 ### Installing Prerequisites
 
-Because Windows ships with an embedded version of Python, if you want to install plugins inside that Python, you'll need to either adjust your `sys.path` to include the locations for the other libraries (making sure they're compatible with the built-in version), or else install them directly in the environment via:
+Because Windows and MacOS ship with an embedded version of Python, if you want to install plugins inside that Python, we recommend instead installing an official [python.org] (NOTE: ensure you do not accidentally install a 32-bit build) version, or a [homebrew] Python 3.x build.
 
-``` py
-import pip
-pip.main(['install', '--quiet', 'packagename'])
-```
+Then, you can adjust your [python.interpreter setting] to point to the appropriate install location. Note that the file being pointed to should be a `.dll` or `.dylib` though homebrew will often make the files not have any extension. For example:
 
-_--quiet is required to minimize some of the normal output of pip that doesn't work within the context of our scripting console_

-Binary Ninja can also switch to a different installed version of Python using the [python.interpreter setting].
+Note that using `pip.main` is no longer supported by the pip maintainers therefore this previous approach to installing dependencies is not currently supported.
