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:

Answer 1

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>

Answer 2

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..

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>
            <false/>
            <key>class</key>
-           <string>user</string>
+           <string>rule</string>
            <key>comment</key>
            <string>For use by Apple.  WARNING: administrators are advised
             not to modify this right.</string>
            <key>default-button</key>
            <dict>
            ...
            </dict>
            <key>default-prompt</key>
            <dict>
            ...
            </dict>
-           <key>group</key>
-           <string>_developer</string>
            <key>shared</key>
            <true/>
-           <key>timeout</key>
-           <integer>36000</integer>
+           <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>
        </dict>

Answer 4

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)

Answer 5

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

Answer 6

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.
