MeepOS

**MeepOS** is a series of operating systems for the Meepgresh computer. It is based on BarOS and Mac OS. This series of systems are different from Un Computer, as the Bikeruna and UNPower series of processors are only made for Meepgresh and each version of MeepOS runs on different hardware, unlike Unbar where every system runs in constantly-evolving hardware. To unlock its releases, one must get enough points.

According to the About box, the MeepOS line of systems was created by **Un Calculators**.

### Boot Menu

The Boot Menu is the menu that appears when the player opens the game. Unlike Un Computer's boot menu in the form of an Dead Star BIOS, Meepgresh's system select screen is in the form of a window with all releases of MeepOS (including those that are not installed and those that are available in future updates, which are grayed out). Tapping one opens that version.

### Menu Bar

The Menu Bar is the main shell of every MeepOS system, which replaces Game Menu from Unbar systems. It has 4 main buttons: the Un button, Game button, Store button and Help button. In the apple menu, you can check information about currently used system, access Flyer and Settings, play Puddle (or open Clock in Meep System 1) and restart the system. In the Game menu, you can load your existing save, start a new game and check Unachievements.

Commands on the Menu Bar can change depending on the currently opened application. The whole Menu Bar looks similar to the taskbar in WP-DOS Shell.

### Flier

Flier is MeepOS' alternative to UnDOS. Unlike UnDOS, Filer works in GUI mode. The application can be used to find Bonus.exe files and a majority of cheats.txt files. Files and directories can be deleted by dragging them on the Recycle bin.

### Settings

Settings is found in the Begin menu in every single MeepOS operating system. In the settings menu, you can change various game options and customize appearance of the currently used system.

### Puddle

Puddle is first unlocked in Meep System 2. It is similar to the sliding puzzle in Unbar Dista and Tallhorn, but instead of a 3x3 grid, it's a 4x4 grid. Also, instead of pictures there will be just numbers. This is because it doesn’t have room for a color photo like in Dista or Tallhorn.

### Looks

There are different looks for Puddle in MeepOS systems.

In Meep System 2 to Meep System 6, the whole puzzle is black and white. In MeepOS 7 to MeepOS 9, the puzzle is coloured. In MeepOS 10, the quality is high and the items are glossy. In MeepOS 10.II, many items are on a brushed metal background with shades. In MeepOS 10.III and onwards, the puzzle takes on a more simplistic look.

### Shutdown Panel

The shutdown panel is used for closing the game and switching to another system. The shutdown panel can be accessed by going to the apple menu and choosing the Restart option. The Restart option will shut down the currently running version of MeepOS, and will then return the user to the Boot Menu. The Shutdown option will play the shutdown sound and then show a black screen with a window that reads "It's now safe to turn off the game". The safe to shutdown screen looks similar to that of Unbar NOT 4.0.

### Un Ambulance

When you get a BSOD, you can use this tool to fix errors in your Un bar by playing a minigame. You have to tap the Scan button. Currently, this is the only utillity in MeepOS.

### Store

Store works the same as it does in Unbar systems. You can spend real life money to purchase upgrades. The minimum buyable upgrade is called "Unbar Ad Free" for USD$1.99, which removes ads, while the maximum buyable upgrade is called "Unbar ∞" for USD$23.99, which removes ads and unlocks all current and future skins.

### Clock

Clock is an application which displays the current time. In Meep System 1, it can be opened by selecting the Clock command in the apple menu. Clock will then appear on bottom-left part of the screen. Starting with Meep System 2, the Clock is on the right part of the Menu Bar.

### Cursor

The Cursor is a graphic showing where the mouse is located. On PC it is activated by default and on Mobile it is optional and intended for external mouses. And this sound is played whenever you click on something:
File:Click.mp3

### Window animations

Since the alpha of the July update (0.8010), the animations of windows in MeepOS prior to MeepOS 10 will show a black outlined rectangle zoom up and show the window. In MeepOS 10 and onward and P@@pmeep, the window will pop up and squeeze a bit, the latter as if were jelly, except for in UN Jams.
### Differences between UnbarOS and MeepOS

* The way to play Unbar is different from **MeepOS**, but they have the same goal: to empty the unbar.
* MeepOS has Filer, which is not in Unbar, but UnDOS is in it.
* Un button, game mode names, Message, Paper, BSOD and more are different than in Unbar systems.
* MeepOS is new, while the first Unbar systems are from the beginning of the game (-12.0).
* The boot menu is different.
* A pair of other buttons including in MeepOS: About, Filer etc.

## Editions

*Main article: Editions*

Currently, Editions work mostly the same as they do in UnbarOSes.

## Trivia

* Un Calculators is based on Pyrus Pyrifolia Calculators. Pyrus Pyrifolia is the scientific name for Asian Pears, that look like an apple.
* The idle cursors in MeepOS 10, 10.II, 10.III, 11, 12 and P@@pmeep are similar to that of the Black Unbar 10X cursor.
* The safe to shutdown screen is different to other systems, alongside Unbar TNT 4.0. However, instead of the night sky window with bat icon, it is a Meepgresh sleeping with Z's on top of him. It looks like the Z's are similar to that of those when Recycle bin is sleeping. In MeepOS 10, 10.II and P@@pmeep, the Z's are moved to the centre of the Meepgresh's screen, have minus signs in between and has a exclamation mark at the end. In MeepOS 10.III, the Z's are gone, and a unMeep 56 with closed eyes replaced the unMeep 46.
