Stop "developer tools access needs to take control of another process for debugging to continue" alert

Question

I recently upgraded to 10.7.3, and when I try to debug my iOS project in the simulator for the first time after logging in, I'm prompted with the following two alerts:

My user is an admin user. I never saw these alerts before. How do I get them to stop?

EDIT

I've verified that I'm a member of the _developer group using id -a.

I believe you need to add yourself to the _developer group like this: #1838389 but if you're already part of the _developer group (as I am) then I'm not sure what's changed. I know the /etc/authorization file has changed in 10.7.3, and a few tests show that I can eliminate some of the prompts by editing that to always allow debug, but with default rules it seems to fail the _developer group test. :( I'm noting what I've found so someone else might dig up more details and make more sense of what broke. – Undeniable

lame that this was closed. – Wilhelminawilhelmine

Not sure why this was too localized; it's a duplicate of the question (with answer) found here: https://mcmap.net/q/83163/-is-there-a-way-to-remove-the-authorization-prompt-from-command-line-instances-of-instruments-xcode – Votary

This was asked first. The other is the duplicate. – Insensate

Answer 1

There's a much simpler solution for this. Try running the following command:

sudo /usr/sbin/DevToolsSecurity --enable

If you're on Ventura, see Mark's answer

Thank you! This is great. The man page for DevToolsSecurity explains exactly what's going on. – Onions

Worked for me, but why the heck did Apple add this barrier ? You upgrade from a working version of XCode, and immediately find yourself having to Google their strange error messages, trying to find out how to continue using XCode. Terrible service. – Gebhardt

Didn't work for me either: Developer mode is already enabled. – Carnal

This worked for me with Xcode 8 on an iMac running a TeamCity agent on Mac OS Sierra. – Mime

Apple is garbage. I also want to keep it disabled, yet I still have to put in Admin?? – Angevin

Worked for me with 10.2. BTW, this started popping up everytime since 10.2, not with the previous XCode versions. – Aric

Doesn't work with Eclipse CDT with GDB debugger. Developer mode is already enabled. – Gastrectomy

Answer 2

enable develoer mode: In Terminal run this: DevToolsSecurity -enable

Just running 'DevToolsSecurity' command enables it by default. Passing -enable argument is not required – Radiotransparent

Answer 3

Per Zev Eisenberg's answer, reinstalling Xcode 4.2.1 worked. However, it might be easier to just patch the /etc/authorization file with the following diff.

        <key>system.privilege.taskport.debug</key> 
        <dict>
            <key>allow-root</key>

I had done the same thing as above. The problem now is that I am not able to get internet wifi. I am not sure how this is happening. – Gers

I've tried DevSecurityTools, adding myself to the _developer group and these modifications. I'm still being prompted to give access. So far, I've not been able to find anything that removes the prompt. – Akilahakili

Changing system.privilege.taskport by executing security authorizationdb write system.privilege.taskport allow made my password prompts to disappear – Nerissa

Answer 4

I'm on macOS Ventura and receive

TL;DR

sudo dscl . append /Groups/_developer GroupMembership <username>

As per https://mcmap.net/q/82362/-authorize-a-non-admin-developer-in-xcode-mac-os

What was tried

sudo /usr/sbin/DevToolsSecurity --enable says it's already enabled.

After entering my username and password, it works but then I have to do this every time I launch the debugger.

If I run sudo security authorizationdb write system.privilege.taskport allow it prevents the prompt but only until the next restart.

I tried following the existing answers that ask you to update /etc/authorization - which has been deprecated since macOS mavericks and is now /System/Library/Security/authorization.plist but I couldn't edit this file (I even tried this) but since my $USER isn't an owner of the file so I can't force overwrite it even with sudo.

I tried

sudo /usr/libexec/PlistBuddy -c "Set :rights:system.privilege.taskport:class allow" authorization.plist

But of course, the same applies but instead this fails silently.

If I run id -a it returns 204(_developer) so I am part of the developer group even before running the dcsl command

What fixed it for me was

sudo dscl . append /Groups/_developer GroupMembership <username>

Didn't seem to work for me on Ventura. – Bukharin

@LordZsolt did you try to run sudo /usr/sbin/DevToolsSecurity --enable first then dscl – Embolism

Answer 5

Reinstalling Xcode 4.2.1 after upgrading to 10.7.3 seems to have fixed it for me.

Nevil

We will have to this once again when either Mac OS 10.8 or iOS 5.1 launch. Word is they are making the Xcode app an actual .app for ease of updating through App Store. – Tiossem

Xcode 4.3 is already delivered in this manner. I haven't had this password issue since installing it. – Nevil

Answer 6

I modified the rule for system.privilege.taskport and the alert doesn't show up anymore.

1. Open the file /etc/authorization.
2. Find the rule system.privilege.taskport. Under the line <key>class</key>, change <string>rule</string> to <string>allow</string>

Posting a diff is a little nicer. – Insensate

I've tried all the other suggestions and this is the only one that worked. Thanks. – Akilahakili

This might work but it might also open up a security hole in your sandbox. I am a bit wary. – Isabel

Thanks! But /etc/authorization is deprecated on the mavericks. Do you know what should I use now? – Remitter

Like I commented above, it also works by executing security authorizationdb write system.privilege.taskport allow in the command line. – Nerissa

I don't even have that file: /etc/authorization: No such file or directory. I am not using XCode, but Eclipse CDT with GDB debuuger, and I am having the same problems. Any idea? – Gastrectomy

Answer 7

I had same issue with my mac 10.12.5 & Xcode9 Run this command :

sudo security authorizationdb write system.privilege.taskport allow 

Then enter your password.. Check if it still prompt you. Good luck..

Vulpecula

This helped with Eclipse CDT. Thanks. – Gastrectomy

worked on macOS 12.6 monterey. – Embolism

Answer 8

I just turned debugging off in (edit scheme) -> uncheck debug executable. But I also do all of my debugging on another console, so if you are developing and need the debugger then it wont help. I only have this issue with an old version of Xcode 8.2.1 since I am running the code on an old Mac using El Capitan.

Newer mac and Xcode version 10 doesn't seem to have this issue.

Answer 9

Something has been modified on file /etc/authorization, I've a Lion without v10.7.3 and it has the following code

Lines 5807-5814

    <key>k-of-n</key>
    <integer>1</integer>
    <key>rule</key>
    <array>
        <string>is-admin</string>
        <string>is-developer</string>
        <string>authenticate-developer</string>
    </array>

After the update the file contains many modification due to new language supported but the lines corresponding to debugging authorization differ from the lines shown above in

Lines 7675-7676

    <key>group</key>
    <string>_developer</string>

I can't apply these differences to my 10.7.3 Lion installation because it's a production machine and I can't risk to corrupt it

I've all necessasy permission as shown from command id -a

uid=501(dave) gid=20(staff) groups=20(staff),
401(com.apple.access_screensharing),
402(com.apple.sharepoint.group.1),
12(everyone),
33(_appstore),
61(localaccounts),
79(_appserverusr),
80(admin),
81(_appserveradm),
98(_lpadmin),
100(_lpoperator),
204(_developer)

no need code. no need reinstall xcode. Do these steps:

1.close xcode.

2.open Keychain access.

3.double click your Keychain(the key icon which create from keychain.p12)

4.go to access control panel(name maybe not right)

5.enable all app access this.

6.save.

7.run your xcode project.

8.it works well.
