In this case, the trove in question is Jorvik Software. At last count, there are 23 free and open source apps on the site. They’re created by Jonathan Hollin, a back-end developer on the Isle of Man who builds native macOS in his spare time.

“That’s what this site is about — the things I make for the fun of making them,” he says on his About page.

The one that caught my eye, and drew me into the site, is RainbowApple, a utility that overlays the classic six-colour Apple logo on top of the black one that Apple now ships. Pretty simple, but looks like fun.

Also among the many utilities: CalendarUpcoming to alert you of upcoming events, CopyLens to pull the text from an image, MenuTidy to collapse menu bar icons behind a chevron, WindowPin to pin any window so that it is always on top.

The only one he considers to be a full-blown app is Jorvik Daily News, an RSS reader that lays out the news like a daily newspaper.

On top of that, there are three retro games and four screensavers that look cool.

Eventually some of these will make their way into the thriftmac collection, but don’t wait for me — explore on your own.
