==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<ref>{{cite journal |journal=Washington Apple Pi Journal |date=October 1988 |page=70 |title=THE SOFTWARE MAC PEOPLE PREFER |author-last=Pecora |author-first=Louis C. |volume=10 |url=https://www.wap.org/journal/showcase/washingtonapplepijournal1988v10no10oct88.pdf |publisher=Washington Apple Pi, Ltd. |access-date=2017-09-08}}</ref><ref>{{cite web |title=Disk repair utilities: a special report |website=[[CNET]] |date=2009-09-02 |url=https://www.cnet.com/news/bdisk-repair-utilities-a-special-reportbr/ |access-date=2017-09-08}}</ref> and includes utilities for data recovery, disk partitioning, disk defragmentation, and floppy disk duplication, among others.<ref name="infoworld_1990-01-29">{{cite magazine |magazine=[[InfoWorld]] |page=81 |date=1990-01-29 |title=The Top 100 |publisher=[[IDG]] |volume=12 |issue=5}}</ref> 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.<ref>{{cite web |title=SUM II NUM 2.0 |date=1992-04-27 |author-last=Anbinder |author-first=Mark H. |publisher=[[TidBITS]] |url=https://tidbits.com/article/3111 |access-date=2017-09-08}}</ref>

SUM v1.1 was published in 1988 and requires a [[Macintosh 512Ke|Mac 512Ke]] or later system. This version also has limited support for [[Macintosh File System|MFS]]-formatted floppy disks.<ref>{{cite web |url=http://www.vintagemacworld.com/hd20.html |title=Notes on the Hard Disk 20 (HD20) |work=vintagemacworld.com |author-last=Beesley |author-first=Phil |date=2008-06-23 |access-date=2017-09-08 |url-status=dead |archive-url=https://web.archive.org/web/20071211091026/http://www.vintagemacworld.com/hd20.html |archive-date=2007-12-11}}</ref>

SUM II was announced for release in August 1989<ref>{{cite magazine |magazine=[[Computerworld]] |date=1989-08-21 |page=41 |author-last=Pastore |author-first=Richard |title=Appetizers at Macworld |volume=XXIII |issue=34 |publisher=[[IDG]]}}</ref><ref>{{cite book |title=Sum II - Symantic utilities for Macintosh - crashed disk and file recovery, backup, optimization, and security. |author=Symantic Corporation |date=1989 |location=Cupertino, CA, USA |oclc=29611295|author-link=Symantec Corporation }}</ref> and includes tools for data backup and data encryption.<ref name="infoworld_1990-01-29"/> 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.<ref>{{cite magazine |magazine=[[Family Computing|Home Office Computing]] |date=September 1991 |title=Symantec Utilities for Macintosh - Sum Ii - Software Review |url=http://findarticles.com/p/articles/mi_m1563/is_n9_v9/ai_11203273 |author=Freedom Technology Media Group |publisher=[[CNET|CNET Networks, Inc.]] |access-date=2017-09-08 |archive-url=https://web.archive.org/web/20071120011408/http://findarticles.com/p/articles/mi_m1563/is_n9_v9/ai_11203273 |archive-date=2007-11-20}}</ref> In September 1991, version 2.1 of SUM II, which would support System 7, was announced.<ref>{{cite magazine |magazine=[[InfoWorld]] |page=16 |date=1991-09-30 |title=SOFTWARE: PIPELINE |publisher=[[IDG]] |volume=13 |issue=39}}</ref>
