With our recent update to Fission, all Rogue Amoeba applications now support MacOS 26 (Tahoe). If you’ve updated your Mac to Tahoe, just download our latest versions to get going.

Consider Delaying Your Upgrade

However, while our products are ready for Tahoe, Tahoe itself comes with a few caveats. It’s always wise to be cautious in upgrading your Mac’s operating system, but this year, there are particular reasons to take things slow.

Unfortunately, Tahoe contains two significant bugs which can lead to lost audio. We’ve created a support article which provides full details on the problems, as well as information on working around them. Click below to read:

The necessary fixes for both of these bugs must be made in a future update to Tahoe itself. We’re in contact with Apple about these issues, and we’re hopeful fixes will arrive in the near future. We also expect that most users have setups which will not run into these issues.

Still, if you’re able to delay upgrading your Mac to Tahoe, we currently recommend doing so. Sticking with MacOS 15 (Sequoia) is a sure-fire way to avoid problems at this time.

More to Come

As soon as new betas of Tahoe arrive, we’ll be testing them to determine when these OS bugs have been fixed. We’ll keep you apprised via this blog, as well as our always helpful Status page.

Of course, while we await further MacOS updates, we’ll also be busy improving our own apps. We’re hard at work on some big new features which we’ll be releasing in the months ahead.

For now, though, we’re pleased to have completed the work to support Tahoe across our product line. As always, to ensure you have our latest versions, download right from our site or select Check for Updates from within the app.

Today, we’re releasing a free update to our audio editor Fission. You’ll find a lovely interface refresh in the new version 2.9, as well as a handful of small bug fixes and support for Apple’s forthcoming MacOS 26 (Tahoe). Read on for more details, or update immediately by selecting “Check for Update” in the Fission menu.

Look at What’s New

The first change you’ll notice with the new Fission is its new app icon. That icon has been updated in accordance with changes Apple has dictated in MacOS 26 (Tahoe).

Once you open Fission, you’ll spot many more changes. In fact, the entire application has been given a virtual fresh coat of paint. You’ll spot updates to the Start window, the editing window, and the Batch Converter.

We polished many parts of the app for this update, while still making sure Fission’s powerful functionality stays at your fingertips. Most notably, the light theme has been refreshed to lean into the app’s gold coloring. As well, art assets throughout the app have been improved, to make Fission look better than ever.

Fission also works better than ever. There are a handful of minor bug fixes in this free update, plus some improvements to accessibility for our VoiceOver users. Of course, as always, we’ve got comprehensive release notes you can check out.

Initial MacOS 26 (Tahoe) Support

Apple has announced that the new MacOS 26 (Tahoe) will be shipping on September 15, 2025. With this update, Fission now offers initial support for Tahoe. As you can see on our helpful Status page, there are no known issues when using Fission on the new OS. Whether you’re already running Tahoe, or you’re planning to update soon, Fission is ready.
