MacOs dropping support for Intel-based applications

I was vaguely aware that Tahoe was the last MacOs that would support Intel based processors. However, what I hadn't realised is that in MacOs 28 the Rosetta compatibility layer for Intel based applications will be removed. This means that any applications that aren't compiled for Apple Silicon will no longer work.

I've noticed a couple of apps pop up with a warning about this pointing me at this article. https://support.apple.com/en-gb/102527?cid=mc-ols-rosetta-article_102527-macos_finder-52526201

I'm not sure if this is a big deal or not. I think any vaguely new apps will be fine, but I thought it might be worth posting about it here in case anyone was unaware of this.

Oddly enough one of the apps complaining about this was a little tool I vibe coded for myself a month or two ago. I presume this was just a dependency it was using but it does illustrate that just because something is new does not necessarily mean it won't be affected. (But no, let's not go down the vibe coding rabbit hole in this particular thread.)

I suspect this is ultimately a good thing unless you happen to depend on something that is no longer being updated.
