I'm using it for the first time ever and can't believe how awful it is. My linux machine broke so I'm attempting to use macos - nightmare! Homebrew can't install gthumb (a simple image viewer), but macport claimed it can. It seems to be downloading and building all the worlds software just to deliver a simple image viewer (as macos has no decent image viewers). Aaargh! I bet it doesn't work even if it ever completes. Update : a few hours later it's still messing around building god knows what - insane! Who built this crazy product? Apparently it's danegerous to abort but this look sset to go on all night just to install "gthumb"! It gave no warning and has no progress indicator, A full new install of linux is far far faster. Sod macos - I'll buy a new linux box.
