Same for me. The M1 MBP has much more hearing range than the M1 MBA.
Did you meant to say other way around? :)

And I'm working in the music business and know what i am talking about. So maybe a faulty MBA or something else is kind of weird?
I'm not audio professional or anything but to my ears MBP vs MBA was pretty clear difference that MBA sounded better and fuller. Sure MBP was kinda balanced sounding but with lack of bass.
Also this can be seen in Notebookcheck measurements (especially looking hearing range measurements) and that they gave more points for MBA speakers.

but even then: the air has an easily changeable battery while the pro battery is glued in. Battery service costs almost twice and if you can hold a screw driver you could do it yourself with the air.
I think this is real strong point of MBA after some years once Apple determine it as vintage model, so by that time MBP's are practically trash with nonremovable battery while MBA's can still get 3rd party batteries. Otherwise it does not really matter much until that and I would rather take Apple original battery replacement.

I was not aware that the MBA had a non-glued in battery, that's awesome. That fact is tilting my favor more towards the MBA as I would like to hand the machine down when the 14" MBP is released. A more affordable and easier battery replacement down the road would be appreciated!

this is pretty awesome! It will be the longevity model

Always found that annoying that glued down batteries had to have the entire bottom case replaced... wasteful and playing lottery with all the other bottom case components.

Yea and you have to depend on Apple. You will have battery service for a time but when the machine hits the 10 year mark, this is not uncommon for Apple laptops then what? If Apple declares it obsolete there won't be any service anymore. But with the Air you can always go to Amazon, buy a cheap China battery and use it as a plugged in music station or something like that. I don't mind that you can't upgrade the ram or the SSD but what bothers me is if you can't upgrade something that is considered an expandable part. Like batteries. We all know that they will die sooner or later. So why glue them in?

Got a M1 Silver base MBA two days ago

Loving it. The screen isn't perfectly uniform, but its pretty dang good and looks way better than my 2020 i5 MBA I still have because I am waiting to receive the trade in box for it.

And I'm always kind of OCD about screens. But I just fired up my i5 to take another look, way less bright at half brightness mark, text not as crisp, looks more washed out being sRGB spec vs. P3 on this and in general, and I swear it might be even less uniform left to right than this one and I've used it all year since not long after its release haha, and was slightly superior panel to the previous unit I had before that (got a better deal for the bumped i5 config than i5 BTO so had two units to compare side by side of the early 2020 MBA) and. And the whites seem cleaner overall on this one, vs. more of a red bias on the i5.

I also think the keyboard feels better, though that may be individual keyboard manufacturing variation. it just feels nicer than my i5 2020, but maybe being whaled on for months changes the feel - don't think so though. I think there are slightly different feeling keyboards in a subtle way

Don't think I'll be playing the panel lottery this go round, I wouldn't be surprised to get one that's got glaring flaws or things I don't have as an issue on this machine

When I run trailers that have lots of blacks, the blacks are solid and not shimmery and don't really convey a distinct tint.

Could you test yours as described in this thread?
So far you seem to be the first not seeing red glow on the right. Before I or others suffering from that run exchange our units in hope to get rid of red glow in this test could you please make sure. Also would be nice if you would list your serial numbers first two and 5th character if yours turn out to be free from this issue. Thanks.

what is the exact test ?

You guys see red even on blacks watching trailers ?

starts FV I’ll get the 5th character in a bit

I think a lot of people here go looking for problems, instead of enjoying the computer. If I can't see a obvious problem during normal usage, I am not about to run a bunch of tests to to show something that doesn't readily show otherwise, and then complain to Apple that the laptop isn't perfect and start a return.

I like to know the limitations of the machine. I can see the issue. A slight redness in the upper right corner of the display when at 75-100% brightness on a completely black screen. I checked light gray, gray, dark gray, white, red, green, and blue screens and saw very good uniformity on those screens so for most situations, the screen is excellent. In one corner condition, it has a slight uniformity defect. I haven't seen it manifest in normal use. I certainly wouldn't return the notebook because of it.

so this is a YouTube video with black bars (Jonah Hill 'best of' in Wolf of Wall Street), at 100% brightness in darkness.

Didn't see it with Soul trailer either (the blurry one of the four characters is to show you the black parts of the screen with a higher exposure photo).

Do you see a hint of red in the black bars? I don't, my camera doesn't either. OP described being able to see it in this situation

FV, fifth character T in serial #

also 25% grey scale from https://www.eizo.be/monitor-test/ at 100% brightness in a dark room, indicated by the second photo attached (light in other room, but near pitch black where I am). The right is slightly less bright, but not as much as the camera makes it appear. and as far as I can tell, no obvious pink tinge like OP's photo.

the last two blank screens are 100% brightness in darkness and lit room, on a white screen which looks way brighter and whiter in person so ignore that and ignore the artifacts, that's the camera - and again, not what my eye is seeing but to give you some idea of uniformity. Let me know what ya think

I hate grey scale tests, every screen has imperfections but still looks pretty good to me especially compared to others in this thread

line 17 in Color LCD profile in settings-> display yields that it's Model A03C

@thadoggfather what they are doing is first using a completely black background, which I think the Eizo test gives you an option for, in a completely dark room with auto brightness off and brightness set to 100%.

with the naked eye, I can see the red glow, but then taking a picture of a pretty dim screen then exaggerates the effect.

in the conditions that you took the photos I agree with you, you can’t see the problem. I think the issue is being blown out of proportion in normal use conditions. I am happy with my screen, and I would doubt that if I took it in to Apple they would agree it is a problem.

It is possible that some here have slightly more pronounced red glow issues than I have, but given the limited number of people that see it as an issue, I don’t think it is a widespread concern.

This isn’t even remotely what I’m seeing with my naked eye at 100 percent brightness with a black desktop, no red on that or watching trailers and the light leak stuff at the bottom is something only camera is picking up looks like the LED backlight lol

what the camera is picking up on the right is a hint of less brightness diffused on right side

but again not even REMOTELY what the naked eye sees, not representative the previous photos are. And not even resembling OP’s hideous photo, where the right side and top edges are clearly a defined red

Maybe the 12 pro camera and a black wallpaper on these P3 panels is like looking at a 2% greyscale on OLED in pitch black, on crack sixth sense style



To be honest if I could see distinct red watching trailers it would bother me. Blown out of proportion or not

This thread remind me of my first Mac.

2007, first laptop I ever owned, first Mac. MacBook Pro 15' (it was before the unibody).

Discovered MacRumors, I was here every day waiting for my MBP to arrive.

There was a big thread about "yellow-ing issue" in the lcd panels. Kind of a yellow-ish slighty dark shadow on the bottom half the screen. I would have never noticed it, but here I found images I could put on my brand new screen, Dark grey image with little white box top and bottom of the screen. With this, you could see that the box at the bottom was slightly more dark and yellow than the one at the top.

"OMG My screen isn't absolutely perfect ! It's Apple, they should ship perfect screen, unnacceptable".

I got "Macrumor-Defect-Fever". I ultimately brought the machine to an Apple Store, showed the image. The genius agreed for a screen repair. Waited for a week without my laptop. When I got it back, the new screen had the same issue ... as did almost all of them in store. Also, the new screen assembly was a bit "misaligned" when closed compared to the rest of the laptop. (It was before the unibody macbooks we have today. The build was way less precise.)

Anyway, the screen was fine and I never really noticed it except when I looked actively for the "yellow shadow".

And then I decided : no more Macrumor-Defect-Fever again.

Could you just take a photo of black full screen image without anything else on the screen in mentioned conditions so we could finally put to rest this issue? Because in your photo you have those bright icons just where the possible issue would show up, so your test was not helping and that would make it impossible to see with bare eye likely, or make it extremely difficult. It is like showing a wound with bandage on to the doctor but refuse to remove it. :) But even in your photo this difference on the right edge is noticeable, so it gives a hint it might be the same if tested the same way...

Anyway, yours is from FV factory, while other in this thread are C0 I believe, so if you can confirm and show in the photos, your unit does not have this red glow in this situation, then it might be worth for others trying to hunt for FV (I believe Foxconn factory) unit .

Serial numbers first two characters. In this model C0 or FV, maybe even something else but those two I have seen with my previous models too. C0 is Quanta. Actually I'm not fully sure about FV but pretty sure it points to Foxconn as those beginning with F usually do.

please try to ignore the mouse cursor at the bottom

this is a black wallpaper at 100%

to my naked eye, the right looks a bit darker but I didn't see any red at all

and this was the best I could try to capture it even though, again, this isn't what the screen looks like in person.

I don't see the same red on the edges where the icons were in the previous photo on this like the original post

Also what are your thoughts of the post where I showed trailers running, etc? Looks good right? An affected panel wouldn't pass that simple test with black bars ?

Hard to say for sure from the photos but the pattern on the right side looks pretty identical to all others in this thread.
Sure camera sees things different way (image is close to even black or dark gray) and mine does not look like in the photo of the first message in this thread but the red glow on the right upper corner can be noticed in a dark. Again this is something that you must give your eyes a while to adjust the darkness and such, I'm so used to find issues with displays, I find thing like this fast but I know for some peoples you have to give coordinates and tell what to look for to see issue like this (I'm not talking about you but saying in generally this is what I have learned). :)

I can see that in mine with black bars also in mentioned conditions, not sure they show up in the photographs I did not try.

Anyway, yours look based on pattern similar as other but if you absolutely can say for sure there is no red tint noticeable in the dark using full black screen with 100% screen brightness (make sure it is really at 100%) and True Tone on (my photos is like that), I guess we are going to see a lot of peoples in this thread exchanging their machines but hopefully not in vain in case it turns out to be what I speculated about...

Yeah I did not see red at all watching trailers

that would bother me and that is a real world test IMO

my eyes didn’t see red either

I’ve had iPads that have had a red shift on whites, blacks , everything thrown at it and I hated it

this doesn’t seem to be the case for me. Ymmv

And you actually watched them in a dark with TT on and screen at 100%? Because there have been those in this thread previously too who first say theirs is perfect and then found out they had AB on similar on and when taking photo the same way it looked like that and there was red on the right side.

I’ve had iPads that have had a red shift on whites, blacks , everything thrown at it and I hated it
Yeah, I would not tolerate shift in whites at all but mine is perfect there. Passes even demanding "tree" test image easily. Screen is more uniform in bright than my MBP was.

this doesn’t seem to be the case for me. Ymmv
Hard to say for sure since the pattern in your photos is there and your last photo looked almost identical to others.
Just for fun I put here photo taken with my 12 Pro (My first photos were taken with X).
See they are nearly identical. I can't remember camera setting for this but I think it was not using long exposure.
I guess to make your would help if you can double check all settings and try with TT on and take few more photos with different camera settings (like default long exposure and then without it and make sure your camera is in the middle of the screen. Red goes away in mine if I just move say 5" to the right from the middle still looking straight at it).

So dunno what to make out of this since you say there is no red you can see in any mentioned conditions.
I hope we do not run to exchange our machines in vain.

Since in your photos, there is obviously darkness in the upper right corner in the movie scenes, like in the scene with Mr. Hill the corner is much darker, so something funny is going on there still...
Also yours might be with the same panel as per info you posted but I think that code does not really tell which manufacturer was, just panel generation. Have you checked what panel is actually using this terminal command?
ioreg -lw0 | grep "EDID" | sed "/[^<]*</s///" | xxd -p -r

That Terminal command returns a blank?

here's one more photo. auto brightness off, 100%, TT on. I don't think TT is a good test personally since it changes with ambient lighting but I did it anyways, and looked at trailers with it on anyways - don't see any red.

I think it may be one of those things where just a tinge more tint will make it show, and mine 'barely' doesn't show it? It still looks different to me than some photos I've seen, including yours, where there is a bit of magenta at the edges bleeding through. Mine just looks like diffused and scattered rather than sharply brighter red in the top right, etc. and 'clouded up' as I see in other photos in specific areas

I swear I'm picky as heck with screens too, and I don't see red in these conditions.

I see some photos that look a bit more extreme - whether its the camera, the panel, both, I dunno since I don't have them in front of me.

But I think mine is free of this fault as best as I can tell in different situations

Did not seem to work here either, damn. I got it install xcode I think but still nothing. How to check Xcode working by the way? There must be terminal command to read edid and tell the panel maker.

I don't know what causes what you say but the photos show the pattern, so not sure.
I guess we have to wait and see someone with red glow goes hunting for a serial FV like yours.
I hope it does not end up being a fools errand to try... :)
Anyone else care to chime in and comment?
