Mac OS calls home every time you execute an application. Apple is well on its way to ensure you can only run things they allow via app store, they would probably already be there if it wasn't for the pesky EU. If you send your computer/phone to Apple for repair you may get back different physical hardware. Those things very much highlight that "your" Apple hardware is not yours and that privacy on Apple hardware does…

They send a hash of the binaries/libraries, and generate a cache locally so it's not sent again. That helps stop you from running tampered-with binaries and frameworks. No user-personal data is sent. There is no evidence at all that they are trying to ensure you can only run things from the App Store - I run a whole bunch of non-app-store binaries every single day. To make that claim is baseless and makes me de-rate…

> I run a whole bunch of non-app-store binaries every single day

if you are in the US, you need to either register as a developer, or register an apple id and register your app to run it for a week. that's how you run non-app store code. Both of those require permission from apple.

EDIT: Sorry, ios.

Their repair policy, from what I can see, is a thinly veiled attempt to get you to either pay for Apple Care or to upgrade. I got a quote to repair a colleague's MacBook Pro, less than 2 years old, which has apparent 'water damage' and which they want AUD $2,500 to repair! Of course that makes no sense, so we're buying a new one ...

> to get you to either pay for Apple Care The problem with many self-repair people is they effectively value their time at zero. I value my time realistically, i.e. above zero and above minimum wage. It is therefore a no brainer for me to buy AppleCare every ... single ..time. It means I can just drop it off and let someone else deal with messing around. I also know how much hassle it is. Like many techies, I spent p…

A big problem with Apple Care is here in Thailand anyway you need to give them your computer for a few weeks. You have to wait a week for them to look at it. They won't even allow you to use it and then bring it back in a week.

This is completely incorrect. You can download a random binary and execute it. You will get a warning dialog saying it’s not signed by a known developer. You are free to ignore that though.

> If you send your computer/phone to Apple for repair you may get back different physical hardware. I happen to be in the midst of a repair with Apple right now. And for me, the idea that they might replace my aging phone with a newer unit, is a big plus. As I think it would be for almost everyone. Aside from the occasional sticker, I don't have any custom hardware mods to my phone or laptop, and nor do 99.99% of peo…

It could help to compare to other makers for a minute: if you need to repair your Surface Pro, you can easily remove the SSD from the tray, send your machine and stick it back when it comes repaired (new or not) And most laptops at this point have removable/exchangeable storage. Except for Apple.

The counterpoint is wiping the device and restoring from local backups when it is returned.

Some of it depends on which variant fits you best. But yeah, in general the M1 is still very good--if you hear of someone in your circle selling one for cheap because they're upgrading, nab it. On the variants: An M1 Max is 10 CPU cores with 8 power and 2 efficiency cores. M4 Max is 16 cores, 12 + 4. So each power core is 50% faster, but it also has 50% more of them. Add in twice as many efficiency cores, that are al…

> it's very, very hard to make the fans spin on a 16" M1 Max. You have to utilize all CPU/GPU/NPU cores together to even make them move, I routinely get my M1 fans spinning from compiling big projects. You don’t have to get the GPU involved, but when you do it definitely goes up a notch. I read so much about the M1 Pros being completely silent that I thought something was wrong with mine at first. Nope, it just turns…

Huh! I regularly max CPU for long stretches (game development), but I found I could only get the fans to move if I engaged the neural cores on top of everything else. Something like a 20+ minute video export that's using all available compute for heavy stabilization or something could do it.

The M3 is much more typical behavior, but I guess it's just dumping more watts into the same thermal mass...

> Mac OS calls home every time you execute an application Consulting a certificate revocation list is a standard security feature, not a privacy issue.

Huh? It hashes the binary and phones home doesn’t it? Go compile anything with gcc and watch that it takes one extra second for the first run of that executable. It’s not verifying any certificates

When I first run locally-built software I tend to notice XProtect scanning each binary when it is launched. I know that XProtect matches the executable against a pre-downloaded list of malware signatures rather than sending data to the internet, but I haven't monitored network traffic to be sure it is purely local. You can see the malware signatures it uses at /private/var/protected/xprotect/XProtect.bundle/Contents/Resources/XProtect.yara if you're curious.
