Method 1: Disable System Integrity Protection (SIP)

  • Reboot your Mac and then press & hold Command + R keys to boot your phone into recovery mode during the restart.
  • Click on Terminal
  • Enter the following command to temporarily disable SIP on your computer. On the next time, you reboot your device, it will automatically enable.
csrutil enable --without debug
  • Type in the following command to turn off SIP completely:
csrutil disable
  • Type in Reboot

Once you disable SIP, you will no longer see apps get crashed on your Mac.

Method 2: Run Commands Through Terminal

  • First, you need to install command line tools. This command only runs for one time. If you have previously installed it, just skip this step:
xcode-select --install
  • Next, continue to run the following command:
sudo codesign --force --deep --sign - /Applications/name of the error
  • Finally, enter your device passcode and hit Enter.


If the app name has space, you need to add “\” into space. For example, Cleanmymac X is written into CleanMyMac\
