indexing intelligence you'd expect from a modern editor, and the Unity support means a game project can live entirely inside one application. You get SQL and database tools baked into the IDE, so there is no need to juggle a separate client when a query needs debugging. Plugins for ReSharper bridge the gap if you still touch Visual Studio on another machine, keeping inspections consistent across platforms.

The quiet fixes that keep it running

The 2026.2.2 update addressed a macOS freeze that had been interrupting long sessions. The new AI Agent Setup widget sits in the bottom-right status bar — unobtrusive until you want it — while agent hooks give more targeted feedback after code changes. Build 262.10968.170 lands as a stable point for anyone maintaining .NET applications, services, or libraries across macOS, Windows, and Linux.

Let the indexing engine breathe before you refactor

Treating Rider like a lighter Visual Studio is the first trap. The indexing engine works differently — it wants a moment to breathe after opening a solution. Jumping straight into a refactor before code analysis finishes produces confusing results, and the fix is simply waiting for the status bar indicator to settle. Another common stumble: ignoring the built-in decompiler. Beginners often reach for a separate tool when Rider can step through third-party assembly sources right inside the debugger, which saves a surprising amount of context switching on a Mac where external .NET tooling is thinner on the ground.

Solution-wide inspections catch more than per-file checks, yet newcomers tend to run them only locally. Selecting the full solution from the inspection dropdown surfaces unused references and potential null-reference issues across an entire codebase — the kind of cleanup that prevents larger headaches once a project is shared or handed off.

The status bar widget that reshapes code assistance

The AI Agent Setup widget introduced in the status bar isn't flashy, but it quietly reshapes how code assistance feels. Instead of opening a separate panel to configure agent behaviour, the small widget lets you toggle and adjust it from the same corner of the screen where build progress lives. That proximity means you notice agent hooks more often, and the more targeted feedback after code changes means less scrolling through verbose tooltips to find a relevant suggestion. The TUnit coverage measurement through dotCover closes a gap that had been forcing test-driven workflows to compromise — if your project adopted TUnit, you previously had to measure coverage outside Rider or skip it altogether. Now the pipeline stays inside one window, from writing a test to seeing which branches it exercises.

The AI Agent Setup widget now appears in the bottom-right status bar, and agent hooks deliver more focused feedback after code edits. dotCover integration extends to TUnit tests, and this release resolves a macOS freeze that affected the previous build.
