2018 Intel MacBook Pro with a Bootcamp partition here, can confirm, my MacBook has been a mess since upgrading to 12.5. It has crashed to the point of rebooting several times on its own since the upgrade. I think that has only happened once or twice before this in 4 years of ownership.


Crash logs in Diagnostic Reports indicated mdsync to be to blame. When not crashing CPU was through the roof, with UVFSService and numerous spotlight related services such as mdsync, mds, md_stores, and mdworker_shared taking up way too much CPU. The fan was running at max all the time and computer was unusable.



Excluding the Bootcamp partition from Spotlight seems to have resolved my issue. CPU is back to normal and the fan is no longer running constantly.
