Depends on what you need on the Mac. For many common image editing tasks like rotating, cropping, resizing, saving in a different image format, some simple levels, exposure, saturation, sharpening and white balance adjustments as well as a few mark up tools (adding text, arrows, various shapes) Preview is perfectly adequate. That’s probably more than enough for people who don’t actually create any images. Maybe the photo editing is a bit anaemic, but Photoshop’s photo editing tools are cryptic and hard to use for occasional users and those probably benefit a lot more from a simple editing panel with a few relevant sliders than from all the hard to unlock power of Photoshop. The only notable absent thing is some sort of image straightening tool (only 90° rotations are possible). If you want to do actual image editing there are a couple of excellent apps, namely Acorn and Pixelmator, both modern and frequently updated. You have to pay for them but that’s Mac software. You should have to pay for them. That’s only proper.
