I bought the new book to learn more about App debugging (and the books here are awesome!).
The first chapter begins by saying that you should disable System Integrity Protection in order to follow along. I kind of wanna do it, but isn’t this quite dangerous?
I also tried to figure out how to install mac os on a virtual machine, but all I can find are tutorials for installing it on windows.
Is it safe to disable it for some time (I know that I shouldn’t do shady things on the internet that download malicious stuff :D)? The book says it’s not very safe, but how dangerous is it for some time?
You should be able to do this using virtualbox if you don’t want to disable it on your production machine. Here’s a video I came across: Disabling System Integrity Protection under VirtualBox - YouTube . Personally I don’t see the worry since SIP is really there to prevent developers from messing with system fundamentals which could make the system unstable. Most of the apps that were doing that have worked around this by now. You can always set it back if you’re worried about leaving it permanently disabled.
If you are uncomfortable disabling SIP, then just turn it back on. After chapter 1, you can get through most of the chapters without having to disable SIP until you reach the DTrace chapters.
With SIP enabled, there’s some apps you won’t be able to attach to via LLDB, but everything on the Simulator should still be fair game, which is what the majority of the book uses to explore (haven’t checked on High Sierra yet).
In the next version of the book, I’ll add a tutorial on how to setup a VM of macOS
