Apple Seeds First Beta of Upcoming macOS Catalina 10.15.3 Update to Developers

by

Apple today seeded the first beta of an upcoming macOS 10.15.3 update to developers for testing purposes, one week after releasing the macOS Catalina 10.15.2 update.

The new ‌‌macOS Catalina‌‌ beta can be downloaded using the Software Update mechanism in System Preferences after installing the proper software from the Developer Center.


We don't yet know what improvements the third update to ‌macOS Catalina‌ will bring, but it will likely focus on performance improvements, security updates, and fixes for bugs that weren't able to be fixed in the ‌macOS Catalina‌ 10.15.2 update.

If we find anything new in the first ‌macOS Catalina‌ 10.15.3 update, we'll update this article.

The photo and music syncing from Finder is CRAZYTOWN. It basically doesn't even work at this point. Photos on iOS is totally unusable now. There's the album bug mentioned above (I assume he meant nested albums, because that's still broken), random duplications, missing Photos. Music syncing is busted too. Album art is missing. Tracks aren't syncing. I'm seriously about to roll back to High Sierra if they're just going to break features that have worked since 2005 until now. Also, has anyone noticed that if you crop a screenshot on iOS, the cropped version only persists 20% of the time? This is literally the WORST iOS/macOS release I have ever seen.

Even if I was ready to invest time into migrating off applications that are 32-bit, the bugs still make Catalina look like a hot mess. I really hope they can get their act together and squish these bugs.

I returned my new mbp 16" today. I figured if I was going to have to wait several more months for a Catalina update and graphics driver that are actually production quality, I might as well just return it and wait for the next hardware update. Perhaps by then, Apple may actually get their OS sh*t together. And it sure seems to me, lately, that iCloud services a bit unstable at times. I'm thinking the complex iCloud services interactions are starting to be an issue (inter-service dependencies and latency).
