My iMac (24-inch, Early 2009) will not play DVDs.

My iMac (24-inch, Early 2009, purchased new from an Apple store) will not play DVDs. When I attempted to open the DVD Player file in Utilities I got the following error message: ‘A valid DVD drive could not be found. [-70012]’ I've downloaded nearly every software update that Apple has notified me has come available. It's been several years since I last used the CD/DVD player, but i was quite surprised and unhappy today when it spat out every DVD I inserted. Anyone know how I can resolve this problem?

Hi there,
Your machine should be supported, the requirements for Mountain Lion are:
iMac (Mid 2007 or newer)
MacBook (Late 2008 Aluminum, or Early 2009 or newer)
MacBook Pro (Mid/Late 2007 or newer)
Xserve (Early 2009)
MacBook Air (Late 2008 or newer)
Mac mini (Early 2009 or newer)
Mac Pro (Early 2008 or newer)
You must also have:
OS X v10.6.8 or later
2GB of memory
8GB of available space
Some features require an Apple ID; terms apply.
Some features require a compatible Internet service provider; fees may apply.
Also, you might like to try unplugging any external drives, and backup ones, and try again.

I have an iMac 20 inch early 2009 software osx 10.8.1(12b19)...i am not able to use my internet, outlook, or any messenger. tried troubleshooting, reseting safari, disabling firewall, deleted intego...still no internet

I have an iMac 20 inch early 2009 software osx 10.8.1(12b19)...i am not able to use my internet, outlook, or any messenger. tried troubleshooting, reseting safari, disabling norton firewall, deleted intego...still no internet. i did delete intego without uninstalling so im wondering if that caused the problem. everytime i try to open safari it displays this: Safari can't open the page: "http://www.yahoo.com/". the error is: "the operation couldn't be completed. Operation not permitted" (NSPOSIXErrorDomain:1)

Like nearly all antivirus utilities for OS X, Norton a/k/a Symantec and Intego are worthless junk that will cripple your Mac. Remants of one or both are most likely preventing Safari from communicating.
Search the forums for techniques to eradicate them - simply disabling them or dragging their apps to the Trash is not likely to be sufficient. Start by reading this procedure from Symantec:
http://www.symantec.com/business/support/index?page=content&id=TECH103489
For Intego: http://support2.intego.com/kb/index.php?x=&mod_id=2&id=214
... i did delete intego without uninstalling so im wondering if that caused the problem.
I believe you are correct. Download and run its uninstaller.

IMac (24-inch, Early 2009)でCS6を

iMac (24-inch, Early 2009)でCS6を使っている方おられますか？
CS6の要求スペック（64-bit対応必須）にひっかかるようで、動かない可能性が高い。とサポセンに言われました。似た環境でCS6を使用中の方にお話を聞きたいと思いました。当方、プロセッサ : 2.66 GHz Intel Core 2 Duo メモリ : 8 GB 1067 KHz です。OSは現在10.5.8 ですが、10.6.X まで上げるつもりでいます。

良い情報ありがとうございます。なるほどその方向でやってみます（自己責任で）
1.　10.6 (Snow Leopard)にアップグレード
2.　10.7 (Lion)にアップグレード
CS6をインストール、あわせて他のアプリが64bitで動くか検証
3.　問題なければ、Mountain Lionまでアップグレード
そんな感じで。。早速のレスに感謝いたします。

IMac will not play DVD Movies

I have a first generation iMac G5 (OS 10.4.11) with a "MATSHITA DVD-R UJ-825" drive which plays CD and software DVDs fine, but it will not play DVD Moives, burned or commercial. When inserted, they spin for a minute then I get an error message "The disk you inserted was not readable by this computer." But it should be.
I have tried updating firmware, but the update said I did not need it. Also tried deleting the "com.apple.DVDPlayer.plist" as suggested in an earlier post. Nothing has worked.
I had this problem years ago and have updated the system since but DVDs still will not play. Does anyone know how to fix this or download a new DVD driver?

I do have the exact same problem, but even worse: my superdrive won't even read a software DVD. I would like to upgrade to Leopard (I bought the upgrade DVD) and I can't read it. Is there a way either to make the superdrive work again by myself or use another computer's drive for this purpose (upgrade to Leopard)?
Thank you for your support.

Satellite A40-151 DVD drive will not play DVDs

hi my dvd drive will play music cd's but when i try to play a dvd it just makes a beep and nothing happens i tried windvd and it comes on but everything is blurred and still wont play a dvd

Hello John
Please dont be mad on me but in your posting there is no question or something just small report that DVD drive will not play DVDs.
Anyway, if I am remembering well your unit is about 2 years old and has probably DVD-CDRW (Combo) drive. In my opinion there is no much to do. If the drive has problem with original DVDs I presume that there is laser calibrations problem and the device must be replaced.
I dont know how old is your unit exactly but please check if the warranty is still valid. If yes contact service partner in your country immediately. The drive should be replaced for free. If not you must replaced it on your own. If the drive replacement costs too much I recommend you to use external device (I do it with my old Satellite). On this way I can use newest and very fast super multi DL devices and also create own DVDs.
You can also try to find already used DVD/CD-RW drive and replace it alone. If you need assistance by replacement please write again.
Once again, dont be mad on me. I am ready to write my opinion but it is really annoying when someone write just one sentence and nothing more.
Good luck!

My macbook pro has mountain lion installed and it will not play dvds

my hubby's macbook pro has mountain lion installed, and will not play dvd's. It says it is unsupported, I also have a macbook pro but has snow leopard on it, mine will play dvd's. Please help me, I can't figure out why his won't play the same dvd's as mine.

The most frequent problem in an optical drive is a dirty lens. Use a lens cleaning DVD, a few shots of compressed air in the slot or a fine microfiber cloth (eyeglass lens cloth) wrapped around a business card and gently inserted inside the slot. If no success, the Apple store genius bar is the next stop.
Ciao

I have had my mac book pro for about a year and a half and suddenly my dvd player will not play DVDs and i can not play alot of things on full screen. Does anybody know how i can fix this?

I have had my mac book pro for about a year and a half and suddenly my dvd player will not play DVDs and i can not play alot of things on full screen. Does anybody know how i can fix this?

This could be several things, but let's get the obvious ones out of the way, first:
1. Judging from your text, there's no problem with anything stuck in the mechanism; it's more an issue of no being to put in a disk. In other words, you're sure that there isn't a disk stuck in your MBP. (That happens a lot for all computers.)
2. Go to Applications/Utilities/Disk Utility, and repair the disk. This should take under 10 minutes.
3. Perform the procedure outlined here:
http://forums.macrumors.com/showthread.php?
4. After you're done, leave a message here as to the status of the repair.

IMac (24-inch, Early 2009) Hard Drive Replacement: Hybrid and Maximum Size Question

I have a 24-inch iMac, early 2009 model and the internal hard drive has died so am looking to replace it and also upgrade it in the process.
At the moment the broken internal drive was the standard 1TB model that comes with the computer. I have been doing a little bit of research and I'm liking the sound of a hybrid drive as they seem to be a relatively economical was of achieving close to SSD speeds. I've been looking particularly at 'Seagate ST4000DX001 DESKTOP SSHD 4TB SATA 6GB/s NCQ NAND 8GB 64MB HYBRID' for the replacement. I guess my question is if this drive will work in the iMac. Does a hybrid drive present and problems? Also, is there a limit to the maximum size the replacement drive can be? Will 4TB exceed this limit? Lastly, I understand this drive uses SATA III to connect with the computer, which is backwards compatible (I think?) so I'm presuming this will work in my iMac?
Thanks in advance.

The hybrid drive will kinda sorta be as fast as an SSD. The newest Seagate Hybrid is quite intelligent about caching the most often used files in flash and is quite an improvement over the first iteration. I used both the first and second generation drives in my 2007 iMac and was quite impressed with their performance…until I installed an SSD. The problem with the hybrids is that they just don’t have enough flash and no matter how intelligent the drive is it is guesswork so sometimes you’ll find the drive access just as pokey as any other 5400 RPM drive and then other times very fast.
For about $200 it is a decent upgrade but with SSD prices having dropped nearly 50% in the last 18 months it is worth considering a smallish internal SSD for the OS and applications and an external drive for data.

IMac 20" inch early 2009 Dual Monitor

Hi,
I want to connect an extra monitor to my mac but I'm not sure if I can! Can my iMac use this monitor (http://www.amazon.it/dp/B005OPLG0O/ref=wl_it_dp_o_pC_nS_img?_encoding=UTF8&colid =17NMHEBZB983K&coliid=I1QBI3UDSZPHSG) as external monitor? I'm not sure if my iMac can handle an external monitor with FullHD resolution

IMac 27 Inch Early 2009 freezes periodically

For the last couple of weeks my iMac has been freezing and requires a hard reset to fix. On at least one occasion the screen flashed before it froze.

I have the same problems with my iMac 24" Early 2009 with the Nvidia GeForce GT 120 256MB MXM graphics card. I've done the usual and finally decided that it's a faulty card that only a replacement will fix. Oddly, when I'm home it's more stable when connected via a Displayport DVI adapter to DVI cable to a 24" Dell display. When standalone (like when travelling with my iMac for long stints out of town) it's unusable. It won't run for longer than 30 minutes then I get screen artifacts and freezes and then have to fsck to repair the drive before running it again.
However, I believe that I found the solution. I installed a program which I downloaded after installing XCode called Quartz Debug which has apparently allowed me to disable Quartz Extreme, 2D Acceleration and Quartz GL. I'm not sure which one of these changes has allowed my shaky iMac to run stably now for three hours, including a half hour running a flash game and to play about the same amount of the iTunes download of the movie Avatar, so I'm relatively confident that what I did is working. Both Flash and Quicktime seem to work fine although there does seem to be a bit of screen redraw lag when moving objects on the screen or opening new windows. Other features seem to work fine such as Dock magnification and the Scale and Genie effects.
To disable Quartz Extreme:
Install XCode and then under the XCode menu (the one to the left of "File") click on Open Developer Tool/More Developer Tools...
That will take you to this web page:
https://developer.apple.com/downloads/index.action?name=for%20Xcode%20-
(I don't know if just downloading QD will work without installing XCode, it might)
Select and dowload the package of Applications/Tools called:
Graphics Tools for XCode
Drag the Quartz Debug program to your Applications or Utilities folder. StartQuartz Debug. If you don't get the default tools window open when you start it, look under:
Window/Quartz Debug Settings
. . . and a window will open. You can also hit command-1.
In that menu I made these changes:
Deselected Enable Quartz Extreme
Checked the Disable 2D Acceleration
Checked the Disable radio button under Quartz GL
I am not confident that the settings will persist if I close the program. One website suggested that by forcing quit they will persist, but I'm just not sure. I'll experiment with this later and post again if no one else does. So for now I'm leaving it running and with these settings and no other changes.
I also applied the following changes in Terminal although I'm not sure that it did anything:

So far it's working. I'll follow-up as I have time and once I'm back home.

Macbook pro 13 inch early 2011 WILL NOT go to SLEEP on ITS OWN.

I am able to close the lid to have it sleep, and manually click the apple>Sleep button to get it to sleep, but with the Energy Saver preferences set for it to sleep at 1 minute it will not allow it to sleep. The display will turn off, but the Light doesn't start blinking dimly. Is anyone else having this similiar Problem? I've deleted preferences .plist files etc to try and remove any possible bad seetings but I think it may be related to this error here. I don't know if this problem is via a Firmware update or bad hardware.
I have noticed when I open up preferences for "Energy Saver" the "Console" gives me this error immediately.
