This is cool - but…

It’s an app, not a system-integrated[1] screensaver?

> Installation

> Drag FakeDOS.app into /Applications.

> Double-click to launch. It installs itself as a menu-bar icon.

> Click the menu-bar icon to configure or start manually.

> After the configured idle time (default: 5 min), FakeDOS takes over fullscreen.

> Type EXIT to return to your real desktop.

> Cmd + , opens six pages of pure control: idle time, warp speed, the ghost writer, sound and more. The PC speaker can be silenced. Your co-workers cannot.

If they had made it as a website, anybody could use it.

I'm surprised that the LLM that was used to vibecode this didn't point it out

Maybe I'm blind, but is this closed source?

Yup. OP wants you to download a sketchy closed source screensaver from an obnoxiously vibecoded website that looks identical to the scourge of phishing pages currently going after random open source projects in a fully automated way.

What exactly is this? Site doesn't work for me (ERR_SSL_PROTOCOL_ERROR). Gathering from the other comments, some screensaver that shows a DOS prompt?

Kinda worse. Some Mac application that acts as a screensaver and shows a DOS-prompt when idle...

Either way, I like the idea of getting people to install and configure fun apps which then know exactly when a PC is not in use.

Could be a useful swarm of devices...

Way back I hacked together a VB6 application (don't remember what it did) but after a while it popped up a new window that faked a DOS prompt formatting the c drive. Then I send it to my best bud on April 1st with a message "Hey, check out this new program I made!" :-)

There is also something about this being Mac-only that feels really dumb or really fitting, I can't quite put my finger on it.

The delicious irony is that it's written for a platform that never ran MS-DOS.

Anyone else append something like this to AUTOEXEC.BAT as a kid at school? We were a right bunch of bastards.

  @echo off
  echo FORMAT /Q C:
  echo ALL FILES REMOVED 
  SET DIRCMD=0

I think a lot about my poor teachers and this Calvin quote comes to mind.

This would be more trustworthy (and portable) as a website (Would have maybe also needed less tokens to produce)

Instead it's a somewhat sketchy app that by design happens to know exactly when my PC is not in use...

You couldn’t run a format command when within the disk you were trying to format. You’d need to (for example) cd A: and then format c:.

Deltree, on the other hand…

It amusing how Mac users yearn for the PC experience. They know they're missing out on something great, but they can't or won't leave their cult.

Except dos isn't the PC experience. It was back in the 90s when you'd edit your config.sys and autoexec.bat to shift your himem settings so you could run a given game with your soundblaster

That world doesn't exist any more, whether you're on a mac, linux, or any other OS.
