Apple has seeded the release candidate of macOS Big Sur 11.5 to developers for testing. The release candidate comes one week after the release of the fifth macOS Big Sur 11.5 beta.
The developer build of macOS Big Sur 11.5 can be downloaded through the Apple Developer Center and once the correct profile is installed, succeeding betas will be available through the Software Update mechanism in System Preferences.
macOS Big Sur 11.5 brings an update to the Podcasts app that allows the Podcasts Library tab to show all shows or only followed shows. The update also addresses an issue that could cause music not to update the play count and last played date in the library, as well as a bug that caused smart cards not to work when logging into a Mac with an M1 chip.
