Hi all, I have old external hard drives full of photos and decided to upload them all on iCloud. I'm using a MacBook Air that is short of hard disk space. Here is my issue: If I'm not mistaken there is no way to use Apple's Photo App to upload photos directly from my external hard drive to the cloud – all photos need to be saved on the local hard drive first. But there is no way I can do that. So I tried uploading them using Apple's iCloud website. Not just that it's super slow (annoying but acceptable) but it's always that the upload stops after a few hundred photos (website is gone, some error – this happens both with Chrome and Safari). So I was wondering if there is any smoother way to approach this? I was thinking some kind of upload client app for Mac but didn't find anything so far...?
