Open geth (and other) binaries on MacOS

Recently, I had a problem opening the geth binaries (one of the Ethereum execution clients) on macOS.


After a short internet search, I found it was caused by extended attributes check. The problem like that occurs when the unsigned software is downloaded from the internet, but only using a web browser. When the curl or wget commands are used, there are no extended attributes assigned to the file.

 To check if the file has extra attributes, you can run a simple `ls -l` command and look for the `@` character.

> ls -l
-rwxr-xr-x@ 1 wawrzek  staff  45986920 17 Apr 07:06 geth
The list of attributes can be obtained with the `xattr` command:
> xattr geth
The same command can be used to remove the attribute
> xattr -d geth
what enables an application to run.
