As a proud user of an ARM3 in 1992, I'm pleased to be able to see and say that ARM won in the end.

ARMv8 is not much like previous ARMs. But it has won - Intel's latest x86 extension basically turns it into ARMv8.

Memory doesn't need to be freed until a different software needs it.

I'm referring to what Activity Monitor app tells me in its memory tab - not the underlying malloc/whatever implementation being used. It tells me my computer is using 8gb of RAM after a restart and I haven't begun to open or close anything. Yikes?

It's very hard to measure memory use because it's reactive to how much RAM you have; if you have more then it's going to use it. That doesn't necessarily mean there are any issues.

Question to more senior Mac users: how do you usually decide when to upgrade? I bought my first Macbook pro about a year and a half ago and it's still working great.

People have different passions, I like computers. If I feel a new Mac is going to be fun for whatever reason, I consider upgrading it. Performance wise they last a long time, so I could keep them way longer than I do, but I enjoy newer and more capable models. You can always find someone to buy the older model. Macs have a great second hand market.

I was quite surprised by this discrepancy as well (my new iPhone has 7, but the new MBP does not). I had just assumed that for sure this would be the year I upgrade my M1 Max MBP to an M4 Max. I will not be doing so knowing that it lacks WiFi 7; as one of the child comments notes, I count on getting a solid 3 years out of my machine, so future-proofing carries some value (and I already have WiFi7 access points), and…

they hold their value well so you could buy it this year and sell it next year when you buy the new one. you'd probably only lose ~$500

Good point! I hadn’t looked at how resale value holds up. Maybe I will do that after all… thanks for the suggestion!

The single core performance looks really fast. Chip | Geekbench Score (Process) ---- | ------------------------ M1 | 2,419 (5nm) M2 | 2,658 (5nm) M3 | 3,076 (3nm) M4* | 3,810 (3nm) In my experience, single-core CPU is the best all-around indicator of how "fast" a machine feels. I feel like Apple kind of buried this in their press release. M4 benchmark source: https://browser.geekbench.com/v6/cpu/8171874

Conversely, the M3 supposedly has better multi core performance? How is that possible?

It doesn't.

> I've never kept any laptop as long as I've kept the M1. My 2015 MBP would like to have a word. It’s the only laptop purchase I’ve made. I still use it to this day, though not as regularly. I will likely get a new MBP one of these days.

You'll be glad you did. I loved my 2015 MBP. I even drove 3 hours to the nearest Best Buy to snag one. That display was glorious. A fantastic machine. I eventually gave it to my sister, who continued using it until a few years ago. The battery was gone, but it still worked great. When you upgrade, prepare to be astonished. The performance improvement is difficult to convey. It's akin to traveling by horse and buggy.…

> The battery was gone, but it still worked great.

A family 2018 Macbook Air got a second life with a battery replacement. Cheap kit from Amazon, screwdrivers included, extremely easy to do. Still in use, no problems.

> "up to 1.8x faster when compared to the 16-inch MacBook Pro with M1 Pro" I insist my 2020 Macbook M1 was the best purchase I ever made

Except for the usb c charge port - magcharge was the best invention and I’ll never understand why it was removed.

Pro tip, USB c magnetic adapter is cheap and works well enough

Activity Monitor counts everything from I/O buffer caches to frame buffers in the "memory used" metric. Add in that MacOS won't free pages until it hits a certain memory pressure and you get a high usage with no desktop apps open.

This also means that cleanly booted machine with 16 GB will show more memory used than a machine with 8 GB.

Apple suggests you use the memory pressure graph instead to determine whether you're low on memory for this reason.

Privacy is the new obscenity. What does privacy even mean to you concretely? Answer the question with no additional drama, and I guarantee you either Apple doesn’t deliver what you are asking for, or you are using services from another company, like Google, in a way that the actions speak that you don’t really care about what you are asking for.

There's some weird[1] laws around privacy in Australia, where government departments are blocked from a bunch of things by law. From my perspective as a citizen, this just results in annoyance such as having to fill out forms over and over to give the government data that they already have. I heard a good definition from my dad: "Privacy for me is pedestrians walking past my window not seeing me step out of the showe…
