B&W G3 RAM into G3 iMac?

Is it possible to put RAM that I have installed in my B&W rev2 450MHz G3 into a 500MHz G3 iMac and vice versa?
B&W G3 450MHz w/ 1GB RAM, 9GB HD Mac OS X (10.3.9)

Those Macs may have a different row and column organization. This would show up as only part of the memory being recognized.
But the important thing is to know that no damage will result. Try it! And then please post your results so all can benefit from your experiments.

I7 RAM into a iMac 5,1?

Hey there,
I recently purchased a 27" i7 iMac and upgraded the RAM. Now I have 2 2GB sticks that I was hoping to install into my dad's iMac 5,1. Browsing the web, it looks like it might not be compatible, but I was hoping for a definitive answer from someone who really knew. Any chance of this working?
Thanks!
Brian

I'll second that!
No the new iMac RAM is totally different, different speed, different latency, different pin count and notch location than the earlier 5,1 iMac takes.

Can i plug an usb drive into a iMac and access it with a Macbook pro?

I have an iMac that is less than 3 months old and my wife now has a two week old Macbook Pro.
IMac:
21.5" screen
3.1 quad core i7
16 GB Ram
1 TB Fusion drive
Macbook Pro:
13" screen
3.0 dual core i7
8 GB ram
512 GB Flash storage
Both have Mountain Lion.
Both are running iOS 6.1.2
I would like to attach an external USB hard drive to the iMac and allow the Macbook Pro to be able to have full access to just the external USB hard drive. Either it can't be done or I am just not getting the Sharing settings set correctly. I played around with sharing last night on both machines. When I would plug in a FAT 32 thumb drive into either machine and find it, I would add it to he shared folder but it would only allow me and "Everyone" to have access. I could not change "Everyone" to "No Access" because "Everyone" was greyed out or add my wife. I can access the Macbook Pro as Mark with the iMac but I can only access the iMac from the Macbook Pro as a "Guest".
I am using a Netgear WNR3500L router. I currently have the USB hard drive connected to the router via the Readyshare USB port but it is formatted as NTFS for Windows shared files. This router does not recognize HFS+ formatted hard drives in the USB port. When I move it to the iMac, I will back it up and then reformat it as HFS+. Since the router is about a year old and working fine, I would buy an Airport Extreme or Time Capsule if that is my only choice.
I don't normally turn off the iMac.
I would not want to allow access to any other device.
Since I am very new at Mac's, I would appreciate any help that any of you can offer me.

Topher Kessler,
Thanks for commenting to me.
My thumb drive is formatted as Fat 32 so your first paragraph explains what I am seeing.
You are correct that my existing router does not support HFS+. It is visible from my MAC and some file are read only.
The drive that I will be wanting to attach to the iMac would be formatted as HFS+ so it would not be accessible from my router.
So, if I setup sharing (If it is possible) and thern plugged in a USB 3.0 hard drive into my iMac, would it be accessible to my Macbook Pro? If it would not be, it looks like an Airport Extreme or a Time Capsule are my only options?
I see that a Netgear 4500 is Time Machine compatible. Any idea what that means? When I read pages 80 through 82, it appears to me that you format your drive to HFS+ and then eventually plug it into the router usb.

MB ram compatible with iMac?

Hi,
i have a MacBook1,1 and i did a ram upgrade (from 1 to 2), so i have 2x512M rams, my father have a iMac20" first gen with 512M ram.
Is it possible to put the ram from the MB into the iMac?
if it's only a slot free in iMac, is best to replace the existing ram with the one from the MB?
thanks
ciprian

Hi ciprian,
all Intel-Macs, with the exception of the Mac Pro, use the same 'kind' of RAM modules with the same specs.
So, yes, you can use the 2 modules in the iMac.
And yes, I would advise to put both in and put the one already in aside.
Have Fun

How do i get more RAM in my iMac G4 800?

I'd like to expand the RAM on my iMac G4 800. I read a few discussions and am not quite sure what I can do. Here is what I have and what I want to do:
Have: I have a iMac G4 800 with 512 in the J22 slot and 256 in the J20 slot. I am assuming the J20 slot is the one I can make changes to. Is that right?
Want: I'd like to add a 1 GB DRAM and make my memory 1.5 GB. I realize there is some debate about whether this machine can handle over 1 GB of main memory. So, can I do that?
Thanks

Hello and Welcome to Apple Discussions.
I'm afraid there is no debate: 1GB is the maximum on the 800MHz iMac.
Personally I don't believe that going from 768MB to 1GB is cost effective on this older Mac given that you will have to throw out a 256MB module.
On my iMac G4 J20 is the internal "Factory" slot which is difficult to access; this notation may be different on the 800MHz model.
Some tips to improve performance:
Quit Safari often; it suffers serious memory leaks that Apple doesn't seem in a hurry to fix and will gobble up your RAM.
Keep your hard disk nice and empty. Once you fill your hard disk above the 85% level you'll start to get fragmentation and the available space for virtual memory is not there.
Use a system maintenance application like MacJanitor (link).
Quit applications when you're not using them.
Have a look in Macintosh HD > Applications > Utilities > Activity Monitor. How much Free and Inactive RAM do you have? If the processor regularly being tasked to 100%? How many Page Outs do you have?

When I insert an audio CD into my iMac, it automatically starts playing

When I insert an audio CD into my iMac, it automatically starts playing, and I can't figure out why, nor how to stop this behavior. When I click in the upper right corner of my screen where it says "Finder", it shows the Finder as the only application running, and yet SOMETHING must be causing the CD to play. If it is an Extension that is being loaded, is it possible to terminate the Extensions one by one without restarting the computer to see which one is playing the CD?
Is the OS9.1 operating system supposed to automatically play audio CD's when they are inserted into the iMac? Or could it be an Extension that is doing it?And if so, why is no means provided to actually CONTROL the playing of the CD (such as a control panel with PLAY, STOP, SKIP, etc. buttons)?
On a PC, I can press Control/Alt/Delete to bring up the "Task List" that will show me ALL applications and processes currently running, and then terminate apps and processes one by one without having to restart the computer to see which one is playing the CD. Is there an equivalent way to display this information on an iMac that will show me which application or process or extension might be causing the audio CD to play, and allow me to terminate them one by one without restarting the computer until I can see which one is the "problem"?
Jerry

Hi, Jerry -
Welcome to Apple's Discussions.
Finder uses QuickTime in the background to do that, hence no specific app is shown in the Application menu (the far right item in the main menu bar) in addition to Finder.
To unset automatic playing of CDs (and DVDs) -
Open the QuickTime Settings control panel (Apple menu > Control Panels > QuickTime Settings).
In that control panel, select AutoPlay from the pulldown menu in the control panel. Uncheck both the items shown in the new window. Close the control panel.
No restart should be needed in order to make the change effective.
Doing this will also guard against the (now ancient) AutoPlay virus, which could still be lurking somewhere on the net.

Since upgrading to OSX 10.6.8, I am unable to use scp on a remote machine to copy files into my iMac.

Any suggestions?
However, I can use scp to copy files out from my iMac (10.6.8) .
I can ssh into the iMac OK.
I created a .profile in my iMac home directory with the single line "export TERM=xterm-color".
This makes a difference to how scp behaves when attempting to copy into the iMac, but it still fails.
Thanks in advance for any help. Peter R

Installing additional RAM into hp s5150t

I have a quad core s5150. I recently tried to add two additional RAM modules. I verified that I had purchased the correct RAM on curcial.com and by speaking with their reps. The computer would not take the RAM in any configuration. We tried seating the new RAM into the old modules one at a time and it still would not work. At last, the crucial rep told me to try and update the BIOS. Hard as I tried, for three hours, I was unable to find the BIOS update on the HP website despite looking where the HP video told me to look. There were lots of update options but no BIOS heading. The auto detect tool could not identify my computer for some reason. The HP Update tool installed with the machine said no updates were available.
I am wondering a few things, 1) Where can I find the BIOS update on the HP site? It is not in the list of updates on this page, where it is supposed to be:
http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?os=4063&lc=en&cc=us&dlc=en&sw_lang=&product=4002...
2. Is it possible there is a problem or conflict beacuse the machine shipped with Windows Vista and I updated it to Windows 7? Looking in the BIOS, the last update was May of 2009, long befoe Windows 7 was updated from the old VISTA files.
3. Any other reason you might know for the modules to not be working? We exchagned them for a fresh set already and still the same problem. They are clicking into place. Not sure what to try.

Thanks for your support, Jaco. I appreciate your input.

"Itunes can not connect to this Ipod. An unknown error occurred." I get this message when I plug my Ipod touch into my Imac. I have restored the Ipod and have the latest Itunes. I have tried different cables and a macbook.

I have an Ipod touch 8GB, an Imac and an apple laptop. I have had this Ipod for years and it has been synced at different times to my Imac and laptop. Recently the battery ran way down on my Ipod. I plugged it into my Imac. After it charge I had to restore it. After I restored it Itunes couldn't connect to it because, "An unknown error occurred". I tried to connect it to Itunes on my laptop and got the same error message. I have tried different USB cables. Since Itunes won't connect, I can't do another restore. I don't know what do try from here.
Some additional info that might be related to this. Just before this Ipod problem came up I crashed my hard disk on the Imac. I had to erase it and reload all my stuff (I was able to copy the contents to a hard drive connected to my laptop using the firewire - I couldn't use time machine because of the crashed HD.) My Imac has been restored to the latest Itunes - I am running OSX 10.6.8.

Thanks for the help Ricky.
I did put my iPod into DFU and iTunes recognized it in restore mode. After restore I am back where I was before - iTunes cannot connect because of an unknown error.
I have installed Jailbreak to see if I can bypass itunes but haven't succeeded. I can't get my computer to recopgnize the iPod as a device.
I'll take it to a Genius bar next time I am in the area of one. Until then I'll probably continue to try hacks to get it connected.

Installed airport card into my imac G4 flat panel and now it work

I purchased an airport card from Mac-pro as Apple does not sell them anymore. I installed it into my IMAC G4 flat panel as per the instructions. Now, when I turn on the computer the power light comes on, and the screen is black and it really isn't making any noise, as though it is not starting up. It was working just fine before I installed this card!!!! can anyone help??!?!?!?!?

The following Apple article provides the details of
installing an AirPort card in the Flat Panel iMac
G4s. You may want to double-check it to see if you
might have missed something in the the installation
process.
I installed the card properly, as per the instructions you forwarded to me. I did have some trouble getting the card to completly fit into place, one side seemed to go in easier than the other, but it did go in. Is there anyway to get this machine up and running again?

Hi!
I have a WD my book external hard drive plugged into my imac and I want to share it over my network with my apple tv. I went into system preferences > sharing, checked "file sharing" and added my external hard drive to the shared folder. So now it is listed in "shared folders" but under "users" everything is grayed out (it says "read and write" for "everyone" - but "read and write" is grayed out, and it doesn't let me add or subtract users). Now I can access all of the folders I shared from my imac except for the externalhard drive. What's going on?

Hi RRFS!,thanks for help.I forgot to tell that hard drive has 2 partitions 1:format :Mac OS Extended (Journaled) and that works properly,2:format:MS-DOS (FAT32) and when i "get info" for both :first has shering & permitions:You can read and write - with name and privilege, second has shaing & prermissions:You can read and write- without name and privilege

I have a late 2012 iMac and a late 2009 mac mini. I want to know if I can take the 8 GB of ram from the iMac and install it in my mac mini.

I have a late 2012 iMac and a late 2009 mac mini. I want to know if I can take the 8 GB of ram from the iMac and install it in my mac mini.
According to Cruicial my mac mini could use:
Module Size: 8GB Kit (4GBx2)
Package: 204-pin SODIMM
Feature: DDR3 PC3-8500
Specs: DDR3 PC3-8500 • CL=7 • Unbuffered • NON-ECC • DDR3-1066 • 1.35V • 512Meg x 64
Also According to Cruical my iMac uses:
Module Size: 8GB Kit (4GBx2)
Package: 204-pin SODIMM
Feature: DDR3 PC3-12800
Specs: DDR3 PC3-12800 • CL=11 • Unbuffered • NON-ECC • DDR3-1600 • 1.35V
I want to increase the ram in both computers.
So, can I put the iMac ram in my mac mini and then I'd only have to buy ram for my iMac? Naturally the ulitmate test will be when I actually install it, but having an expectation of success or failure will allow me to plan on what to spend money on.
Thanks,
Bear

Thanks for the responses. I probably wont even try as my priority is Ram for the mac mini. 2 is not enough. 8 for my imac is okay for now.
Somewhere I thought I'd heard that faster Ram would simply clock at the lower speed. It seems that I am incorrect.
Thanks,
Bear

RAM Memory for iMac 27' (Late 2012)

Hi,
I have read a lot of discussions about what's the best option to upgrae the RAM for the iMac 27' (Late 2012), but I really don't know what should I buy in terms of compatibility.
Kingston ? Corsair? ,etc...
I pretend to remove the memory that's on my iMac (2x4GB) and install new ones 4X8GB=32GB, so, my question is, which brand should I buy, and also what about the voltage(1.3, 1.5) and latency (CL7, CL9, CL10, CL11...)?
Thank's

If you will go to either OWC (macsales.com) or Crucial, their sites will help you determine what you need.
http://eshop.macsales.com/shop/apple/memory/iMac
Use OWC's instructions to find your model identifyer. Their RAM has been tested and is guaranteed.
I would not recommend cheap brands or Value RAM.

I made a Blurb book through Lightroom 5, on another computer, backed it up on an external hard drive and tried to import it into my imac. I got the picture files, but could not get the book I had worked on. How do I find my book?

I made a 'Blurb' book using Lightroom on a computer that was not mine. I backed up the book on an external hard drive and then tried to import the book into my imac. I wasn't able to retrieve my book. The photos I used for the book project are there, but the 45 page book I made is not there.
What do I need to do?

You would need to go to the computer containing the book.
Select the saved book in the Collection panel.
Go to Grid View [ G ] and select all the images [Cmd/Ctrl][A]
File>Export as Catalog and store on media you can use to transfer
Bring this catalog onto your computer
File>Import from another catalog and bring the transitory catalog into your master catalog.
It should bring the images, your collections (including your book) and other settings into your own catalog.
