MacOS Catalina: Slow by Design?

> This is not just for files downloaded from the internet, nor is it only when you launch them via Finder, this is everything. So even if you write a one line shell script and run it in a terminal, you will get a delay!

> Apple’s most recent OS where it appears that low-level system API such as exec and getxattr now do synchronous network activity before returning to the caller.

Can anyone confirm this? Because honestly this is just terrifying. I don't think even Windows authorises every process from a server. This doesn't sound good for both privacy and speed.

There are two new Security/Privacy Settings that I just noticed last night.

"Full Disk Access" to allow a program to access any place on your computer without a warning. A few programs requested this, so it looks like it's been around for a while.

The other one is "Developer Tools" and it looks pretty new. The only application requesting it is "Terminal". This "allows app to run software locally that do not meet the system's security policy". So, my reading of this is that in Terminal, you could run scripts that are unsigned and not be penalized speed-wise.

I don't see it on macOS 10.15.4 (19E287). The full list of categories on my Privacy tab:

  - Location Services
  - Contacts
  - Calendars
  - Reminders
  - Photos
  - Camera
  - Microphone
  - Speech Recognition
  - Accessibility
  - Input Monitoring
  - Full Disk Access
  - Files and Folders
  - Screen Recording
  - Automation
  - Advertising
  - Analytics & Improvements

Granted I don't typically use Terminal.app (iTerm 2 user), so I launched terminal and did some privileged stuff. Had to grant Full Disk Access to, say, `ls ~/Library/Mail`, but "Developer Tools" never popped up.

Are you running a beta build or something?

Update: Okay, I checked on my other machine and that one does have it (Terminal is listed but disabled by default). What in the actual fuck?!?

You can make the category appear and put Terminal in it with this command:

sudo spctl developer-mode enable-terminal

I'd be nice if this was documented somewhere :/

I was going to be that guy and say “man spctl”, but that usage isn’t listed there. If you run spctl with no arguments, it will tell you, however. The man pages on macos really do leave something to be desired.
