I have just upgraded OS X and opened the new Photos app to import my Aperture library. Everything went well (Photos work fine) but I am surprised to see that I didn't loose 100Gb free space on my HDD.
My Aperture library is still there, and takes 100Gb+. When I read information on the new Photos library, it also says 100Gb+. However Daisy Disk shows the following report:
- Aperture library: 117 Gb
- Photos library: 15 Gb
Are there some "symlinks" involved in the background? Are photos being slowly copied (100% CPU usage for the last 5 hours): I should add that the migration is finished and I can use Photos fine.
I am afraid at what would happen if I decide to delete either one of those libraries. I also wonder what happens if I edit photos in Aperture or Photos. I expect those to be completely separated (duplicated libraries) but apparently it's not the case.
I don't mind HDD usage I have plenty of space.
