MacOS Catalina: Slow by Design?

> This is not just for files downloaded from the internet, nor is it only when you launch them via Finder, this is everything. So even if you write a one line shell script and run it in a terminal, you will get a delay!

Can anyone confirm this? Because honestly this is just terrifying. I don't think even Windows authorises every process from a server. This doesn't sound good for both privacy and speed.

There are two new Security/Privacy Settings that I just noticed last night.

"Full Disk Access" to allow a program to access any place on your computer without a warning. A few programs requested this, so it looks like it's been around for a while.

The other one is "Developer Tools" and it looks pretty new. The only application requesting it is "Terminal". This "allows app to run software locally that do not meet the system's security policy". So, my reading of this is that in Terminal, you could run scripts that are unsigned and not be penalized speed-wise.

I wonder what "Developer Tools" grants in practice. Clicking the (?) for viewing built-in help does not mention this particular setting, it skips right over it going from "Automation" above it to "Advertising" below it.

I believe it means the process will no longer check for the Quarantine xattr.
