Once I begin up a recent executing Mathematica on my MacOS system and I open a Pocket book file there’s at all times one image outlined within the International context. This image is $MySource and it factors (through a listing symbolic hyperlink) to my default location for numerous pocket book and package deal information.
I do not bear in mind setting this up however I should have because it factors to an iCloud folder that I actually created. I’ve searched all preferences and different areas corresponding to account outlined setting variables and I am unable to discover this definition wherever. I’ve searched the documentation for $MySource and MySource but it surely results in numerous content material entries and none of these appear to include the strings $MySource or MySource.
If I modify it to one thing totally different then once I shutdown Mathematica and begin it up once more it returns to the unique definition to via the listing hyperlink.
How do you set this worth and does it have any particular objective apart from offering a default file lookup location?
