I like this and would seriously consider buying it - except that the purchase page only has prices in something called "AA$". I have no idea what currency that refers to (AA is Aruba, but they don't use dollars), or how much that might come to in my local currency.

Must be a placeholder? But you briefly made me think it was some sort of Apple-specific currency. We really aren’t that far away from “Apple Bucks” are we?

Thanks for reporting this! To clarify, what currency did you expect to see?

Reverse engineering is hard! I use Hopper ( https://www.hopperapp.com ) to disassemble related binaries and frameworks. It's a great way to explore whats actually happening within macOS or Apple apps. You can also export assembly files and throw various agents (Gemini, Claude etc) at them to learn more. It's surprisingly effective!

I'm no pro rev. engineer or anything, but did you try alternatives to Hopper at all? I've never had much luck with Hopper compared to Radare2 and IDA.

I haven’t tried those, but Hopper has been working pretty well for me. Although I mostly just sift through the assembly and pseudocode, and don’t use many advanced features.

Hi cindori, I couldn't figure these out without purchasing: 1. Does Backdrop plan to support 5K/6K wallpapers? Those resolutions are pretty standard for Mac workstations. 2. Is functionality similar to TopNotch supported where the notch is hidden? If this was supported I'd likely buy a lifetime license today.

1. Yes, they are technically supported but sourcing material is hard. 2. It does not currently, but I’ll consider adding support for that! Although I feel that it might not work well on macOS Tahoe, which ships with a new ”faded blur” menu bar background.

Apps break on OS updates all the time. I'll do my best to keep supporting this feature. Who knows, maybe Apple will take note and make it a default feature in next macOS?

hoping your business gets eaten alive is a strange wish

To be fair in this case, most would expect this to not be a viable business.

I'm in Australia, you're Swedish (but I don't know if your business is based there), and most web sites show US prices by default. So I wouldn't like to guess whether it was meant to be AUD, USD, or SEK.

Worth mentioning that if you want a free way to do this that does not require running additional software. All you have to do is have a video you want to use, download one of apple's through settings, go to the location of the downloaded background (I don't remember where that is right now but a quick google search would take care of this), rename your file to the name of apple's file and then replace it. Mac will ac…

I think you will find that if you try to do that, it will actually not work properly. Visiting the lock screen repeatedly will eventually crash the wallpaper extension, producing a black screen. And updating macOS will reset all your wallpapers. Backdrop uses a more advanced approach that ensures that it works seamlessly across reboots and macOS updates.

seamlessly across reboots and macOS updates

Famous last words.

Hi Oskar - I'd love to propose a product idea to you, i'd love to buy something like this or the Mac if it were available. I had this on my linux laptop ( https://man.archlinux.org/man/xtrlock.1.en ) but it is surprisingly difficult to find for Macs -- something that locks the computer but still allows you to see the screen. This would be ideal for log windows, dashboards, etc. Separately, if there is something like…

What you're asking for is called "kiosk" mode. Here's a random app I found: https://www.mackiosk.com/

I don't think this is quite the same thing as a kiosk setup, though depending on your specific goals you may find a kiosk-based solution to be an acceptable alternative.
