Not enough disk space so I can't download high res photos from iCloud
Photos Library: When attempting to switch from Optimize Mac Storage to Download all Originals to this Mac, I keep getting the error that I don't have enough storage so the download fails to start... I thought I had plenty of storage. The About this Mac | Storage tab said I had plenty of storage, but a substantial amount was "Purgable". However, when I used Disk Utility, it said I had a lot less free storage. No matter how many files I deleted to make room for downloading my photos from iCloud, the Disk Utility's amount of free storage would not increase.
