Apple Seeds Third Beta of macOS Big Sur 11.5 to Developers

Apple today seeded the third beta of an upcoming macOS Big Sur 11.5 update to developers for testing purposes, with the new beta coming two weeks after the release of the second macOS Big Sur 11.5 beta.

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 may be a more minor update focusing on under-the-hood performance improvements and bug fixes for issues that weren't able to be addressed in the macOS Big Sur 11.4 update. No new features were found in the first two betas.

PLANNED OBSOLETE, GET A NEW ONE. NO UPGRADES FOR YOU.
Apple beat an industry record last year by supporting the 6S for 6 years, now they just beat the industry record again with iOS 15.
Meaning the iPhone 6S, that I bought in September 2015, will be updated until September 2022. A whopping 7 years.

Sorry but I fail to see where the planned obsolescence is.

Wonder when (or if) they'll fix the lack of two or more external monitor support for M1 Macbooks
This isn't a software limitation. There's nothing to fix on these particular models.

Well, my mid-2014 MBP missed the cut for Monterey, but should get security updates for another two years. Nine years isn't bad, and even then it's not like the machine suddenly stops working. Having said that, I do realize that some newer models missed as well.

The mid 2012 MacBook Pro actually boots Monterey. Most likely the same with your 2014. Enable a simple flag to disable the kernel compatibility check, and voila, Monterey will boot.

Given that the monterey x86 kernel schedules threads properly on the mid 2012 cpu cores, the graphics card kext still loads, what technical reason is there to have completely abandoned support? You can’t tell me planned obsolescence isn’t part of it. The only thing that doesn’t work out of the box is Wi-Fi, and I didn’t check to see if Bluetooth works or not.

The fact that Monterey booted just fine on my mid 2012 kinda pissed me off to be honest. not clear why it’s not supported, even if it doesn’t get all the bells and whistles like universal control or side car or whatever.

Well, I have an OWC Thunderbolt Dock, and I got, somewhat out of the blue, a request to do some speed tests and pass along my system information this morning. Apple releases beta 3 of macOS 11.15, which still has no stated feature updates or changes. These two things make me think perhaps they might be doing something in that area, minimally.
