[Solved] Appium+Xcode+ios:ideviceinstaller -l: “Could not connect to lockdownd. Exiting.”

1. Attempt to modify permissions:

sudo chmod -R 777 /var/db/lockdown/


2. Try the most online solutions:

brew uninstall ideviceinstaller -g

brew uninstall libimobiledevice -g

brew install --HEAD libimobiledevice -g

brew install ideviceinstaller -g

Report an error directly…. Failure

3. Try another solution, one of which successfully solved my problem:

Method 1:
brew install --HEAD ios-webkit-debug-proxy -g

brew install ios-webkit-debug-proxy -g
still fail...

Method 2: brew uninstall -f libimobiledevice ideviceinstaller usbmuxd if the command is rejected, you can follow the prompt and update the command to.
 brew uninstall --ignore-dependencies libimobiledevice ideviceinstaller usbmuxd
👌 This time the command was successful
👌 Then it continues.
brew install -v --HEAD --fetch --build-from-source usbmuxd libimobiledevice ideviceinstaller
ideivesinstaller -l
