Do you mean you're surprised I could enjoy playing ESO on a MacBook rather than on a Windows PC, or that I could enjoy switching back to a Windows PC after having experienced a MacBook?

The first time I tried to play ESO on my MacBook Air, the graphics were all messed up, as though my character were being rendered inside out; it was like there were vectors going out from my character to the edges of the screen, and the planes they created were filled in with colors. I don't know how else to describe it, but basically I couldn't see anything well enough to navigate through the environment, and if I did manage to move around then the picture would often go into an endless spin as though my character were twirling. Disappointed, I gave up trying to play it.
Sometime much later, I was going to be taking care of a friend's house while she was on vacation, and I wanted to see if I could at least use my MacBook Air to sign on and grab my daily login rewards while I was at her house. Lo and behold, the graphics rendering issues were gone!
I should point out that after I bought my MacBook Air, I'd tried to update it to the latest version of macOS, which at that time was Mojave, but it simply would not download and install the update no matter how often I tried doing so through the App Store. I later decided to search for instructions on how to update to Mojave, and following those instructions I was finally able to do it. This was between the time I'd first tried unsuccessfully to play ESO and the time I discovered it was suddenly working, so I figure my original problems were caused by a lack of compatibility between whatever pre-Mojave macOS version was on my MacBook and the then-latest build of ESO for macOS.
However, then I started having problems related to the mouse pointer, where an extra copy of the pointer would get stuck on the game screen in the most annoying places.
Also, there were problems with the borders of the window, where I'd move the mouse pointer to do something and suddenly find that somehow I must have clicked on the desktop outside the borders of the game window and caused the game to lose focus.
And the majority of the time I couldn't get the game to close down normally, regardless of whether I tried to quit from inside the game (that is, while logged in on one of my characters), or logged out to the character screen and then tried to quit, or logged all the way out to the server selection screen and then tried to quit. Sometimes I could use the keyboard to force quit, but sometimes even that would just freeze up the MacBook and I'd have to shut it down with the power button.
I checked the ESO Forums for any information about these issues, and saw a post from a ZOS employee who said to go into the Mac's Settings and increase the mouse pointer size just a tad, so I did that and it solved the problem of the extra copy of the mouse pointer.
And I took to playing the game in fullscreen mode to avoid the problem of the game losing focus if I inadvertently clicked on the itty bitty sliver of the desktop that was apparently present just outside the game's window (even though no such itty bitty sliver of desktop could be seen).
Then there were updates to ESO when a DLC or new chapter was released, and sometimes after applying an update I would log in, but as soon as my character loaded the screen would start spinning like crazy. It turned out there was a popup dialog box from the system asking if I wanted to let the application change my settings, or something of that nature, but I couldn't see it because it was behind the game screen. After I told the system that I wanted to allow ESO to make changes, the spinning stopped.
Then I decided to go back to playing ESO in a window, so I could see the battery indicator at the top of the screen. This was after numerous occasions of having the MacBook go to sleep because of low battery power while I was in the middle of doing something, even though I never saw the little warning appear in the bottom right corner saying that I had only X number of minutes of battery power left. After I switched back to windowed mode, I was pleased to discover that the issues of accidentally clicking outside the left or right border of the window were gone.
Unfortunately, the problems of the game not quitting properly never did get resolved, so whenever I play ESO on the MacBook it's still necessary to force quit about 90% of the time.
