Does my iMac need more RAM?

I have a 4-year old iMac 2 GHz Intel Core 2 Duo with 2 GB 667 MHz DDR2 SDRAM currently running OS 10.8.2. I'm wondering if I should add more RAM. Is there software that will tell me if I need more RAM? I have no idea how much memory is required for the System, or applications like MSWord, Safari, Firefox, MSExcel, or iPhoto when I am using them.

Below is my model information. I have just looked at OWC memory and their video for installation; is OWC something you would recommend?

Old iMac needs more RAM

I have an iMac purchased in 2007 and runs on Leopard. Apparently doesn't have enough RAM to upgrade past Leopard. Is there any way to install more RAM so I can upgrade?

Here are the 2 top sites to buy RAM

Opinions - time for a new computer? need more RAM, Time Machine back up full - get new computer?

I am in a quandary. My early 2008 iMac needs more Ram. I could upgrade from 2gb to 4gb for around $60. My 1T external hard drive for Time Machine is full and I do not relish the idea of it erasing old data if I continue to use it this way, but then I am shelling out more money for a new hard drive. Can get new 3T hd for about $200. Is it worth it to shore up my computer? I have recently upgraded OS to ML and it is really starting to act sluggish. I hate the idea of having to transfer everything over to a new Mac and therefore new OS. I need a working computer every day for business for my husband, so it would be impossible to go without a computer while things are being transferred over - and how long would it take for me to do that. Plus, will files and photos be transferred over exactly as I have organized them? I have spent a lot of time organizing bookmark folders in Safari, mailboxes in Mail and albums and folders in iPhoto. Don't want to start from scratch again. Also don't like the idea that the new iMacs don't have a slot for dvds and cds, playing and burning. I do a lot of this kind of thing. So then I would need to buy a separate thing for doing this as well as the computer itself. Have wondered how many things have changed from ML to Maverick. Another big learning curve???
Would really appreciate any thoughts and opinions. I am a senior citizen and don't know how to sort through this. One thing I think about is that I don't know how much longer I will be living and able to do computer work. I know everything is a risk, but would like some advice even if it is only an opinion.

It's probably time for a new machine. You won't have to start from scratch. Migration Assistant will bring over all of your data and apps (some may need to be re-activated using product keys). Depending on how much you actually have, a few hours should be all it takes over Ethernet.
Time Machine should continually erase the oldest backups when it needs space for new ones.
You might want to do both. Upgrade the RAM in the old machine to the max it will take, and buy a new machine as well. If your husband really needs a machine available all the time for business, having a 'spare' is a good thing.
Check out what's available in the refurb store. They are virtually indistinguishable from new retail stock and come with a full warranty. You can save hundreds.

Does my MacBook White 7,1 need more RAM?

Hi, I'm Federico from Argentina.
It's my first post here. First of all, sorry for my english, hope it's not so bad.
I am photographer and digital retoucher, so, as you might imagine... I use a lot Photoshop (CC).
I'm thinking that I need to upgrade my Macbook to 8gb (now I have 4gb) because my OSX is running slow, and it's affecting my workflow (upgrading to MB Pro is not a chance... no budget for that...).
In the Activity Monitor when retouching in Photoshop memory pressure shows in yellow (Mavericks).
Beyond that, here's my EtreCheck report, I think you may find it useful for troubleshooting my problem.
Thank you so much!

Yes, you need more RAM, but more imprtantly:
Macintosh HD (disk0s2) / [Startup]: 249,2 GB (3,45 GB free) (Low!)
Your Mac is running on vapour! You are risking data loss and a fouled-up system. You urgently need to move files (not applications) to an external hard drive, to leave at least 30GB free.

HT1342 so how do i know if i need more ram? (upgrade from snow- mt. lion)

Here is the mac that i have. I want to upgrade from snow l. to mt, lion when it comes out. articles are saying that i will need 4gb even though the updae page says 2gb. how do i read the activity monitor to see if i need more ram for the update? or do i just need to wait, install teh update, and then check? I want to get this all done in the next month so help would be great!

2 GBs is the minimum required. 4 GBs or more would be better. Your model supports up to 8 GBs.
About OS X Memory Management and Usage
Reading system memory usage in Activity Monitor
Memory Management in Mac OS X
Performance Guidelines- Memory Management in Mac OS X
A detailed look at memory usage in OS X
Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.
Adding RAM only makes it possible to run more programs concurrently. It doesn't speed up the computer nor make games run faster. What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent. It will improve the performance of applications that run mostly in RAM or when loading programs.

It's malware that is making it's way around the net, not a virus.

Does my iMac need antivirus protection

Does my iMac need antivirus software or is it built into the OS X operating system?

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 your 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 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 Internet criminals. 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 red flags that indicate danger.
Software from an untrustworthy source
Software of any kind is distributed via BitTorrent or Usenet.
Software with a corporate brand, such as Adobe Flash Player, doesn't come directly from the developer’s website.
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 popups.
Software that is plainly illegal or does something illegal
Software that you would otherwise have to pay for 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 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 install 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.
Unexpected events
You open what looks like a document and get an alert that it's "an application downloaded from the Internet." Click Cancel and delete the file or message.
An application does something inexplicable, 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" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. 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 "anti-virus" products?
To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. New threats are emerging on a daily basis. Research has shown that most successful attacks are "zero-day" — that is, previously unknown. Recognition-based malware scanners do not defend against such attacks.
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.
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," has the same drawback as the commercial suites of being always out of date, but it does not inject 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 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, and even for that use it's not completely effective. 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 really care? In practice, there's seldom a reason to use the software unless an institutional policy requires it. Windows malware is so widespread that you should assume it's in every unknown email attachment until proven otherwise.
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 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. "Hmmmm, this torrent is a crack of that new game I want. I think I'll download it. It could be a trojan, but the antivirus will warn me if it is." Then they wonder why their Mac is so slow all of a sudden. It's slow because it's running flat out mining bitcoins for a hacker who has already sold their credit card number and banking passwords to a criminal gang. Maybe a week later the antivirus does warn them, but what good does that do?
Nothing can lessen the need for safe computing practices.

My Macbook is very slow, do I need more RAM?

I have checked the Activity Monitor as advised on the forums here and it says 16.3MB free.
It's around 5 years old and I've just upgraded to 10.8.2
I have no idea what this means but I also saw that this number is important?
Page ins 5.92GB
Page outs 6.88 GB
My question is do I need more RAM and if so how do I go about doing it?
Thanks!

Yes, you need more memory. While 2GB is the minimum for OS X 10.8, many have found that 4GB is needed for general performance. For what you run, you can see this in your page in/outs. Page outs generally should be no more than 10% to 15% of page ins. More than that can really slow the system down as it writes pages of memory to the hard drive while making space for something else to use memory.
OWC and Crucial are two vendors that sell quality memory. Your user guide for your MacBook will tell you how to install the new memory.

Does my iMac need anti-virus software

I've read recently that iMacs have been susceptable to viruses. Does my iMac need anti-virus software? And if so, d0es Apple recommend any one in particular?

Mac OS X versions 10.6.7 and later have built-in detection of known Mac malware in downloaded files. The recognition database is automatically updated once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders. In most cases, there’s no benefit from any other automated protection against malware.
The most effective defense against malware is your own intelligence. All known malware that affects a fully-updated installation of Mac OS X 10.6 or later takes the form of trojans, which can only work if the victim is duped into running them. If you're smarter than the malware attacker thinks you are, you won't be duped. That means, primarily, that you never install software from an untrustworthy source. How do you know a source is untrustworthy?
Any website that prompts you to install a “codec,” “plug-in,” or “certificate” that comes from that same site, or an unknown site, merely in order to use the site, is untrustworthy.
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.
“Cracked” versions of commercial software downloaded from a bittorrent are likely to be infected.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. No intermediary is acceptable.
Disable Java (not JavaScript) in your web browser(s). Few websites have Java content nowadays, so you won’t be missing much. This setting is mandatory in Mac OS X 10.5.8 or earlier, because Java in those versions has bugs that make it unsafe to use on the Internet. Those bugs will probably never be fixed, because those older operating systems are no longer being maintained by Apple. Migrate to a newer version of the Mac OS as soon as you can.
Follow these guidelines, and you’ll be as safe from malware as you can reasonably be.
Never install any commercial "anti-virus" products for the Mac, as they all do more harm than good. If you need to be able to detect Windows malware in your files, use ClamXav — nothing else.

Need more ram on 10.4.11, what can i safely dump?

need more ram on 10.4.11, what can I safely dump after saving on x-ternal h/d?

OS X 10.4 is Tiger, and 10.4.11 is the last release. It's been stable for quite some time, so I wouldn't hesitate to upgrade to it. The next operating system upgrade would be to Leopard 10.5, and with a MacBook you could probably upgrade to Snow Leopard 10.6.
When upgrading within an operating system release, ie 10.4.10 to 10.4.11, you don't typically have issues. When going to the next level of operating system, that's where you can run into issues with printer or other drivers and/or programs that need to be updated to run with the newer operating system. With the exception of losing the OS X classic environment when upgrading to 10.5 Leopard and losing the Rosetta emulator (which runs PowerPC code on Intel platforms) when upgrading to 10.7 Lion, for the most part, the upgrades are pretty straight forward.

Does Partitioning Tables need more Space

Hi,
Can some one tell me does Partitioned table need more space than a general tables(i.e with out any partition). If so what can be the percenatge difference.

How do i know if i need more ram

mac is running slow, how do i know if i need more ram?

Well, how much RAM do you have? Post back what you have.
Another possibility is that your hard drive is getting too full - the Mac OS needs a minimum of 10 - 15% of hard drive space free and available at all times. So, click on your hard drive icon once and hit Command and I on the keyboard. In the resulting window, post the results: space available, used, etc.

Does my iMac need an anti-virus or malware detection app to remain secure?

Does my iMac need an anti-virus or malware detection app to remain secure?

The best defense for keeping your Mac secure is YOU. Honestly, I will not tell you to not get software but YOU are the best way to stay safe. I myself have never used any software on my personal computers personally.
rules to remember:
Don't:
Open any e-mails from an unknown sender
Open any e-mails that have attachments unless that person is in your contacts...BUT, this one can be tricky as well. If one of your contacts gets infected, their computer could send an email (with an attachment) to everyone in their contact list. This is a trick to get you to open the attachment because you know the sender. So always check for really generic subject lines that sound fake, call them if you are not sure.
Click on any of those intrusive ads on websites.
Careful downloading software from the Internet that you are not sure about. Always do your research.
if you do decide to get software, I can safely say DO NOT GET MACKEEPER. STAY AWAY. I have heard only horror stories about this software.
Keep your Network safe, make sure if youuse an open WiFi connection to LOCK it.

Videos shot on Canon Vixia HF R20 are jerky on iMac. Do I need more RAM?

Hi. I have a new Canon Vixia HF R20 video recorder. I learned here how to upload videos, but they are very jerky. The first few frames seem OK but then the sound continues and the picture remains frozen, then even the sound breaks up. The red bar continues smoothly to move across the thumbnails. Should I have more RAM or something? I have closed all other progams and restarted but this does not help. I have 10.5.8 and the following:
Model Name:
iMac
Model Identifier:
iMac8,1
Processor Name:
Intel Core 2 Duo
Processor Speed:
2.4 GHz
Number Of Processors:
1
Total Number Of Cores:
2
L2 Cache:
6 MB
Memory:
2 GB
Bus Speed:
1.07 GHz
Boot ROM Version:
IM81.00C1.B00
SMC Version (system):
1.29f1
Thank you in advance!

Is your footage HD? Or what is the pixel size of your videos? I see you have 2 GB, which is at the low end for processing video, especially if it is HD. I have 12 GB and find that is better. I'd at least double yours or max it out; see OWC (macsales.com):

As you can see, Apple officially supports 4 GB, but OWC has tested 6 GB, so the decision is yours.
