The scavenger “Trash” worked like tobogan of sweepings, everything disappeared after to reinitiate the computer, could not be worked at the same time in two applications, only in one, since the virtual memory did not exist.

In System 1 it was impossible to create to folder within another folder, in fact all the archives were kept in the same direction of the disc, a note in the table of archives was created so that each file was in its respective one folder and thus the Finder could seem because the file was in his folder.

1985: System 2

System 2 was remarkable in improvements. A twenty percent faster speed of the Finder along with several other options such as: to create new folders, to extinguish, the printer and the items were listed of vertical form with a small icon. The discs or units could be dragged to the sweepings icon and could be extracted.

System 7 was the great change of software this time, it eliminated the Finder and the multiple Finder as it already had the multiple Finder allowing making many tasks simultaneously.  The memory also had a great change to 32b.

The Networking by Apple Talk and to share archives by AppleShare was added to the operating system, like additional option. Software QuickTime multimedia also was worked in this system, but this was been made available like an extra software. System 7 added many characteristics that were going to be constructed in the new system Mac OS X.

1997: Mac OS 8

Mac OS 8 included another renovation to the Finder that could make more things at the same time, giving the option to control manifolds at the same time applications with a better performance of the computers with processor.

The appearance of the Finder was renewed so that 3D had a better aspect, also could be customized. The Web Sharing allowed the user to provide with accommodating pages in its computers.

Software Update allowed the users to have the updates of software outside Internet, and could inform to the users of the new updates when they left.

Mac OS X

This based strongly on the PowerPC-port de OpenStep. For that reason Mac OS X inherits the memory and processor of Mach’s and driver of the device of the interface, BSD’s POSIX – UNIX Protocol of the program that it supports and it works in interface of networks, also having in some elements of the interface of NeXT’s.

Nowadays Mac OS X is the operating system which is virtually present in all the Mac’s, and was worked by one decade to be able to achieve the successful that it is now.
