This can also occur when migrating from a version of OS X/MacOS that didn't require signed mdimporters (usually provided by apps claiming file name suffixes). They'd be found in /Library/Spotlight/ and they can be deleted by sudo from someone with administrator access. Like throwing a switch and those messages stop in the system log.


Found out by forcing a Spotlight re-index and got a pop-up message saying the UID mdworker.shared.0A000000-0500-0000-0000-000000000000 or so, the second numerical field would be a volume that can't be scanned by an unsigned mdimporter and the process gets killed (too fast for you to get the identifying info in the Activity Monitor).


The one I recall adding in Mavericks was epub.mdimporter (an archive). Managed to pass all the way through the Migration Assistant for Big Sur 11.1 (on a Macbook Air M1).


Getting rid of the messages made my day.

@steve626

totally agree with HWtech


Excellent post and advice… particularly amongst a typical collection of colourful, emotional, dumb, delusional, desperate

etc etc type responses which inevitably appear on these threads. Great bedtime reading if you are having trouble getting to sleep & you can’t get to a pharmacy for some decent sleeping medication.


Jokes aside, I’ve been using Mac’s for years and have owned several models over the years but tonight I happen to be unboxing and setting up a brand new iMac Model A2115 shipped with BigSur version 11.1


After working my way through the setup assistant including iCloud login the first thing I did was check System Preferences for an update.


Whilst waiting for the latest Big update to download I went into system report to remind myself of the machine specs etc & for no specific reason checked out the system logs… hence why I found this thread because my machine is spewing out the same repetitive SigKill etc junk that everyone else has encountered.


So just thought I’d throw my two cents worth in that it’s happening on a 100% brand new iMac with zero applications installed other than what it was shipped with.


No idea whether this IS actually an issue that I should be concerned about or not as you’ve subtly suggested but given my machine is out of the box I’ll submit the feedback to Apple so it is documented & on the record if it does turn out to be something potentially detrimental to a piece of tech I’ve parted with a nice wad of cash for…
