When last I left Mac OS to go back to Windows machines for my day-to-day work, I lamented leaving the easy integration of Image files behind. I guess I was running Win98SE at the time?
Anyhow, fast forward to today and going from Win10 to High Sierra was the exact same feel. Scrolling through usefully-magnified image files in a folder just doesn't happen in Mac OS...well, I'm sure there's a way to do it, but I haven't figured out the right combination of Shift-Command-Clicks. Ironically, I didn't need to seek any tutorials in Windows to learn to "Open" -> "Scroll Arrow".
