Hi guys, Never come across this issue when I switch to a new 2021 MBP 14" M1PRO.(base setup) Happens quite often when I'm saving my blender file, pops up an error saying not enough space. (where after migration I should have about 250GB still.) After going through the storage management tab I came across the " Library - Caches - Cloudkit - com.apple.bird" is eating up 251 GB of storage. I've tried to delete the folder, it pops back right away. and gradually increase it's size till it's full again. Strangely, if I leave the laptop overnight, sometimes the storage will clean up by itself again. Yet, it will continue a behavioral loop on daily basis to a point it's not useable for a new MBP. Does anyone have any idea what it could be or any solutions? greatly appreciated!!
