Ouch. I hope it's a bug and not your video card becoming unsupported. I dread the day that happens here if it's earlier than Apple releases another model or two to give me a choice in new computers. As it is, I got the message from Nvidia to upgrade my driver, did so, and now every launch I get the same screen saying I'm to update—but also saying no newer driver is available. If I didn't love what I can do with computers, I'd hate them.<G>

Hey Cristen, i tracked it down to an issue with the GPU. When active, i get those nasty edges, but once i deactivate the pref, the issue goes away.

Tang, this issue isn't about the magic wand or quick select, i'm pointing out a problem with the Select Subject tool in the options bar.

Using the majic wand tool, not the quick selection, you will see on the options bar to set tolerance...

There are no tolerances for Select Subject. So I'm not sure what TangCanada is referring to.

That said — I'm not seeing aliasing in the Release version. Granted, it still isn't terrific, but it's not aliased like that. I do still need to go into S&M to torture myself with refining the edges, but I'm most certainly not starting out at that horrible a level. I'd upload a JPEG screenshot, but the site says it can't process it. It's only 25KB at ~600x600 pixels. Hey ho. Just take my word for it. <g> It's not aliased, even at 200 percent.

See menu options at top ... tolerance is set too low.

A workaround could be to use >Select >modify >smooth - before masking or deleting background.

We're not able to reproduce that in-house on 19.1.4 or older released builds.
I noticed you're in the Prerelease program.
Is there a chance you've launched an experimental build?Thanks,Meredith
