Updates to Full Disk Access in macOS

Can I just tap out of using AI agents altogether, and go back to the "Full Disk Access" setup from Mac OS Snow Leopard, where we just used UNIX permissions?

That'd be my honest preference.

Then you just have malware scraping your home dir for bitcoin wallets and ssh keys anyway.

I can keep the malware off my machine just fine, thankyouverymuch. It's annoying not to be able to set normal permissions on my non-malware-using, non-agent-using machine.

We all like to think that, don't we?

The point of capabilities is protecting against not just malware, but also "innocent" that has been hijacked from upstream. Protection from ""rogue"" AI agents isn't/shouldn't even be the primary goal here, we needed a sandboxed application model 20 years ago.

We're all just one NPM update away from getting our browser cookies yanked.

Or FIDO U2F USB key backed ed25519-sk keys, supported by OpenSSH since 8.2 in 2020, more portable

Nice find!

We are long into an arms race between our private data, and corporations who want us to install trinkets that will attempt to steal everything.

It’s not about AI specifically, they have been pulling this shit for years. AI is just making it worse.

Even if you don’t use AI directly, you can’t trust any app you install, and you can be pretty sure that even without intending to, you’re gonna install software that was written with AI. And who knows what it is going to pull.

Or you could admit to yourself you are not Apple's target customer and draw the conclusion you need to move to Linux/BSD/whatever. I did about a year ago, and it's been much less painful than I expected:

I daily drove Linux on my desktop for several years, and wound up back on mac because I needed to build things for iDevices again. I didn't want two different daily driving systems, and there are actually some things that I like about Mac.

But if I no longer have that need next time I'm ready to cycle hardware, I'm likely to go back to Linux. If we don't have good support for Affinity apps on Linux by then, I'll probably keep an iPad around to run those.

I'm not a professional artist, but I've found DarkTable and Inkscape a perfectly suitable replacement for my previous Mac apps. I hear you on not having multiple daily drivers but that ship sailed a long time ago for me, at last count I have 26 computers, 4 of them daily drivers.

It's impressive how there are absolutely no details in this announcement... I learnt nothing. Seriously though, MacOS could really use a serious sandbox implementation that's actually usable and documented. sandbox-exec is right there and waiting.

I'm guessing they will make FDA an entitlement that will only be granted during App Store review.

Some kind of lightweight containers like I use for build and test on Windows and Linux would be amazing. Instead, just lock it down like an iPhone.

do you mean something different than this? https://github.com/apple/container

That's for running Linux containers not macos containers. I run my Linux containers on my Linux hosts. I want to run macos containers on my macos hosts.

I stopped using Claude Code after it started writing its own programs to search through my whole computer and makes changes as it sees fit to run "experiments". This was a good reminder to actually go back and delete that piece of malware from my computer for good

doctor_eval | 11 hours ago

Yep it will write, build and run code at the slightest provocation, all the guardrails are entirely off.

I alone am responsible for the code I commit but Claude is happy to make whatever change.

It’s out of control and it’s despicable practice.

I found this quote from the MacStories post on the matter interesting:

Looking at this MacBook Pro, only a handful of apps to which I’ve granted Full Disk Access are backup apps. Others include the Finder replacement Bloom, launchers like Alfred, the wonderful selection utility PopClip, Apple’s own Pixelmator Pro, Setapp, TestFlight, Unread, Supercharge, Madden NFL 27 Arcade Edition, Hazel, and many others.

Half of the apps on this list have no reason whatsoever to be granted full disk access, and should not have it. If anything, this change might encourage developers to limit their products to only the access they actually need.

Some further context, this is in the wake of an exploit with Meta’s LLM agent.

My god. We've truly learnt nothing about security in all these years.

ndegruchy | a day ago

Good. At least someone is considering the reach of local agents being able to access everything on the disk.

fazalmajid | 10 hours ago

Except you can't disable Apple Intelligence in macOS 27, and it has full access to everything on your Mac, so the motivation may be kneecapping AI competitors under pretence of protecting your privacy.

https://mjtsai.com/blog/2026/10/01/i-said-no-and-apple-said-yes/

Apple is an advertising company (the so-called "Services" revenue, along with the App Store tax), and thus inherently untrustworthy. They just have better privacy-washing marketing than the other Big Tech.

I’m unfamiliar with some of the tech stack at $WORK so I use Claude to navigate it. It’s very good at this sort of thing.

The Claude desktop app for MacOS was becoming more and more insistent on escalating privs that I ended up deleting it. It turns out that the web app works great if you add it to the dock from safari. It’s functionally identical to the desktop app but it doesn’t continually ask to install “plugins” in MacOS.

I used Claude code for a while, it is an excellent search engine for our large existing code base, but they took all the default guardrails away, so an innocuous prompt can have it write code, compile and attempt to run it, without permission.

I absolutely hate it. Using the products of these awful companies is bad enough. Giving them access to all my data is just asking for trouble.

While I work 100% remote from home, I find it convenient to have a separate machine for work. They don’t want me to use the work machine for personal stuff, which is fine since they paid for it. This strikes both ways; I don’t want the work machine to have access to my home network, so it gets its own access point. I also don’t have any personal data on the work machine. I do have a few accounts I use in both contexts (GitHub, iCloud, etc) that I’ve been thinking of changing so agents on my work machine don’t have access to my personal accounts however.

Maybe, instead of reminding people that these controls are not necessarily for the experts every time, we need to come up with a catchy phrase. What do y'all think about:

  • "But yo momma has malware!"
  • "Won't somebody think about the parents?"
  • "I am glad YOU are unaffected!"

Or maybe we just need to identify the bias more clearly...this is probably either https://en.wikipedia.org/wiki/Curse_of_knowledge or https://en.wikipedia.org/wiki/False_consensus_effect

The first seems to fit better but neither seems to be really on point.

This is great! I feel we are long due for something like this in Linux land. Flatpak is very close, but isn't the best way to package non-GUI applications.

There are plenty of sandboxes, whether running in Firecracker microVMs, under gVisor (which has just been transferred to CNCF) and so on. If anything we are beset by the tyranny of choice, just as with desktop environments.
