Use of MBP memory in iMac

I have a 17" MBP purchased last year, it has 4GB 1066MHz DDR3 SODIMMs, 2 x 2 GB, in it. I have on order - IF PC Universe ever decides to actually ship it; another story - 2 x 4GB of 1066 MHz DDR3 SODIMMs, this will boost my MBP to 8GB, the max.
My iMac uses 800 MHz DDR2 SODIMMs, it currently has 2 x 1 GB strips inside. The iMac supports up to 4 GB.
Can I use the 2 x 2 GB 1066 MHz DDR3 strips that will be liberated from my MBP when I get the memory upgrade, will they work in the iMac?
Thanks,
Lawrence

will they work in the iMac?
No.

Bought used G Skill memory for iMac - Kernel panics

Memory has PC part no. F3-10666CL9S-4GBSQ - Mac part no. is identical except for an FA instead of F3 what is difference? Or is it incompatible generally? Or just bad memeory?

You either purchased incorrect RAM or did not install it correctly or the RAM is defective. Those are the ONLY 3 possibilities with new RAM causing KP's. While some KP's can be tricky to figure out with new RAM those 3 issues are it. So either double check to see you got virtually identical specifications to what Apple recommends, you installed it incorrectly (it is possible it's not fully seated) or you got a defective DIMM(s).

HT1270 Used the right memory, both for my iMac and MacBook Pro, iMac worked, MacBook Pro didn't start (warning tone). Any idea?

Used the right memory according to page, both for my iMac and MacBook Pro, iMac worked, MacBook Pro didn't start (warning tone).
Any idea?

I suggest you buy your memory from OWC or DataMem. Both guarantee the memory works or will replace it if it does not, no questions asked, within their 30 day return period. I've used both for over 20 years, and no complaints.

Does the new iMac use the same memory as the previous?

Right now i have the 24" 2.16ghz iMac and i am considering selling it to buy the newest 24" 2.4 ghz version. My question is, do they use the same ram? The apple specs page for the new imac says it uses 667MHz DDR2 SDRAM (PC2-5300) which is what i thought i had in my current iMac. For some reason though on crucial's website it says the new imac uses 800mhz ram, i would likely trust apples specs but i just wanted to confirm if it is the same so i know if i can keep a 1gb stick or not to put in the new one. Thanks!

By using the manual method (Apple > iMac > 2.8 GHz) I only got PC2-5300 (667 MHz) RAM (although I do get PC2-6400 RAM for the 2.4 GHz model - but you probably won't benefit from the performance boost, just like my Mini has now 1 GB of 400 MHz DDR RAM running at 333 MHz). And yes, the new iMac uses the same RAM as the older one.
I'd suggest you visit an Apple store and see the new iMac for yourself though. Your iMac still seems like a pretty good computer, and the 2.4 GHz processor and/or Radeon HD 2600 card may not warrant the upgrade price, especially if you don't like the glossy screen (which is reportedly much glossier than the MacBook's display).

MBP Memory Upgrade Using More RAM than Before

Hey,
I have a 13-inch, late 2011 Macbook Pro with a 2.8 GHz Intel Core i7 Processor. I recently changed my 4GB memory (2 modules) PC3-10600 DDR3 1333 MHz to a Crucial 16GB PC3-10600 DDR3 1333 MHz.
Before the upgrade, the activity monitor would show memory used at around 3.98GB or so, and I was running only chrome with a few tabs open. Using chrome and a few more apps would slow down the computer significantly, though still usable.
After the upgrade, the activity monitor shows memory used at around 6.5GB with the same apps running (just chrome). My computer does run a faster and can handle a lot more apps.
My question is, why is my Macbook using more RAM after the upgrade?
Thanks,
Sebs

The short answer is that memory unused is memory wasted.
Mavericks is designed to decrease reliance upon mass storage, which is orders of magnitude slower than RAM. Mavericks will use all the memory available to it before resorting to using the swapfile. You are likely to find "swap used" to be zero, even with Google Chrome's notoriously profligate use of system resources.

HT1423 after memory upgrade iMac crashes

I upgraded the memory on my iMac 21.5 mid 2010 in accordance with the instructions and now it continues to reboot and after a while the screen turns black and a beeping sounds occurs. Suggestions to resolve this are welcome.

The specs are correct and have used Corsair Mac memory. Have used this brand also to upgrade another iMac and a Macbook Pro
So have I, my Early Core Duo has had 2 1GB PC2- 5300 667MHz Corsair modules in it for years and has never had a problem.
If you are sure that the modules a fully seated in the slots, then the only conclusion is that there is something wrong with that RAM.

Want to use Dell Laptop/Dock with iMac Display

Hello, i currently have a MBP and a Work Laptop (Dell with Dock) and i would like to change my MBP to a iMac but i would like to use the same display on the iMac for the laptop dock too.
Is this possible?
I have read a couple of posts and am i right in thinking that there is no way of doing this with the new iMacs or the very new iMacs getting released in Nov/Dec?
Do i need to buy a 2009/2010 iMac and if so, is this easy to hook up?
Thanks
Barry

I just checked my laptop outputs, it does not appear to have a display port out, but the dell dock it sits in does.
Will this just need a display port to mini display port?
Thanks

Use the MBP as a display

Two questions:
1. Is there a way to use a MBP (or even a iMac or just a PC monitor) as a display for an XBox 360 using some sort of cables and converters.
2. I have an old iMac G5 running Panther and is there a way to just use that as an additional display. (I am already using a secondary)

Hi,
As far as I know, you need a video-input card (or more commonly known as a TV card) to do this. You might want to have a look at the EyeTV products (http://www.elgato.com/).
Be careful though, there are two kinds of TV cards: one which uses hardware compression, and the other which uses software compression. Software compression uses your computer processor to process the video signals. Hardware compression does the video processing knick-knacks on the TV card hardware, which frees up your computer while usually giving better video quality, especially on older computer systems. However, the downside of hardware compression is the lag time to show the video on your computer monitor, which is a no-no for gaming systems like the XBox360.
Hope this helps.

Backupd process using too much memory, blocking up system (Yosemite)

Hello,
Since I upgraded to Yosemite (maybe even only after I installed 10.10.1) on my Early 2009 17" MacBook Pro, after a while, a process called "backupd" is started, using all available memory, then switching to virtual memory. After a few hours, it can take more than 20 GB of virtual memory, making the MacBook Pro very slow and unresponsive. Killing the process using Activity Monitor (which can take many minutes because of the unresponsiveness) regains the used memory, and almost immediately makes the machine responsive again.
What is this "backupd" doing anyway, are there means to prevent it from running at all or to let it stop using so much memory, or might there be a bug in OS X 10.10.1?
Cheers,
Dirk

I did that anyway yesterday, to turn off the mobile backups, as my MBP is not so mobile anymore
Let's see if it works and if the problem is solved by it

A little memory and imac selection advise needed

This new round of core 2 duo imacs are making me FINALLY comfortable in switching to the Mac. Primarally for video editing. Can't afford FCP so FCE will be my choice. I also am a Adobe CS2 user. The current machines come with 1 gig of memory. Would I be ok with that amount or would I soon regret not paying the $175 for uping it to 2 gig? Also, screen size. Using the machine mostly for photos and video, is $500 worth the 4 extra inches? I've seen these machines at a local apple store and they are beautiful to say the least. I just didn't know if the 24 was a little over the top or not.
Any advise?

Hi(Bonjour)!
Get as much memory as you can, specialy if the extra chips are added at apple factory if the extra modules replace the originals one, leaving two slots available for future expansion( in fact: 2 slots because memory module are added in pair set, there are 4 slots used in pair in intel iMac: 2 filled with factory installed modules, and 2 free).
Ask for this information when buying from apple store, may be the newer models don't have this limitation as pre-intel iMacs.
Third party memory is usually cheaper that apple's one, but you'll have to use the third and forth slot. If your needs exceed this amount in future, you'll have to replace two modules with a bigger ones, leaving two smaller modules unused in your hand.
For your screen question:
as I see on apple imac's web site:
-the 24" model offers 1920 by 1200 pixels display area (16:10 aspect ratio). That seems that your can preview HDV content at full resolution (like on Apple Cinema HD display 23" and 30 " 16:9 aspect ratio).
-the 20" model offers 1680-by-1050 resolution (16:10 aspect ratio), not enough for HDV display in full resolution, but okay for previewing scaled down HDV content.
You get wider viewing angle with the 24", but the same contast ratio for two models.
If you plan to do some HDV editing in future (FCE HD can do that), the extra cost is okay.
Pay attention to buy the current version of Final Cut express HD 3.5 to use it with intel iMac. Previous version are not universal one.

I cannot see my MBP (Lion) from iMac (Leopard)

We have a suite of iMacs in our office, and I've never had a problem before finding my laptop (MBP) from those iMacs. However, since buying a new MBP (Lion) a few months ago, I cannot see the computer listed. I can connect by typing in the afp:// location, but this seems like more hassle than it should be. I am also unable to see the iMacs (most are 10.5.8) from my MBP. Can anybody tell me what I might be doing incorrectly? File sharing is turned on. Thanks.

I assume you are using a mini-displayport/thunderbolt to HDMI adapter.
Did you set the TV to take its input from the HDMI connection?
Since you don't see the Arrangment tab in your Displays preferences there's probably something physically wrong with your connections. Try clicking detect displays just to see if the computer can now sense the presence of the connection. Check your cables and make sure the mini-displayport plug is pushed firmly in. Mini-displayport plugs can be a little tricky in that you need to make sure the plug is fully seated in their socket.
Once you have an Arrangement tab, and it shows two screens, then click Gather Windows to bring the TV's Displays preferences on to your main screen if the TV is not yet showing an image. Set the proper resolution (probably 720p, 1080i, or 1080p). Set the refresh rate (probably 60Hz) if that preference is shown. You should see a picture at this point. I recommend turning off mirrored displays if it is enabled.
You may have to play with the underscan/overscan settings on your TV and the displays prefs for the TV if the picture is too small or larger for the TV screen.

Use Secure Virtual Memory - An observation

I recently noticed that my MacBook Pro, with a fresh install of Snow Leopard, had the item "Use Secure Virtual Memory" checked in the Security Preference Pane. A little research on these forums and I learned that was a new feature of Snow Leopard and it is on by default for portable computers and off by default for desktops.
The threads that I read in researching this touched on who needs this turned on and why as well as potential performance implications of having this turned on. The general message was that the load on the CPU would probably not be noticeable given the disparity between disk performance and CPU performance.
I had used my freshly rebuilt MBP with this option turned on for a couple of weeks when I noticed it and turned it off. While I'll agree that from a performance / response perspective I noticed no difference between it being on or off there was another measurement that did show a noticeable difference. I always run temperature monitor, including my CPU temperature, on my MBP, it ends up being sort of an early warning when something is beginning to make the CPU work harder than normal. Since turning off the "Use Secure Virtual Memory" option I can confidently say my typical CPU temperature has dropped between 6 and 9 degrees Fahrenheit for each working set of applications / activities that I do with my computer. So while there may not be a performance gain per se, clearly the CPU is working a little less with this option off.
Just wanted to share this for others to make an informed performance perspective decision on using this option.

It seems like the default for Mac Laptops is ON, while the default for Mac Desktops is OFF...

"Use secure virtual memory" doesn't encrypt swapfile

System: Fresh install 10.5 with full patches to 10.5.1 G4 iMac.
No matter what I did with the "Use secure virtual memory" option in System Preferences, the -E switch did not get passed to dynamic_pager.
Setting ENCRYPTSWAP=-YES- in /etc/hostconfig also had no effect.
So I forced it in /System/Library/LaunchDaemons/com.apple.dynamic_pager.plist and verified that the -E switch is being passed to the dynamic_pager on startup. Guess what? The swapfile still appears to be in-the-clear.
So I thought the contents of /var/vm/swapfile0 might be left over from a previous boot so I booted into single-user and ran +rm -P /var/vm/swapfile0+ then booted normally. Still appears to be in-the-clear:
root# strings /var/vm/swapfile0 | grep -i password
2/Applications/Utilities/Open Firmware Password.app
*/Applications/Utilities/Reset Password.app
com.apple.openfirmwarepassword[
com.apple.OpenFirmwarePassword
Open Firmware Password

Contents/Resources/PasswordReset.icns
Contents/MacOS/Reset Password
root# ps -ax | grep dynamic_pager
72 ?? 0:00.01 /sbin/dynamic_pager -E -F /private/var/vm/swapfile
The technical term for this is "BAD."
*Is encrypted swap a feature of Leopard or not?*
I've seen discussions that this also applies to Leopard Server. I haven't looked at Tiger client or server yet.

I was looking at this myself, more so because I was having performance issues and wanted to see if secure virtual memory was worth it. I encountered the same issues you had with the "Use secure virtual memory" checkbox. It seems that it isn't working. But then I spent like 5 minutes trying to understand the explanation in help:
Use secure virtual memory: Select “Use secure virtual memory” to erase any information from random-access memory written to the hard disk by virtual memory.
Keyword here is "erase" not necessarily "encrypt". This is my understanding of virtual memory. Let's say you have some application that uses a password. that application gets pushed to virtual memory. You access the application so it gets placed back in RAM. When this happens, and if you have secure virtual memory enabled, it will erase the information from the virtual memory. Without secure virtual memory that information still lingers in there till reboot and the swapfile is cleared. It's not necessarily encrypted though.
Now, why when you specify the -E option and it doesn't encrypt the swapfile I'm not sure. the man page is rather vague, but does say that -E encrypts the swapfile.

How can I share printers using a non apple router, imac to ipad?

Newbie in osx, but experienced in linux.
My new imac has 3 printers setup for sharing, but ipad 2 / iphone 4 fail to see them. I am using the belkin router that I owned already, instead of buying an Airport.
I found a solution at askubuntu.com Q 26130 at http://askubuntu.com/questions/26130/how-can-share-my-printer-so-that-i-can-use- it-with-airprint
I setup a linux machine on the network, with no physical connection to any printer. The 1st, an hp fax psc has a usb to imac, as the 2nd, an hp psc, the 3rd printer is an epson wireless, which is only connected on the network by wifi to the belkin router. I'm certain the imac "sharing" is properly setup, because the linux machine has no trouble finding the printers. Only the ipad / iphone have a problem.
Once I put the linux machine (with the above changes) on the network, everything works as desired. I can print on the ipad / iphone to any of the 3 printers, using the built in Airport printer routine (not the epson or hp apps). And the imax and linux machines can also print on all 3.
So, I suspect the imac isn't telling the router to display the printers on the network in a way that iOS can see them. I know it would work if I owned an Airport, but I'd rather not spend that much right now.
I'm sure someone knowledgable in OSX might have an idea where to stick an Airport definition file, created from the python script in askubuntu, that could solve this without having to run the linux laptop all the time. Any ideas?
TIA

It's possible to use free software (Virtualbox and Ubuntu) to fix the broken iOS 5 Airprint printing with non supported printers. Here's a fix that works on my imac, but should also work on even a windows pc.
My setup is a lion imac with 2 non-airprint supported usb printers attached, a belkin wifi router that provides network connectivity for my imac, ipad, and iphone.
Install ubuntu 11.10 in a virtualbox vm. Specify to use the "Bridged Adapter" with "en1: WiFi (AirPort)" for the network hardware. Make sure the imac's usb printers are setup with sharing. On ubuntu, select System Settings > Printers and add your imac's shared printers to the list. Then start ubuntu's firefox and set "localhost:631" in the address. On the administration tab, under the Server section, check "Share printers connected to this system" and hit Change Settings button to activate it. Go back to ubuntu's printer setup, and right click on each printer and check that the properties Policies tab does not have any messages about it being unshared. If so, then go back to firefox and make sure the Server sharing checkbox is enabled. It may help to reboot.
Fire up virtualbox to be able to use AirPort printing to your imac's usb printers, when you want to print from the iphone or ipad. This also works on iOS 5.
Only problem is error message from iphone to check the printer for errors, even though it actually prints ok.

I want to ask something about firefox. why firefox use very much memory? can you develop to reduce memory comsume? this problem is very distrub in my PC with low memory.

I want to ask something about firefox.
why firefox use very much memory?
can you develop to reduce memory comsume?
this problem is very distrub in my PC with low memory.
== This happened ==
Every time Firefox opened

How much memory is Firefox using right now?
# Press '''CTRL+SHIFT+ESC''' to load the Task Manager window
# Click the Processes tab at the top. (Click once near the top of the window if you don't see tab
# Find firefox.exe, and see how many kilobytes of memory it's using.
Showing around 80MB when Firefox first starts is normal. Right now, I have 75 tabs open and it's using 500MB - this varies a lot depending on what you have in the tabs.
Other than high memory usage, what other problems are you experiencing? (Examples include slowness, high CPU usage, and failure to load certain sites)
Many of these issues, including high memory usage, can be caused by misbehaving add-ons. To see if this is the case, try the steps at [[Troubleshooting extensions and themes]]. Outdated plugins are another cause of this issue - you can check for this at http://www.mozilla.com/plugincheck
