24" iMac mid 2007 does not read full 4GB Memory

I brought a used 24" iMac mid 2007 with 2GB (one stick of 2GB in one slot) so I brought another 2GB stick same specs as the other one and my mac show only 3GB? Does anyone know the problem? Im running Mountain Lion and all updates has been made to the system.

Apple only offically supports 4GB of RAM however on my late 2007 iMac I have had 6GB running for about 3 years and it has never given problems. I'd recommend buying the 6GB kit from www.macsale.com. The exact address is:

My computer (MacBook mid-2007) does not recognise the battery suddenly. A cross appears on the image. I have tried uninstalling and re-installing it but it didn't help. Is the battery dead?

IMac mid 2007 won't read internal dvd drive

I have a mid 2007 imac and it no longer recognizes the internal dvd drive when I insert a blank dvd to burn.

Not a thing we can do, it has suffered a hardware failure so your only option is to take it into your local Apple Store or AASP to be serviced.
Good luck.

My iMac (mid-2011) does not start and AHT is OK

I had a similar issue last June and after I carried my iMac to Genius bar, they decided to replace the HDD on warranty. It solved partially the issue but after uninstalling flah player, everything was fine. So, 3 days ago, when this problem occured again, I uninstalled and reinstalled flash player.
But this time, it solved the problem only for one day (it should mean that is is not related to 'Flash"), and I have not been able to start it ever since.
I tried all kinds of resets and ran a bunch of tests with no result.
When I do the AHT (Apple Hardware Test) from disc2 , result is perfect and AHT does not find any hardware problem.
I tried to boot from disc1 (installation disc) but no way to boot. It could be that I have updated OSX 10.6 to Lion 10.7 and disc is 10.6???
It seems I am stucked. Any idea will be welcome

Have you tried a safe boot, by holding the shift key down as you boot? That will take longer than a regular boot, as it's doing some disk maintenance. If that works, try a normal boot.

HT1379 my video out on my 24" iMac mid 2007 will not work?

I recently attempted to connect my external video with no success. Is there a reason my ext video connection will not work with Mtn Lion? What can I do to get it to work? Thanks

Repeat of my above post first.
My 24" 2008 iMac has an audio in and an audio out port. If you have the same setup, have you tried using the audio in port? Mine has a speaker symbol for audio in.

IMac (Mid 2011) Does not wake up after long sleep

Hi People,
Having issues with my Mid2011 iMac (21,5", 2.7GHz). Just upgraded to 12GB RAM (2x2GB original + 2x4GB). System runs fine, no issues.
But when system goes to sleep for a longer period (a few hours) it will not wake up again. Neither by Keyboard/Mouse interaction (Bluetooth as well as USB) nor by pushing the powerbutton. I also performed the PRAM and SMC reset as described in the apple support resources.
Feeling a bit lost. Any Ideas?
Thanks in advance for any help!

Addition:
Performed a test of the RAM with memtest. No erros found. Also forget to mention that the Mac has also Software updates and firmware updates installed.

I have installed FCPX on my iMac (mid 2007) with a video ATI Radeon HD 2600 Pro 256 MB. Tis does not meet the minimum requirements. It seems to be ok but what kind of problems can I expect ?

Hey Luis. I not only remember…I still have mine (OS 9)! Works perfectly well…for some things; just need to be selective about what I ask it to do. (Also have its big brother Pismo running Tiger, which is still an extremely competent machine.) When I take them out of their cases, I'm still amazed at the G3's build quality.

HT201257 I have an iMac (Mid 2007) upgraded to Lion OS. My fan runs all the time at high speed. I tried the SMT reset without results. I could not try the AHT test because it is not on my computer or install disk. Any suggestions what I can do to correct

I have an iMac (Mid 2007) upgraded to Lion OS. My fan runs at high speed all the time. I reset the SMT without results. I had no way to do the hardware test.
Can I fix this high fan speed?

Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
If the above doesn't help then create a new user account. Log into the new account. Does this fix the problem?

Why won't my IMac Mid 2007 not work with ANY Microphone?

So I have recently received an IMac (Mid 2007) model that is used from my uncle. It is in GREAT condition with one flaw which I found out during a skype call. The mic didnt work. So I opened preferences, went to sound, went to input and saw that it was in "Internal Microphone". I changed it to Line In and used a separate microphone, still didnt work. Used another microphone to make sure it wasnt broken, didnt work. I have been looking online and didnt find anyone with my problem. It is so weird and I can't figure it out. On the other line the only time my friend (in the skype call) could hear anything was when I plugged in the external microphone and he thought it might work. I tried the sound with photo booth, skype, and just plain old volume. PLEASE HELP! I need to skype during my work on the computer!!! Thank you very much!
Also If you are willing to help out with other questions please do.
I have seen people run Windows 8 on a Mac product and would be willing to do that if there are no side effects to the cpu. Please tell me if there are any issues doing that, and if not tell me how.
This computer has 2GB of ram right now and is expandable to 6GB of ram. Is it possible to expand it over 6? And is it very difficult?
Should I upgrade to Mavericks. It is free and easy to download but I have been told that due to my low ram I should wait until I pump it up to 4 or 6GB of ram and then upgrade.
THANK YOU SO MUCH!!!

Isnt line in just a fancy word for a plug that looks like headphones?
No. The term "line in" refers to the signal level the input can accept. It has nothing to do with the type of socket/plug.
I just checked what Line in is and i do have a line in spot in my mac. So why would i need to buy the IMic?
Because you need a microphone-level input, which can accept the lower level of signal that a microphone puts out, and again, no Mac has had a microphone-level input in years. Line level is a much stronger signal.
So you need:
- a microphone that puts out a line-level signal. There are a few, but not many.
or
- a USB microphone
or
- an audio device that can accept a microphone-level signal. The Griffin iMic is one, but there are others.
Regards.

HT1338 Software Update is not finding latest release (April 3) of Java 2012 001 Update for Mac OS X Lion 10.7.3 on iMac mid-2007 that downloaded automatically on iMac mid-2011

Software Update is not finding latest release (April 3) of Java 2012 001 Update on my iMac mid-2007, but it downloaded it automatically on my iMac mid-2011 yesterday. Both are running Mac OS X Lion 10.7.3. When I try to download the update manually from Apple on my older iMac, it downloads okay, but when I try to open the dmg file, I get a warning message saying that opening this update may make your computer LESS secure. Do you want to proceed? (I did not).
Why would Software Update find this update and install it automatically on one iMac and not the other, if they are both running the same version of Mac OS X Lion? I checked the installed software list on my old iMac and the Java update does not appear there. Why would this update make my old iMac less secure?

Recall that Java is not installed as part of Lion.
You have to install it (and are asked if you want to) when you first try to run some java stuff.
Is it possible that the iMac 2007 does not have Java yet?
Try this: open Terminal (from Utilities) and type java -version (exactly like that, with the space before the hyphen).
What do you get?
Consistent with this theory is that the dmg thing gave you the warning - installing java might make your machine less secure because java is a means for bad guys to try to do bad things to your computer.

IMac (Mid-2007) USB Ports Not Working

So all of a sudden my iMac (Mid-2007) USB ports stopped working.
I turn on the iMac and it boots up. I can see desktop. I see the cursor in the upper left hand corner. I tried to use my Apple keyboard and mouse and nothing moves. I tried several different keyboards and mice and still the problem persists. I shut down and reboot it restarts and the same problem.
I've read several posts on the Internet stating it could be a power supply issue. If it was PSU why does it even start up. If its logic board thats an expensive repair as I've already looked around for logic board replacements. I wouldn't even know what Apple would charge to fix this issue.
Can somebody help with this issue?

Reset the SMC > Resetting the System Management Controller (SMC) only wait for a few minutes in step three instead of 15 seconds.
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Wait fifteen seconds. <---- Wait a few minutes.
4. Attach the computer's power cord.
5. Wait five seconds, then press the power button to turn on the computer.
Then if that doesn't reset the USB port overload protection, go to > Apple - Find Locations and contact your local AASP to get an estimate.

MacBook Pro (Retina, 15-inch, Mid 2014) will not read an SD card in the SDXC card reader. Does anyone know whats going on?

MacBook Pro (Retina, 15-inch, Mid 2014) will not read an SD card in the SDXC card reader. Does anyone know whats going on?

Hi David. I don't have as modern a Macbook Pro as you, mine is a 2012 model, but perhaps I can help. I often find that my SD card will not load when I first insert it. I have to remove it and then put it into the slot again firmly.
You also haven't posted any information about the SD card. What size is it, do you know how it is formatted, has it worked in that same mac previously, where did it come from, does it currently work in another device (such as your camera)? This sort of information will help to narrow down the problem.
If you post some more information I'm sure people will try to help you. In the meantime, if you look at your post again you should see "More Like This" at the bottom of the page and you may find an answer in some of those related posts.
Hope that helps.

Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the
     computer and after the chime press and hold down the OPTION key until the boot manager
     screen appears. Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.
5. Reinstall Yosemite from Scratch:
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
How to Clean Install OS X Yosemite
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.
