Apple still does this kind of crap.

Not for users who've opted into two-factor authentication: https://support.apple.com/en-us/HT204915

From the page:

Do I still need to remember any security questions?

No. With two-factor authentication, you don't need to choose or remember any security questions. Your identity is verified exclusively using your password and verification codes sent to your devices and trusted phone numbers. When you enroll in two-factor authentication, we will keep your old security questions on file for two weeks in case you need to return your account to its previous security settings. After that, they will be deleted.

> Some parts of the filesystem become off limits, even as root. But installers have access!

Point of clarification: only Apple-signed installers can modify system paths. (c.f. https://support.apple.com/en-us/HT204899) All other installers are subject to SIP restrictions.

And Apple only added a few simple steps for people eager to tinker: reboot and disable SIP. Or reboot into the installer for the other OS with which you prefer to tinker. Or create a VM with an experimental OS. Frankly, most of those steps existed before SIP.

Most users shouldn't care or notice, and will benefit from increased protection. People who want to tinker will (and can and should!) tinker.

> Apple can [sic] starts using the new Trusted Computing[4] features on new CPUs (such as SGX[5]), good luck regaining control.

It seems the apocalypse came to pass a while back, with the Secure Enclave in Apple's A7 processors.

> Of course, they know how to disable the restrictions or install a jailbreak, so these problems don't apply to the technological priesthood - it's normal people that have to live with the restrictions.

Here's the funny thing: normal people benefit from those restrictions. Without them, their devices – the ones you insist they should own – would quickly become someone else's: the attacker's. It would be awesome if people started thinking about long-term consequences.

Honest question: do you hate root? Should all processes run with equal privileges? Does the kernel have an evil and undesired permissions level?

I'm idly curious: what were your "symlink issues with /usr/bin/"? As with other unices, /usr is system-owned and anything not under the /usr/local hierarchy may be modified or destroyed during OS upgrades.

Very few people should ever need to disable SIP – and that includes almost all developers! Are you building/running unsigned kexts? No? Then you almost certainly don't need to disable SIP.

Most instructions that no longer work with SIP enabled should be modified so they don't conflict with SIP. As a bonus: changes resulting from those instructions are far more likely to be preserved across OS X upgrades.

If you're looking to hide your activity from malware, you should be incredibly excited by SIP. With SIP enabled, you have more protection from malware introspecting other processes or monitoring activity on the system. Hell, if you're a researcher building tools to detect and analyze OS X malware, you'd likely benefit from SIP by opting-in your tools to SIP's restrictions. (Tangential example: Chrome is taking this step; Canary is currently SIP restricted.)

Malware can only introspect SIP-protected activity by employing kernel exploits. If malware can compromise the kernel, it's game over. You're not going to hide anything, ever.

If anything, it sounds like you want SIP's purview expanded to encompass more of OS X.

Improved privacy is one benefit https provides. There are two other benefits worth considering: authentication and integrity. Without https, there is no way trust a site's identity, and no guarantees the data you're receiving was not modified in transit.

Don't forget to weigh those other two factors when judging https adoption. Your goals are understandable and worthwhile. They're also still achievable with appropriate client management software.

Consider this: in a world without https, your children could visit a valid, approved domain and be served malicious or undesirable content because someone modified the content in flight or intercepted the connection. There is literally no way for you to have any guarantee what's served to your children.

In a world with https (and appropriate client management software), you can be confident they really are only receiving approved content because the connection is authenticated and traffic cannot be modified in flight. (And your children are less easily tracked by unknown 3rd parties, to boot.)

Authentication and integrity are often forgotten when discussing https, which is unfortunate because those are two incredibly important benefits that further motivate widespread https deployment.

The "pcapd capability" is iOS's remote virtual interface.

https://developer.apple.com/library/Mac/qa/qa1176/_index.htm...

  OS 5 added a remote virtual interface (RVI) facility that lets
  you use OS X packet trace programs to capture traces from an
  iOS device. The basic strategy is:
  
  1. Connect your iOS device to your Mac via USB.
  
  2. Set up an RVI for that device. This creates a virtual
  network interface on your Mac that represents the iOS device's
  networking stack.
  
  3. Run your OS X packet trace program, and point it at the RVI
  created in the previous step.

If you don't pair the iOS device with the Mac, the technique won't work.

It was signed with a Developer ID; thus, by definition, it could not have been distributed in the store.

Anything distributed through the App Store is signed by Apple. Developer ID signed binaries can only be distributed outside of the store.
