Upgrade memory on a 800 MHz PowerPC G4
I believe I can add more PC133 SDRAM memory to my mac, but have been advised that not all memory works, how do I know what works and what does not?
If you can use this link, here is a really good price...

Please advise, the last thing I want to do is buy the wrong memory and install something that doesn't work. THANKS!

Hello,
1. There are two slots as shown in the photos below:
The left one being the SODIMM "User" slot and the right image showing the DIMM "Factory" slot.
When Apple published the maximum RAM for the iMac 800MHz it was based on the fact that in both DIMM and SODIMM form 512Mb was the largest capacity on the market hence 2 x 512Mb = 1Gb max. If it is now possible to get a 1Gb PC133 DIMM then theoretically 1.5Gb could be the max but I have heard nothing to confirm that this actually works in an iMac G4.
Crucial always stick to Apple's specs and hence 1024Mb.
2. I suspect that you have 1 x 256Mb PC133 168pin DIMM (factory) and 1 x 256Mb PC133 144pin SODIMM (later upgrade). You can check this by looking at the contents of J13/J14 memory slots in  Apple Menu > About This Mac > More Info... > Hardware/Memory

Hi, I have recently got myself a second hand computer MAC OS X Version 10.4.11,Processor 800 MHz PowerPC G4. Have only used windows before. Unfortunately I managed to uninstall Adobe but now can't seem to reinstall as this an older computer

Hi, I have recently got myself a second hand computer MAC OS X Version 10.4.11,Processor 800 MHz PowerPC G4. Have only used windows before. Unfortunately I managed to uninstall Adobe but now can't seem to reinstall as this an older computer and is not compatible with the new versions. Sorry to sound thick but really have never used Apple before. Would really appreciate any help at all. Thanks..

Windows or apple it makes no difference, if you don't have the install discs you can't install.
Did you buy the machine with Adobe (you don't say what adobe program you're talking about) installed? If so the vendor should have given you the discs or else it's technically a pirated copy. If you're talking about acrobat (which is free) then you should be able to find older versions on the adobe site.

10.4.11 - help upgrading memory

Hello!
I have a 2006 imac (I believe it is considered early, but I purchased it in May 2006). I've always had one memory slot empty and 1GB of memory in the other. This past May my hard drive crashed and I replaced it, and now I'm starting to notice that it has been running slowly, especially when using iphoto, and so I would like to add 1GB of memory to the empty slot. I tried purchasing memory from the apple store, but they no longer have memory for my model and I'm not really sure how to find the correct memory for my computer. Here is the overview:
Model Name: iMac
Model Identifier: iMac4,1
Processor Name: Intel Core Duo
Processor Speed: 1.83 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache (per processor): 2 MB
Memory: 1 GB
Bus Speed: 667 MHz
Boot ROM Version: IM41.0055.B08
SMC Version: 1.1f5
Serial Number: QP61609WV4M
Could someone please tell me what memory I need and where I can find it? Any help will be greatly appreciated!!
Also - I'm interested in upgrading my OS to leopard or snow leopard - with the 2GB of memory will it run well on my computer? My hard drive is 350 GB and I'm only using 80 GB. If so, can I just purchase the $29 disc or do I have to purchase the $169 pack?
Thank you!

any experience with that site?
Limited experience with them, & likely their IntelMac RAM is OK.
The guy at the store told me it is closest in quality to memory directly from Apple.
Of the RAM I've had go bad, all but one stick was original Apple RAM, to be fair when they come out with new models they're generally using the newest/latest/fastest at that point, & manufacturing may not have production down pat until later.
will anything on my computer be wiped out, or is it an easy install?
No, SL defaults to what we used to call Archive & Install, which preserves all your stuff, just new OS & new of some Apple Apps.
Just be sure to Open Disk Utility & Verify the Drive first, (not Verify Permissions).
I'm debating on whether to upgrade it or not because I love tiger, I'm just frustrated that I cannot buy a new ipod, an ipad, Adobe CS5 or the magic mouse because none of those things will run on Tiger.
Yep, if you need any of those things, SL is a must then, but I prefer Tiger myself & have no need of any of those.

IMac help upgrading 10.2.8 to 10.3

I am a new owner of a Ruby iMac with 400mhz, 192mb Ram, 10gb HD, that is currently running 10.2.8... I also have a new set of retail 10.3.5 discs to do a clean install on this iMac, so I can set it up the way I want to set it up...
My problem begins with me as an old PC guy, but a real novice on Macs... When I booted the iMac to the CD, the install begins, then stops with a statement that I need to do a firmware upgrade to install OS X... This confuses me, since it is already running OS X...
Can anyone please advise me on what to do, as I cannot find a firmware update such that the wording of the download matches my situation... As further information, apparently this Mac is only running OS 10.2.8 and has NO OS 9.x to run in classic mode...
Please Help...
Dan Birchett

I have my OS X (10.2.8) installation working again... The only thing I wanted to do is still the same as before, and that is to raise my just purchased iMac (OS X 10.2.8) to the same OS as my very recently purchased iBook (OS X 10.3.9)... I have the OS X 10.3.5 retail discs in my hand, and the upgrade to 10.3.9 is free on this Apple site... By the way, neither of them have any OS 9 installation on them...
So I can understand, (remember I am a PC guy learning MAC) are you saying to dump my now working 10.2.8 to some level of OS 9 to upgrade the firmware (BootROM) to 4.1.9 from the current 3.0.3, then install back the OS X installation that I want to do???
Also, what about the existing application software on the MAC that I do not want to loose??? Is there a backup or copy procedure that I can do to retain this software???
Sorry for all the questions, but the MAC world is very different from the PC world...

IMac mid 2007, 2.4 Ghz, 800 MHz... Grey screen only, running OS 10.5.8. Tried reinstalling, restoring, and resetting but to no avail. Possible to install OS 10.6 and get it to boot?

Try to boot and only getGrey screen, sometimes with the globe f
Asking, sometimes not.
I am running OS 10.5.8. Tried reinstalling, restoring, and resetting both with installation disc and without, but to no avail.
I recently upgraded from 1GB memory to 4 GB. It ran great for a couple of weeks, when I eventually powered it off, it would not come back. With installation disc, I did get to the utilities and tried repair and even reinstall original OS (several updates down from 10.5.8). At one point, I was able to restore a previous session, but it only lasted for about 3 days until I powered it off again, then back to square 1. I have verified the Macintosh HD disc and repaired it, I have reset everything I can find that might need resetting... Still nothing.
SO, is it toast, or is it possible to install OS 10.6 and get it to boot?

Erase the drive then install OS X:
Drive Partition and Format
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
If you are preparing an external or a non-startup drive, then open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
If this doesn't work then the drive is probably bad or some of the new RAM you installed is marginally defective.

Mac os x Version 10.5.8 Dual 800 MHz PowerPC G4 2 MB l3 cache per proscessor Memory 1 GB SDRAM

Hello i just wondering anyone who have one old like that my powerpc do have download from program for old i know that only up to 10.5.8 i just want know if have some like i need downlaod for for example FCP, After Effect, CS3 something i need want know if do have i need somethihng if if no more finish expire that that ok i am understnad that

Attempted to download 4.o version, it has a big Ø sign through it and won't start... I'm running Mac OS X 10.4.11 Processor 800 MHz PowerPC G4 512 MB SDRAM

When I started my old version of Firefox (3.something) I got a message recommending that I install a new version 4.0. When I downloaded it and opened Firefox 4.0.dmg, it had a Ø sign through the icon. When I drag it to my applications folder, it will not start. I get the following message "You cannot open the application "Firefox.app" because it si not supported on this system." I cannot find the previous version to re-install it, so I'm completely without Firefox.

Firefox 4 requires at least OS X 10.5 and an Intel Mac. There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox
If you prefer, you can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html
Mozilla are working to prevent Mac users with non-compatible systems from getting the notification about Firefox 4, and also not displaying the "Download Firefox 4" button on http://www.mozilla.com

AirPort with early Imac PowerPC G4 800 MHz

I have an early model flat panel iMac, (with no AirPort card), which I intend to keep using for some years yet - alongside a new iMac or MacBook I plan to get later this year.
Now I have just bought an Airport Extreme and an Airport Express (thru Apple Store).
I thought to hook the Extreme via Ethernet to the iMac, and the Express to my D-Link ADSL Router.
As soon as I tell the Extreme to use Ethernet to connect to the iMac, well that seems to kill the wireless side of things in the Extreme, so it can't talk with the Express.
I have looked thru Apple / Support / Discussions, searched on << AirPort Express AND AirPort Extreme AND 800 MHz PowerPC G4 Imac >> with no success. Even artnum=107454 did not seem to help.
Help please - is it possible to get Airport running with this old imac, with no AirPort card, with the Airport items I have just bought? Is my best bet to try and pick up an early Airport card, (before APExtreme card came out)?
RipVanWinkle

I've spent all day trying to get that "trick" to work and it kept failing giving me the message:
+The Installer could not validate the contents of the Base System package. Contact the software manufacturer for assitance+
I lost all the contents of my hard drive (no prob I backup externally), then later the HD failed to appear at all as a bootable or startup option, then when trying to restart I would get the black root screen ...
(my extetnal is a bootable backup)
Fine, I pulled out Tiger, clean installed. Turned right back around and tried the workaround again. I'm typing this after getting the same error message for the third time. I'm sitting right here watching Tiger install the Base System, so why can't Leopard find it? Is there something I can do on the firmware page to help it find the BS when I'm also convincing my computer that it's actually an 867?
I didn't know I wasn't supposed to be able to use Leopard on my 2002 Dual 800 Quicksilver when I bought it. I wish I did. I can't get the installer to work. So if anyone has any ideas or solutions?
I'm about to just hang with Tiger 'cause I'm not buying a new computer. I can't keep installing Tiger then Leopard, Tiger then Leopard. I need to use my computer.

Upgrading Imac g4 flat panel 800 mhz

I decided to post this information here because a lot of people are wondering how do i go about upgrading a macintosh imac g4 A.K.A Ilamp as it is known in the mac community.
Well this tutorial will walk you through a basic configuration that i recently did that seem's to work very well.
Item's you will need.
1. mac os x tiger 10.4
2. A external cd-rom/dvd-rom
3. a 7200 rpm 250 gig hard drive
4. 1 stick 512 meg's pc133 sdram
5. 1 stick 512 meg's pc133 so-dimm for laptop memory slot at base of imac
6. a new and faster dvd-drive (i used a light scribe)
So after installing all of the hardware in my imac.
I ran into a problem it has to do with the imac firmware update for mac os x tiger to be installed..
The built in dvd-drive wouldn't eject i thought it was a bad drive come to find out the drive won't eject without a os on the machine.
so i needed a external usb/firewire cd/dvd-drive to boot the tiger installation and install tiger well after installing tiger from the external cd/dvd-drive i noticed the drive ejected and worked fine but i knew that if i wanted to burn anything i would need to install a new drive.
so i purchased a new lightscribe drive.
installed it.
after that my system specs are
Imac g4 800 mhz
1 gig ram
250 gig hard drive
52x lightscribe DVD
running mac os x 10.4.11
it really just depends on how much you want to spend to upgrade i found that this configuration works great for media streaming.

what kind of HD did you get for it? I'm still waiting on buying the right one. version that can be installed in these older lamp macs of ours. I know it needs to be an IDE drive. Is that the same as an ATA drive? i know that the new systems now are SATA.i happened to call apple one day and they said that my G4 flat panel uses ATA-6 drives. i do a search for those drives on newegg.com and all that comes up are notebook drives. so what kind of HD do i get?

Can anyone help me with upgrading memory in my older iMac? I currently on have 1gb of memory so as you can imagine my machine is quite slow.

Can anyone help me with upgrading memory in my older iMac? I currently only have 1gb of memory so as you can imagine my machine is quite slow. I check in my system profiler and it shows I do have a memory slot open. It is using a DDR2 and I was told that the latest are DDR3 and I need to find out if I can run that on my model number. This info came from a tech guy at best buy.

That is what I needed. You can upgrade to a maximum of 6gb of ram and need the following type:
200-pin PC2-6400 (800MHz) DDR2 SO-DIMM. You can easily find it online, here is an example: http://eshop.macsales.com/shop/memory/iMac/Intel_Core_2_Duo_PC2-6400

Video: Software Final Cut Pro X 10.0.8
I use the imac mainly for editing Video which when doing so it has reached temperatures of near to 60° C which causes the program to become unstable and needs to be cooled down to operate correctly.
An Apple technician (by phone) advised me to download an smcfancontrol. This allows each individual fan to increase speed and also advises the current temperature at °C. The smcfancontrol has been downloaded but this has not resolved the problem. By increasing the speed of the fan more heat is generated and creates additional noise.
I have since taken the iMac to an Apple Store for examination as suggested by APPLECARE when the fans were found to be working correctly. An Apple Store technician carried out a test, but not whilst working under the pressure of FINAL CUT PRO when the iMac generates a high temperature.
The Temperature Specification for this model is
Operating Temperature 20 °c to 35°C
Storage Temp.47°c
Clearly the temperature my iMac is operating at is excessive and could cause the computer to break down prematurely. Has anyone experienced this problem.

When was the last time you cleaned/vacuumed out all of your iMac's vents, slots and ports.
You need to do this with the iMac powered down, disconnected from power and everything disconnected.
Lay your iMac, screen down, on a soft surface, like a heavy towel. Use a small electronics vac, or portable or full size vac with hose and a crevice tool attachment and carefully and slowly vacuum every vent, slot and port on your iMac.
Then reconnect everything up, power up and download and install iStat Pro. Start working, then report the temps of your iMac after this has been done.
When using SMCFan Control, it is important not to run the fans at too high an RPM. This doesn't generate heat on its own, but will suck in more dust, lint and dirt into your iMac, and that will be the cause of additonal increases in heat.
I run my fans in the range of 1400-1600 RPMs. You can go as high as 1800 RPMs but it is important to keep the RPM range below either 1800 or below 2000 RPMs.
I, also, run a very small desktop fan pointed toward the upper back of my iMac to keep temps down even further.

The latest version of Adobe FlashPlayer can be obtained from here:
http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFl ash
You can check here what version of Flash player you actually have installed: http://kb2.adobe.com/cps/155/tn_15507.html
You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS.
You should first uninstall any previous version of Flash Player, using the uninstaller from here (make sure you use the correct one!):
http://kb2.adobe.com/cps/909/cpsid_90906.html
and also that you follow the instructions closely, such as closing ALL applications first before installing. You must also carry out a permission repair after installing anything from Adobe.

Tiger upgrade for an 800 Mhz iMac G4 running 10.2.8

When looking for the upgrade and/or install DVD's to upgrade to Tiger OS X 10.4 on an 800 Mhz G4 iMac currently running on 10.2.8, are there specific versions to look for? I have seen some for sale online that say they are good for the G4, G5, etc. but also say OS X 10.3 is required for the upgrade. Is there a way to upgrade from 10.2 to Tiger 10.4?
Thanks.

How much RAM do you have in that machine? You may have enough for running 10.2 or 10.3 just fine, but the real-world requirements for 10.4 are a little higher. You may be disappointed with the performance if you don't have at least 1GB.
Also, how much free space do you have on the hard drive? The stock hard drives in those vintage iMac's weren't very fast or large. You might consider installing a new OS version on a bootable external FW drive, that way you can keep your existing system on the internal and boot from either, you can go back to the 10.2.8 system as needed.
Do you have any third-party software or hardware, (printer/scanner/etc) that will not work in 10.4? Those may require upgrading to new versions/drivers, if still available.

What Speed Memory for a 3.06 Ghz 24" iMac? 800 Mhz or 1.066 Ghz?

What speed memory should I have in my iMac 24" 3.06 Ghz Intel Core 2 Duo?
It seems to have come with 800 Mhz memory, but the Bus Speed is 1.07 Ghz.
Shouldn't it be able to use 1.066 Ghz memory??? Or is it not really up to 1.07 Ghz? The serial number is: QP8390YD0KM.
Thanks, Jim.

Some of the previous iMac models had bus speeds that did not match the RAM speed, by design.
You should use this OWC web store page.
http://eshop.macsales.com/shop/apple/memory/iMac
Just click on your specific iMac model and read the specs on one of the compatible RAM modules.
You can also find your iMac model here
