Around 15% here in Germany. That's more than I expected, but it isn't mainstream. At least not in the sense that people will expect MacOS behaviour by default on their computers, or even to the point where you can expect familiarity with MacOS from most users.
We clearly live in different bubbles because this is the first time I've seen someone refer to MacOS as "very mainstream". iOS, sure, but I haven't seen many Macs out in the wild. It's certainly not common to the point where people would expect MacOS behaviour as the default.
Hamas did not lead any peace talks worth a damn and their "armed resistance" has only ever consisted of attacks on civilians, usually by firing missiles at settlements in unambiguously Israeli territory (attacking military installations or even settlements in the West Bank would've been at least somewhat defensible, but that's not what they've been doing) and then hiding behind their own civilian population to hinder Israeli retaliation, getting them killed in the process. They also did all that from Gaza, an area that Israel de-occupied after the Second Intifada, and which could have served as a positive example of peaceful Palestinian self-government and eventually independence instead of the opposite.
Another issue was that Vista had very steep system requirements, which Microsoft deliberately understated. As a result it ran like shit on a ton of machines despite them technically meeting the requirements.
Die Regierung ist allgemein unbeliebt weil sie einfach seit Jahren nichts zu Stande bringt außer Streit. Liegt nicht wirklich an den Grünen und nicht Mal and der SPD, aber ist in der öffentlichen Wahrnehmung halt ein Fall von "mit gefangen, mit gehangen".
I don't think you can lump Endeavour and Garuda together. Yes, they're both based on Arch but Endeavours basically is Arch with a GUI installer and sane defaults while Garuda changes a ton of things and adds a ton of customisations that make it very different from a plain Arch (or Endeavour) system.
No need for anything particularly modern. Even on a ten year old laptop I've not noticed a difference (Windows, on the other hand, barely runs at all on that machine).
My issue isn't that it's breaking sites. It's the fingerprint resistance making the basic user experience unpleasant. Refusing to remember window size, forcing light mode, etc. I understand why, but those aren't sacrifices I'm willing to make.
Firefox. Librewolf's defaults make it very inconvenient to use as a normal, day to day web browser. You can obviously change all of that but at that point you might as well just use Firefox with a handful of add-ons so that's what I'm doing.
As claimed by MediaTek. I doubt they're outright lying but I can guarantee you that the "up to" is doing a lot of heavy lifting.
