"Downloading Originals"
Deleted old library (originals on iMac). Installed Catalina fresh 10.15.2. Turned on iCloud library to download all originals to my mac.
7 days thus far. Not bad given size of library. Face analysis complete. However, I still see that a relatively small number of files are showing up as needing to be downloaded. It's been on this number for three days now.
