I think the last power loss here was 8mo15d ago at my place (around Christmas time in 2024?), but it could easily result in a data loss if you're using an external SSD through a dock, because your MacBook lacks a sufficient port supply, and because internal storage is severely limited by Apple, too, so, you may as well be required to use it with an external SSD at all times.

4k@27in may be too small pitch, but QHD@27in would be too pixelated. Especially on macOS that does NOT allow turning off antialiasing.

I'm currently using the 400nit HP Z24m G3 @ 2560x1440 @ 24in with my 16GB MBA M1, the colours are absolutely amazing compared to the cheaper Lenovo monitors.

Firefox works great, because it lets you turn off antialiasing, but there's no way to turn it off in Brave or Chrome, which results in super washed out and blurry text everywhere.

Honestly, macOS is not production ready at this point. Data loss because you have to use an external SSD through a dock, poor monitor support with regressions after moving to Apple Silicon, no ports for anything, inadequate RAM/storage that cannot be upgraded in any way besides the external SSD through a dock with a UPS.

Basically, the most simple things are super complicated.

Didn't it used to be the opposite with the Macs, where they were actually simpler and more flexible?
