Cannot install Xcode 10 Network Link Conditioner in macOS Mojave

Question

I'm using the final version of Xcode 10 on macOS Mojave beta 11. I downloaded the Additional Tools for Xcode 10 package from Apple's website .

When I try to install the Network Link Conditioner Preference Pane, Settings.app displays this error:

“Network Link Conditioner” preferences is installed with macOS and can't be replaced.

However, the preference pane is not visible inside Settings.app. I even checked under /Library/PreferencePanes - it's not there.

How can I get around this?

Answer 1

I ended up manually copying the .prefPane file to:

/Library/PreferencePanes

After restarting Settings.app, it finally appeared on the list and worked perfectly.

As Martijn Scheffer stated in this comment , the reason for the pane not appearing in System Preferences is that the installer incorrectly puts the file to ~/Library/PreferencePanes instead of /Library/PreferencePanes .

Download in https://developer.apple.com/download/more/ Additional Tools for Xcode 10.1

Answer 2

Network Link Conditioner is already installed but you can't see it on the Settings App. This worked for me:

1. Press Command + Space to open spotlight
2. Search for Network Link Conditioner
3. It will appear on the result, click on it and it will open Settings app.
4. Network Link Conditioner is now visible in the Settings App. Open it from the Settings app.

Hope this helps!

Answer 3

+1 to brainray, what worked for me was:

1. Download new Network Link Conditioner
2. Replace the old one in /Library/PreferencePanes
3. Open Network Link Conditioner directly from /Library/PreferencePanes

It now appears in my Settings app

双击Additional_Tools_for_Xcode_x.dmg的Network Link Conditioner.prefPane为我工作 - 在请求安装权限后它出现在设置中。
