Murasaki [1] is the most performant and sleek ebook reader you can get for MacOS currently. It's magnificent, but the creator has regionally limited who can get it, unfortunately.
Less surprising but still annoying is how many hoops you need to jump through to get a good reading experience for manga, particularly on macOS. I had to try many options that were either too buggy, too difficult to install correctly, various aggressive paywalls, or straight up don’t function with high quality scans.
Eventually I landed on one(will edit the name in when I have access to my laptop) that functions well but has some memory issues in importing books, possibly a memory leak.
Maybe I’ve just become shit at finding apps in the modern unsearchable age, but it really feels like reading of all types has diminished enough that we are an unserviceable market.
Linux desktop. MacOS laptop. Android tablets. Android phones.
Where-ever I am, I can pick up a device and continue reading from where I left off. I have the same config everywhere (it would be nice to be able to distribute that) for gestures and taps. I use the same font everywhere (TeX Gyre Pagella, which is a Palatino clone.)
Customization begets comfort.
I always have a phone, a laptop, a tablet or a desktop to hand. The tablet is a great device for reading comics as well as books. The phone is a terrible device for reasing comics, but fine for books.
