I am a photographer and I was dumping my cards to a file on my desktop yesterday. Suddenly I started getting notifications that my iCloud is running out of data and I must upgrade. I thought this is pretty strange because I have dropbox and don't care much about iCloud except for my phone backups. So I get into it's settings and I see it's syncing all my desktop files. This is ****ing stupid. I have files with hundreds of GB worth of images or video on my desktop. So I tell it to stop syncing my desktop. Of course now all my desktop files DISAPPEAR. They only remain in dropbox. I have a ****ing 1TB SSD for quick access to my files, I do not want them in the cloud. So I see the fix is to simply copy the files back to the desktop from the iCloud folder. Ok, that fixed it. But WTF was Apple thinking? Obviously I don't want to sync some of the largest files on my Mac, and if it's on my desktop, it's because I want it right there available locally. Because of some syncing issue I had to dump my import as it was in progress and start again. What was most annoying about this is that I had no warning or indication about it. Sure sync my documents folder and keep the drive available to me I guess, but don't start auto-uploading stuff without my knowledge. This is the kind of file management automation that frustrates me about FCPX, (the now defunct) Aperture and iTunes. It's so hard to actually KNOW where something is located. Any other surprises in Sierra that will **** with my workflow?
