Will installing XtraFinder make my system vulnerable? I am tempted to install XtraFinder on my mac because of all the features it provides but am worried that it may leave my system vulnerable to a security breach.

The installation dialog box says the following


  OS X 10.11 and later users should read about System Integrity Protection before installing.


I went to the link provided (System Integrity Protection):


  You need to partially disable System Integrity Protection. I do not encourage you to disable System Integrity Protection. It makes your computer less safe.


The warning is something to do with code injection into Finder.


Does this mean that only XtraFinder is allowed to inject into Finder?
Will this allow some other code to wreak havoc on my system?
Will   installing XtraFinder make my system vulnerable?
Go ahead and follow the directions. When you finish, re-enable System Integrity Protection and restart.
