spent hours creating an album of photos on my mac running high sierra. opened Picaboo app and clicked on "from my computer" nothing happened. safe mode is not on, tried chrome instead of safari, tried putting photo app photos into a folder on desktop and dragging them in... nothing works. customer service guy claims there is a problem with my photos app. and there is nothing he can do.Never had problems with photo app with other third party apps. Now I have Lost my money for a voucher! it hasn't expired, but picaboo does not work with Mac/High Sierra. Or the service rep is ignorant.be warned!
