I have a 2008 20 inch imac

i have a 2008 20 inch imac with snow leopard , and would like to upgrade to lion with only 2gb ram ? and where can i upgrade my ram ?

You can buy ram at any computer store around. You can do it by yourself, it is really simple, just look around on google there is plenty of tutorial to learn how. Ifixit.com is a good place to buy ram and learn how to change it.
But be sure to have the minimum requirement for lion
Good luck
General requirements
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

I was having problems burning DVDs' fro iDVD and it turned out my burner is at fault I have a 27 inch iMac using a OPTIARC DVD RW AD-5680H. Where can I buy a replacement in UK?

I was having problems burning DVDs' from iDVD and it turned out my burner is at fault.
I have a 27 inch iMac using a OPTIARC DVD RW AD-5680H. Where can I buy a replacement in UK? I have seen these with SATA is this the correct cable for my mac?
I have also tried the Mac superdrive but my imac wont recognise it as it's been configured for macbook air and mini mac. I know I can "make" it work by doing something or other in com.apple/plist, but dont want to mess about in there.
I'm also told an external drive would work but does "mac compatible" mean only for air and mini as their own superdrive is or all macs?
Any help appreciated before I convince myself mac is no better than windows pc!

Thanks but this didn't really help.
I can buy the drives at a dozen places but none of them seem to know what connection is correct (SATA etc) and that includes the apple store. It was the store who told me buy the superdrive and all my problems would be over. Wrong! It isn't recognised by imac as it's confifured for air and mini mac. Only way to make it work is as i said in earlier post. (Would you be happy buying a car you were told would start and then discover you have to open the bottome and fiddle to make it go?)
The apple store I would not even consider taking it to. Days without the pc, over priced and don't have a good reputation for actually fixing things!
But thanks

I have a 27 inch iMac with maverick os. my current version of iMovie (10.0.6) will not open older projects i created in iMovie 9.0.9. I can find the projects and they have a ".rcproject" file extension

Thank you GeeD. I'm still stymied.
I have moved the Event and Project Folders to the "top-layer of the drive" as the instructions state, right alongside the System Folder, Users Folder and Applications Folders.
When I open iMovie 10.0.8, the Events and Projects Folders are empty:
When I select File/Update Projects and Events, I get an alert box that says iMovie couldn't find any:
Not knowing exactly what is meant by the "top layer" in the instructions, I moved the Events and Project folders back inside the "Movies" folder where I found them (but then not where I would call the "top" layer, but rather "iMac/Users/Home/Movies/iMovieProjects". Then I tried to "Update Projects and Events" and received the same alert: "iMovie could not find any projects or events to update."
Then I tried to update iMovie 9.0 (iMovie '11 version 9.0 (1073)) to version 9.0.9 .
[As an aside, the nomenclature of iMovie drives me nuts. The latest version is 10.0.8, which us newer than iMovie '11.]
Back to the update of version 9.0 to 9.0.9.
Presumably because I have version 10.0.8 installed, I got this alert box:
So, I cannot update version 9.0
and I cannot "Update" the Events and Projects created in version 9.0.

Hi,
This is the compatibility list
http://www.apple.com/osx/specs/
if your iMac is mid2007 or newer - yes.
You will need to upgrade to 10.6 (Snow Leopard) first buy DVD from online apple store
Then to 10.7 Lion - buy and download via Store App included in SL
and then 10.8 Mountain Lion upgrade the same steps as Lion

I have an 20 inch Imac 2,4 GHz Intel Core 2 Duo and I want to introduce Final Cut Pro X into the machine, can I change the Vieodcard ATI Radeon HD 2600 Pro 256 MB, into a more suitable videocard? Or is that not possible?

The GPU in a iMac is NOT upgradeable.
You should check to see if your model of iMac meets the minimum specs to run FCPX.
I believe that your GPU is NOT OpenCL capable, and hence not supported.
Even if it works, you would probably get marginal performance.
What you can do is download the trial version and see how (and if) it works.

I have a 2008 vintage iMac with 2.8GHz processor and recently upgraded to OS X 10.9.5. Soon after theupgrade the mail system started switching the senders address to another address, but same user name. How do you fix this?

Thanks for the reply,. I went to the site provided and executed the directions but this did not solve the issue.
Even more details:
If I send a message to the Jane Doe address from another account on this machine (all my family uses the same email services provider and each have accounts set up on this machine), when you open it, it shows Jane Doe then the <applejax.xx> address AND the picture associated with the Apple Jax account.
So the problem shows up when the message is sent to this account from this machine, AND when it is sent from this machine from this account. No other accounts on the machine are effected.
I have sent and received email messages from the mail service provider's website, and everything is fine.

Have 2006 24 inch imac running 10.75 Lion os having repeat kernel panic attacks 2006 imac

I have a 2006 imac (24 Inch) using Lin 10.75 OS. It keeps having kernel panic attacks and needs to shut down. It is also very unstable and freezes maore and more often. Any suggestions?

Nada. And yes it displays the correct resolution of 1920 x 1200. And yeah pretty much what I'd call cosmetic too but it just bothers me after a while. Yep I'm one of those people lol my computer runs perfectly fine but I still find something wrong but it's just wrong. System Profiler is not supposed to be incorrect. But just seeing if I'm the only one with this problem or if just the 7600 GT iMacs have this error.

24 inch iMac screen resolution options

I have a 24 inch iMac. The native 1920x1200 resolution is great for displaying large amounts of data, but is sometimes too small for my aging eyeballs to see comfortably. The next option is 1344x840 which is easier to see, though a bit grainy, but I lose huge amounts of displayed data on web pages and things like that. I'd love the option for 1680x1050 (like the native res on 20 inch iMacs) but it is not an option on my display preferences selection menu. Why is that resolution not an option on the menu? Can I get to that resolution another way?

To SteveCG
I must be a conspiracy theorist. I've just bought a 20" iMac after many friends gave Macs such a great rap about their graphics etc. The 6 year-old 13" Dell Inspiron 4000 Laptop I'd just left produced much sharper screen images. Most of the work I do is just producing and reading text - reports and emails etc. I'm am SO annoyed that fonts are not sharp and clear on the 20" screen. Increasing the size (Command +) does not make any difference - the edges are still fussy.
I complained (fruitlessly) to Apple Support after I found the best resolution I could get was only 1680 x 1050. Was told that there was nothing Apple support could do to improve it and buying a better graphics card would not help since the maximum screen resolution was related to the composition of the screen structure.
And my theory? Apple will shortly launch a better higher resolution screen on the market and encourage us all to rush out and buy one.

I have a 24 inch 2008 iMac. When I press the power on, unless I hold it for 6 seconds, it abruptly aborts the power on in a few seconds more.

I have a 24 inch early 2008 iMac. To power it on, I have to unplug it, wait 30 seconds, plug it back in, hit the power button, and hold the button for exactly 6 seconds after it starts to whir before releasing it. When I press the power on, unless I hold it for exactly 6 seconds, it abruptly aborts the powering up cycle in a few seconds more. Also, if its been off for a while, even if I unplug it, and plug it back it, it sometimes spontaneously starts the power up cycle, but aborts it in a few seconds. I've had to do this for the last two years. In that interval, has been completely reformatted and restored once . For perhaps one or two weeks, it powered up properly, than reverted to the state described above. The Genius Bar hasn't been able to help. What's up with this?

This could be a software/state problem or a hardware problem. Here are steps to resolve the former.

My bad?
You're original response was questions/post about an iMac. Now you've edited it to ask about a Mac Pro?
You can more easily add internal drives in a Mac Pro.
Not too terribly easy to add/replace drives in an iMac.
If younhave questions about a Mac Pro, try posting in the Mac Pro forums.
Much more knowledgeable users there.

I have a mid year 2007 24 inch iMac and will be purchasing a new 27 inch Retina iMac, what is the easiest way to transfer the data and files from my old machine to the new one?

I have a mid year 2007 24 inch iMac and will be purchasing a new 27 inch Retina iMac, what is the easiest way to transfer the data and files from my old machine to the new one?

Following up on this thread,
I have a new iMac on the way and my current is from 2008, never had a problem but I am sure there are internal issues that I would prefer not to transfer.
I have no issues other then the slowness in certain programs and that is the main reason to buy a new one.
Programs like numbers and pages seem to take a longer time to open after I update to Yosemite.
I only use 272GB of 500 GB, my memory is 4GB and I am upgrading to 8Gb and bought the 4.0 processor.
Question:
Is there a way to manually transfer items or would that be a waste of time in that if there are issues they could be anywhere and would transfer anyway?

I have a 2008 iMac 21.5" 10.6.8 Snow Leopard with 4.1.3 VMWare and windows 7.Mountain Lion initially refused to down load as I had back up on the HD. this was removed and installation was accepted but froze in the initial stages with 33 mins to go.

I have a 2008 iMac 21.5" using 10.6.8 Snow Leopard with VM Ware 4.1.3 supporting Windows 7. Initially ML OSX refused to install due to Back up on HD which I removed to trash.It then proceeded but froze up in the initial stages with 33 mins remaining. I was lucky enough to quit and restart using 10.6.8. With all the problems on this chat line, it appears it may be best to leave Mountain Lion well alone, and cut losses rather than tempt fate.Has anybody anything positive to say or help with?

I have had wireless issues sense Leapord, any fixes yet? its a shame that my wife has to sit in front of our 27 inch imac on a $300 Windows computer to use the web effectively. I have tried all fixes and some work while others don't but all temporary

This Lion wireless issue has become more than just an irritation, so much so, my wife has resorted to sitting in front of a 27 inch imac with a 300 dollar Walmart Windows computer to get the bills paid and use the web. And yes, there is not a fix out there I haven't tried over the last year or so, some worked and some didn't, but all were temporary at best. Same issue with my Macair, I wonder if its a hardware issue, like the video card in my 2006 MBP, it went out after the warrenty and then I found out there was a calss action suit going on over it, unfortunately Apple wouldn't cover it and wanted 7oo bucks to fix it, sold that as parts.
While i really like me Macs, I own three, I may have to bow out and stick with LINUX, that has yet to let me down, anyone know if Mountain will fix this issue? or are we all just waiting for defective WiFi cards to fail at our own expense, PS, got three Macs for sale.

Sounds like you're getting kernel panics, which are usually, but not always, caused by hardware problems, with memory being one of the regular culprits.
First thing I would do is to get our your original OS X disks, insert the first one (should say 'AHT version x.x' in small print on the label - if not, find the one that does), and reboot holding the Alt key down. Choose the Apple hardware test, and when prompted, choose the extended test. If you have either of the TechTool programs, they can do similar testing. Does that identify any hardware issues?
Next, I'd download rember from http://www.kelleycomputing.net/rember/ . This is a memory testing program that you can set to run overnight. Does it come up with any errors? If so, try resetting your memory card(s) by removing and putting back into the computer. Rerun memory test.

Hi there,
The simplest way is to drag it across wirelessly using the 'Airdrop' application once both computers are near one another. 'Airdrop' can be found near the top, on the left hand side menu, within 'Finder'.
