What is the best security package for an imac using yosimity

What is the best security package for an imac using Yosimity

Mac users often ask whether they should install "anti-virus" software. The answer usually given on ASC is "no." The answer is right, but it may give the wrong impression that there is no threat from what are loosely called "viruses." There is a threat, and you need to educate yourself about it.
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 take control of it remotely. That threat is in a different category, and there's no easy way to defend against it.
The comment is long because the issue is complex. The key points are in 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 taken far too long to revoke the codesigning certificates of some known abusers, thereby diluting the value of Gatekeeper and the Developer ID program. Those lapses 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, not machine behavior, and no technological fix alone is 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 Internet criminals. If you're better informed 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 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. A genuine alert that Flash is outdated and blocked is shown on this support page. Follow the instructions on the support page in that case. Otherwise, assume that the alert is fake and someone is trying to scam you into installing malware. If you see such alerts on more than one website, ask for instructions.
☞ Software of any kind is distributed via BitTorrent, or Usenet, or on a website that also distributes pirated music or movies.
☞ Rogue websites such as Softonic, Soft32, 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. All "YouTube downloaders" are in this category, though not all are necessarily malicious.
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 padlock icon in the address bar 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 can be 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.

How can I find what apple ID I used to register my iMac when I first booted up? I am being told that by using this ID I will be able to go on to the App store and down load iPhoto at no cost. Is this true? My iMac does not have iPhoto resident on it now

Is this true? My iMac does not have iPhoto resident on it now and I only purchased my new iMac in December 2012
Thanks....

Launch Keychain Access and click on Login in the left hand pane and then on Passwords. Next do search for Apple in the search field at the top and click on Apple ID Authenicication in the list that comes up. That will give you the ID no. and password.

HT5304 what is the best way to connect my imac wireless with airport express or directly plugged into airport unit

what is the best way to connect my imac to internet via airport express. wireless or ethernet plug to airport? thanks

Hello quinstar,
It sounds like you would like to use either your Personal HotSpot to AirPrint from your MacBook Pro or use an Airport to do so without internet access to the home. According to the following Featured Discussion you very well may be able to use AirPrint with Personal HotSpot:
HT4356 Can I use personal hotspot as wifi to connect printer?
https://discussions.apple.com/thread/4007254
Also, the Airport products to not need an active internet connection to set up a home Wi-Fi connection so that is another option as well.
Thank you for using Apple Support Communities.
Take care,
Sterling

Does anyone know why or what is the reason when starting a new iMac with Lion a gray bar sometimes appears when loading software?

Does anyone know why or what is the reason when starting a new iMac with Lion, sometimes a gray bar appears under the Apple that begins to shade to dark as it loads OS? It does this on occasion. One time the system loaded was VERY slow and terrible colors. Pulled the plug, re-started the computer and it did not do this. As I say, its only on occasion, not every time. I noticed in the discussion page there were problems listed for 10.6 nothing for Lion.
Please advise, if possible.

You should see this 4 option menu. Click on Disk Utility:
In Disk Utility, Select FIRST AID and then VERIFY and then REPAIR the disk.
Ciao.

What is the amount of DVDs that an iMac DVD Burner can burn? (or MTBF)

What is the amount of DVDs that an iMac DVD Burner can burn (DVD burner life time)? (or MTBF)

Your question sounds a bit like you want to use the Superdrive professionally? Personally, I would not depend on a vertically installed, super slim Drive where any media can easily shift by 1/100th of an inch. I've noticed that mine definitely needs to "rest" and cool off after about 3 DVDs. I purchased an external burner quite a few years ago (when I had an iMac without a Superdrive) and I still prefer to use it - it is sturdy, can read all sorts of media, and is reliable whereas the SuperDrive is known to be extremely finicky especially about the media they will read or write to.
So, I don't have a specific answer for you, but I wouldn't rely on it.

What regular maintenance needs to be done on iMac to keep it running efficiently?

What regular maintenance needs to be done on iMac to keep it running efficiently?

As long as you don't have to force quit your computer because it has crashed, then the only things year really need to do is (1) maintain a current backup (preferably more than 1 actually, I like to keep one backup out of the house in case there's a fire or theft) and (2) keeping your software and OS up-to-date.
If you experience a kernel panic (your screen will darken and you'll get the message to restart your computer - in several languages) or if you have to hold the power key to force a restart you may experience disk corruption. After such an event you should run Disk Utility and perform a verify disk. This won't repair the damage but will tell you if you need to repair the damage. If you do get such a message, depending on your circumstances and the OS you are using, you'll need to restart your computer with the OS installation DVD or the recovery partition (if you have Lion) and run the repair disk function in Disk Utility.
Windows users are used to doing much more to keep their computers healthy but this is really all you need to be concerned with on a day to day, month to month basis with a Mac.

What is best password AP to sync with Imac (Snow Leopard)?

What is best password AP to sync with Imac (Snow Leopard)?

Here are a few analog to digital devices and approaches I have had success with:
1. Sony DA-2
2. Most Name brand Firerwire or i.Link Minidv Camcorders with Digital Pass thru feature will suffice since more often than not this feature is also included ... But read the owner's manual or check online to make certain it's included.
3. Canopus products work perfectly nearly 100% of the time and will keep the video and audio in synch much better than other devices. It can take the form of a pci card (if your mac is so equipped) and if not, then a canopus media converter box will also work (as already mentioned above):

What is the latest software version for my iMac? I have version OS X version 10.7.5

What is the latest software version for my iMac? I have version OS X 10.7.5

Welcome to Apple Support Communities
You have OS X Lion. OS X Mountain Lion is compatible with Mid 2007 (iMac7,1 or newer) iMacs, so to check that you have a compatible Mac, press , hold the Option (Alt) key and open System Information. Then, check Model Identifier. Also, the App Store will tell you if your iMac is supported when you try to purchase OS X Mountain Lion, so you can skip this step.
While it's being downloaded, make a backup of your files with Time Machine and check that your applications are supported > http://www.roaringapps.com
When the download finishes, the OS X Mountain Lion installer will appear, so follow the steps. You will be running OS X 10.8.4
