Can Lion be installed on an iMac with a Dual Core processor?

I have an older iMac, model iMac4,1 with an Intel 2.0 GHz Core Duo Processor, 2 GBytes of 667 MHz DDR2 SDRAM. It is currently running Mac OS X version 10.6.8 and works very well.
I've seen conflicting information about the system requirements for upgrading to Lion. One spec says it must be a Core 2 Duo Processor. I want to see if I'm asking for trouble to try the upgrade. System is fully backed up with Time Machine.

Thanks Allan, for the quick and short answer. I've been reading other posts (should have done that first) and there are good reasons why it won't work. Best one is that the Core Duo is a 32 bit processor while the later ones are all 64 bit processors. Some have actually upgraded to the Core 2 Duo, but have not been successful in installing Lion on the internal drive.
I have a MacBook Pro running Lion and that is good for now. May try to sell my iMac, although it is a very good computer!

How do I upgrade OS X 10.5.8 on my iMac with Intel duo core processor

I have an iMac 24" with 2,16 Ghz Intel Core Duo processor and 2Gb 667 Mhz DDR2 SDRAM running on OS X 10.5.8 to Lion?
I know I have to upgrade first to snowleopard???
If so SnowLeopard is not available in the iCentres etc.
What to do??
Brgds,
Nils

Your iMac is a Core 2 Duo not a Core Duo according to this http://www.everymac.com/systems/apple/imac/stats/imac-core-2-duo-2.16-24-inch-sp ecs.html
Which is good since the specifications for OSX Lion require a Core 2 Duo as minimum processor:
Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
2GB of memory
OS X v10.6.6 or later (v10.6.8 recommended)
7GB of available space
Some features require an Apple ID; terms apply.
Some features require a compatible Internet service provider; fees may apply.
The road to OSX Lion requires you to have OSX Snow Leopard before which can be bought from Apples Online Store http://store.apple.com/us/product/MC573Z/A?fnode=MTY1NDAzOA but is not avaiable as a download.
After installation of OSX Snow Leopard and installation of neccessary updates to it you can then use the Mac App Store to buy OSX Lion and install it.

For OSX Lion an upgrade of your RAM to 4GB might be advisable.

Turning on Virtualization in Compaq/HP Presario C500 with Dual Core processor

Hoping someone can help me out.
Running a Compaq Presario C500 laptop with the Dual Core processor. Intel's site says the processor supports virtualization.
However, in the F.24 A Phoenix BIOS setup (pressing F10 on Startup), there's no option to turn on Intel Virtualization Technology on any of the Tabs. Tried downgrading the BIOS to F.14A -- as the description says; "Adds item to Setup utility (F10) to enable/disable Intel Processor Virtualization Technology."
However, when I startup, press F10 -- there's no option for turning this on.
Is there another place to go -- other than the F10 setup area of the BIOS -- to turn on Virtualization Technology?
If an expert out there can help, it would be very appreciated!

Did you actually download the identification utility and run the tool?

Problem with dual core processors: 50% ressources are not used.

Hello all,
I have noticed, that the java app cannot get normally more than 50% of the system ressources. I use different threads in my application, but the app still does't achieve 100% of system power. Max 50-60%.
If I run two processes, I get 100%, but I can't share memory space between this two process. Or I can?
What is the best way to write an application, that can use 100%, in other words, full power of dual core processors.
Thanks in advance.

Try thread.setPriority() method. I am making guess
and any comments
from experts on this method will be highly
acknowledged.Yeah. Don't do that, it's a bad idea.
Back to the original post, there are two reasons this can be happening.
1) Your code is not efficient multi-threading wise. If you are for example running two thread that are in theory parallel but in actual fact provide linear execution so that one is almost blocked by the other then multiple threads and multiple cores will underutilized. It's hard to speculate further on this without seeing your code.
2) The OS. First of all there is the issue of how the oS shares up the processor between processes. This varies and may or may not be configurable. The bottom line on this point is that your OS may be capping the utilization of the processor by process. Again there's not enough information give by you to expand on this point. The second OS issue regards how the OS deals with multi-core. Just because you have a multicore processor does not mean that your OS automatically can take advantage of it.

Can Lion be installed on a 2006 plastic body iMac?

My 2006 iMac has a 2.33 GHz Intel Core 2 Duo processor with 3 GB 667 MHz DDR2 SDRAM, the absolute limit. Can Lion be installed on such a machine, or should I be looking to buy a 2011 iMac? Thanks.

Can it be? Yes, since your system has a Core 2 Duo it should support Lion.
Will you be happy with the peformance of this system running Lion? Probably not, unless you use it for only the lightest of tasks. 3 GB is really not enough if you have multiple browser windows/tabs open, run Microsoft Office, do any photo work, watch videos, or perform any of a variety of other memory-hungry tasks.
This system is also five years old. It is at the end of its service life. Lots of things could go wrong with it at this point, especially under the heavier load Lion will most likely put on it.
If I were you I would wait until I was ready to buy a new system.

I installed my new iMac with my Macbook Pro 2008 backup and created a network with the iMac and now the Macbook Pro cannot get internet.

I installed my new iMac with my Macbook Pro 2008 back up. I created a iMac network with Airport extreme, but now my Macbook Pro cannot get internet. any ideas on why or what to do about it.

Hello 1BillyMac,
It seems you have a network conflict that isn't allowing your MacBook Pro to connect to the internet. This may be caused by both computers sharing identical network settings. You may want to consider creating a new network location on your MacBook Pro to assign new network settings. The following article will instruct you on how to do that:
OS X Yosemite: Add a network location
A network location is a group of network settings
A network location is a group of network settings for your various network services (Ethernet or Wi-Fi for example).
If you often change network settings, you may find switching between locations quicker and easier than repeatedly modifying individual groups of settings.
For example, you might want to make a location for “home,” where you connect to the Internet with a telephone modem, and a location for “office,” where you connect to your company network and the Internet using Ethernet or AirPort.
Choose Apple menu > System Preferences, then click Network.
Click the Location pop-up menu, choose Edit Locations, then click Add .
Enter a name for the location, then click Done.
Enter settings for each network connection service you want to use in that location.
After you create your locations, you can switch all of your network settings by clicking the Location pop-up menu and choosing a different location.
Thank you for contributing to Apple Support Communities.
Cheers,

Can I access folders on my iMac with my iPad?

Can I access folders on my iMac with my iPad via the Cloud?

Yes .... If you use something like DropBox and you copy the folders that you want to access into a folder in your DropBox on the Mac.
What do you want to access? You still need an app or apps on the iPad that are compatible with the files that you want to access and download to the iPad....assuming that is your intent.

HT201364 I'm currently running OS-10.6.8 on my IMAC with an Intel Core 2 duo and would like to update to at lease 10.7

I'm currently running OS-10.6.8 on my IMAC with an Intel Core 2 duo and would like to update to at lease 10.7. Can this be done and if so how?

Only if you cannot upgrade to Mavericks.
Upgrading from Snow Leopard to Lion or Mavericks
To upgrade to Mavericks you must have Snow Leopard 10.6.8, Lion, or Mountain Lion installed. Purchase and download Mavericks (Free) from the App Store. Sign in using your Apple ID. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mavericks- System Requirements
       Macs that can be upgraded to OS X Mavericks
         1. iMac (Mid 2007 or newer) — Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) —
             Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) — Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) — Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) — Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) — Model Identifier 3,1 or later
         7. Xserve (Early 2009) — Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
Are my applications compatible?
         See App Compatibility Table — RoaringApps.
Upgrading to Lion
If your computer does not meet the requirements to install Mavericks, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space

How much sdram can the iMac 2007 20" dual core 2.4gHz take?

How much sdram can the iMac 2007 20" dual core 2.4gHz take?

Not SDRAM but SO-DIMM.
The max RAM is offically, 4 GB (two 2GB PC2-5300 667MHz DDR2 SO-DIMM) module but, with larger modules released after that model's specs were written, you can achieve 6GB with one 2GB plus one 4GB module.
You must get the 4GB from a Mac Savvy vendor or it won't work. OWC has the larger modules that are well-tested in Macs:

You did not look at Mountain Lion's Tech Spec's, click www.apple.com/osx and click the Tech Specs tab. That information has been posted for months.

Many third party Apple resellers have the ability to add a drive and maintain your warranty if you have one.
This is just a user to user forum. You'll have to contact your local reseller and retail store to find out if they will help you do that.
