Imac 2.4 GHZ Core 2 Duo - Sudden Wireless problems (after 1 year + of use)

This is weird.
I have three macs on my wireless network. All work find and blazing fast until yesterday.
Now, my Imac 2.4 Core Dual internet speed is so slow or does not work at all.
The other two Macs (Macbooks) work fine.
Any suggestions of cause?
Additional info:
Nothing was changed on the Imac. Nothing was downloaded. One minute everything was fine and then next...nothing.
I have tried restarting.
I have tried reseting the airport.
I have even let my Imac shut off for 24 hours.
After restarting, load time gets better for one or two pages and then poof! Back to slow/non existent loading...
Any ideas helpful.

Try this - Open network preferences, make sure WiFi is selected, click the Advanced button, click TCP/IP, click Renew Lease.
While you are in the same screen, check your DNS settings and compare them to your machines that are running fine.

My Mac experience so far...17" iMac 1.83 GHz Core Duo

I bought this iMac the first of December as CompUSA was closing out the last of their older iMacs. It was a great deal at $900 with Apple Care included for 3 years. I upgraded the RAM and am running a second monitor. I also added a 250 GB Iomega USB drive.
All in all its been great so far with a few exceptions.
1. My mouse gets stuck in right click mode. I have to unplug it and then its back to normal again.
2. The keyboard space bar sticks about 1 out of every 10 strokes. This is annoying especially with a brand new keyboard.
3. My CD's and DVD's won't eject. The drive tried to kick them out but due to some sort of resistance it never kicks the disk out. If I press the two layers of the display together...front and back it takes the pressure off and the disks pop out just fine. This seems more like a case that isn't sealed up tight.
4. I have or had a dead pixel. It was green but when I rebooted it seems gone. Fingers crossed on this one.
I've been holding off on taking it in for repair. I hate the idea that I have to loose it for a week when its mstly brand new.
If anyone has any similar problems or can suggest any fixes for any of the above I'd appreciate it.

Brett - A sticky mouse and keyboard as well as an optical drive that doesn't eject all adds up to more than an open box unit to me. I strongly suspect that you got a demo unit. Doesn't really matter, you did get a pretty good price, especially with a 3 year warranty.
You need to take the computer to a service center or call AppleCare. The keyboard and mouse can be handled via mail easily but I'd strongly suggest taking the computer itself to a service center to be looked at.

Have MacBook Pro (ancient) has 2.16 Ghz Intel Core Duo with 1 GB 667 MHz RAM using OS 10.4.11. Can I upgrade OS? If so, how far? And can I add more memory? I realize this is an old laptop but I need to wait to upgrade to new.

G4 iMac migrates to Intel Core Duo

I just migrated the contents of my 17” G4 iMac to a 20” Core Duo. The only piece of software that wouldn’t run on the new Mac was Nikon Capture 4.4.1; upon launching, it told me that it was missing necessary files. I reloaded the software from my original 4.0 discs. This time the error message said to click to go to PACE and run the installer, which I did. The installer claimed to run successfully, but NC4 still claimed to be missing files. At this point I went to the NikonUSA website and downloaded the NC4.2 updater. After running this and rebooting, NC4 ran just fine. I finally updated it back to V4.4.1, which also works properly.
Rosetta notwithstanding, compared to running NC4 on the G4, it’s much faster. Opening a D200 RAW file on the Core Duo is about as fast as opening a D2h file on the G4--not instantaneous, but reasonable at around 7 seconds. Same goes for edit files.
With 2 gigs of RAM on the Core Duo, NC doesn’t suck up all the memory, as it did on the 1 gig G4. No “page outs” when working on several RAW files at a time. This is much better performance than I had been expecting from it.
PSE3 work reasonably well, too. Faster than on the G4, at least.
While I was trying to get NC4 to work again, I did play around with iPhoto6. It seems very fast and has some interesting features, so I’ll probably start using it too.
All the included iLife6 programs seem to work well, and much faster than on the G4.
I had no problems with any peripherals except a very old USB CameraMate Compact Flash card reader, for which the OS X driver appears to no longer function. A no-name card reader I got for free from OMax works fine, though. So does my Epson 1650 flatbed ( I use PSE3 to access it), a QPS external firewire drive and an Epson 1270 printer. No problems with Wi-Fi or ethernet,either. When I plugged the ethernet cable fron the Core Duo into my Airport Extreme base, the computer automatically switched its settings from Airport to ethernet--neat!
This is the seventh Mac I’ve owned and the easiest migration so far. The improvements in performance and in the quality of the display greatly exceed my expectations.

HT4914 I want to transfer my entire iTunes "folder" from a newer iMac 3.06 GHz Core 2 machine running iTunes 10.7 to an older iMac running OSx 10.5.8. How best to do this and keep all my data, tags and covers in tact?

I want to transfer my entire iTunes "folder" from a newer iMac 3.06 GHz Core 2 machine running iTunes 10.7 to an older iMac running OSx 10.5.8. How best to do this and keep all my data, tags and covers in tact?

Firstly, time to get rid of the 2 x 512MB FBDIMMs in there, they add more heat and use more watts then they add to the system. If you need more, and 4 or 8 DIMMs is ideal, Amazon has 2x2GB sets $22 - about 1/50th what I paid for 1GB new.
Buy a 250GB Samsung EVO SSD $129
Pick up Carbon Copy Cloner http://www.bombich.com to clone the system to the SSD
A sled adapter for the SSD from Icy Dock $14 Amazon.com
7-8 years overdue for new system drive! amazed it lasted this long. An SSD plus some WD Black 2TB drives or larger should do the trick.
you can also put the SSD in the lower optical drive bay and use one of the two ODD "spare" SATA ports for the SSD - an SSD is the best way to improve the performance of our old Mac Pro 2006-7 models.
When you downloaded the Lion installer that was when to create a flash type installer with Lion DiskMaker.
If you have put in a new-ish graphic card then OS X 10.6.0 may not support it.

1.83 Ghz Core 2 Duo or 2.0 Ghz Core Duo???

Just curious if anyone would know which would be faster, a 1.83 Ghz Core 2 Duo or a 2.0 Ghz Core Duo. I saw both listed on the refurbished Apple site. The original 2.0 Core Duo has a Superdrive (not that I really have a need for one but you never know). Both have the same size harddrive and RAM. The difference in price is $50 more for the 1.83 Core 2 Duo. I am leaning towards the 1.83 Core 2 Duo with Combo Drive only because it is newer, even though the drive is slower. Does anyone have any thoughts or advice or a direct comparison between the two?
Thanks,
Thom

If it matters, the core 2 duo is a 64-bit processor, while the core duo is 32-bit. C2D also has 802.11n support (draft-n at this time, but it's upgradeable).
While the processor is 64-bit, the system is still limited to max 3 gb of RAM, so there are no huge advantages other than the fact that it's a tad bit faster; very few applications are optimized for the newer 64-bit processors anyway. I'd say it's a wash. Get the C2D if you want the "latest and greatest" 2nd generation model, there are always subtle differences between generations. If it doesn't really matter, just get the core duo.
As for the drive, there are 7200RPM sata laptop drives available on the market now; a 80 gig Hitachi will set you back about $100. It's a painless upgrade process.

7 angles (cameras) edit - is it possible for iMac 3,06 Intel Core Duo?

or i want too much?
Hi there! I have 7 tracks of ProRes HQ 1920 X 1080 50i to perform a multitrack edit. Problem is - doesn't show a realtime preview, so i can't choose a proper track
Is it possible with my iMac 3,06 Intel Core Duo, 2 Gigs of RAM, + strip 1TB raid? I guess i'm in lack of memory If i increase the amount of RAM to, lets say, 8 Gigs - would it solve a problem?
If not - is there a way of some low resolution editing? Thanks

ProRes HQ, certainly not. Definitely not over Firewire and almost certainly not over even the internal drive (not that you'd want media on your system drive anyways). Yes for low-res editing, it's called offline editing. Someone else will probably have a lint for you to Kenstone or Creative Cow to easily tell you what to do, but when I did it for me, I went from DVCPro HD to DV NTSC. As long as you export the correct timecode, you should be set to then edit in that offline format's sequence then Media Manage back to the full-quality files.
Hope this helps,

My iMac has an Intel Core Duo processor, what can be done to upgrade to Lion?

my IMac has an Intel Core Duo processor. What can be done it to allow me to upgrade to Lion?

Got 2GB of RAM and 7GB of disk space as well?
Got current BACKUPs in case something goes horribly wrong?
If so, upgrade/update to 10.6.6 or later and The App Store icon appears. For US$29.99, you can download Lion.
If you fear you will need a DVD of it, you must make one after downloading and BEFORE you install, as the image is consumed during the Install, and not available afterward.

which is the normal temperature of operation of the a Macbook pro 13" 2.4 GHZ core duo i5 500GB hard disk? due to my laptop is very hot, arrives to 89º celcius, when I am playing a game and normal when I am internet, is of 63º to 73

That's too hot, for just Internet.
I can see if you just stopped playing a 3D game and then went to use the Internet you would get that sort of temps.
Try booting a cold machine, then only surfing the web, if you get 63-73 C temps, something is wrong, it should be 40-45 C.
The integrated graphics machines are hot, but yours seems too hot.
Perform a hardware check, if it says something, write it down and make a appointment

Which install DVDs on ebay for imac 20" tiger intel core duo?

Hi everbody.
Those folks selling install DVD's on ebay don't usually specify which machine their discs are for.PLUS THEY DONT ACCEPT RETURNS.
Anyone know how I can determine which Tiger discs will restore my imac 20" intel core duo SERIAL NUMBER W86****NU2P ???
Any help will be great, thanks!!
Jorge in SA

Please don't post your serial number in your post. Take a look at this link http://support.apple.com/kb/HT1159#iMac it will have the version of Mac OS that came with your iMac. Try to match that with the DVDs on eBay. Or you can always call Apple to order it.
