Mac Os X Mojave Library Operation Not Permitted Rating: 4,3/5 244 reviews

After updating my OSX to Mojave, it seems I am no longer able to edit my crontab. Tmp/tmp.X: Operation not permitted”. Browse other questions tagged mac-osx.

Jan 15, 2019  Help Please. Im backing my iPhone X up to my Mac Book Pro using iTunes 12.9. Also Im running Mojave. I watched all the videos on how to get to the 'Library' then 'Application Support' and then to 'Mobile Sync.' I then copied the 'Backup' folder to my External Hard Drive. I then Erased. This worked like a charm. I've tried sudo killall -INFO mDNSResponder over and over to no avail. Thanks for the code.

gistfile1.sh
Load up Terminal (Applications > Utilities > Terminal.app) and type the following.
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
To turn it back on, just do the opposite:
sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist

For me sudo killall -HUP mDNSResponder works (http://support.apple.com/kb/ht5343).

Does not seem to be possible with macOS when SIP is enabled.

@slhck yes, same here, on macOS Mojave.

Whatever the case may have been, up until Lion (OS X 10.7), you simply opened your Home folder to access the Library folder.But after upgrading to Lion, OS X 10.8 Mountain Lion, OS X 10.9 Mavericks, and yes even OS X 10.10 Yosemite, the first time you tried accessing your personal Library folder, you likely found.well, you didn’t find. Can't find library folder on mac. Or maybe a developer asked you to delete a preference file, or grab a log file, while troubleshooting a program.

Takes two reboots, but you can turn off sip, restore dns to sanity and then turn sip back on: Instructions here: https://www.imore.com/how-turn-system-integrity-protection-macos
