[@srideepprasad]

This issue is the result of a bug/oversight from Apple and not just due to unoptimised apps as you mention (even with the overhead of Rosetta) Firefox and Chrome are not optimised even on x86, but I don’t see such kind of crazy swapping even on very constrained Windows /Linux systems with 8GB of RAM or less…I also often boot up multiple VMs on my 16GB RAM equipped laptop, but never hit this level of swap

[@adr3510]

Maybe it’s on purpose to make people buy more macs

[@HansOvervoorde]

The honesty of this video pleases me. Your advice is very important to keep M1's with 8 Gb of RAM running for many years after warranty is over. I was appalled by popular videos stating that MacOS on M1 is so memory efficient that 8Gb of RAM is enough for most tasks. Which I found strange since the RISC (M1) instruction set needs more RAM than CISC (x86) and pictures and music libraries take up the same amount of RAM on M1 as on Intel. But not mentioned is that that 'memory efficiency' is mainly by heavily applying the decades old solution of swapping contents from too small RAM to storage, the SSD. The basic M1/8Gb/256Gb Air and Pro are definitely very fast and reasonably priced, although lacking 4K displays. But I am afraid that many people will be disappointed with these particular models if not aware of your advice while using it heavily. I find it sad for used and refurb buyers and for the environment that a dead SSD renders the whole computer to scrap, knowing that the SSD and RAM cannot be replaced or expanded for commercial reasons only. Definitely not for technical reasons.

[@james11h]

After obsessing over these numbers for a week myself (often seeing 8+ GB swap while running my VMs), I figured it wasn’t worth the mental energy and I returned it. I’ve got a 16GB MBP on order. It’ll take 2-3 weeks to deliver but it’s worth the wait and extra cost if I don’t have to worry about it anymore for the next 5+ years before I buy another laptop

[@adr3510]

I just bought an 512ssd 8gb MacBook Pro 13”. Is this a bad decision, should I really just stretch my budget the bit I need to go to be able to get a 16gb ram?

[@AttilaTheDev]

I can confirm this. I ended up with the same conclusion. Being a software developer it dawned on me that unoptimized apps and Rosetta 2 more than likely hammer the hardware more than the rest of the apps. As soon as I started using less of those, the machine started feeling a lot snappier, and also swap usage has decreased by a lot.

After 2 days of getting the M1 air, my kernel_task was 63GB, As a first time mac user. This was kinda scary so I rebooted my Mac. I realized that rebooting stops kernel_task (but till then this swap issue wasn’t out and nobody knew about this swap issue), and then for 3 months, I shut-down my laptop every other day. After 3 months I came to knew about this swap issue thingy. After so much of god damn insane usage editing video for my channel, writing blogs, USING SQUARESPACE on chrome for hours (which takes like 3gb ram, Just Squarespace.) I thought my swap data would be around 300TB+, Yes. I use my laptop like a monkey. After I checked that My overall ssd health is 99% with only 2TB data written. That’s 298TB less than what I thought. Hence: for me, rebooting everyday or once 2 days or once a week reduces swap memory data written. This is a temporary fix for now

[@techtamilan3700]

Is that bad 99% ?

[@CreatedTech]

Rebooting only ends the kernel task and resets that value in Activity Monitor, it will still write to the SSD normally when you reboot. I'm curious, what RAM and SSD size do you have?

[@iDeviceSlash]

@@CreatedTech I have 256GB M1 AIR. Imagine kernel_task is 100GB, as soon as you reboot your Mac, kernel_task resets to 0. And then it starts again from 0 If you didn’t rebooted your Mac that night, It will rewrite that 100GB from the old session + continue writing from the current session. So technically, If you don’t reboot: 100GB (rewritten) + data of current session If you reboot: 0 (written) + data, only the data of current session. It’s just what I think; and I only use native Mac apps like Xcode, safari, Final Cut Pro, Logic Pro, motion

No

[@Windschutzscheibe]

Indirectly yes, since if you are not using the internal ssd for storing large files, like movies, high quality videos, then it will have more life left in it, and you will get away even with a significant amount of swap memory usage. And to be fair, most people wouldn't have to worry about swap usage at all, since the ssd will probably last you 5-6 years at bare minimum WITH swap usage, and by that time you will have bought a new MacBook or other laptop anyways. These things are meant to be used, and like everything else that's used, gets amortized. But I assure you that the lifespan of the ssd is the last thing you should worry about in the long run in these laptops.

[@Piketom1]

I posted in another forum noting the difference between my 2020 Intel iMac and my M1 MacBook Air. Even when using all 32GB of system memory in the desktop to run virtual machines and compress recorded videos, it does not swap any memory to the SSD. The MBA, by contrast swaps about .5 - 1.5GB of data to the SSD while I am only using 6 of the 8GB of available system memory. Someone noted that the iMac is not conserving system memory while the MBA is because the iMac does not need to. This really reiterates the point that while the M1 Macs are very impressive and very capable, they cannot truly replace a high end machine for high end workflows. For that, we do need to wait for the M1X versions.

Good question...I had that question too

[@MarkoEsp]

Getting the 16gb would most likely solve the problem and is the right way to do go. Swap memory is used when theres not enough RAM. In the old days this wouldve looked like an insanely sluggish system, beach balls everywhere. Instead of putting more memory into their stock systems Apple put good, fast SSDs so when it uses swap it doesnt slow down, but it kills the SSD faster instead.

[@ANAS577]

I think a combination of Both because even if you get the 16 Ram, programs will use more Ram because it's available for them, i mean doing some basic work on 16gb ram laptop you might use 8 to 12. when it comes to 8gb ram, also doing basic work you will use from 5 to 7.

[@96Steeve]

Another alternative is to simply disable swap. Granted, you won't be able to multitask as well and your device will suffer more if you're editing, especially on an 8gb machine, but it is the only option that will not damage your SSD at all.

I think the takeaway is that while it's perfectly possible to run three different browsers, each with plenty of tabs, and a load of other apps (both Apple and Intel), it's not necessarily advisable with the base model. In terms of swap, I find Edge seems quite efficient. If you're in the Microsoft Space, you can save resources by running things like Teams and Skype (both otherwise Intel based at the moment) from inside Edge. Right now, I'm running Word, OneNote, Tw@tter, Safari and Edge (both with exactly the tabs I need). 81.5MB of swap space and 1.68GB of cached files (so not too bad).

I received my M1 Mac Air on Friday afternoon, just after watching this video. It updated to 11.2.3 and time since boot is 2.5 day’s. Installed a bunch of iOS apps, MS Office (skipped OneDrive as it requires Rosetta), Affinity Photo, Little Snitch, Final Cut, Logic Pro and so on. I’m using only Safari. Swap usage is non existent, kernel task at only 4.12 GB until the test below. I hadn’t watched any KZbin content, spent quite a few hours in Mail, Affinity Photo and Safari and quickly checking out how other apps perform. I see the pressure test in your latest video is KZbin, so tested it just now in Safari and kernal task is going up by about 1.5GB per hour with a 1080p 60 music video constantly playing. So no problems :)

[@CreatedTech]

Don't feel like you can't use Rosetta or limit your use of third-party non-optimized apps. It's perfectly fine. I personally use my MacBook normally without any precautions even on apps such as Photoshop or Chrome. If you are however seeing excessive data being written there are steps you can take, but in my experience 99% of users don't have these issues. It's why I ask people to simply monitor their usage from time to time, just to double check.

[@Sixth6Sense]

@@CreatedTech yeah, I'll still avoid it. As it is it's super efficient, the Air is tremendous value.

[@JDCarnin]

I think Apple fixed it. I'm doing light work and some Photo Editing and in the Activities, the Swap Usage is 0. Got my M1 Mac a few Days ago an heard about this Issue and checked. In the last couple of Days, the total Swap was 390mb on my Machine. Got the Base Model M1 Macbook Air.

[@maxgonzalez5618]

Greta video!!!! I just have one cuestión, according to The Web, Microsoft realesed a versión of office already optimized for m1 ( on december).. is that correct? Or is just they optimized it to use it with Rosetta? Thanks for all this great content!!!

[@Otis2277]

DO NOT WORRY. The number is just a counter. It's not a NAND P/E counter(TLC is up to 1000 cycles per cell). It's not a NAND written bytes. 256GB SSD's TBW is between 200TB(Micron MX500) to 300TB(Samsung 970 EVO plus)

[@johnmknox]

It is not worth buying an Apple product especially with lower memory and SSD capacity until the applications you use are available natively because even after your changes it is still writing a heck of a lot to the SSD. Based on my loose maths It may be three to five times less than previously but it is still likely doing a full drive of TBW every two and a half days and you are now reduced to not being able to use a lot of things that are not natively supported yet on the M1. Before your changes, it was doing up to two write cycles a day for the whole drive that would have wrecked a 256GB SSD very quickly likely in only a few years for many.

[@dy7296]

If the arm mac lineup offers slotted/replaceable ram and ssd, I will buy them no doubt. For some people who believed that ARM chips really require different ram type and different storage type... It's a myth. As an example, a low-end chromebook has a phone-like lpddr4, and phone-like eMMc storage, and it has an x86 processor. And vice versa, an ARM server exists with full size ddr4 ECC slots on its side. And surely Tons of SSDs connected through a full-size PCIe.

[@LJG999ab]

I think this video is helpful. I believe the problem is real and at this point, without clarification from Apple- I would never recommend M1 machines for corporate use. Perhaps corporate groups wouldn't use these machines anyway given that memory and SSD storage is soldered on. As a personal user, with more careful selection of apps and lighter usage- I can mitigate the issue. But I am not happy that I need to do this or need to worry about a given app causing issues- particularly when these apps are widely used. Hopefully Apple will address the issue directly and make OS changes to reduce the level of disk swapping/data units written.

[@DJSelphi]

Gonna wait for M1X and when more apps are optimized for this chip

[@GazuntaiWorld]

Superb review and info, so I have subscribed

[@mixni]

Firefox already has an M1 optimized version, but I've been using that sparingly as video battery life is not anywhere near as good as safari. I mainly use safari as my default when not plugged in, ram usage seems similar. I've been using my m1 air (8gb) for about a week and a half and I've only written about 750GB to the SSD which seemed like a lot since I've been a fairly light user? But I did use discord heavily (rosetta) and I think that's been the culprit for most of that data, as using the web version + daily use I'm only writing about 20-30GB a day. Another tip, if you use "nativefier" (google m1 nativefier) you can create a 'web' ARM version of Discord, but as an app outside of the browser. I've been using that and there seems to be no issue leaving it open, and it doesn't impact battery life as much (while still refreshing for notifications unlike the browser-app).

[@tokumeig654]

It appears the swap used was 0 bytes until after sleep/wake cycle, suddenly it's increased 600MB each time. By the end of the day, 4GB of Swap was used with KernelTask process written 200GB for the day! Something is amiss in the sleep/wake cycle.

[@mahlilapache5741]

I use the latest version of the Chrome on an m1 macbook air and this problem seems to have been resolved.

[@martinsauer4854]

Still MacOS seems to have very poor memory management. Normally a PC shouldn’t use any swap when there is enough free RAM space. Because RAM is way faster. There is no benefit in copying data to swap partition on ssd other than when the PC needs the RAM space for something else and there is not enough free RAM left over. Every Linux OS has a 2GB swap partition where the OS can swap to by default. And I have never seen my Linux PC use this 2GB for swap because it has more than enough RAM and doesn’t need to use swap. 8:50 You can see that there are still so many tasks running in the background most eating 10-50 mb each which adds up to several GB. Additionally Apples new unified memory architecture gets rid of dedicated RAM only for GPU and other things. Now the CPU, GPU, neural engine, T2 chip and whatever all use this RAM. Simply put: Macs with 8 GB RAM dont have enough RAM for intermediate tasks unless they use swap. Never thought I’d say this but MacOS seems to be more bloated than Windows nowadays. The average 500GB NVMe SSD has an average life span of 180TB tbw. Assume the Mac swaps 200GB every day (average from this Videos before and after): 180.000 / 200 = 900 So a 500gb SSD in one of those MacBooks is essentially dead in about 2.5 years just from swap in theory. Great job

[@josechomali]

I commented the same Rosetta 2 swap memory theory in you two weeks ago video “is there a big problem…”; seems we are right. That why I’ve been using discord on my iPad!

[@molfar9049]

it’s been six months, has the issue been fixed by Apple?

[@cricketfreak2010]

You are amazing mate! Appreciate your hard work!! Thank you very much.

[@pashersil]

Safari (Monterey 12.1) and Chrome are both the worst offenders (M1 optimized) .. exactly the same. My guess is that internal caching of web sites using the new grouped tabs features is one of the worst culprits for me. Its related to the tabbing and caching - facility to reopen tab groups mean that in the background these things are kept "live"

[@Visualization1]

You should also take a look at Apple M1 SSD Survey Results - Part 1 from Constant Geekery on KZbin. And then especially the 7:16​ Video buffering to SSD part. There you can see that even the most up-to-date version of chrome writes a lot of data to the SSD compared to Safari while streaming video (KZbin). I always advice Mac users (especially MacBook users) to user safari for the following reasons. Better battery life Better for your privacy Syncs better with your other apple devices Support Apple Pay Has a good reader mode Handoff to other apple devices

[@JGRGilbert]

The problem will be Intel apps that use JavaScript. Firefox obviously uses JavaScript, and I believe Discord is an Electron app. Intel apps are usually cross compiled by Rosetta 2 once when they're first started. Javascript is dynamically compiled, so each time Firefox uses its JIT compiler to produce Intel instructions (when you load a new web page), Rosetta 2 has to then cross compile that to Apple Silicon. I don't think apps such as Adobe apps should have the same problem, since I'd expect them to be entirely statically compiled. I don't, however, understand why this continual cross-compilation hits the swap & SSD. Maybe that is a thing that Apple can fix.

[@tablatom]

great video. I use Logic pro daily. Would it be a good idea to wait and buy a M1 mac with 32gb of ram and a 1tb or 2tb ssd? Looks like more ram helps with lowering memory swap.

[@ejitp6cl6]

At least photoshop and word both got native apple silicon support now. Hope lightroom classic will follow up.

[@priultimus]

4:50 Interesting, I'm using an 8GB M1 Mac Mini and as it stands, kernel_task has written 7.44 TB over the course of 23 days, of which I've used this mac with medium to heavy usage almost everyday (at least 20 tabs open, Discord, sometimes Safari, Notion, Spotify, 2-3 youtube videos being watched, sometimes taking facetime calls, occasional use of visual studio code, xcode). I wonder what's changed.

[@priultimus]

Oh I misunderstood. We've used roughly the same amount. Makes sense.

[@antfirmin]

MacOS 12.4 - still an issue? Over 45 days, the kernel task on my M1 MacMini with a 1TB SSD and 16GB of memory has written 33.83TB of data according to the activity monitor. I think this is still an issue and not something that is going to go away any time soon.

[@JanineMKartist]

The whole point for those of us who use/buy MacBook Pro is precisely for graphics/art applications . To not use those apps is to basically quit being a graphic artist. Totally makes no sense. That being said I won’t add Firefox or chrome on my new m1pro Mac,. I’ll continue to use my old mbp when I need to access chrome or Firefox . Let’s hope those new machines just released will have less of an issue. Good tip on not leaving applications open when not using . I also build my website on a browser based Wordpress builder called Divi so I hope it doesn’t suck my computer dry . Hopefully using safari will prevent that .

This is probably pretty heavily reduced on the 16GB models because less swapping is required. ARM apps use less ram.

[@adrian1622]

No, it s not. That s the apple ''scam''. If an MacBook has 8 gb ram it will use 8 gb ram plus 2-3 gb swap. If it has 16 gb ram it will use 16 gb ram+ 2--3 gb swap.

Lightroom is native now, it is also on the apple App Store, photoshop is also M1 native now but the dumb thing is that adobe cc desktop app is still x86 and photoshop isn’t on the App Store. And adobe cc desktop app had background tasks running through Rosetta 2. For discord, just use the browser version.

Just Lightroom not Lightroom Classic

[@MarkPayneAudio]

Nice work sir. Here is a premise... Rosetta apps are not bad for memory management by definition. Bad Rosetta apps are bad.

[@swipekonnect]

the solution: apple provides a dedicated swap drive as a user replaceable m2 on the base, shut off machine to remove magnetic locking, then unscrew the cover and change the drive. apple can force the drive being used for only swap via os level rules

[@rubenthedoornob6949]

or just ya know a normal replaceable m.2 (for general storage) so that when it or by change your entire machine dies you can actually get your data of it. but thats just me

[@swipekonnect]

@@rubenthedoornob6949 i thought about that, allowing main drives to be replaced invites all sorts of warranty issues not so with scratch drives (not to mention it does not disturb their lucrative storage upgrades)

Will the decreased usage of swap in the latest version MacOS have an performance impact which makes previous M1 Mac speedtests and reviews unreliable?

[@joesosa41]

It just matters if those tests and benchmarks and work flows were "m1 optimized" or not.

Apple created rosetta 2, they were the ones that messed up and made it use a lot of swap memory. The x86 apps weren't using that much swap memory before.

TB per two days? This is absolutely ridiculous. They need to fix swappiness. My Arch Linux with KDE Plasma Desktop wrote 0 Bytes to swap in the last two years, I have around >2000 Chromium tabs (no joke) opened while the entire time, and many other tools like Integrated Development Environments.

Keep in mind, Chrome is not swapping, it is downloading. If you watch lots of KZbin, this is what it is supposed to do.

[@ckpriv6167]

Hi. nice job! When you compare usage you should start fresh on cache and compare using the same os version. It is hard to know if it is native app, cache or mac os update that improve the write there. I check on my own mac, I use chrome often, terminal, and big matrix room in chrome. I have got several apps running all the time like nextcloud... My uptime is 14.5 days. My kernel tasks wrote 13.48 GB ! which is far less than I can see on you video. For me I’m pretty sure that having 16GB instead of 8GB has a huge impact.

[@aldog1107]

I was only really worried because I had my MacBook for 2 months now and it never used ANY swap data. (My usual bites written was around 1GB per day even with apps like discord open.) It was just recently that I got parallels desktop for my Mac and all of a sudden it jumped to 200GB per day.

I've owned my M1 MBA for about 3 weeks now and after watching this video I decided to check my 'Kernal_task'. I restarted my M1 MBA about a week ago after updating to 11.2.3 and since then it has just written over 1 GB. I'm not a pro user, I don't use Windows suite of Apps or Adobes, I don't use Firefox or Chrome and I don't have Rosetta 2 installed on my machine, which I suspect might have something to do with the high writes.

[@etmindr4328]

another idea: the speed of the internal ssd is high at round about 2800 read and 2200 write. so faster than the most external ubs3.2-drives. my idea to higher the livespan is: using an external drive with up to 2800 readspeed and use a part (a small partition) of the internal ssd for the swapper. so you have the chance to use a part the internal ssd a serveral times until it breaks ... what do you think ?
