Mac OS X je zasnovan na UNIX-u. zbog čega ga odlikuje vrhunska stabilnost. Većina kompanija, vladinih ustanova i fakulteta oslanjaju se na UNIX za svoje kritične aplikacije.
Operativni sistem OS X , ili popularni Tiger, jedan je od najsavršenijih operativnih sistema na svijetu. Od samog početka je radjen da bi bio podešen za dvoprocesorske Macove. Sa takozvanim Preemptive multitaskingom OS X je u stanju da odredi prioritete kod trenutno aktivnih aplikacija i tako im rasporedi onoliko procesorske snage koliko im je potrebno. OS X ima integrisan i X Window System, popularno nazvan X11, koji korisnicima Unixa omogućava pokretanje X11 aplikacija paralelno sa OS X aplikacijama. Pomoću Randezvous aplikacije integrisane u OS X, korisnik može jednostavno i brzo napraviti računarsku mrežu i povezati se sa drugim korisnicima.
Kod OS X memorija je potpuno zaštićena, a aplikacije ne dolaze u konflikt s OS-om ili jedna s drugom.

u potpunosti se slazem..

From the report: 'The resultant file decompresses into what appears to be a standard JPEG icon in Mac OS X but was actually a compiled Unix executable in disguise. An initial disassembly reveals evidence that the application is a virus or was designed to give that impression.' The virus is said to also spread via Bon Jour instant messaging."

Virus attacking Apple Macintosh PCs found: experts

Thu Feb 16, 9:07 PM ET

http://news.yahoo.com/s/nm/20060217/tc_ ... e_virus_dc

A malicious computer worm has been found that targets Apple Computer Inc.'s (Nasdaq:AAPL - news) Mac OS X operating system, believed to be the first such virus aimed specifically at the Mac platform.

The worm is called OSX/Leap-A, according to a posting on the Web site of antivirus software company Sophos, which said the worm is spread via instant messaging programs.

The worm attempts to spread via Apple's iChat instant messaging program, which is compatible with America Online's popular AIM instant messaging program, according to the Sophos Web site.

The worm sends itself to available contacts on the infected users' buddy list in a file called "latestpics.tgz," according to the Sophos Web site.

The vast majority of malicious hacks are aimed at Microsoft Corp.'s (Nasdaq:MSFT - news) Windows operating system and some of its products, largely because Microsoft has more than 90 percent of the market for computer operating systems.

"This first Macintosh OS X threat is an example of the continuing spread of malicious code on to other platforms," said Vincent Weafer, senior director at Symantec Security Response, in a statement.

The worm will not automatically infect Mac computers, but will ask users to accept the file, Weafer said.

Symantec ranked the new worm as a Level 1 threat (with 5 being the most severe).

An Apple spokesperson was not immediately available to comment.

Apple played down the threat.
"Leap-A is not a virus, it is malicious software that requires a user to download the application and execute the resulting file," said an Apple spokesperson.
"Apple always advises Macintosh users to only accept files from vendors and Web sites that they know and trust," said the spokesperson. "We have a guide to safely handling files received from the Internet."
McAfee Inc. (MFE) rated the virus at "low-profiled" on its security Web site, citing media attention to the threat.
Symantec Corp. (SYMC) also issued a notice about the worm, saying it is a low-level threat.

Isto kao na PC-u...

U samom početku je bio isti fazon, pa su svi klikali NO...pa kad su skužili da "savjesni" kompjuteraši klikaju NO, upade su konstruisali tako da se dešavaju i kada klikneš NO...

Nakon toga su obradili i X za terminate program, tako da stvar upada i na taj način...

Safari struck by Zip security warning

By Macworld staff

A new security vulnerability in Safari has been identified by security experts at Secunia.

The company - which rates the flaw as “extremely critical” - says that the vulnerability was discovered by a source outside the company, Michael Lehn.

It can be exploited by malicious people to compromise a user's system, it warns.

The vulnerability is caused due by an error in the processing of file association meta data (stored in the "__MACOSX" folder) in ZIP archives.

“This can be exploited to trick users into executing a malicious shell script renamed to a safe file extension stored in a ZIP archive,” Secunia warns.

It can also be exploited automatically by Safari when visiting a malicious website.

The company has released a test users can run to check if their systems have been affected.

The vulnerability has been confirmed on an up-to-date system running Safari 2.0.3 (417.

and Mac OS X 10.4.5.

Users can mitigate the threat by disabling the "Open safe files after downloading" option in Safari.

Isti sam ti takav

Tek sada vidjeh temu i ucini mi se da ce se pricati normalno, a ono PC bolji, jok Mac bolji. Provincija, pa to ti je.

Ja u kuci imam samo OS X 10.4, a na poslu radim samo i iskljucivo sa PC-em. Mac sam kupio zato sto sam mislio da cu moci zaraditi praveci aplikacije za Mac, na zalost, nema od toga nista. Trziste je premaleno i aplikacije za Mac su tako usko specijalizovane, da nema stvarno svrhe raditi nesto za Mac. Uz to sam imao nevjerovatnih problema praviti za Mac, jer za razliku od Microsoft svijeta, APPLE boli lijevo m*do za nekog tamo Ulicara koji pravi aplikacije za OS X (u doba kada nije bilo vise od dvadeset aplikacija za novi OS X). Kada je firma za koju sam tada radio negdje u isto vrijeme kontaktirala Microsoft da nam pomogne sa .NET frameworkom, njihovi ljudi su dosli kod nas, donijeli knjiga, alata, nema cega nisu, samo da bi nam pomogli da radimo aplikacije za tada jos uvijek super novi (Beta 2) .NET framework.

U isto vrijeme kada sam ja licno zatrazio od Apple-a da poprave BUG u svom kodu, oni posalju e-mail da odj*bemo, samo ne u toliko rijeci. Jedno godinu dana kasnije, kada su vidjeli da se aplikacija za windoze platformu prodala u 100,000 (da, sto hiljada) primjeraka, na tri kontinenta, a sve to u obrazovnom polju, koji je bio uvijek Apple uzdanica, sto je prouzrokovalo da nekoliko hiljada ljudi predje sa Mac-a, na windoze, oni su poceli da salju e-maile, prvo molbe, a onda i suptilne prijetnje ("vi necete da napravite verziju 2, a distribuirate dot update za OS 9 na svom CD-u, a mi mislimo da vi nemate dozvolu", a imali smo i nas im je advokat rekao da od*ebu u skokovima, ili cemo ih vidjeti na sudu), da bi na kraju pitali "koliko para treba da vam damo da napravite aplikaciju"? Kada smo im rekli $3.2 milliona, prestali su da nas peglaju.

Neise, volim Mac, ali nisam Mac majmun. Nisam od onih koji ce prijetiti ljudima ako kazes nesto protiv Mac-a. Nisam ni jedan od onih koji ce prijetiti ako kazes nesto protiv windoza. Mac je super, bez windows kutija, mi bi bili dvadeset godina unazadjeni. Sve je danas, za obicnog korisnika, stvar bukvalno sexualnih preferenci. Ukoliko hoces da budes "metrosexualac", onda koristis Mac, jer je "bolji". Ukoliko si jedan od onih "drljatora", onda koristis windoze, jer imaju "90% vise stvari nego mac". Meni su sve trebe dobre, zato koristim i jedan i drugi
