If you use spaces instead, the synthetic firmlink won’t be created.Īfter the reboot, you should see a symbolic link named installers at the root level of the boot volume. When creating the separation between installers and Users/Shared/installers in the /etc/nf file, you need to use tabs. Note: Whomever designed this came down on the “tabs” side of the “tabs vs. Add the following entry to the /etc/nf file: Create the /etc/nf file if it didn’t already exist.Ģ. To create a symbolic link at the root level named installers which points to /Users/Shared/installers, I would do the following:ġ. To show how this works, I’ve created a directory containing installer packages located at /Users/Shared/installers. Instead, it is the next directory level down. Note: In those cases where you’re creating a symbolic link and are including a path, the start point for the directory path is not /. After all desired entries have been made, save the /etc/nf file.įor example, /etc/nf may look like this: In /etc/nf, define the name(s) of the empty directory or symbolic link you want to have appear at the root level.Ĥ. Make sure /etc/nf has the following permissions:ģ. Create a file in the /etc directory named nf.Ģ. To create a synthetic firmlink, you need to do the following:ġ. For more details, please see below the jump. These synthetic firmlinks are how the OS enables folks to create directories and symbolic links on the read-only boot volume. The use of firmlinks is exclusively reserved for the OS’s own use, but Apple has also made available what are called synthetic firmlinks. Firmlinks are new in macOS Catalina and are similar in function to Unix symbolic links, but instead of only allowing travel one way (from source to destination) firmlinks allow bi-directional travel. To address this need, Apple added a new method for creating directories at the root level which leverages Apple File System’s new firmlink functionality. For users or environments which were used to using adding directories to the root level of the boot drive, this change meant they could no longer do that. That is, if and only if, the function return value indicates failure.One of the changes which came with macOS Catalina was the introduction of a read-only root volume for the OS. I also demonstrated how to obtain that error code, and also when to do so. This allows us to capture the error code in case of failure. Note that I added the SetLastError parameter to the DllImport attribute.

The following code is something simple that I wrote up using the Win32 API, but does not seem to be working: Imports
