I wish to upgrade my 2007 iMac. I need to get to Leopard or Snow Leopard if possible. Here is my hardware currently:

 

Model Name:          iMac

  Model Identifier:          iMac5,1

  Processor Name:          Intel Core 2 Duo

  Processor Speed:          2 GHz

  Number Of Processors:          1

  Total Number Of Cores:          2

  L2 Cache (per processor):          4 MB

  Memory:          1 GB

  Bus Speed:          667 MHz

 

Any help would be appreciated.


iMac, Mac OS X (10.4.11)

    Buy the retail Snow Leopard DVD at your local Apple retailer or from the Online Store - $29.00. I suggest that you also put more RAM in your machine. You can install up to two - 200-pin PC2-5300 (667MHz) DDR2 SO-DIMMs each 2 GBs. This would provide 4 GBs of installed RAM. However, your model is only able to use 3 GBs. But this is an improvement over the 1 GB you now have.

    thanks, a correction is needed, my iMac is a late 2006. I installed only one 2 GB Ramm SO-Dimm and the Snow Leopard. I read that 2.5 GB would be more than enough RAMM. It is working but when I watch video the screen will freeze. Also, the dock icons have moved off my screen to a 'screen' to the right of my monitor. I have my tv connected by a cable that allows me to watch videos by sliding the Safari screen over onto the tv. The dock is there when I turn on the tv! Also, the bottom right corner of my desktop screen has an Apple background superimposed over the bottom 1/8th of my desktop extending onto the tv. Convoluted explanation but I had to move my dock to the left of my screen. I have read that maybe freezing is from dust buildup in the machine, causing the it to heat up. Does the machine work extra hard on streaming movies? I also read that perhaps equalizing the RAMM memory slots may be optimal. Any help would be appreciated. IS it true that Macs prove their worth by lasting much longer than PCs? I'm surprised I'm still able to use this after 5 1/2 years.

    Do as Kappy says and look into purchasing and installing the extra RAM to get you to 4 GBs

    That is really the working minimum RAM needed for OS X 10.6 Snow Leopard to do it stuff.

    iMac memory really needs to be installed in balanced pairs.

    Plus OS X like this configuration of RAM much better.

    So (2) 2 GBs sticks would be needed.

    Video streaming or video playing from the iMac is, definitely, more CPU and GPU intensive.

    To keep the dust out of your iMac, you need to power it down, unplug everything including the main power cable, rest your iMac on something soft and orient to be able to get to all of the venting areas.

    Using either a small special electronic/computer vaccuum or a vaccuum with a seperate hose and small brush or crevice attachment, vacuum all of the intake and exhaust venting on your iMac.

    Do this slow and carefully to get as much of the dust/lint buildup as much as possible.

    And do it slow so you don't scratch or damage your iMac's case.

    Should be doing this every three to six months. At the very least, once a year!

    Every Mac I ever had always had dust and lint in them.

    Getting this stuff out of your iMac will allow it to run cooler and more eficiently and, hopefully, eliminate any types of overheating or freezing of your iMac.

    If your the type that spends the money on a computer with hopes of getting, at least 4-6 years of service out of it, then yes, Macs do have a longer longevity cycle. If your iMac does everything you want it to or expect it to do, you may want to keep it up and running longer.

    Prior to purchasing my  "newer" 2009, 27 inch screen iMac, I worked for almost 10 years with a 2003 PowerMac G4 tower that served me and my needs very well.

    So, depending on what you use and need your iMac to do, you could have this longer than 5 years.

    thanks, I'll get the other RAMM and vacuum out that suff. Never did it so its probably got some junk in it. I want to load Lion or is that not necessary? I was thinking that the most recent is best but coming to think that is not always true by what I read.

     

    Thanks again

    I really think loading Lion onto this old an iMac will only slow the performance of your iMac down.

    Best to just install Snow Leopard and be happy with the results.

    Good Luck!

    It would appear that as of today, it's not even possible. Both Lion and Snow Leopard have been withdrawn from all Apple sources.

    You can find Snow Leopard, at a higher retail price, at Amazon.

    You could still ry and call 1-800-MYAPPLE and ask for retail software sales and see if they still have retail copies left of the Snow Leopard DVD for the original $29 OEM USD price.

    Good Luck!

    Luckily, I just bought Snow Leopard! Good timing, huh?

    GOOD ONE!!!!!

    Good Luck and have fun on Snow Leopard!

    Should run nice on your year iMac.
