Hi everyone, My Mac has been bugging me to delete files for a while, saying I'm running out of space. I check About > Storage, and see that the vast majority of my Mac is filled with 'iCloud Drive' files. This shouldn't happen, as I have 'optimise Mac storage' ticked in my iCloud preferences, along with all the possible checkboxes ticked. I have more than 1.5 TB free in my iCloud account, which is plenty to store all my HD. Syncing between my devices is occurring quickly, as normal. So why isn't my Mac offloading my lesser-used files to the cloud for me to download when needed? Most of them I haven't used in months. Surely, the whole point of 'optimising' storage is that I shouldn't encounter a low storage warning if I have plenty of space in iCloud? It even looks as though it is trying to download MORE files, with a down arrow and then 'waiting' underneath some old, unused folders in my Drive folder. On my iOS devices, optimising storage works like a dream. Did I misunderstand what's going on here?
