Can Anyonew Tell Me What MT Mapping (0x40000006aecf3 --> 0x1150d6, 1, C) is not Completley Refrenced Error Message Means In First Aid on the new Catalina os using mac mini
Mac mini, macOS 10.15
If the error is associated with a snapshot, then it should correct itself once the snapshot is removed by the system. If the error is not associated with a snapshot and Disk Utility cannot repair it, then the only option is to erase the whole physical drive and reinstall macOS or restore from a backup.

That is not good to hear. I have Catalina installed and my system is very slow with a lot of beachballing.
Running Disk Utility, I get the MT error:
warning: MT mapping (0x40000004e844d -> 0xd48fb2, 1, C) is not completely referenced
warning: MT mapping (0x40000004e8580 -> 0x1adc485, 4, C) is not completely referenced
Too many warnings of this type generated; suppressing subsequent ones.
hi
finally got rid of mapping errors took my mac mini into apple store and they told me that i had to clean the drive completely and put a clean install of catalina in so i did that and it did get rid of mapping errors but it took me an additional 9 days running 24/7 to get the music app to show my music library but bottom line is you need to do a clean install of catalina to clear errors
hope this helps someone else in mean time many thanks for everyone’s input
This problem also shows on my iMac late 2012 after Catalina update....
sorry to hear that but at least i know i’m not the only one. now the big question is still how to get rid of it either way Thanks much appreciated
