Mac OS X 10.5 Leopard installation system requirements
http://support.apple.com/kb/TA24950
Leopard is no longer available at the Apple Store but may be available by calling Apple Phone Sales @ 1-800-MY-APPLE (1-800-692-7753).
If you can't obtain a retail install DVD from Apple, look on eBay or Google the installer part numbers to possibly find at an on-line store. Here's what to look for:
MB427Z/A Leopard 10.5.1 install DVD
MB576Z/A Leopard 10.5.4 install DVD
MB021Z/A Leopard 10.5.6 install DVD (single user)
MB022Z/A Leopard 10.5.6 install DVD (5-user family pack)

What is the best operating system i can run

Processor 2 GHZ Intel Core Duo Memory 2 GB 667 MHZ DDR2 SDRAM, currently running Version 10.4.11
<Title Edited by Host>

Just so you know, a Mac with an Intel processor is not a G-series Mac (i.e., yours isn't a G5).
"Best" depends upon what you need, though if you only have a Core Duo processor and not a Core 2 Duo you are limited to OSX 10.4.11-10.6.8. With your ocmputer I would grab a copy of Snow Leopard (10.6) before they really are all gone.
Apple no longer carries 10.6 in its stores or online. Telephone Apple to purchase a Snow Leopard disc. In the USA: (800) 676-2775 (contact information for other countries: http://support.apple.com/kb/HE57)
Alternatively you can buy from online retailers but expect to pay much more than the original price which is the price still charged by Apple

I have a Power Mac G4 1.25 Ghz 1 GIG Ram, what is the latest OS X I can run?

I have a Power Mac G4 1.25 Ghz 1 GIG Ram, what is the latest OS X I can run? I am currently running Jaquar. Where can you obtain older versions of OS X?

Actually you can run up to Leopard 10.5. It requires a G4 867mHz processor so you are comforatbly over the minimum specs.
That said, I offer two caveats regarding Leopard that may make Tiger 10.4 more appealing:
1) Leopard may want more than 1G RAM. With currently available modules, you can take your Max RAM to 2GB. You can install up to 2GB RAM.
2) If you don't have a video card that supports Core Image, things can be choppy. My 1.25 G4 is a tad sluggish with Leo because I have the original ATI Radeon 9000 64MB VRAM vid card. If you have a Redeon 9600 or higher, you likely have Core Image Support. Use System Profiler to Identify your exact video card. SP is in Applications > Utilities. Select "Graphics/Displays" from SP's "Contents" pane on the left to view the specs of your card in the main pane. It wil tell you if Core Image is supported.
If you can get Leo running fine, it's better in that many programs no longer support 10.4.
Looks like yo uare in the Continental US. Call Apple at 800-MY-APPLE and ask for an operating system specialist. Tell them you need 10.5 to support new hardware. I bought that way in March, and it sounded like they wre going to keep Leo in stock for a whie because of the larger number of olders Macs that can;t run Snow Leopard or Lion.
Be very, very careful of Mac OS software on auction sites. I've seen too many that were improperly described and would not work. Likewise the gray Leopard install disk that came packed with another Mac model won't work.
I just checked--OWC does not list any Apple System software at this time.

G3 blueberry clamshell - what is the highest operating system it will run

I have a G3 Blueberry clamshell that has OS 8.6, 160 MB built in memory. What is the highest operating system this can be upgraded to?

Before you install OS X make sure you check the ibook's firmware - chances are it hasn't been updated. You should be running version boot rom version 4.1.7. You can check this out in your system profiler under production information. I think you have to be running OS9.1 or OS9.2 to do this. Once you have installed OS X you won't be able to do the firmware update.

Officially your upgrade path is the Mac Box Set - http://store.apple.com/us/product/MC581Z/A
But if you just want to update the OS, then the Snow Leopard disk will not mind that you're on Tiger. Remember to take a full backup beforehand - preferably a clone of the disk (Carbon Copy Cloner, SuperDuper, or Disk Utility will do this) because I think SL will fully blank the disk so you'll need the clone to do a User Migration from after the install completes.
The Box Set is the better deal if you want iLife and iWork updated too.

What is the newest operating system I can upgrade to with an IMAC (maximum 4gb memory) purchased in late 2007

I have an IMAC (purchased in late 2007) that has been upgraded to the maximum memory of 4GB. Current operating system is 10.6.8.
How much farther can I upgrade the operating system?

The IMAC was upgraded by a local computer service store because we have dial up. The person who did the upgrade said I couldn't upgrade any further because the IMAC would run to slow. Here is what I have now.
Model Name: iMac
Model Identifier: iMac7,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.4 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 4 MB

Serial Number (system): W87482Y9X88
Hardware UUID: 00000000-0000-1000-8000-001B63BE8AEA
Any thoughts on realistic upgrade potential? I need to do something as my current Safari version (5.1.10) is not working properly on some important web sites.
Thanks!

What are the normal operating temps for a G5 Quad Core Power Mac Tower?

I asked this within another thread but I am afraid it will get buried and think it deserves its own item.
I just downloaded Temperature Monitor and have been looking at the data. I have no idea how to interpret the figures and there are no listings of specified upper and lower limits even though there is an area where those numbers should go.
The numbers are constantly in flux, going up and down a degree or two but here is a recent example from a screenshot taken while I was running WORD (but not working on any document), Terminal, Apple Mail, Firefox (two windows open), Temperature Monitor, Preview, Dashboard and Finder:
Air Tunnel 99.5 degrees F
Air Tunnel Heatsink 92.8 degrees F
CPU A Core 1 Diode 107.5 degrees F
CPU A Core 2 Diode 107.8 degrees F
CPU B Core 1 Diode 108.0 degrees F
CPU B Core 2 Diode 111.5 degrees F
Drive Bay 87.8 degrees F
Graphics processor chip 131.0 degrees F
Main Logic Board Air Inlet --- (this is always missing)
Main Logic Board Backside 108.7 degrees F
Memory Controller Diode 133.9 degrees F
SMART Disk WDC WD2500JS-41M.... 104.0 degrees F.
The icon for the program, in the dock, gives me an ever changing number that is perhaps an overall reading - an average. Right now the number is 106.4 degrees F (taken some minutes after the screenshot providing the above data). Always in flux.
Do any of these temps look alarming? And HOW and WHERE do I find out what the temperatures SHOULD be?
PS I have APPLE RAM.

If you want to find out whether a sensor value is within normal limits, please select the menu item Window > Show Overview (or press Apple+1) and look for the limits in the third and fourth column of the sensor table. They contain the known official limits Apple has specified for readings acquired at the given sensor locations. If no limit is given in the table, this either means that it does not make sense to specify a limit for this particular sensor (e.g. the battery capacity should not have limits), or Apple hasn't published any specifications for this sensor.
Note that all up-to-date Macintosh models automatically shut down or enter sleep mode if one of the readings exceeds a critical limit. For this reason it is impossible that your computer can be damaged in an overtemperature condition.

There are also notes on the two version for the G5 Quad.

You need iTunes version 11 for iOS 7.
iTunes version 11 requires OS X 10.6.8 or later...
Click on the Apple icon.. Top left in Finder...

You can check to see if yours meets the system requirements for Snow Leopard - that would be the highest; Lion will not run on your machine.
Please note that the minimum 1 GB RAM is a minimum - 2 GB would be better.

You can buy it at the Apple Store, other online resellers, or ebay (but be careful there to only bid on a new retail shrinkwrapped package to you don't get suckered into a used install disk which won't work on other machines).

I have just upgraded my Ipad2 to the latest operating system and on restarting it is some foreign language and is asking for the sim card number when I don't have a sim card. What do I do?
