If you like DetectX Swift and want to integrate it with Munki, this is how I did it. Hat tip to Zack McCauley for doing the heavy lifting, which I'm now building on. I'd recommend you read his blog post first.
So instead of having an Outset script or separate Launch Agent, I decided to put the DetectX Swift scan as part of the Munki run (specifically a script in the preflight.d directory that MunkiReport creates):
#!/bin/bash
# Run a DetectX Swift scan
/Applications/Utilities/DetectX\ Swift.app/Contents/MacOS/DetectX\ Swift search -aj /usr/local/munki/preflight.d/cache/detectx.json
Outside of MunkiReport (but connecting to the MunkiReport MySQL database), I have a script that generates a Python list of files that DetectX Swift has flagged as "issues":
$query="SELECT issues FROM detectx WHERE numberofissues > 0";
$result=mysqli_query($YOURDATABASECONNECTION, $query);
if(mysqli_num_rows($result)>0){
// Create an array to store the results
$larger_issues=array();
while($row=mysqli_fetch_assoc($result)){
// Create an array based on a semi-colon delimiter
$smaller_issues=explode(";", $row['issues']);
foreach($smaller_issues AS $smaller_issue){
if((trim($smaller_issue)!='') AND (!in_array($smaller_issue, $larger_issues))){
array_push($larger_issues, $smaller_issue);
}
}
// End fetching results
}
if(!empty($larger_issues)){
echo '<p>okay_to_delete = [ ';
$counter=0;
while($counter+1<count($larger_issues)){
echo '\'' . $larger_issues[$counter] . '\',<br />';
$counter+=1;
}
echo '\'' . $larger_issues[$counter] . '\' ]</p>';
//print_r($larger_issues);
// End checking there are elements in larger issues (there should be)
}
// End checking there are any issues
}
And finally I have a nopkg to do the actual cleaning of the issues DetectX flagged.
So why even have an array of okay-to-delete things?
Well, DetectX Swift has command-line options to scan, but it (at least as of this writing) does not have the option to command-line remove things, presumably so someone has a chance to review the things removed before actually removing them. Also, since it's just forcefully removing things (yes, I know about using shutil to remove, but I've run into weird situations in which that doesn't work consistently, so I'm using a subprocess to invoke rm instead), it's probably a good idea for at least one human to review things before they get removed.
The nopkg also copies the .json to /var/log (with a datetime stamp in the name) before removing anything.
For example, here's a machine that's on macOS 10.13.4.
softwareupdate can't find any updates.
And even if you try to manually install the 10.13.6 combo update, you get macOS High Sierra 10.13.6 Update can't be installed on this disk. This volume does not meet the requirements for this update.
And, yup—lo and behold! The FileVault encryption is still in progress. Once that's done, the 10.13.6 update should install just fine.
