Hey guys, I just thought I'd post a semi-detailed long term review of the M1 macbook air from a software developer perspective, in case it might help others make a purchase decision. I have 2 m1 macbook airs, one is a 256gb ssd 8gb unified memory version and the other is a 512gb ssd 16gb unified memory version. Both have the 7core gpu, since I have no use for gpu cores in my use cases. I bought these fairly close to the release date, I think a couple weeks after. I've been using these laptops daily for well over a year now. These are my first apple laptops by the way. I've primarily used only windows and linux OSes in the past although I have used various other apple products like ipad and iphones.

TLDR: Good laptop with a very efficient chip but with major deal-breaking external display issues. Possibly avoid purchase. My personal summary for these laptops is that, while they are good laptops, the external display issues are complete deal breakers for my current setup. If I had known about these issues before my purchases, I would definitely not buy. Additionally, I would not buy the 8gb unified memory version for software development use cases. Also, for those that might be asking why not the macbook pro, well I bought the airs very close to the initial release, so the airs were the only choice back then.

My use case
I am a full stack developer and my main use case comprises of using mainly these programs - VScode, iTerm, Fork (git client), nodejs, npm and pnpm, docker desktop for mac, slack, microsoft teams, postman and a lot of browser tabs. I do have rosetta 2 installed but surprisingly mostly everything now has native arm builds.

My setup
I use both the airs in closed lid clamshell mode most of the time (90%+), connected to external display. I originally had them connected to my main ultrawide, an LG 38gl950b (this is a very high end gaming monitor that I also use with my windows gaming desktop) but due to the major problems I've had with the m1 macbooks on this display (more on this later), I am now using a Benq EW3270u which is a 32" 4k monitor that I had bought a while ago for my playstation. It has a usb-c connection that does dsiplay as well as charge the macbook. Thing to note is that the macbooks still have display issues even with the Benq but to a much lesser extent.

Pros
  1. Fast chip - No surprises here. The arm chips are pretty snappy. Before this, I used to use my main PC which is an i9 9900k based desktop and in most normal use cases the m1 airs seem to be cruising along no issues and I cannot notice any major differences compared to my experience on the i9 9900k desktop. I use javascript/typescript and esbuild along with dotnet core for the most part. Your mileage may vary if you use other more heavy compilers.
  2. Efficient - While the desktop chip obviously has higher raw performance, the m1 arm chips definitely do not hold you back and impressively at a fraction of the power. While the efficiency is unmatched currently by any other chips, I must point out that there are other mobile chips that will beat out the m1s (even the pro and max) for code compile performance pretty handily, especially the new alder lake chips. Obviously at a much higher power draw but whether that additional power draw is an issue or not is for you to decide. For my personal use case, our incremental dev builds using esbuild are fast enough already that a higher power CPU would not make a great deal of a difference in terms of local developer experience and our proper full builds with testing etc. are done on a cloud based CI system anyway so a quiet no fan macbook m1 air is a pretty good device for this type of use case.
  3. Build quality - As mentioned, these are my first apple laptops and I find that the build quality is extremely high. I don't think these are the best looking laptops, subjective I know but I feel something like an almost no bezel dell xps or even the lenovo carbon x1 designs look better but there is no denying that the apple build quality lives up to the hype.
  4. Display - The built in display I feel is great, no complains here. Bezels are a bit large but as noted in my use case, I have the laptops closed 90%+ of the time anyway so this is not an area where I can comment further.

Considerations
  1. RAM (unified memory) - This is not a knock on the m1 air which is why I am putting this under the 'Considerations' category. When I originally bought my first m1, I bought the 8gb version mainly based on the initial reviews that were saying the new unified memory architecture made it so that the 8gb version did a lot more than other traditional memory based devices could. Sadly, this is not strictly true. While, I do think that the 8gb version does go pretty far, there is still a point where you will start struggling. Again, I am not holding this against the m1, just noting it here to say that you should buy more RAM if you feel your use case will require it. And for programming, I can safely say that you will. For me, with multiple VScode windows open, lots of browser tabs (I've tried both the native Safari and chrome/edge), a few terminal windows, the 8gb version can quickly get to a point where its just downright unusable. Sluggish, the rainbow mouse wheel etc. Just not usable essentially. The 16gb version is fine, so far I've never seen it become sluggish under heavy use even with tons of programs and browser tabs running. So, if your use case demands it, go for the 16gb version.
  2. Battery - As mentioned, both my airs are plugged in and lid closed pretty much 24x7. One of them that gets a lot more use than the other now has its battery condition showing as 92% while the other relatively lesser used is still at 100%. As, I've not had an apple laptop before these, I don't know how this compares but I feel there is no issue here.

The Problem

This is where the entire experience just goes south for me atleast (many others also have documented the same issues). The m1 chips seem to have some very serious issues with many external displays (from various manufacturers and various different models). The issues vary from major flickering, vertical lines/bands on the screen, serious ghosting, display signal limited to YPBPR instead of full RGB and temporary image retention/burn-in issues etc. There are various forum posts all over the internet, even detailed threads here like


Unfortunately for me, I've experienced pretty much all of these issues with my main monitor the LG 38GL950B. Major flickering, vertical lines, image retention, no RGB signal, the whole 9 yards. I've been using this monitor for nearly 2 years (and still do) with my i9 9900k/rtx gpu windows gaming PC running flawlessly with full RGB signal with no issues but as soon as I bring the m1 into the equation, its just a dealbreaker. I've tried numerous things like using the caldigit TS3 dock to connect to the monitor, use various expensive 4k/8k hdmi cables, various fixes and workaround, various display setting combinations, initially even sent back the macbook m1 (in its 30 day period) and bought a new one with the exact same issue. The issue has been present from day 1 and still is even with the lastest macos version which seems to suggest to me that this is a hardware level issue. Apple obviously is completely silent on the issue. Maybe it does not affect a large enough % of users to make it worthwhile for them to fix.

I've since switched to using the m1 macbooks with a Benq EW3270u. This monitor fairs a bit better than my LG. There still are some minor temporary vertical lines and some temporary flickering but for the most part the experience is issue free, lets say 95% of the time which makes it useable.

I don't know what the exact issue is and it is possible that these monitors are also not completely blameless. Maybe they are doing something incorrectly which along with the m1s issues combine to cause these problems, no idea. But the fact is that I've been using both these monitors well before I bought the m1s and have had 0 issues using these with my windows machine or my playstations. The only machine that results in issues on both these monitors is both the m1 macbooks and other users experiencing this issue also have the m1 chip as the only common thread.

Bottomline: These laptops are overall great and if you know that you have a known good external monitor to use with these, then I can recommend it as a good laptop to buy. However, if you are not sure that you have a known good monitor to use, then its quite possible that it will become a monitor lottery issue. For me personally, the experience has been less than ideal and crucially, I feel that Apple's complete silence is a bit of a bummer. In any case, I will be waiting a bit longer to see if these issues are fixed with the m2 chips. If they are not, I will be selling my m1 airs to buy a non apple device. However, if these issues do get properly resolved with the m2 chips, then it is quite likely that I will purchase the m2 based chips.

Let me know if you have any questions and I will try my best to answer.

Thank you for your excellent post.

I have seen tons of reports and complaints about the M1 Mac Mini too. :(

Video from a guy who bought the M1 Mac Mini. He spent days unable to use his new computer because of trouble working with his Apple monitor. The monitor worked fine on his other Mac though. After trying everything, including working with his contacts at Apple where he used to work, searching the internet, etc. he found a kludge that got it working. Other people not as lucky. A nightmare. He was about to go buy a new monitor and hope that it would work with no guarantee that it would since there was no way to know why his monitor would ONLY NOT work with the M1 Mac Mini.



I have found lots of stuff about monitor problems with the M1 Mac Mini. This is a long 29 page thread that started in 2020 and the most recent posts are in 2022:

I am surprised to hear about all these display issues. I have tried my M1 Max with a number of Dell, LG and ASUS monitors in out office, as well as with four different projectors — all worked like a charm.
That’s most likely because the display engine in the M1 Pro and M1 Max are much better, supporting more monitors and higher resolution.

I returned my M1 Mac mini because of monitor issues, was otherwise pleased with the performance.

One of the things that is perplexing to me is that several times I have read of a particular monitor having problems with an M1 Mac Mini and then I will read someone saying that the exact same monitor model works fine for them. And that is true for various monitors. The video above I posted is an Apple monitor even. Unfortunately, usually there is no info about when the M1 Mac Mini was purchased in the many posts on the internet. Maybe earlier ones had a problem and then Apple quietly made an engineering change and later ones are okay? Or maybe somewhere along the way there was a MacOS update that quietly fixed things. I doubt both of those things though and without any knowledge about the purchase time of the computers we can't know.

This is the sort of problem where if Apple did make an update to newer versions they should tell people. All the bad blood based on the thousands of posts, videos, etc. on the internet could then be discounted by customers who want to buy. The only reason I can guess why Apple might quietly fix it and not announce it is because they don't want earlier customers to demand the fix too.

I am very hesitant to buy an M1 Mac Mini right now even though I want one. Possibly on March 8th there will be a new one announced. Just rumors right now though. Even if there is, will it have this problem fixed? Apple seems to be very quiet about this. And also about the infamous Bluetooth problems. :(

I bought a second hand Mac mini about a month ago. It was purchased by the original owner in November 2020. I have it hooked up to a Dell U2520D vie HDMI and have had no problems whatsoever.

So, who knows?!?

*Also no Blue tooth problems either...

Yeah, that is why I stayed away from the M1 chip.

I only tested my 16" M1 Max MacBook Pro with a 4K display from Samsung and it worked fine so far. Not sure if I was lucky or that Apple fixed external display support with the M1 Max chip.

Hopefully the M2 chip will fix the bluetooth and display problems of the M1.

I don't remember which thread exactly, but if you read through one of my linked threads in the original post, there was at least one guy who had very similar issues (flickering etc) with his macbook air and then upgraded to a pro and also experienced external display issues, albeit to a much lesser degree. What I can suggest is, if you are interested in buying a mac mini, buy one and try it out within the 14 day return period. One thing Apple are genuinely good at in my experience is honoring the hassle free return. If you experience issues, you can always return it within that period. However the risk is if you encounter issues after the 14 day period. Might be best to wait for the March event and see what's in store.

Well, is the color space YPBPR or RGB?

I only recently acquired a new M1 MacBook Air 16gb / 512gb version and have it connected to a fairly low end 4K Lenovo monitor regularly and have absolutely no issues whatsoever.
My workflow is fairly mundane, mostly MS Office. I did however have an issue getting this monitor to work with my prior intel MacBook Pro. The only way to get it working properly was with a USB-c to DisplayPort cable and I’ve continued to use that same cable with the MBA.
It’s been over 10 years since I’ve done any serious development work so can’t comment on your use cases. I chose the 16gb version simply because I frequently need to access legacy windows software and therefore need to run virtual machines. For me, the M1 air runs flawlessly.

I have an even lower end Lenovo 2K monitor, and it works fine with my M1 Mini. Maybe the secret is buying cheaper monitors? ;)

2k would shred your eyes though, wouldn't it, given how macOS now handles low-res outputs? I went from a 1440p display to 4K and it was a night and day difference.
Granted, it's nothing special, but I find it decent overall. Hoping to upgrade to a 4K monitor this spring, so I'll probably notice the difference then.

I like that you listed FIRST and foremost on considerations is RAM, and I also agree with you.

I know most here are talking about display, but the RAM… with 8GB the memory pressure I see is not satisfactory.

Specifically for the use case of development and Running multiple VMs… I’m only running the most lightweight server installs and I know it need more. 8GB is pushing it. 16GB however would easily be enough for this.

I wish this had been more widely known in the beginning. It’s a whole slog to sell my current one to get a another one with more. The hassle & time… and the wait if the March event will make any difference.

8 GB for a developer, nah. That was not wise
Clamshell - I would not use a computer, especially a passively cooled one in this mode, too much heat will shorten life and throttle performance
I have m1 MBP, so not totally comparable, have had 0 monitor issues. I plug directly with a usbc to hdmi 60hz cable works great. Hdmi through a dock was iffy, cheap dock ram hot and I noticed that you had to use the dock with the usbc power in. No more cheap docks for me
I did check the display profiles, initially I seemed to have a bad one that was quirky, fixed that and no more quirks
Finally get three display support internal, external and airplay

Yeah, 8gb for sure was not enough. I was not expecting it to be even before I bought it, but the reason I did go for the 8gb version first was that I wanted to see if the hype about the unified memory created in the initial reviews had any truth to it and because I was going to buy 2 macbooks anyway (one for personal use and one for work) and I could switch the 8gb version for my personal use which I did.

The clamshell mode is not an issue for me as my workspace is air conditioned and I've never run into any thermal throttling issues with either of my macbooks, although I do see that it can be if you are not in a controlled environment.

Regardless though, as I've outlined in my review, performance for the most part was never an issue for me. The 16gb macbook air has been cruising for me in terms of performance and day to day 'user experience'. If not for the crippling issues with my main LG external monitor, by all accounts these would be very good devices to use and recommend, and as I mentioned in my original post, if you know that you have a known good monitor to use with a m1 device, I can easily recommend the 16gb version.

Who knows? Maybe there's errata in the M1 GPU that QC doesn’t weed out. Some people can use any monitor while others can’t use almost anything.
The problems I've seen were the display color profiles and cheap cables/docks. In my case I had a bad color profile, deleted it and used the right one - fixed. I also tried to use a usb dock to a cheap HDMI cable, that didn't work well. and if I used the dock for anything I had to plug in the power supply. (the dock gets pretty warm, I suspect that is the prob. If I plug my display in using a USBC to HDMI cable no issues at all. My read on these "issues" is that some may be legit, but others are just non-existent trouble shooting and it comes down not to the M1, but the peripherals and cables. Making sure the correct color profile is used is also important

I also tried to use a usb dock to a cheap HDMI cable, that didn't work well. and if I used the dock for anything I had to plug in the power supply. (the dock gets pretty warm, I suspect that is the prob. If I plug my display in using a USBC to HDMI cable no issues at all. My read on these "issues" is that some may be legit, but others are just non-existent trouble shooting and it comes down not to the M1, but the peripherals and cables. Making sure the correct color profile is used is also important

Using the wrong color profile would normally not cause the screen to flicker or actual image retention. At worst, a wrong color profile will result in basically inaccurate/washed out colors etc. For example, see the two attachments posted by this guy of serious image retention in this thread - https://forums.macrumors.com/thread...g-with-external-display.2271670/post-29668060 or the video of flicker posted in this post - https://forums.macrumors.com/thread...g-with-external-display.2271670/post-29719472 . There is no way using a wrong color profile would (or should) do this.

I've also experienced both these issues myself on both my LG and BenQ monitors (the BenQ is impacted to a lesser degree). And these are monitors I've used for years and still do with various other computers and devices like playstation with 0 issues (including an intel based macbook air I borrowed from my sister for testing). Both my m1 macbooks however can reproduce the issues again and again very reliably though. And I've used direct connections with high end hdmi/usb-c cables, high end docks like the caldigit etc. to no avail.

Obviously though, by the looks of it, the majority of buyers of the new m1 chips are largely unaffected by these issues, which is great. However, it is still good to make prospective buyers aware that these are great laptops albeit with a serious caveat of external display issues, depending on which monitor you have or plan to use so they can make an informed decision.

...Battery - As mentioned, both my airs are plugged in and lid closed pretty much 24x7. One of them that gets a lot more use than the other now has its battery condition showing as 92% while the other relatively lesser used is still at 100%. As, I've not had an apple laptop before these, I don't know how this compares but I feel there is no issue here.
A nice, well balanced review. Leaving it plugged in at 100% is bad for the battery over time; consider Aldente which lets you control the max percentage it charges to.

Ah, thanks. This is good to know. I had assumed that macOS already was smart about battery charging (In the battery settings, I can see that there is an 'Optimized battery charging' setting that claims it only charges over 80% when it needs to). I might have wrongly assumed that this was all I needed even if I left the laptops plugged in all the time. Looks like it might not be based on your comment. Will definitely have a look at the app you linked, thanks for the tip.
