If you just use SwitchResX for any other feature and don’t plan to alter your list of resolutions, then you can leave System Integrity Protection turned on. To re-enable SIP, boot back into the recovery partition and set state to enabled: You can then reboot normally on your standard macOS system partition.

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)

While Apple still do provide drivers in El Capitan for cards like the Radeon HD 7950 and HD 7970 Apple never officially sold these cards. Sadly Apple have a long reputation of producing only mediocre drivers at least in terms of performance and features, generally they work well enough. Therefore the information in many but not all cases does not apply to real Macs.įor real Macs running OS X only Apple provide official drivers for AMD video cards. The information on the tonymacx86 website is aimed at people building what are colloquially referred to as 'hackintoshes' which are not real Macs.
