I don't think Siracusa is berating Apple for removing PowerPC support, he's just giving a case where he ran into this particular issue. In fact, he's willing to give Apple the benefit of the doubt. Honestly, for what it sounds like Siracusa uses Photoshop for, he should just use Acorn. http://flyingmeat.com/acorn/
I might post the Acorn files this weekend to let someone else remove the slide and release layer. I like it, though. I find it adds a bit of pleasant uniformity to them.
Acorn 4 is a lovely piece of software. I'm not on Yosemite and won't be anytime soon, so I can't try this new version...but I urge folks to try it out (or an old version). It's really very similar to Photoshop 7.
Try Acorn It's cheap, and very good. I think there's a trial version to test if they can open your .psd files. They say they can, but may have trouble with complicated photoshop layers.
I approved it for r/apple as well, however help questions don't do so well.
If you're looking for a clone of ~~Paintbrush~~ Paint in Mac OS X, give Paintbrush a try. :)
If you're looking for a photoshop-like product and you can handle quirks associated with the GNU to Mac OS port, the Mac OS X version of The Gimp is good. I personally use Acorn ($50) and it's exceptional — buy it on the App Store.
Take a look at Acorn, which might be a little heavy for some things, but it's quite easy to use. It's my go-to for simple annotation of screenshots, for example.
Also, it's from a company called Flying Meat, so what's not to like? $30.
Acorn is as close to Photoshop as it gets.
Without all the bloat. layers, masks, filters, the Pen tool. The interface is almost the same, too.
Plus it has great tutorials.
I use Acorn.
It's much more powerful than MS Paint, more of a competitor to Pixelmator and a lot of Photoshop's features.
But if you need to make it look crappy (like doing a Polandball where antialiasing is frowned upon) I think you could do it.
On a Mac I use the built-in screen shot tools (⌘ - shift - 3 for a whole screen or ⌘ - shift - 4 for a selection reticle or hit the space bar to select an entire window, including alpha drop shadow). (the history behind that keyboard shortcut is kind of interesting too)
If I want to paint out some identifying information I will usually use Acorn (sort of like Photoshop or Pixelmator) because I own it. But you could use the built-in Preview app.
They get saved to the Mac desktop but I have an Automator folder action that moves them all into a "Screenshot" folder. Then just drag 'em into Imgur.
Acorn is a very nice, very cheap Photoshop alternative. No idea about tablet support, but it's much better at pixel graphics than Pixelmator (which, for example, can't show two windows for the same document at different zoom levels). No animation support, unfortunately.
haha this was hard to find. Here is the link to the Acorn software website and a review
I use three programs when building graphics.
In that order.
If a designer gives me a PSD file to build out, I'll be opening it in Fireworks. Fireworks was designed with the web in mind, everything about how it organizes graphics and handles layout is built with the idea that your final result will be turned into a webpage. Photoshop was never intended for what it is used for.
