BarOS (Bar System from 1 to 6/before 1991) is a series of operating systems for the Progresh computer (later named pBar starting from 1999) that was created by Pyrus Pyrifolia Calculators in 1983. It is based on Apple's macOS lineup of operating systems (previously known as Mac OS X, then OS X) and its predecessor, Classic Mac OS. Introduced in 0.6450, BarOS is different from Progress Computer, as the Bikerola and PBPower series of processors are only made for Progresh computers and each version of BarOS runs on different hardware, unlike Progressbar where every system runs in constantly-evolving hardware. To unlock new releases, one must get enough points.
To unlock this system, you must unlock Progressbar 10.
