Apple Seeds Second Release Candidate Version of macOS Big Sur 11.5 to Developers

Apple today seeded a second release candidate version of an upcoming macOS Big Sur 11.5 update to developers for testing purposes, with the new update coming one week after the release of the first RC version.

macOS Big Sur Feature Blue
Developers can download the ‌‌‌‌macOS Big Sur‌‌‌‌ 11.5 beta using the Software Update mechanism in System Preferences after installing the proper profile from the Apple Developer Center.

macOS Big Sur 11.5 introduces an update to the Podcasts app that allows the Podcasts Library tab to show all shows or only followed shows. It also addresses an issue that could cause music not to update play count and last played date in the library, and a bug that caused smart cards not to work when logging into Mac computers with the M1 chip.

what does "good enough" mean? I upgraded my iMac from Mojave to Big Sur ~ 3 weeks ago no problem, only issue that I see is Finder CPU usage ~ 40% for no apparent reason, that's why I've been waiting for .5
Other than that it works great for me
By "good enough" I mean a stable release with no sudden / obscure kernel panics or weird compatibility issues. In a nutshell, a solid product which won't make me painfully regret my decision to upgrade.

But I guess it's still a bit early to tell if you did that just three weeks ago. Anyway thanks for the feedback ?

Actually I had been running Bis Sur on my MBP for 10+ months incl public beta, but I just traded that in 2 weeks ago…
I never ran into any issues running Big Sur myself, not saying others have the same experience
