Hi ,
There are two question which is about mac operating system question, kindly give suggestion about it. Thanks.
1 - Other than Internet Recovery, Option-Command-R, no, to my knowledge there's isn't. For suggestions, see:
If you can't start up from macOS Recovery - Apple Support
2 - It depends what you mean by "affect". Disabling the SIP opens your Mac to potential malware or other issues, but in and of itself it does not affect the operation of your Mac.

Regards.

This key combination is only for Intel Macs.
If you have an M-series Mac, then you access Recovery Mode using the instructions in the following Apple article:
Even though your questions have been correctly answered, I would be concerned about the reason you are wanting to shut off SIP. If this is to install some software package, I would think twice about doing it. It would suggest that it is attempting to install some Kernel Extension that may impact the performance of your Mac and also may be very difficult to remove.
Modern apps have no need to disable SIP to be installed and can contain all their needed files in the Application Bundle. Using this method, simply dragging the app to the Trash will remove all the files without having to use an uninstaller that many times fails to remove all the files.
<<. It can not go Recover mode by command + R shortcut key. >>
That keyboard shortcut is an alternate way to START UP your Mac, Instead of loading MacOS. It works ONLY when your Mac is Staring Up from ShutDown or Restart.
It is ignored, by design, in fully up-and-running MacOS.
So, the questions you asked have been answered...but perhaps you could consider explaining what outcome you are trying to achieve, and maybe you would get good advice instead of just specific answers to specific questions.
I'm sorry, that makes no sense to me. Cronjobs are a user-controlled function that anyone can set up using the command line tools or editing the crontab file. SIP make the main OS System root folder as well as others like /bin and /sbin immutable.
The two are not related, unless you are trying to write a cronjob that is going to modify a System-protected file...?
Hi g_wolfman
Thanks, I try practice cronjob setting at home, but mainly I need setup in the company.
During testing process, I found it's necessary to disable SIP function.
