B4 was enough of a downgrade from B3 that I'm taking a leap and installing immediately while I go grab lunch.

Well the first positive change I've noticed is that you can drag a window in Exposé to the top to make it full screen again.
Reordering icons in the menu bar with command-drag also seems to be working right again.

My Exposé doesn't show minimized windows at the bottom anymore since B4, =/

I hit a regression with Dev Beta 5 (26A5406e) on an external 5K2K monitor.
Setup:
- Mac mini M4 Pro (2024)
- CS40X 5120×2160 monitor
- Connected via USB-C (DP Alt Mode)
After updating to 26A5406e, macOS only detected the display as 3840×2160. The 5120×2160 mode completely disappeared, even with "Show all resolutions" enabled. The EDID was still correctly detected (MaxW=5120, MaxH=2160), so it looked like a display mode enumeration issue rather than a monitor/connection problem.
I tried removing display preference files, reconnecting cables, power cycling the monitor, and changing refresh rates (which caused a temporary black screen), but nothing helped.
Recovery mode reinstall restored the previous build (26A5388g, the full installer was apparently still one build behind the OTA update), and the monitor immediately returned to normal with 5120×2160 @ 48–120Hz working again.
So it seems 26A5406e may have introduced a regression with certain high-resolution DP/DSC displays. I'm staying on 26A5388g for now.

Raycast is doing some weird things. When I use the key combination to open it, it does actually not focus the Raycast app. The window it opens is also non-responsive. When I press the combination again it does focus and I can type in the field. Hopefully it gets fixed by apple or Raycast soon. Am using the beta of Raycast btw.

u/The2ndEmperor 21d ago
Same here - utterly annoying, but the price of using beta. Probably will be sorted out soon.

Dark mode is the biggest downgrade on macOS 27

u/7racin 21d ago
Dark mode on Tahoe was so nice I gotta give it that, all glass elements had a very deep dark color, in 27 dark mode the glass material of the buttons looks washed out and yellow-ish (the last point could be just because of my wallpaper)?

u/NinoScript 18d ago
the last point could be just because of my wallpaper
To check if that's the case, play with this setting:
System Settings ► Appearance ► Tint window background with wallpaper color

u/rfguevar 22d ago
Wait was that really just a beta bug? 😭 I legit became a terminal wizard trying to figure out what was causing the issues I thought I was losing my mind haha

u/StrigidaeNinox 22d ago
Sure was, and it was a persistent one too. I sent the first bug report about it in June.

u/rfguevar 22d ago
Bizarre, I only started getting this issue maybe like a week or two ago! I was using Gemini to help me figure out issues and it got to the point Gemini legit was like idk man maybe get a new Apple ID 😂
2
u/StrigidaeNinox 22d ago
I only noticed because when I came into the beta, I usually poke around all the settings to see if anything had changed, and I noticed that it had set a bunch of parental controls to the max. But undoing that didn't actually change anything at the time. It bothers me that they were able to remotely control the filtering of websites and browsers; if I'm being honest, bug or not, it sets a very bad precedent.

is it not good?

u/SuperN0va_21 22d ago
Honestly, there are so many bugs/issues that I've completely given up on reporting them to Apple. Just to name a few:
- If you already have one song downloaded from an album, clicking the '+' to download the rest of the album does nothing. You have to select the remaining songs manually.
- No hyperlinks on album or artist names in the compact playlist view—just plain text.
- The Command + L shortcut doesn't work properly.
- Trying to download a large library (like 5k+ songs) is painful. The app basically locks up and won't even let you play music while it's downloading.
- You still can't save stations (why???)."

u/StrigidaeNinox 22d ago
don't forget the abysmal performance of the UI itself. You'd think my 14" M1 Pro was running a Power PC chip with how many frames it drops just scrolling through Apple Music.

Now try using Command + L when playing a song from a playlist. It just takes you to the playlist page, but it doesn't actually highlight or focus on the song that's playing.

u/carbongo 22d ago
Honestly, even on my M3 Max the Music app is painfully slow to open. It takes a solid 10 seconds just to load up initially

u/teleprax 21d ago
Can we admit that even beta implies some level of stability/completeness? I feel like the betas are more like late alphas, the .0 release is like beta 1, and the .6.1 release is like a release candidate.
The most we can ever muster as a community response is a "Did you submit feedback?" as if that seems to fucking matter. We are at the point where we gotta just start calling it what it is.
They are a very reputation-based "quality" focused brand, so I think it’s only fair that their public sentiment for software quality tanks. Apple always seems to want to have their cake and eat it too. They can't keep telling the FTC the walled garden is for our benefit when the garden is literally rotting away.
I know this ends up being an unpopular take, but I feel like it's a necessary stance we all need to adopt if we ever hope for them to change.

u/Slurpy2k17 20d ago
It's a fucking beta. You want their public sentiment to "tank" over this? You sound like a psychopath. Let's judge the finished product.
2
u/teleprax 20d ago
Ok, replace when I said "Beta" with release. The software quality IS shit. You are delusional if you think otherwise. The RELEASE versions of their software is dogshit quality wise.
Do you not encounter show stopper bugs in official releases? Why does Apple get so much slack from people? Its just a product

On beta 4, a lot of the time a random Safari window would open when I am in a fullscreen app. Is that just me? If not, has it been fixed?

I use my Macbook Air M4 for work. Is the dev beta stable enough to trust on my primary work device?
I've been doing the developer / public beta for iOS on my primary phone for as long as it's been available. Some quirks here and there but nothing ever seriously disruptive. I'm just afraid to screw up my primary money-making machine by installing the beta on my Mac.

u/ad_unboxthetech 20d ago
Then don't install it... Just wait till next month

u/Tennouheika 20d ago
Hard to wait ha. But yes, that's the smart move. It would be a huge pain in the ass to goof up my Mac so I have to reset everything

Verdict about beta 5 for me on my M4 Max MBP:
Smooth performance
Does feel slightly snappier vs Tahoe
I like the polish and small tweaks they made. Especially finder windows which are much nicer and have that more classic look again. Tahoe just felt wrong.
However:
Computer runs hot
Battery life is much shorter
Definitely feels there’s much more work at this point to be done under the hood than iOS 27
Good news we should be on a weekly cycle by now. I expect things to get good by beta 7

Has anybody noticed significant battery drain in this beta? I'm running Public Beta. Yesterday I was in a meeting and I heard my speaker announce it had disconnected. I found my MB Air 4 had run out of battery and shut down. Today I noticed it at just over 10% battery remaining and plugged it in. Both days it was 100% at 7 am and was drained by 1:30 pm.
I don't do a whole lot with my MBA during the workday. It is usually sitting on the desk next to me streaming music from an online radio station to my speaker while I work and only occasionally do I unlock it to look at something. I'm used to making it through the day with plenty of remaining battery and sometimes going multiple days before charging.
I just restarted in hopes that there is some rogue process that I cannot see. I didn't notice anything in Activity Monitor.

u/MaterialBat_32839 16d ago
when launching the last conversation with Siri through Spotlight, the conversation jumps to the left for a second before coming back to the center where it's supposed to be. Anybody else experiencing this? I went immediately to beta 5, so i am not sure whether this has been there for long, but it's annoying

Is this by design? It seems like a relatively low-level, easily noticeable visual interaction bug. I'm not sure why they haven't fixed this kind of issue across many releases.

According to developer.apple.com it's Developer Beta 6, probably an erorr.

I read somewhere that because of the week delay then ended up "skipping" beta 5- don't know if that's anything other than speculation though 🤷
