Time Machine errors since upgrading to High Sierra?

Since upgrading to High Sierra, I've seen several errors listed in the log.

I use the following Terminal command to view the log:

log show --predicate 'subsystem == "com.apple.TimeMachine"' --info | grep 'upd: (' | cut -c 1-19,140-999

Does anyone see errors like this???

The "failed to remove attribute" error happens with each backup.

The "iterating sibling links" error happens occasionally (once or twice a week).

These errors happen on an iMac 5K 27" with a Fusion drive. I have rebuilt the iMac, run diskutil in recovery mode, never found any real errors aside from these with started after the upgrade to HS.

Anyone else see stuff like this????

I'm having problems with the sibling links on my iMac 27" 2017, but I suspect that the back-up drive I have is defective: It will periodically complain that the backup failed.


On my MacBook Pro, I am not seeing any "iterating sibling links" errors.


On both, I'm getting the "Failed to remove attribute" errors.

User-centric queries/comments such as this are perhaps best put to AppleCare's public community support forums, Apple's twitter support account and/or Apple’s YouTube Support Channel vs. risking off-topic here in the DevForums, thanks and good luck.
