The first time using it about 10 years ago was confusing:
Single button mouse --> no instructions, can't find out how to right click
Double click on window --> fullscreen; uh... move mouse around edges to find how to get back to other windows
Drag window to side of the screen to split window --> nothing; search the application menu --> nothing; Cmd+Right? --> nothing; oook, I have to actually resize everything manually
Try to install software from app store:
- you must login --> failed (server was down that day) - search "how to install XYZ on mac" --> download .dmg and follow these steps
"Natural scrolling" still confuses me everytime I touch one even after a whole week it didn't feel "natural". Especially diagonal scrolls felt off; does moving your 2 fingers right scroll left or right?
I remember trying to help out a friend download music on her iphone to play it there. We finally had to download it on the mac, import it into itunes and sync the iphone with it. No idea if things are better.
More recently, video calling was quite the experience. The browser couldn't access the camera, so a popup came up and I had to restart the browser. Then I wanted to share my screen, another popup came up follow by another restart. Finally, I wanted to share audio from a short clip being played, well that isn't in mac so some trial version of something had to be downloaded and I never actually got it to work.
