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.

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.

I'm not able to install the latest beta. It's trying to update me to Monterey, giving no other choices. I even re-install the utility from the developer website. And the Monterey config utility is different. I made sure that I was re-downloading the Big Sur version.

UPDATE: Seems fixed. Now giving me the choice of downloading the Big Sur beta.

Wonder when (or if) they'll fix the lack of two or more external monitor support for M1 Macbooks

Fix something they never indicated would ever come to the M1 series MBP? That will require new hardware and likely will help Apple sell more new generation M1 series MBPs later this year. It seems a hardware limitation of the current M1 series

yep. Anyone that buys an M1 I think is stuck with this limitation.

This is why I returned 2 M1 Mac mini's. Lack of ports and hardware limitations.

AND not being able to hook up external graphics cards in an external box.

I mean come on. Your already loosing support to boot to Windows. Now your stuck with on board Graphics.

What you buy in terms of upgrades from APPLE your stuck with.

LIKE AN IPAD or IPHONE.

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.

1. Did they fix the flakey operation of external Apple monitors on Intel MacBook Pros?
(Some report the monitors are not recognized as being connected.)

2. Did they fix the flakey operation of USB ports on the rear of external Apple monitors?
(Apple keyboards and mice are not recognized as being plugged in there.)

3. Did they fix NAT (Network Address Translation) which they broke for VMware in BigSur?
(It just doesn't work.)

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.

Hey, good news:

Apple has probably noticed that external displays don't work so well with the M1 Macs and has probably completely disabled support in this build, no reboot/shutdown/reconnect helps anymore. The probability is high that it will be released this way because Apple calls this stable.

Tell that to intel Mac users.

I really hope they are about to do something about the display thing, because it's starting to get tiresome now.
Out of the 5 displays I have tested (three monitors, two TV's), only one monitor is working reliably.

Not what I expected from Apple.

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.
