adds support of G5 model Macintosh released before December 2004, 1.25 GHz eMac, and various Mac G4 notebooks. However, some tools may present errors when running Mac OS X 10.4 (Tiger). End of life In 2004, Symantec confirmed it had stopped developing Norton Utilities for Macintosh and Norton SystemWorks for Macintosh, and concentrated its efforts solely on Internet security products for the Mac. Symantec Utilities for Macintosh Symantec Utilities for Macintosh (SUM) is a set of system utilities from Symantec, developed before Symantec had acquired Peter Norton Computing. SUM started out as a revised version of the MacZap data recovery tools and includes utilities for data recovery, disk partitioning, disk defragmentation, and floppy disk duplication, among others. Later SUM tools may have shared code with Norton Utilities for Macintosh. Some of the functionality from SUM II was incorporated into Norton Utilities 2.0. SUM v1.1 was published in 1988 and requires a Mac 512Ke or later system. This version also has limited support for MFS-formatted floppy disks. SUM II was announced for release in August 1989 and includes tools for data backup and data encryption. SUM II v2.0 runs on Macs with System 4.2 or higher and 1 MB of memory. One review mentioned that it is easy to make use of most of SUM II's utilities, but at the same time, the file recovery functionality in SUM II is less automated and required more manual configuration compared to the file recovery functionality in Norton Utilities. In September 1991, version 2.1 of SUM II, which would support System 7, was announced. Norton Utilities for Unix In 1990, Segue Software developed a Unix version of Norton Utilities, in cooperation with Peter Norton Computing and INTERACTIVE Systems Corp. Interactive Systems stopped marketing the software in 1992. In February 1994, AlmondSeed Software, Inc. licensed the software and released it as "The Almond Utilities for UNIX". AlmondSeed Software released the Utilities for SCO UNIX and Sun Solaris. Historical competitors Central Point PC Tools and MacTools McAfee Nuts & Bolts Reviews BYTE in 1989 listed Norton Utilities 4.5 for DOS as among the "Distinction" winners of the BYTE Awards, stating that it was "an essential first-aid kit". Darian Graham-Smith of PC Pro gave Norton Utilities 14 an overall rating of 2 of 6 stars. He concluded “There's simply no good reason to pay this much for such a flimsy collection of tools.” PC World reviewed Norton
