Before OS X El Capitan came out it was easily possible to hide the Python app from the dock when you run a python script. Since El Capitan is out, this is not the case anymore. If I try to edit the Info.plist with root permission it still says that the file is in read-only mode. I even tried to log in as root and then edit it but it doesn't help.
I run a few python scripts via crontab.
Does anyone have a solution for hiding Python? I'd appreciate it.
The problem has to do with different permissions associated with sudo in OS X El Capitan. Some areas are by default non-sudo-able after upgrade due to a feature called "SIP" (System Intregrity Protection). The accepted answer on this question solves the issue.
