Best practive / guidelines for mac / uuid / wwpn / wwnn pools

Is there any best practices or guidelines or suggestions for setting up mac pools, uuid pools, wwpn and wwnn pools in UCS. I don't want to just randomly assign some numbers to these and have to redo them later down the line so I guess I'd like to get some other users experience / suggestions on setting these up?

There's no best practice guide. This is something you'll need to think about how you want to setup.
Have a look at this thread. I've detailed some "suggestions" and consideration when designing pools that you might find helpful.

What is best antivirus software for Mac Mini? Recently the Trovi virus was on my computer and I want to make sure it is completely gone.

What is the best antivirus software for Mac Mini? I had thought Mac's were safer from viruses but recently I think the Trovi virus infected my computer, I have taken steps to remove but want to make sure computer is clean.

To learn how to defend yourself from the threat of adware read How to install adware.
There will always be threats to your information security associated with using any Internet - connected communications tool:
You can mitigate those threats by following commonsense practices
Delegating that responsibility to software is an ineffective defense
Assuming that any product will protect you from those threats is a hazardous attitude that is likely to result in neglecting point #1 above.
OS X already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
A much better question is "how should I protect my Mac":
Never install any product that claims to "clean up", "speed up", "optimize", "boost" or "accelerate" your Mac; to "wash" it, "tune" it, or to make it "shiny". Those claims are absurd.Such products are very aggressively marketed. They are all scams.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources.
Illegally obtained software is almost certain to contain malware.
"Questionable sources" include but are not limited to spontaneously appearing web pages or popups, download hosting sites such as C net dot com, Softonic dot com, Soft pedia dot com, Download dot com, Mac Update dot com, or any other site whose revenue is primarily derived from junk product advertisements.
If you need to install software that isn't available from the Mac App Store, obtain it only from legitimate sources authorized by the software's developer.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iCloud, iTunes, or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Java can be disabled in System Preferences.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
Beware spontaneous popups: Safari menu > Preferences > Security > check "Block popup windows".
Popup windows are useful and required for some websites, but unsolicited popups are commonly used to deceive people into installing unwanted software they would never intentionally install.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever receive a popup window indicating that your Mac is infected with some ick or that you won some prize, it is 100% fraudulent. Ignore it.
The same goes for a spontaneously appearing dialog insisting that you upgrade your video player right this instant. Such popups are frequently associated with sites that promise to deliver movies or other copyrighted content "for free".
The more insistent it is that you upgrade or install something, the more likely it is to be a scam. Close the window or tab and forget it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. Most of these attempts are pathetic and are easily recognized, but that hasn't stopped prominent public figures from recently succumbing to this age-old scam.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

What is the best word processor for mac? Closest to office?

What is the best word processor for mac? Closest to office?

Welcome to the Apple Support Communities
On OS X, you have some good word processors:
- Microsoft Word for Mac. Included in Office for Mac, it's the best option if you are going to use Word documents with your Mac > http://www.microsoft.com/mac
- Pages. This iWork app is similar to Microsoft Word because both are word processors. This is a good app, too, that you can get from the Mac App Store > http://www.apple.com/iwork/pages/
- LibreOffice. This free suite allows you to do everything that you can do with paid suites but with a free one. It's also open-source > http://www.libreoffice.org
You can read reviews of all of them in the Internet, but I personally prefer Pages. If you want something closest to Microsoft Word for PC, obviously the best option is Microsoft Word for your Mac

Is anybody know best image viewer for Mac..?

Is anybody know best image viewer for Mac..?
I like Windows Explorer Image view .. you just open one file and left and right will scroll though .. can do it in full screen too.
I try a Photo+ and everything is ok, but again must select all pictures or folder to open many photos. I click to one photo in folder, Photo+ open only clicked photos

Try this one... it's called Privcy
https://itunes.apple.com/us/app/privcy/id828281323?ls=1&mt=12
Can easily navigate using cursor keys. What I like is that as you move past the last image it automatically shows the next folder or zip. Ideal for quickly looking at pictures.
Also you can paint/airbrush pictures immediately...

What is the best free antivirus for mac ox iBookG4?

Hi,what is the best free antivirus for mac ox iBookG4?

While no one may be bothering to write exploits in PPC code any longer, at least for Flash, that doesn't mean that there aren't any still floating around. The following doesn't specifically mention PPC/Intel, but that doesn't mean there weren't critical vulnerabilities being exploited for PPC in 10.1.102.64. I wouldn't want to take the chance.
Critical vulnerabilities have been identified in Adobe Flash Player 10.1.102.64 and earlier versions for Windows, Macintosh, Linux, and Solaris. These vulnerabilities could cause the application to crash and could potentially allow an attacker to take control of the affected system.
http://www.adobe.com/support/security/bulletins/apsb11-02.html
And, from TenFourFox
PowerPC plugins are unmaintained and insecure, and Mozilla is changing the plugin environment
No major plugin is being maintained for Power Macs any more: Flash stopped updates with Flash 10.1.102.64 in November 2010, and QuickTime 7 for the PowerPC was decommissioned with the release of QuickTime 7.7 and OS X Lion in August 2011. (Tiger users have not had an update since QT 7.6.4 in September 2009.)
Plugins have special access to the system. When they are instantiated by the browser, they run as if you were running any regular application, which is true even for out-of-process plugins (which were never available for 10.4Fx due to Tiger SDK limitations). Like any buggy or insecure application, they can be exploited or made to crash, and because the plugin runs within the browser, such methods can also be used to attack, spy upon or destabilize the browser as well. They have also been used to attack the network the computer is running on, and a well-crafted attack vector such as that example can run anywhere Flash does, including Power Macs. Because plugins load automatically by default when the page calls for them, your system could be exploited before you even notice.
Many of these attacks can be mitigated, though not entirely prevented, by the use of add-ons that can block plugins from loading. However, there is still another problem apart from security: Mozilla is changing the environment and the technical requirements for how plugins interact with the system. These technical requirements are difficult to achieve with Mac OS X 10.4, and there are known graphical and compatibility bugs already. It is entirely possible that in the near future, extant PPC-compatible plugins will not function properly or at all.

The best Latex Editor for MAC

What is the best Latex editor for Mac ? I'm looking for a suitable alternative to MacTex - either Commercial or freeware.

andy8,
there are quite a few “integrated” solutions, combining editor and pdf preview (the very fine TeXShop being one of them) -- some of them are quite new (even beta); TeXShop, on the other hand, is very mature:
TeXPad:
http://vallettaventures.com/texpad
Latexian:
http://tacosw.com/latexian/
TeXnicle:
http://www.bobsoft-mac.de/texnicle/texnicle.html
Scribo:
http://www.scriboapp.com/
Texmaker (cross-platform, qt-based; all the others are OS X native):
http://www.xm1math.net/texmaker/index.html
You can also check the entries, and the comments, on Macupdate:
http://www.macupdate.com/find/mac/latex
That said, I use none of them, although I have TeXShop around. (This doesn’t mean the new integrated solutions aren’t any good; I haven’t tried them yet.)
That’s because what’s most important, imho, in a good LaTeX environment is the editor, i.e., how much help is there to get the source written. Accordingly, many people would agree that the best editor available plus a fine synchronised, but stand-alone pdf viewer is superior than a (compromising, or so the musing goes) all-in-one tool.
The, hands-down, best pdf viewer, supporting PDFSync (syncing source and pdf), is Skim; it’s free:
http://skim-app.sourceforge.net/
As regards the best editor, there is constant disagreement among OS X users, some would even say “war” -- but that just shows how vivid the Mac ecosphere is when it comes to such tools.
Leaving the “classics” aside, Emacs (Aquamacs, http://aquamacs.org/) and Vim (Macvim, http://code.google.com/p/macvim/), dreaded for their learning curve, worshipped for their power, two of the best, modern, clean, yet powerful editors are TextMate and Sublime Text 2:
http://macromates.com/
helpful: http://www.astrobetter.com/how-and-why-to-use-textmate-for-latex/
http://www.sublimetext.com/2
helpful: http://tekonomist.wordpress.com/2011/03/25/the-in-progress-latex-plugin-for-subl ime-text-2-4/
Many would hold that the combination of either TextMate (2) or Sublime Text 2 together with Skim provides the best LaTeX environment ever.
Take care.

What is the best office program for mac dealing with arabic language?

what is the best office program for mac dealing with arabic language?

The best word processor is Mellel. TextEdit, Nisus Writer, and Open/Libre/NeoOffice should also work OK.
MS Word for Mac does not do Arabic, but I am not sure about Excel and PowerPoint. If not, OpenOffice would be the only option.
iWork has bugs that probably make it unsuitable for RTL for most people.

Best virus software for mac OS 10.5.8?

What is best software for mac OS

VIRUSES
No viruses that can attack OS X have so far been detected 'in the wild', i.e. in anything other than laboratory conditions.
It is possible, however, to pass on a Windows virus to another Windows user, for example through an email attachment. To prevent this all you need is the free anti-virus utility ClamXav, which you can download for Tiger and Leopard (check with them about Lion) from:
http://www.clamxav.com/
The new version for Snow Leopard is available here:
http://www.clamxav.com/index.php?page=v2beta
Note: ClamAV adds a new user group to your Mac. That makes it a little more difficult to remove than some apps. You’ll find an uninstaller link in ClamXav’s FAQ page online.
If you are already using ClamXav: please ensure that you have installed all recent Apple Security Updates and that your version of ClamXav is the latest available.
Do not install Norton Anti-Virus on a Mac as it can seriously damage your operating system. Norton Anti-Virus is not compatible with Apple OS X.
FAKE ANTI-VIRUS SOFTWARE and associated MALWARE
Do not be tricked by 'scareware' that tempts computer users to download fake anti-virus software that may itself be malware.
Fake anti-virus software that infect PCs with malicious code are a growing threat, according to a study by Google. Its analysis of 240m web pages over 13 months showed that fake anti-virus programs accounted for 15% of all malicious software.
Scammers trick people into downloading programs by convincing them that their PC is infected with a virus.
Once installed, the software may steal data or force people to make a payment to register the fake product.
Beware of PDF files from unknown sources. A security firm announced that by its counting, malicious Reader documents made up 80% of all exploits at the end of 2009.:
http://www.computerworld.com/s/article/9157438/in which Rogue_PDFs_account_for_80_of_all_exploits_says_researcher
TROJANS and RE-DIRECTION TO FAKE WEBSITES
The appearance of Trojans and other malware that can possibly infect a Mac seems to be growing, but is a completely different issue to viruses.
If you allow a Trojan to be installed, the user's DNS records can be modified, redirecting incoming internet traffic through the attacker's servers, where it can be hijacked and injected with malicious websites and pornographic advertisements. The trojan also installs a watchdog process that ensures the victim's (that's you!) DNS records stay modified on a minute-by-minute basis.
You can read more about how, for example, the OSX/DNSChanger Trojan works (by falsely suggesting extra codecs are required for Quicktime) here:
http://www.f-secure.com/v-descs/trojan_osx_dnschanger.shtml
SecureMac has introduced a free Trojan Detection Tool for Mac OS X. It's available here:
http://macscan.securemac.com/
First update the MacScan malware definitions before scanning. You can also contact their support team for any additional support - [email protected] [/b]
The DNSChanger Removal Tool detects and removes spyware targeting Mac OS X and allows users to check to see if the trojan has been installed on their computer; if it has, the software helps to identify and remove the offending file. After a system reboot, the users' DNS records will be repaired.
(Note that a 30 day trial version of MacScan can be downloaded free of charge from:
http://macscan.securemac.com/buy/
and this can perform a complete scan of your entire hard disk. After 30 days free trial the cost is $29.99. The full version permits you to scan selected files and folders only, as well as the entire hard disk. It will detect (and delete if you ask it to) all 'tracker cookies' that switch you to web sites you did not want to go to.)

Best financial software for mac

What is the best personal financial software for mac? I am currently using Quicken 2007 but keep losing data.
Thanks,

This is a bash on Quicken reply. I have struggled with Quicken (currently Q07) for many, many years (back into the 90's). I counted 13 different sets of Quicken datasets which have been left hanging on my various hard drives over these years as I found out through different support calls that I would have to discard a corrupted database and start over.
Last year, I was told by Quicken support during a call I paid for that I had too many accounts and the database was too large. (This has been a common tech support comment for me) I've only tried to use Quicken for personal finance tracking, no securities tracking and the heavier features (thank goodness). The call ended with an all too familiar bottom line which was that the backups were all bad so they didn't help. The support person couldn't figure out how I could utlize the backup data so in the end, I re-entered the previous year so that I could get my taxes done and search for another program. I've researched enough to know I was lucky to not move to Quicken Express as was once advised. Apparently that software doesn't allow an export in the event you would find a different software.
The good news is that I just upgraded to Mountain Lion. As you may know, Quicken in any version does not work with this OS. I've finally found a perfect reason staring me in the face to never struggle to use Quicken again. Now to find a better option. Money has many features that seem like what I need for handling 5 or 6 bank accounts and credit cards. Has anyone experienced SEE software? It too seems to have decent features.
I don't know the background of this link but it may be a place to start:
http://personal-finance-software-review.toptenreviews.com/mac-personal-finance-s oftware/
MacWorld also has a review on financial software for the Mac 2013
Best of luck to us all. Deciding on MtnLion and Mac vs. Quicken pppfffft no question which gets dumped!

Best Anti-Virus for Mac.

My new MacBook Pro is getting delievered soon, I want a few opinions on what the best Anti-Virus for it will be. I know that Macs are more secure than Windows, but I still want to have an Anti-Virus on it as I've already had a virus on my current Mac. I have been using Trend Micro on my Mac as I got it free from a rep in my old job. I'm wondering if in the kast year that I've not been working with computers and Macs, has there been a better Anti-Virus made for them? I'd like one that also covers identity theft etc. A few answers would be good for this.... Thanks :-)

This is a very contentious issue, that you will always get different points of view.
IMO, antivirus software is not essential at this stage, however, this does not mean that you should blindly 'surf the net' without a care in the world.
The most recent exploit attempts have used flaws in Java, so the first thing I do is not use Java. Apple does not install it by default, so if you have a new install, then you won't have Java installed, so you cannot be effected by this these types of exploits.
If you do have Java installed, then make sure you have the latest updates from Apple installed, as they introduced features to protect you from these exploits, but also turn off Java if you have not used it after some time.
Java is not used much these days in Web sites, so unless you need it specifically for a site you visit, you probably don't even need it on you Mac at all.
Another recent flash exploit used a default setting in Safari to bypass OSX security settings, this being 'Open "Safe" files after downloading'. Go to Safari > Preferences > General and untick the setting at the bottom of the window, so this exploit cannot be utilised on your Mac.
With Flash, only download it from the Adobe website, and if you get notified by a site that you need an update, I personally go to Adode's web site myself and download updates manually
Other tools you can use to make you Web safer, is to install to extensions to Safari, which are quite good.
WOT - Web of Trust. This is a safety rating of a website to indicate if they are trustworthy or not, Green has been rated as safe, Red not. It is not perfect, but at least gives you an idea if the site is safe or not. As a rule, I don't go to Red sites.
Click to Flash - This prevents Flash from automatically running on sites, and you need to actually click on it on the page to download the Flash. This has two effects, it doesn't load anoying flash onto sites, unless you want it and two, if there are any exploits out there using flash, they can't automatically load.
Ad-Block - Blocks many anoying web ads, if you don't like them.
To install Select Safari > Safari Extensions and search for your desired extension
If you feel you want an Anti-virus application, ClamAV sounds like it is good and it's free without over resoursing your Mac. Remember though, that any AV application is only as good as its database, so if something new comes out it may not protect you anyway. From what I read, many of the AV apps only protect you from Windows viruses anyway, which don't effect Macs in the first place, so seem quite redundant to me.
Also in the background, Apple have a Blacklist of known issues, which they can update to you automatically when new threats are found. If you attempt to install something from one of these, you are notified by a promenent Red message warning you of the issue, allowing you to abort the installation, before it become an issue.
Your biggest AV is you, don't install applications your not sure about. One good thing about the OS, is that to install any app, you need to give your password. If you are not trying to install something at the time, don't give your password over and the app cannot install and cause you any harm.
Don't install MacKeeper if you come across it, its not what it appears, has no ethics and is basically unnecessary.
One thing I also do is use 2 web browsers. I use Safari for my normal everyday browing, and I use FireFox for secure sites such as Banking etc. Firefox I have set to record no history, passwords etc, so there is no record on my computer of this type of information for anyone to access. This protection is more if anyone get physical access to my computer, which in my world, that is entirely possible.
The link AnaMusic posted is a great wealth of knowledge and deffinetly looking at.
As I said, it a contentious issue and there are many different opinions, so I not saying that everything I say is gospel either, just my opinion.

Xcode 3.2.6 best build settings for Mac

Hi!
I'm using Xcode 3.2.6 on Mountain Lion 10.8.5 to create Applescript based applications.
They are tiny utilities that needs more complex UI Applescript can provide.
I''m wondering what's the best build settings for applications aimed to run on Mac OS X
- since 10.6
- non universal binary (no PPC code)
- 64 and 32 bit
Thanks for your help.

Mark,
Now I'm confident about my buids.
red_menace,
Ok. That's what I was affraid about. So if I want to go further, I have to learn AppleScriptObjC.
But the learning curve…
I'm not a developper. Just a graphic designer.
Don't have the time to check out this link, but maybe the solution for a smooth transiton to AppleScriptObjC is there:

What is the best security software for mac?

I had Norton years ago but found it slowed things down unacceptably at the time and so have never revisited it since. However, as internet infection becomes more prevalent on Macs I am considering some kind of protection.
1. What is the general feeling for the most optimal security software for Mac kit?
2. Are there any side effects that one should be aware of which might affect the Mac or software operations?
Thanks and regards

1. This is a comment on what you should—and should not—do to protect yourself from malicious software ("malware") that circulates on the Internet and gets onto a computer as an unintended consequence of the user's actions. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the computer, or who has been able to log in to it remotely. That threat is in a different category, and there's no easy way to defend against it.
If you find this comment too long or too technical, read only sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user. Internally Apple calls it "XProtect."
The malware recognition database used by XProtect is automatically updated; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
☞ It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
☞ It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
☞ It can easily be disabled or overridden by the user.
☞ A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
☞ An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
Apple has so far failed to revoke the codesigning certificates of some known abusers, thereby diluting the value of Gatekeeper and the Developer ID program. These failures don't involve App Store products, however.
For the reasons given, App Store products, and—to a lesser extent—other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandbox security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. The built-in security features of OS X reduce the risk of malware attack, but they are not, and never will be, complete protection. Malware is a problem of human behavior, and a technological fix is not going to solve it. Trusting software to protect you will only make you more vulnerable.
The best defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "Trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the scam artists. If you're smarter than they think you are, you'll win. That means, in practice, that you always stay within a safe harbor of computing practices. How do you know when you're leaving the safe harbor? Below are some warning signs of danger.
Software from an untrustworthy source
☞ Software of any kind is distributed via BitTorrent, or Usenet, or on a website that also distributes pirated music or movies.
☞ Software with a corporate brand, such as Adobe Flash Player, doesn't come directly from the developer’s website. Do not trust an alert from any website to update Flash, or your browser, or any other software.
☞ Rogue websites such as Softonic and CNET Download distribute free applications that have been packaged in a superfluous "installer."
☞ The software is advertised by means of spam or intrusive web ads. Any ad, on any site, that includes a direct link to a download should be ignored.
Software that is plainly illegal or does something illegal
☞ High-priced commercial software such as Photoshop is "cracked" or "free."
☞ An application helps you to infringe copyright, for instance by circumventing the copy protection on commercial software, or saving streamed media for reuse without permission.
Conditional or unsolicited offers from strangers
☞ A telephone caller or a web page tells you that you have a “virus” and offers to help you remove it. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
☞ A web site offers free content such as video or music, but to use it you must install a “codec,” “plug-in,” "player," "downloader," "extractor," or “certificate” that comes from that same site, or an unknown one.
☞ You win a prize in a contest you never entered.
☞ Someone on a message board such as this one is eager to help you, but only if you download an application of his choosing.
☞ A "FREE WI-FI !!!" network advertises itself in a public place such as an airport, but is not provided by the management.
☞ Anything online that you would expect to pay for is "free."
Unexpected events
☞ A file is downloaded automatically when you visit a web page, with no other action on your part. Delete any such file without opening it.
☞ You open what you think is a document and get an alert that it's "an application downloaded from the Internet." Click Cancel and delete the file. Even if you don't get the alert, you should still delete any file that isn't what you expected it to be.
☞ An application does something you don't expect, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
☞ Software is attached to email that you didn't request, even if it comes (or seems to come) from someone you trust.
I don't say that leaving the safe harbor just once will necessarily result in disaster, but making a habit of it will weaken your defenses against malware attack. Any of the above scenarios should, at the very least, make you uncomfortable.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it—not JavaScript—in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Stay within the safe harbor, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
7. Never install any commercial "anti-virus" (AV) or "Internet security" products for the Mac, as they are all worse than useless. If you need to be able to detect Windows malware in your files, use one of the free security apps in the Mac App Store—nothing else.
Why shouldn't you use commercial AV products?
☞ To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. This technique is a proven failure, as a major AV software vendor has admitted. Most attacks are "zero-day"—that is, previously unknown. Recognition-based AV does not defend against such attacks, and the enterprise IT industry is coming to the realization that traditional AV software is worthless.
☞ Its design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere. In order to meet that nonexistent threat, commercial AV software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
☞ By modifying the operating system, the software may also create weaknesses that could be exploited by malware attackers.
☞ Most importantly, a false sense of security is dangerous.
8. An AV product from the App Store, such as "ClamXav," has the same drawback as the commercial suites of being always out of date, but it does not inject low-level code into the operating system. That doesn't mean it's entirely harmless. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An AV app is not needed, and cannot be relied upon, for protection against OS X malware. It's useful, if at all, only for detecting Windows malware, and even for that use it's not really effective, because new Windows malware is emerging much faster than OS X malware.
Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else. A malicious attachment in email is usually easy to recognize by the name alone. An actual example:
London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe
You don't need software to tell you that's a Windows trojan. Software may be able to tell you which trojan it is, but who cares? In practice, there's no reason to use recognition software unless an organizational policy requires it. Windows malware is so widespread that you should assume it's in every email attachment until proven otherwise. Nevertheless, ClamXav or a similar product from the App Store may serve a purpose if it satisfies an ill-informed network administrator who says you must run some kind of AV application. It's free and it won't handicap the system.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have all the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user, you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither can you assume that you will always be safe from exploitation, no matter what you do. Navigating the Internet is like walking the streets of a big city. It's as safe or as dangerous as you choose to make it. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.
