Disabling SIP

Modern machines running MacOS have a security feature that shields of the memory of processes from other processes. Depending on your machine you may have to disable SIP.

For M1 macs it is required to disable SIP.

⚠️ CAUTION ⚠️

Turning off SIP allows any program with sudo privileges to modify memory contents of other processes. If you use pirated software, or other unverified apps, DO NOT DO THIS for your own safety! See the following stackoverflow post for some more info: https://apple.stackexchange.com/a/412281.

A guide for disabling SIP can be found here: https://developer.apple.com/documentation/security/disabling_and_enabling_system_integrity_protection
