It’s not that bad. I’ve been using 3 Pro for some time now and I’m quite happy with how it works. Best paired with Opus and Codex, like most models, but it’s solid as a full-stack buddy.
Guess MacOS gives you pass for early-access stuff, right? /s
From a developer's perspective it makes sense, though. You can test experimental stuff where configurations are almost the same in terms of OS and underlying hardware, so no weird, edge-case bugs at this stage.
