Thank you! You absolutely get it! +100. I agree, Apple does have choices here. There's a really great text called 'About Face: The Essentials of Interaction Design'. Worth borrowing from a library sometime if you haven't come across it before. It covers the good and ugly of interfaces exactly as the example you describe. Have a great weekend, friend! --- Post Merged, Feb 3, 2017 --- So my comment on this is that it's an awkward message, although it seems to be presumably an essential message for device/disk safety. There have been improvements though, in more recent versions of MacOS, this is now a notification, below. The notification reads better, isn't as intrusive and uses the button wording "Close" which makes more sense. I do suppose it is important to eject disks properly, BUT, ideally the operating system should be ready at anytime to handle the user removing any "disks" and for it to result in no damage to device or disk. That's where we want to head with the user experience. A lot of the thinking behind some user interactions and experiences are carryovers from the pioneering but outdated methods from the past. --- Post Merged, Feb 3, 2017 --- That's interesting. I was under the assumption that all purchased software could be re downloaded anytime from the purchased list in iTunes or in the App Store.
