The first and foremost thing for me is aesthetics. I love being able to customize all of the colors and blur effects and button layout. Additionally, I like the gesture support within the UI. Lastly, I love how it integrates with Last.fm so all of my scrobbles are synced up without needing to scan.
I would not consider it a must have, but it makes so many quality of life improvements for apple music listeners.
My family’s home computer was a MacMini (running Mavericks). As a high schooler at the time, I loved the simplicity of navigation and creation. My first smartphone was an iPhone 5s.
I stuck with them for my undergrad because I didn’t know otherwise. Windows felt like a downgrade at the time and gnu+linux or bsd were not on my radar.
I loved the hardware. I loved the integration between my mac and my phone. I learned to use the command line and make my mac incredibly powerful and fast. Its the hardware and software I used throughout my undergraduate and graduate programs and I continue to use it in my career in the museum field.
I now hop back and forth between macOS and FreeBSD, but it’s all on Apple hardware.
