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.

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.

Development isn't hard on ram. Doing what Apple claims this device is designed for, spending lots of time in multiple browser tabs, is.

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.

I used to be able to get by with just 8GB on a mac. But these days I have to run entire clusters locally

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

Unless you do something unusual like open a web browser. The number of times I “fix” my wife’s computer by just closing some pages…
