I've just imported about 100Gbs worth of Photos from an SD card into Mac OSX Photos. It took a while but the circle timer seem to finish and when I look in Finder I can see the Photos library has a size of 100Gb but I can't view them anywhere in Photos itself - not Imports or anywhere. I've tried rebooting, rebuilding the library, updating to the latest OS but still can't see them. Can anyone help?
