macOS: Impossible to open plink2

[Will-Tyler]

Description

I am trying to run plink2 on my MacBook Air. I downloaded plink2 from here by selecting the download link for Alpha 5.14 final for macOS M1.

When I try to run plink2 (./plink2), macOS displays a message saying that Apple cannot verify that plink2 does not contain malicious software and that the software needs to be updated.

Compile from source if you are concerned about this.

It is not just a concern. macOS will not let me run the downloaded plink2 because of this.

I was able to install a working plink2 through brewsci/bio, which I learned about through #253, not through any documentation.

In my opinion, this issue should remain open because the installation instructions do not work.

Apple has recently made this harder for users, but no, it's not impossible. If it ever becomes impossible, I may stop supporting macOS.

For macOS, do this:

1. try to run plink2 (or 1.x) and let it throw an error
2. then in Settings go to Privacy and Security, scroll down until you see a comment about plink2 being blocked, click Allow Anyway
3. you should now be able to run plink 2 (or 1.x)
