> I'm glad I don't have system integrity protection :-) Even if you did have SIP, you can disable it as follows:
- Reboot - Hold down the Option key until the boot menu appears - Select the Recovery System - Select Terminal from the Utilities menu - # csrutil disable - Reboot When you're back in your normal macOS, verify that SIP is disabled: $ csrutil status I expect that if you move perl aside then replace it with a symlink, it would work to reenable SIP. That is, I don't think SIP keeps hashes of anything rather than it prevents certain system calls from being used on certain files.
