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

  - 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.

This does not make the "developer tools" panel show up in my machine :( tried everything already

I don't see it on my machine. Do you happen to have System Integrity Protection disabled?

No, SIP is fully enabled on both the machine with the Developer Tools category and the one without.

Interestingly, I rebooted the machine without after some benchmarking and experimentation with syspolicyd (see https://news.ycombinator.com/item?id=23274903), and after the reboot the category has mysteriously surfaced... Not sure what triggered it. Launching Xcode? Xcode and CLT were both installed on the machine, but I'm not sure when I last launched Xcode on this machine. Another possible difference I can think of: the machine without was an in-place upgrade, while the other one IIRC was a clean install of 10.15.

In the worst case scenario, you can probably insert into the TCC database (just a SQLite3 database, located at ~/Library/Application Support/com.apple.TCC/TCC.db) directly:

  INSERT INTO access VALUES('kTCCServiceDeveloperTool','com.apple.Terminal',0,1,1,NULL,NULL,NULL,'UNUSED',NULL,0,1590165238);
  INSERT INTO access VALUES('kTCCServiceDeveloperTool','com.googlecode.iterm2',0,1,1,NULL,NULL,NULL,'UNUSED',NULL,0,1590168367);

(Should be pretty self-explanatory. The first entry is for Terminal.app, the second entry is for iTerm 2.)

Back up, obviously. I'm not on the hook for any data loss or system bricking.

Does this not require disabling SIP?

Yes. I got mine to appear through mysterious yet fully SIP-enabled means, but if all else fails for you you can temporarily disable SIP to change this.

Maybe you need Xcode, try running "mkdir /Applications/Xcode.app"

As mentioned in a reply to a sibling, Xcode has been installed (for like five years) on this machine, and launching it doesn't help. The next step would be to compile and run an application with it, which I haven't bothered.

I would expect checks for Xcode to go through xcselect rather than a simple directory check. Installing the command line tools (sudo xcode-select --install) might actually be a better idea to test this.

I thought the same, but actually this method worked for me when I wanted the the Spotlight "Developer" option to show up (the CLT were already installed). I have the Developer panel under "privacy" as well, even if I never installed Xcode on my machine

Maybe if you ran Terminal.app once it would work?

(I'm also on 10.15.4 (19E287))

No, I played around with Terminal.app for quite a while already. Actually the category does show up on another machine of mine (see edit)... I suspected that maybe I never ran Xcode on the first machine since I upgraded to Catalina, so I launched Xcode, but again, no luck. I'm at a complete loss now.

Terminal actually gives an error if you poke into the top level library folder with full disk access disabled, no prompt to change without me looking on stack overflow for the solution.

I wonder what "Developer Tools" grants in practice. Clicking the (?) for viewing built-in help does not mention this particular setting, it skips right over it going from "Automation" above it to "Advertising" below it.

I believe it means the process will no longer check for the Quarantine xattr.

But the quarantine xattr has nothing to do with checking notarization?

via https://lapcatsoftware.com/articles/catalina-executables.htm..., I've added an entry in my /etc/hosts to block requests to api.apple-cloudkit.com:

    127.0.0.1 api.apple-cloudkit.com
    127.0.0.1 *.api.apple-cloudkit.com

Full Disk Access was added in 10.14 (2018), so it's relatively new.

I'm using the Kitty terminal, and observed the script launch delay described in the blog post. After adding Kitty to "Developer Tools", the delay disappeared. Thanks!
