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.

    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

    MB021Z/A  Leopard 10.5.6 install DVD (single user)

    Hello USME,
    'Tis a common problem on old Macs.
    Do as Allan says: open the door and blow out all the dust bunnies. Canned air from Wal-Mart or Radio Shack can be handy (though sort of expensive) especially for blowing through the back of the power supply. A cool Mac is a happy Mac.
    Be sure your Mac can breathe. The air intake is on the bottom of the case, so be sure a deep pile rug or too many papers on your desk are not blocking the air supply.
    Feel the power supply and the processor with your hand. They should be warm but not hot; if you have to move your hand away, that's too hot!
    Check the fan on the power supply, and on the processor if it has one. Take a flashlight and peer in the back of the (Mac) case through  the grille; make sure the fan is turning. If it's not, the power supply won't work for long.
    Fans are not considered serviceable, though they will succumb to mechanics of determination. A CPU fan is easy and straightforward.
    A fan replacement will not cure an already damaged power supply; the PS may already be done for. Used power supplies for a DA are hard to come by, and not especially cheap when found (c.$50). An entire  working DA or Quicksilver may often be found for under $100 on eBay, and swapping in your HD is easy and simple... this might be cheaper and more expeditious than repairing an expired DA. Replacing a power supply is fairly easy, but it's a nuisance and requires a 2mm Allen head wrench in addition to the usual #2 Phillips head screwdriver.
    In my experience, power supplies and CPUs are about equally likely to fail. There are a few other possibilities, but they are not nearly so common.
    Good luck!... Jon

    I have a Mac Pro Dual Core, 3 Ghz, that I purchased in the Spring of 2007.  What is the latest OS that i can upgrade to?  And is that OS compatible with Logic 10?

    Logic Pro 10 requires OSX 10.8.4, which is not officially supported on your Mac Pro (must be Early 2008).
    There are, however, unofficial workarounds to install 10.8 on those older models that you can search for on Google.

  • I have a power mac G4. OS 10.4.11 I just got a new iphone G3S what will it take to get my phone to sync with itunes?

    I have a power mac G4 OS 10.4.11  I just purchased a new iphone G3S how can I get it to sync to itunes? When I try I get a message that I need OS 10.5  can I load 10.5 on it? can I still buy 10.5 ?
    CPU speed 800mhz
    memory 512

    Don't fret.
    Find a copy of Leopard (call Apple Customer Support and tell them that you have a machine that can't run Snow Leopard).
    You could also go to eBay.
    After that, install it:

    Leopard will run fine in a 800 MHz machine.

  • Power Mac Dual 1.8 Ghz: How do I connect to wireless network?

    HELP!!!
    I have this Power Mac Dual 1.8 Ghz with 10.4.11 OS. I used to use wire cable to connect the internet, but now the place I rent recently only provides wireless network. I was able to connect wireless network with my Windows Laptop.
    Question: How do I connect my Dual 1.8 OS 10.4.11 with wireless network? I only see Internal Modern, Built-in Ethernet and Build-in FireWire options.

    You can go the OWM route and get the airport extreme card and antenna

    Google the part numbers for more vender choices,
    Or, you need to get a PCI WiFi card and antenna. BDAqua or Japamac have posted alternatives which are actually a little cheaper than the Apple parts.
    The third alternative is a USB-based wireless adapter.

    I have a Power Mac G5 1.8 GHz Dual that came with a nVIDIA GeForce FX 5200 64 MB graphics card.
    QUESTION:
    Has anyone here upgraded the Graphics Card ( nVIDIA GeForce FX 5200 64 MB ) from their "Power Mac G5 1.8 GHz Dual"?
    If yes, how was your experience doing this? Do you like your new graphics card?
    Which 3 cards would be good upgrades on this system?
    I am looking for a little more graphics power.

    Thanks for the reply Edwin.
    The ATI X800 XT is a nice card. I little high on price, but it is awesome.
    What are the best reputable places to buy cards like this at the best prices possible?

  • I use Apple TV's screen saver with a file in my photo library.  If I install newest update - will that change anything with my using this favorite feature?  I have just under 4000 photos in that file.  What is the total # of photos it can utilize?

    I use Apple TV's screen saver with a file in my photo library.  I believe it is first generation or second Apple TV - not the newest one.
    If I install newest update - will that change anything with my using this, my favorite feature?  I have just under 4000 photos in that file. 
    And, what is the total # of photos it can utilize?  If I keep adding photos - is there a limit to the # it will utilize?

    Thank you Alan and  know you are right. I really can do all I need with my netbook and ereader and do not need the ipad. I think I just wanted something new and felt I may enjoy using it a lttle more than the netook. But it would be a waste just to buy one when I donlt acutally need it  And, donl't think it is worth the extra money for me the get the 4g wireless capability since I doubt I would really need it often.
    I may treat myself to the Ipad for the color, touchpad and fun to use but it is very expensive considering how little it will do for me no more than the things I want it for. It woudl be and expensive luxuray, I can do without. I actually  need t learn how to use more of the function avaiable first.  Maybe I should take up playing games and learning to take digital pictures so I can at least load them. If I could learn to do that and take a decent picture, I could start selling back all the "stuff" I have purchased on ebay. haha - I do have a nice doll collection, I would like to sell. I just do not have room for anything else. That was the primary purpose for the Kindle Ereader I bought and enjoy so much,
    But, I will hold onto the thought for a while and see how it goes and what other comments I get, If I think I cannot live without it, then I will have to rethink which one to buy, I coud get the 32 g if I did not have to pay for the 4g wireless. And, if I knew I could get help to teach me how to use and enjoy all the functions, I would give it more serious consideration. My granddaugther got one for Christmas and that was what got me interested in it. I love the size of the screen and it had good color and was fast. She even had an application where she could write her notes and it would convert into typed words. That was a neat feature, If you could print it?
    But thanks again for your comments and I will check later to see I get any other feedback.
    Sunny:)
