Please restart the machine for the changes to take effect. Successfully disabled System Integrity Protection. That should confirm with the following message: You boot in recovery mode by pressing CMD + R when starting up your Mac.Īnd type the command below (don't type the "#" !). ĭisabling SIP requires booting into the recovery partition. This is the case and remains true for any version of macOS newer than 10.11. You also need to disable SIP and leave it disabled to be able to install and use the SwitchResX Contextual Menu. Once the resolution has been created and activated, you can turn SIP on again. That means that if you want to use SwitchResX to add, modify, or create a new custom resolution, or a scaled Retina resolution, then you must temporarily disable System Integrity Protection before doing this. This is true for all versions of macOS between 10.11 and 10.15.1. For doing this, SwitchResX modifies a System file.īeginning with El Capitan, System Integrity Protection does not allow SwitchResX to create or modify this file. One of the most widely used features in SwitchResX is the ability to define new custom resolutions to your monitor. All later versions of macOS use the same mechanism. MacOS 10.11 « El Capitan » introduced a feature called « System Integrity Protection », aka « SIP ». Disabling SIP is still only required to install the SwitchResX Contextual Menu. if you are using macOS version 10.15.2 and newer, there's no need to disable SIP any more to install custom resolutions, but you need to use SwitchResX version 4.10 at least. if you are using any version of macOS between macOS 10.11 and macOS 10.15.1, you will need to disable SIP to install any custom resolution, and also to install any SwitchResX extension (including SwitchResX Contextual Menu) SwitchResX and System Integrity Protection (SIP)
