Mac OS 9

Mac OS 9 is the last version of the original Mac OS operating system for Macintosh computers from Apple. Only Macs with PowerPC processor support (ie, neither the old nor the 68K current Intel -based Macs ). Mac OS 9.0 was released on 23 October 1999, and the last update to version 9.2.2 was released on 5 December 2001.

Mac OS 9 was called " Mac OS 8.7 " before its release in development versions, and in fact are the changes that Apple undertook in half version step by 8.1 by 8.5, larger than those of 8.6 after 9 The jump in version number is also be justified by the fact that Apple for Mac OS X is the next generation operating system that would go near 10. In order to promote the sale, Apple introduced the first free iTools (later. Mac, then MobileMe, and finally iCloud ), which included mainly a free e- mail account, but put Mac OS 9 for registration ahead.

The most important new features of Mac OS 9 were multi-user support and keychain function, with a central repository was introduced for passwords.

The versions from 9.0.4 was downloaded from Mac OS X in the Classic environment to use older programs that will not run under Mac OS X, can. The Classic environment is no longer supported on the Intel processors used today by Apple. Alternatively, the emulator SheepShaver is recommended.

After the first version of the successor of Mac OS X had already appeared in 2000, Apple CEO Steve Jobs announced in May 2002, the development of Mac OS 9 will no longer continue. In January 2003, the first Power Mac was sold, no longer able to boot Mac OS 9, the last OS 9- bootable Macs were sold in the summer of 2004. The version of Mac OS 9 programs in the Classic environment is still possible on all PowerPC Macs imported from 2006 Macintosh computers with Intel processors Mac OS 9 programs are no longer supported. In addition, the Classic environment is running Mac OS X v10.5 (Leopard ), which appeared in October 2007, removed from the system. With this move, Apple Mac OS 9 would be a thing of the past. Running Mac OS 9 programs is thus on PowerPC Macs with Mac OS X 10.5 no longer possible ( without software such as SheepShaver ).
