Wrong delimiter setted in csvConfiguration of the writer on mac os

[filippoptg]

Describe the bug
When i try to export a csv from a mac I have two problems
The first is that the entire row of data, except header, is inside the quotes as I show you in the row's example below
"examName.2442ae72-d939-efa7-3e0b-01b39a03e89b.name.surname.Male.""06/07/2020 09:18:27.719"".""28/08/1994 10:00:00.000"".""06/07/2020 09:19:07.333""".
From here I describe the second problem, which is regarding the delimiter, since I expect it to be the semicolon
In the configurations of the writer I set delimiter to ";"
var config = new CsvConfiguration(CultureInfo.GetCultureInfo("it-IT"))
{
NewLine = "\r\n",
Delimiter = ";"
};
But when I go to see the csv that has been created, it presents as a delimiter the dot, as can be seen in the example line above.
I therefore assume that the first problem I mentioned - the entire line is inside the quotes, precisely because of the delimiter being seen as a dot - is a result of the wrong delimiter.

Anyone can show me a solution? Thanks
