I recently erased my M1 Air 8gb Mac on Tahoe and use it for basic stuff like browsing music podcasts video conferencing etc. while I moved work development to linux. Runs really great for it. Now add things like Xcode/Vscodium, iTerm, preview, slack and you are going to see it become hot and in general slow down. CPU usage easily goes beyond 50% now.
When I got the Mac a few weeks after launch, I was doing these exact same things daily. In fact I used Xcode and Emulator back in 2021 frequently along with many apps. It had no slowdowns. Maybe things would occasionally stutter if swap/cache was used and I did too many things. I also relied on rosetta 2 apps at times so things were not exactly optimised either. The overall experience was 'Apple Silicon is FAST'
If anyone with Monterey can test their M1 Air 8gb with Tahoe they will definitely notice a difference in doing the same tasks.
I am not arguing the M1 Air is slow. I am arguing that the Macs now run slower for the same things than they used to with the prominent change being macOS. The headroom for apple silicon was really high. How apple managed to use it up is something that feels very shady given that macOS doesn't do much more than it did 5 years ago that would warrants the usage.
note: disabling Apple Intelligence doesn't make much of a difference.
I agree. 8GB is enough for simple development tasks. You’ll start to suffer if you have too many documents open in Chrome or start running middleware and other services on your laptop. For that I recommend at least 16GB and, in the case of Apple’s inexpandable memory, ideally more. Remember the laptop will keep working for a decade.
Can't imagine what one needs more than 16GB for unless it's local LLMs. I regularly do front end dev while I'm editing 10-bit 4K60 footage in Da Vinci Resolve, runs smooth as butter.
Tons of programming tasks requires at least 32gb to be somewhat comfortable, think of having running databases, running tests in background, running simultaneously multiple docker images, virtual machines, have one or more code projects open in an IDE with LSP (whole code database needs to be in cache), one browser with 20 tabs, and maybe one or more heavy electron apps (Teams/Spotify). You really quickly reach 32gb when doing real development.
My work 64GB M1 Max Macbook Pro is consistently out of memory. (To be fair my $LARGE_ENTERPRISE_EMPLOYER reserves about half of it to very bad Big Brother daemons and applications I have no control over)
I have a 128GB M3 Max from my employer. Due to some IT oversight, I was able to use it for a few months without the corporate "security" crapware. Didn't even ever noticed this machine had a fan before the "security theatre" corporate rootkits were installed.
While I agree with you, I think it's important to note that MacOS does swap to disk quite often, even on 16 GB. While it's rarely noticeable due to how fast the internal SSDs are, it still leads to some degree of SSD wear (and disk i/o usage) that could be avoided with additional RAM. I can't imagine this leading to drive failure considering how long the lifespans of SSDs are though.
Pretending your laptop is a screaming fast workstation and compiling C++ code on all cores can use quite a bit of RAM.
(I have a MacBook Pro that is only around 10% slower at this than an AMD workstation. The workstation has considerably higher TDP. I’m quite impressed.)
For mobile app development, running all my local docker containers for backend services, plus 2-3 iOS/iPad simulators and 1-2 Android emulators quickly pushes the memory limits.
I have an M2 Macbook Air with 8GB and it struggles even without the light development part, and latest macOS made it all much worse. To be honest I am impressed how fast the experience degraded as there was a lot of headroom.
I've been using 8 GB on my M3 for years as a security engineer, doing pretty heavy development. I usually have like 15 Brave tabs open, several terminals, a game (PokeMMO) and a small DeepSeek model, lots of Claude Code instances running, Obsidian, and LadyBird, among other small things. I honestly have no idea what people do with all that RAM.
To provide my anecdata, my work MBP is 48GB and with nothing more than our dev environment, VSCode, Slack and Chrome it's at 34GB memory used. Modern NVMe drives make swapping to disk bearable (and it's the same on MacOS and Linux), but it is still swap and there will always be a performance penalty.
Sure I could survive with a 32GB machine but over the many years of life a laptop has, the extra cost seems negligible, and I would prefer to have slightly more RAM than I need rather than slightly less. With how bloated the web is becoming I wouldn't recommend an 8GB machine in 2026 to someone who intends to use it for the next decade. (I know people still using 2013 Macbooks with 16GB that are still fine for the kind of usage the Neo is aimed at.)
Oh yeah well I run 500 VMs of Windows Vista each with an instance of DeepSeek botting Neopets stocks for me. I make more neopoints in a day than you'll make in USD in a year.
/s but I suppose I've developed a work flow that adapts to the RAM I've always had. I've seen people with zillions of tabs and I do wonder if it's really that much more productive than the occasional HTTP request to reopen one. I find leaving things open as a form of bookmarking clouds my mental space too much.
I do intend to have beastly RAM on my new desktop so who knows, maybe I'll be like you in a year.
Yes, I had a base 2015 MBP with 8GB RAM until recently. It was fine for light local dev: Node or Python backends + Postgres + a small Linux VM. And personal stuff like email/browsing.
Wasn't ok for heavy IDEs like Android Studio, but I barely used those. My actual use case was light.
lmao the koolaid in this thread is mind boggling. most of the development on mac unless everybody is doing iOS and Swift development with 3rd party web services / APIs, is going to involve brew/virtualization. currently running 29GB out of 32GB on M4 for work. This is just absolute unrealistic claim.
I also survey and manage development env for a 250 engineer tech org. 8GB is not going to fly
Are you saying you and all your devs are doing light development work? That was the claim you're attempting to refute.
Light development for me is some node programs and a php server. If light development suddenly means 3 docker containers our world sucks IMO. People shouldn't need multiple operating systems to develop, that feels crazy wasteful.
But is the system choking? Or, are you certain it would choke with half the RAM you have? It's a well know thing that OS will book majority of the RAM you have and that's actually not a problem at all.
