What do I need to install win7 in my iMac 2011 21.5" ,and how much

I think all your answers can be addressed in a free session with an apple genius. All of your questions are about things that, as softwater points out, are free.
you have time machine already on your machine, hit command+spacebar and type time machine, hit enter. time machine will come up. Follow the steps it says to set it up.
Boot Camp (which I've never used) is also on your machine already. hit command+spacebar and then type Boot Camp. Hit enter. This is boot camp assistent. Use your CD of windows with this software and you'll be able to boot into windows 7.

I want to set up the Time Machine and I would love to use the Time Capsule but since I already have a wireless router I need suggestions on what other external disks Apple could recommend to use with the Time Machine and how to configure that disk

I want to set up the Time Machine and I would love to use the Time
Capsule but since I already have a wireless router I need suggestions on
what other
external disks Apple could recommend to use with the Time Machine and
how to configure that disk.
A complication that I need to resolve is the fact that I am using Vmware
Fusion to be able to use Windows on my Mac. Now it seems that Time
Machine is not backing up my files
on that virtual Windows without additional configuration and my question
is whether you can advise me here or whether this is only a matter for
the Fusion virtual machine.

If you want to use Time Capsule you can.. you simply bridge it and plug it into the existing router.. wireless can be either turned off or used to reinforce the existing wireless.. eg use 5ghz in the TC which is much faster than your 2.4ghz.
You can also use a NAS.. many brands available but the top brands are synology, qnap and netgear readynas series. These will all do Time Machine backups although how well always depends on Apple sticking to a standard. There are cheaper ones.. I bought a single disk zyxel which was rebadged and sold through my local supermarket. It actually works very well for TM at least on Snow Leopard. Major changes were made in Lion and again ML so do not instantly think it will work on later versions. I haven't tried it yet with those versions.
Any external drive can be plugged into the mac. Use the one with the fastest connection or cheapest price according to your budget. USB2 drives are cheap and plentiful. But no where near as fast as USB3 or FW800. So just pick whichever suits the ports on your Mac. Interesting Apple finally moved to USB3 on their latest computers.
TM should exclude the VM partition file.. it is useless backing it up from Mac OS side.. and will slow TM as it needs to backup that partition everyday for no purpose.. TM cannot see the files inside it to backup just the changes.
You need to backup windows from windows. Use MSbackup to external drive.. if you have pro or ultimate versions you can backup to network drive. But MSbackup is a dog.. at least until the latest version it cannot restore the partition without first loading windows. There are about a zillion backup software versions for windows.. look up reviews and buy one which works for you. I use a free one Macrium Reflect which does full disk backups and is easy to restore.. to do incremental backups though you have to pay for it.

I need to add more RAM, what do I do and how much do I need?

I have an imac. It is a 21" 2011, 10.8 op system with 4 gigs of ram. It has begun to show the "colored wheel" and a few of the programs that require a lot of ram lock up. I was told I needed more RAM. Where do I buy it, what kind do I need, and how much do I need?
Do I need to buy it in pairs?
Thanks for the help, Mike

Since installing OSX 10 my iMac randomly shuts down and restarts. I can not determine why this is happening. Any ideas?

Since installing OSX 10, my iMac randomly shuts down and restarts. I can not determine why this is happening. Any ideas?

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. 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 victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
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, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; 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.
For the reasons given above, App Store products, and 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. Sandboxing 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're not absolute protection. The first and best line of 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 malware attacker. If you're smarter than he thinks you are, you'll win.
That means, in practice, that you always stay within a safe harbor of computing practices. How do you know what is safe?
Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is unsafe.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders" are outside the safe harbor, though not all are necessarily harmful.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe. For instance, if a web page warns you that Flash is out of date, do not follow an offered link to an update. Go to the Adobe website to download it, if you need it at all.
Even signed applications, no matter what the source, should not be trusted if they do something unexpected, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
"FREE WI-FI !!!" networks in public places are unsafe unless you can verify that the network is not a trap (which you probably can't.) Even then, do not download any software or transmit any private information while connected to such a network, regardless of where it seems to come from or go to.
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.
Follow the above guidelines, 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" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. If you need to be able to detect Windows malware in your files, use one of the free anti-virus products in the Mac App Store — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their 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, the 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.
To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. Most of the real danger comes from highly targeted "zero-day" attacks that are not yet recognized.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
8. An anti-malware product from the App Store, such as "ClamXav," doesn't have these drawbacks. That doesn't mean it's entirely safe. 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 anti-virus app is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
Anti-virus software may be able to tell you which particular trojan it is, but do you care? In practice, there's seldom a reason to use the software unless an institutional policy requires it.
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 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 should you assume that you will always be safe from exploitation, no matter what you do. 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.

Hi, my name is Laith I'm from Iraq I just want to know what are the steps for buying a new iphone 5 from apple store and how to ship it to Iraq ???? and I would be grateful for you

Legality aside (I'm not a lawyer and have no opinion on the matter) in order to make a purchase of an iPhone 5 you would need to travel to a country where they are for sale and purchase it there. Be sure to get one that is officially unlocked or you would not be able to use it with your cell carrier. Be sure that your carrier supports use of the iPhone before you buy. Also note that the warranty of the iPhone is only valid in the country of purchase.
Appe does not ship outside of the countries where it sells the phones.

How can i have the detail of the things i bought ,what ,when,and how much?

There are instructions on this page for managing and stopping auto-renewing subscriptions : http://support.apple.com/kb/HT4098
To view the purchase history on your account, log into your account on your computer's iTunes via the Store > View Account menu option, and you should then see a Purchase History section with a 'see all' link to the right of it. Click on that and you should then see a list of your purchases

This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you boot, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, reboot as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

How do I see a detailed view of what's on my hard drive and how much space it's consuming?

I have an early 2007 iMac (3GB RAM) and a 320 GB hard drive. I'm trying to clear some of the programs and files I don't need to free up space, but I'm not sure how to get a similar look at my files and how much space they take up individually (as I would with a PC). Under system info I'm able to get the high-level overview, but how do I see a detailed view that I can then edit?

Thanks for your help. I did just that and was able to get a much better view with OmniDiskSweeper. I was shocked to find that my MobileSync files were 125 GB of about 270 being used! Guess I shouldn't be surprised with 4 iPhones and 4 iPads syncing to the same iMac at one time or another -- just kind of surprised Apple/iTunes doesn't make it any clearer that this can turn into a big problem if you don't initially create the appropriate backup settings for your devices. Thanks again!

No, you simply do not. Apple does not sell insurance.
Apple offers an Extended Warranty called AppleCare.
Warranties doe not cover lost or stolen devices. Buy a new one.

What is the best app for following of the download? I mean how much I downloaded using WIFI and how much 3D download.

I would like to follow the amount of MB I downloaded and to know how much data was downloaded using WIFI and how much using 3G (internet connection by phone network provider as AT&T and so...).
Thank you very much for any suggestions.

Personally I have tried LogMeIn Ignition, Splashtop, and AlwaysOnPC, as well as TeamViewer. Although LogMeIn Ignition is expensive I would also have to say that it is the best one I've tried. Apart from viewing the computer's screen, you can access the files and folders in a standalone file browser interface without seeing the computer's screen, this speeds things up a lot.
As for security, I'm not too sure, as the website for LogMeIn does not seem to list the details. But as with any other internet based service, like email and social networking sites, an additional account of any sort will increase your vulnerability, even if it's just by that small amount. You can try accessing the computer through a VPN when on a public wifi network for added security. However about the virus, I don't think that is possible... No need to worry about your iPad getting a virus.

My iphone 4s fell from the bed and the front screen glass got cracked but the touch screen is working fine, so can i replace just that screen glass?? If not what am i to do ? And how much it might cost me for that repairing??

I don't know. You'll have to ask.
FYI, if the phone was not originally sold in India, it can not be serviced in India. You will have to take it back to the country where it originated.

How can I tell what video card and how much video memory does my iMac have?

How or where can I find out: which video card does my iMac have and how much video memory does it have? I've tried looking in System profiler, but I did not see it there. Thank you.

Once you open System Profiler there should be a line called "memory" which is the RAM (vs. hard drive size which is not what is called memory), e.g., Memory: 1.5 GB
For video click on the line Graphics/Displays and look at the chipset line, e.g., Chipset Model: GeForce2 TwinView
Kappy's instructions are handy for checking the original configuration of your computer, but that may have been changed at some time, especially if you bought it secondhand.

Is there any command/query/etc, which would allow to understand what database objects (for example tables) are consuming memory and how much of it?

TimesTen Release 11.2.1.9.6 (64 bit Linux/x86_64)
Command> dssize;
PERM_ALLOCATED_SIZE:      51200000
PERM_IN_USE_SIZE: 45996153
PERM_IN_USE_HIGH_WATER:   50033464
TEMP_ALLOCATED_SIZE:      2457600
TEMP_IN_USE_SIZE:         19680
TEMP_IN_USE_HIGH_WATER:   26760
Is there any command/query/etc, which would allow to understand what database objects (for example tables) are consuming memory and how much of it?
tried to use ttsize function, but it gives some senseless results – for example, for the biggest table, tokens, it produces following output (that this table is 90GB in size – what physically cannot be true):
Command> call ttsize('tokens',null,null);
< 90885669274.0000 >
1 row found.

Are you able to use the command line version of ttSize instead? This splits out how much space is being used by indexes (in the Temp section of the TT memory segment), which I think is being combined into one, whole figure in the procedure version of ttSize you're using. For example:
ttSize -tbl ia my_ttdb
Rows = 4
Total in-line row bytes = 17524
Total = 17524
Command> create index i1 on ia(a);
ttSize -tbl ia my_ttdb;
Rows = 4
Total in-line row bytes = 17524
Indexes:
Range index JSPALMER.I1 adds 5618 bytes
Total index bytes = 5618
Total = 23142
Command> call ttsize ('ia',,);
< 23142.0000000000 >
1 row found.
In 11.2.2 we added the procedure ttComputeTabSizes which populates system tables with detailed table size data, and was designed to be an alternative to ttSize. Unfortunately it still doesn't calculate index usage though, and it isn't in 11.2.1.
