Startup problem mid 2007 iMac

Can't get past login screen I just get the Beachball, I can access guest login

If you still have them use disc 2 from the original install discs that were delivered with the Mac and Using Apple Hardware Test - Apple Support, run AHT in extended mode 2-3 times back to back. If it finds errors (as I believe it will) that means the machine has suffered a hardware failure. The reason to run AHT multiple times is it does not always find errors after the first or second pass, however when it does they are correct.
Due to the computer being 8 years old, you may want to consider replacing it. However if it's only a hard disc that has crashed then you can take that to an Apple Authorized Service Provider and have it replaced if you want.

Problems with Installing 4GB RAM on mid 2007 iMac

I ordered 2 X 2GB sticks of PC2-5300 DDR2 SODIMM RAM for my Boss's mid 2007 iMac from Crucial.com. Well they arrived a few days later and today I have been trying to install them for a few hours now without any luck. I have installed new RAM about 5-6 times without any problems before on different MacBooks and iMacs. After this install I plugged back into the wall and hit the power button, the iMac made a little noise (internal noise) then nothing, just a blank screen. I thought maybe the RAM was bad so I inserted 2 other chips (we ordered 4 X 2GB to upgrade 2 iMacs) and still no luck. After making sure the iMac would boot with the old RAM (which it did), I tried installing 1 X 1GB with 1 X 2GB and it booted up perfectly. I did this with all four 2 GB RAM chips to make sure they all worked and they did. Each time I successfully booted, I went to the system profiler to make sure it recognized 3GB of RAM and it did. So my question is why is this mid 2007 Aluminum iMac not working with 4GB of RAM, but it works perfectly with 3GB? Thanks in advance, sorry for the long question.

+It seems to me that it is not just a problem with the RAM but with the imacs themselves.+
How does this make any sense when one considers that Apple successfully specified, produced, sold and delivered all three iMac (mid 2007) models with an optional 4GB of RAM pre-installed?
In addition, Apple has, without issue, sold large quantities of that same RAM online and over-the-counter for customer upgrades. Much of all that 2GB, and the latest 4GB RAM, as usual, has been manufactured by Micron, the publicly owned U.S. manufacturing company parent of the Crucial direct sales division. The same type of RAM was also being provided to Apple by other manufacturers.
I received my two orders of upgrade RAM from Micron/Crucial even before I had purchased my 24-inch iMac, and it's worked great ever since I installed it. I also installed the second half of that order into my current MacBook, purchased a month after the iMac, and it's also been working great ever since. These are certainly superior Apple products.
Obviously there has been a change in RAM manufacturing design at Micron, probably due to their change-over to the costly, challenging high-tech 50nm and 40nm manufacturing technologies, and it is nothing more than Micron's problem.

Why is my mid 2007 iMac so slow now that I've loaded 10.9.4

Why is my mid 2007 iMac so slow now that I've loaded 10.9.4? Everything seems to be slow. It was quick enough on 10.4. I now have wireless connection issues, and wired keyboard connection issues?

Mid 2007 iMac SSD in optical bay - cannot write to last block of device

Hi All,
I've just replaced my optical drive in my 20" mid 2007 iMac (Dual core, 2.4 Ghz, 2 Gb RAM running Mavericks) with a solid state drive (Crucial MX100). The plan is to transfer my boot disk to this drive while keeping my 1 Tb HDD for media and such.
I followed the ifixit guide and it all went smoothly, however when I try to partition or erase the new SSD using Disk Utility, it tells me "Operation failed - cannot write to last block of the device". After googling, I found some answers here that suggested the optical bay cable may be faulty, so I bought a replacement and swapped it in, but no such luck, same problem. I also saw some threads suggesting that the boot disk should be in the original hard drive spot, but since this isn't the boot disk (yet) this shouldn't be the issue.
My computer recognizes the new SSD but won't allow me to partition it. Any suggestions on how to proceed?
Thanks!

3. The new disk is just bad.
OK. If that's the case, I'll just get another disk.
Lots of problems with that hybrid drives on Mac's on these forums, get another one that's 7,200 RPM and from Western Digital, not Seagate.
With a 7,200 RPM you get more performance across the entire drive, not just what's cached in the small flash portion of the hybrid.
https://discussions.apple.com/community/notebooks/macbook_pro?view=documents#/
1. Hybrid drives: I'm on number 8 in 6 different machines, no problems at all, what happens when you try?
2. The OP is not using a Hybrid.
3. Lot's of problems with WD drives not booting on these forums though.

I have a mid 2007 iMac.    2 GHz Intel Core 2 Duo, 4 GB 667MHz DDR2 SDRAM, OSX 10.9.5.   I attempted to do the latest update and got the message: Start up disk is full. Delete files. How do I do that?

Freeing Up Space on The Hard Drive
1. See Lion/Mountain Lion/Mavericks' Storage Display.
2. You can remove data from your Home folder except for the /Home/Library/ folder.
3. Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.
4. Get an external hard drive on which to store some of your files after which you can
      erase the data from your internal drive to free up space.
5. Also see Freeing space on your Mac OS X startup disk.
6. See Where did my Disk Space go?.
7. See The Storage Display.
You must Empty the Trash in order to recover the space they occupied on the hard drive.
You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.
Try using OmniDiskSweeper 1.8 or GrandPerspective to search your drive for large files and where they are located.

Can I use faster memory in Mid-2007 iMac?

I currently have factory spec (1 GB) memory in my 20" (Mid-2007) iMac. Specs for memory in this machine say I need pc2-5300, unbuffered, non-parity, 200-pin, 667MHz DDR2 SDRAM. I noticed my hardware has an 800 Mhz bus.
1) Can I use 800 Mhz RAM that is otherwise the same spec?
2) How important is CAS Latency (e.g., the installed memory is spec'd as CL=5, the 800 Mhz RAM all seems to be CL=6)?
Any help is greatly appreciated!

I totally agree with lenn5! Many folks here in the forum have reported all sorts of problems, everything from kernal panics to won't even boot when they installed the 800MHz ram. You will see a great improvement in performance by adding another 1GB or 2GB module in the empty slot, or max it out with a 2x2GB kit.

I upgrade my mid 2007 IMac to Yosemite and it has been running very slowly since then. I have 3GB of ram. Should I go back to Mavericks?

I upgraded my mid 2007 IMac to Yosemite and it has been running very slowly since then. I have 3GB of ram. Has this been a problem for anyone else?

Your iMac year and model is low on RAM.
3 GBs is really not enough RAM to operate your Mac under OS X Yosemite OR Mavericks smoothly and efficiently.
New Macs now ship with 8 GBs of RAM as minimum, base installed amount of RAM.
Your Mac model can take a maximum amount of 6 GBs of RAM.
I strongly recommend purchasing and installing the necessary RAM amount to meet the 6 GB RAM total.
If you live in the U.S. , Correct, compatible and reliable Mac RAM can be purchased from online Mac RAM sources Crucial memory or OWC (macsales.com).
OWC (macsales.com) has the proper RAM module or kit needed to get your Mac to the 6 GB RAM total limit.
http://eshop.macsales.com/item/Other%20World%20Computing/5300DDR2S6GP/
RAM is user installable and is, relatively, easy to install be newbie and novice Mac users.

Good Luck!

Connecting mid-2007 iMac to LG TV via mini dvi to HDMI

I am trying to connect my mid-2007 iMac to my 42" LG HDTV to no avail. I am running iOS 10.6 Snow Leopard. I bought the mini dvi to HDMI adapter and plugged the iMac into the TV. I went to the display tab in the system settings and see that the iMac recognizes the tv. I went to the arrangements section and it recognizes the tv. When I click on gather windows it even calls it the LG TV. However, there is nothing showing on my TV. It says no input detected. When I move my mouse to the right side of the screen it disappears like it is going to a second monitor.
Any thoughts?

Hey Corinthone, did you ever figure it out? I have a mid2007 iMac running snow leopard & a 120hz LGTV 42". I was having the same issues as you(yes Frankie, I made sure I was selecting the correct hdmi input). Now with the same setup, my LG recognizes the HDMI input from my iMac. It says connecting but then 'no signal' on the screen. The hdmi2 is still showing a connection in 'inputs' just no picture on TV. I started changed the setting via my mac but still nada. The lg is 120hz. Does that have anything to do with it? Thanks

My mid 2007 iMac doesn't recognise 2GB RAM module in DIMM/1

I am trying to upgrade the RAM in my mid 2007 iMac from 1GB to 4GB. It originally had a 1GB module in slot DIMM/0 and nothing in slot DIMM/1. I inserted the two new 2GB modules, one in each slot but DIMM/1 just reports as being 'empty'. I have tried swapping the modules and different configurations of 1 & 2GB modules but DIMM/1 only reads the original 1GB module (from DIMM/0) and reports 'empty' when either of the two 2GB modules are installed.
I have reset PRAM, checked EFI firmware update and updated OSX to version 10.6.8 (from 10.5.8) but still the same result. The best I can get is 3GB (2GB in DIMM/0 and 1GB in DIMM/1). I am definitely pushing the modules firmly into place. Is there anything else I can try?

Your machine will accept up to 6GB of RAM however you must a) have the correct specifications, no variations at all and b) must push hard with both thumbs to fully seat the RAM. The correct RAM for your system would be the specifications shown here. I suspect 1 of three things with the RAM you bought.
1. Wrong specifications!
2. Incorrectly installed
3. Defective RAM
I would STRONGLY recommend using Crucial or my preferences OWC, which is the memory shown in the link.
BTW I have a late 2007 24" 2.8GHz iMac with 6GB of RAM.

I want to dual boot Windows 8 on my 20-inch, Mid 2007 iMac, from an external USB drive.

I want to dual boot Windows 8 on my 20-inch, Mid 2007 iMac, from an external USB drive. The internal drive is completely dead, it doesn't even show up in Disk Utility. I'm running 10.8.2 from the external drive. When I start Boot Camp Assistant, at the Introduction page, when I press the continue button nothing happens. Do I have to have internal drive to run Boot Camp Assistant? Can anyone provide me with the steps to dual boot, with his setup? Thanks in advance!

Hi maczimillon,
Only follow these steps, it works for my:
Open "System Information" and note your "Boot ROM Version" (some like MBP51.007E.B06)
Navigate to "Utilities" in Finder and open the package contents of -BootCampAssistant.app- with right click. Duplicate the "Info.plist" file to the Desktop e.g. and open that with Text Editor.
You must locate the keys "DARequiredROMVersions"and "USBBootSupportedModels"
Add new strings with the information of your machine under booth keys (step 1), always respect the format, such as: <string>MBP51.007E.B06</string> for the frist key and <string>MBP51</string> for the second key.
Save changes and replace the original plist file (it may ask you to enter admin pass)
If you proceeded correctly you will see the checkbox "Create a Windows 7 USB install disk" enabled in Boot Camp Assistant.
Then you can follow the usual Boot Camp installation using your WIN8 DVD iso image . The assistant program will proceed resizing your disk partition and installing necessary drivers for your iMac.
I strongly recomends you to use thirld party's bootloaders like rEFInd (rEFIt) because of the Apple SMC versions of some old machines should not be able to boot properly from external devices like USB drives.

Windows 8.1 on Mid 2007 iMac

So, I need to run Windows 8.1 on my 24-inch mid 2007 iMac, running OS X 10.9.4. Yup, I could run it in VMware Fusion, but this time I would prefer to run in directly on the hardware.
I went out and paid $139.99+tax for a copy of Windows 8.1 pro 64-bit.
When I tried to install it on my mid 2007 iMac, using Boot Camp it tells me that ONL

I have a 24-inch Mid 2007 iMac. Should I upgrade to Yosemite? I was advised by genius bar that it would slow down my iMac.

According to sources such as http://mactracker.ca download database specs for
the iMac (24-inch Mid 2007) your computer can use more RAM than it has now.
Maximum Memory: 6.0 GB (Actual) 4.0 GB (Apple)

And so it should work better even if you stay with Mountain Lion OS X 10.8.5.
The hardware upgrade will help the Mac OS + applications, in basic functions.
[This computer is already considered 'vintage' by Apple...]
Depending on the amount of use the computer has seen so far, it may also be
a candidate for a replacement hard disk drive; perhaps a larger capacity, too.
If you consider an upgrade, also consider a complete backup and a bootable
clone of the current (if updated to 10.8.5 with its applications updated) OS X
on an externally enclosed hard disk drive with its own power supply. You can
see a few of these that do not run on Mac port power, & standalone, at OWC.
{The company known as OWC is macsales.com, a fair example of mac-centric
supplier of quality products for Mac community, awhile. Or so people tell me.}
Clone utilities such as superduper, carboncopy cloner, or disk utility can work.
Test a cloned OS X copy for boot-ability and other function before moving on.
Could be you'd be better off with this computer on Mt Lion than a later OS X.
And a newer later computer should also have hardware specs and some up-
ward expandability for use with the expected new & future changes to OS X.
Hopefully you can get some fair use and more years from your iMac 24".
And that means hope for the best, and plan for the worst. Backup, backup...
Good luck & happy computing!

Mid-2007 iMac Running Mavericks Windows 7 Home Premium 64-bit Install

How do I go about installing a Windows 7 Home Premium 64-Bit (OEM) partition on a mid-2007 iMac running Mavericks?
Apple says that 64-bit Windows 7 isn't supported by my model iMac, but I know for a fact that other people have gotten it to work. I'm just a little unclear on how exactly to do it. In any case, I made the mistake of buying two copies of Windows 7 64-bit under the assumption that they would install just fine on my iMac and MacBook Pro (MacBook Pro is from 2007 as well), so I need to get this working.
What version of Boot Camp should I use? What version support drivers should I download? Apple says that Boot Camp 5.1, which is what I have, is incompatible with my iMac, and it says the same thing for every driver download that supports 64-bit versions of Windows 7, but would it be correct to say that this "incompatibility" is only the case if I don't first modify my Windows 7 installation disc according to the instructions in the attached link?
There is a Windows XP partition on my MacBook Pro, so I figure I can get on it to modify the installation disc before attempting a 64-bit Windows 7 install on the iMac.
