Core Duo Mac Mini - NO Sound issue

I have a Core Duo Mac Mini and I have an issue where my sound doesn't work in various applications including iChat (interface sounds of iChat only; audio for chats works OK), Windows Media player & Flash Player.
While re-booting SOMETIMES restores the [interface] sound to iChat, the same cannot be said for WMP & Flash players. I have uninstalled Flash Player and reinstalled the beta universal application from Macromedia and I still cannot hear any Flash based sounds.
Even when I have no [interface] sounds in iChat, I have normal system interface sounds such as alert sounds and volume level alert.
Anyone running an Intel based Mac have similar issues?
Thanks!

  • Core Duo mac mini vs. Core 2 Duo iMac

    I am interested in getting a new mac. I would like some advice from others about some of the new models. I do a lot of iPhoto with my Nikon D50 and iMovie and iDVD. I am assuming that a new Core Duo mac mini will be a significant upgrade from my current G4 mini, but I am wondering how much more performace I will see by getting a Core 2 Duo iMac. I am just not sure if I will notice the increased L2 cache or the better video card. again, there is nothing professional, but would like good performance. I am currently using a 19" Dell monitor that I am happy to keep, but will unload it if I get the Imac - not a problem.

    The Core Duo Mac Mini lacks the graphics processor, and the RAM upgradeability of the iMac. Also it lacks the Firewire 800 you can get on the 24" model, and the larger hard drive capacity you can get on the iMac build to order. The Mac Mini internally can only get up to 200 GB internally, and with build to order, 500 GB can be put in the 17" and 20" iMac, and 750 GB in the 24" iMac. You'll find hard drive capacity a must in movie production, and the speed of the hard drive will be better. I'd even partition that hard drive to keep space for temporary files on movie projects. No need to get rid of your Dell display when getting the iMac as the iMac supports dual-display with a stretched desktop across both displays! Apple claims a 39% increase in speed for the MacBook Pro Core2Duo which was just released over a similarly configured MacBook Pro CoreDuo. Since iMovie and iDVD will be able to take advantage of the processor, I'd go for the Core2Duo in a heartbeat.

  • Will iTunes 10.7 play my 720p HD movies on my Core Duo Mac mini that are currently on my iTunes movies playlist and playing perfectly fine in iTunes 10.6.3?

    Will iTunes 10.7 play my 720p HD movies on my Core Duo Mac mini that are currently on my iTunes movies playlist and playing perfectly fine in the older iTunes 10.6.3?
    Please let me know so I do not update to iTunes 10.7 and lose the ability to playback my 720p HD collection from my Core Duo Mac Mini to my Apple TV.
    In the requirements it says:
    • To play 720p HD video, an iTunes LP, or iTunes Extras, a 2.0GHz Intel Core 2 Duo or faster processor and 1GB of RAM is required.

    Performed the AppleTV update yesterday.  Haven't had a problem since...though it's only been one day.  Am I just hopelessly optimistic to think that AppleTV just needed to be updated to match iTunes and iOS for home sharing and airplay?
    Fingers crossed...

  • Is the superdrive in the Core duo Mac mini and the G4 mac mini the same ?

    I have a G4 mac mini with a busted super drive and someone is selling a core duo mac mini with ram and a super drive but a bad logic board.
    Is the super drive the same in both machines ?
    How tough is it to swap it to the other ?
    I've done some Hard drive installations and ram installations using the macfixit guide but don't want to bust it I'm certainly not Mr Fix it.
    Thanks in advance.

    They are not the same.
    Compare the PowerPC Mac Mini specs from Archive.org:
    "Optional SuperDrive (DVD±RW/CD-RW): writes DVD-R discs at up to 4x speed, writes DVD-RW discs at up to 2x speed, writes DVD+R discs at up to 4x speed, writes DVD+RW discs at up to 2.4x speed, reads DVDs at up to 8x speed, writes CD-R discs at up to 16x speed, writes CD-RW discs at up to 8x speed, reads CDs at up to 24x speed"

  • Aperture 1.1 on core duo mac mini...

    Hi -
    I'm wondering if anyone knows if the universal binary version of Aperture will run on the Core Duo mac mini with the Intel graphics chip...
    Thanks,
    Dan

    Hi -
    I'm wondering if anyone knows if the universal binary
    version of Aperture will run on the Core Duo mac mini
    with the Intel graphics chip...
    I don't think it is supported, but some of us are going to try and see how it works. I'm not expecting much though as Aperture relies on the video card more than anything for performance, and the Mac mini video card is much weaker than the ones in the Macbook Pro or Intel iMac.

  • Will 1.86ghz Intel Core Duo Mac Mini run the IPhone SDK?

    I kinda asked this as a follow up in another thread. But I really should have asked it in a separate thread here.
    Will a 1.86ghz Intel Core Duo Mac Mini run the IPhone SDK?
    Additionally, it comes with 10.4 and IPhone needs 10.5.4 or better. Can I download and upgrade to 10.5.4 free from Apple or will I have to purchase the upgrade?
    Jerry

    The hardware is more than sufficient. You will have to buy 10.5 (Apple does not have upgrade pricing).

  • Core Duo Mac Mini video lag?

    Hello all my name is Jose I recently acquired a 2006ish Mac Mini that my friend gave to me that has a Core Duo T2300 1.66Ghz processor, Intel GMA 950 64MB of video memory, and 2GB of RAM. Its connected to my 46" HDTV and is being used as HTPC for Youtube and a bunch of other things. My problem is that the other night my mom wanted to watch her favorite spanish tv show on Univision.com and once I entered full screen whatever we were watching became choppy and laggy. My Flash Player Version is up to date (10.3.183.5) and I can watch Youtube videos like Top Gear in Full HD (1080p) that don't lag what so ever, video is silky smooth. So what do you guys think is up with it?  You're guys help is greatly appreciated thanks in advance.

    If you open Finder and click on your home folder, the one with the little house for an icon, you should see listed all of the folders in your home folder.
    You should see a folder called Desktop, which contains everything on your Desktop.
    If you left click on Desktop to high light and then depress the Command + I keys that should open a pane with information about your Desktop folder.
    Please let us know what it says for the Size:

  • Increase fan speed on Intel Core Duo Mac mini?

    I have owned a PowerPC G4 based Mac mini for some time now. It's been (and continues to be) a great little computer.
    Just recently I bought the Intel Core Duo version. It too seems like a great little computer.
    However, I've got to admit that the amount of heat the Intel version puts out is staggering. The internal hard disk claims to be running around 119-126 degrees Fahrenheit. I put a thermometer near the vent on the back and it topped out at 120 degrees F. The bottom pad is nearly too hot to touch. This computer is running a distributed computing project.
    Far be it from me to second guess Apple's engineers, but the fan is never turning very fast at all on the Intel mini. It is running, though, and appears to be doing as it was designed to do. (I've seen my PowerPC machine get to rip-roaring during the summer.)
    Running the Apple Hardware Test shows that the Intel mini's fan can speed up quite a bit. I'd like to know if there's a way to request a higher fan speed outside of the Hardware Test. I know I could pop the thing open and just "forget" to reconnect the fan speed sensor wire to command the fan to run at full speed, but I don't want to invalidate the warranty.
    Maybe I'm being silly, but I prefer that my computers be moving enough air from them to keep things cool regardless of noise level.

    The smcFanControl utility is what ended up solving this problem. Turning up the fan speeds just a little bit resulted in a very noticeable cool-down.

  • Frequent Kernel Panics w/ core duo mac mini

    I have been having kernel panics left and right. It's random... meaning it seems to happen whenever it wants to do anything er.. out of the ordinary.
    - It's crashed on me frequently when trying to view the dashboard
    - It's crashed on me frequently after using Front Row
    - It's crashed on me when it wants to sync with .Mac
    - It's crashed on me when opening System Preferences
    I think for the most part, I'd like to say that the crashes happens when it's waking up a hardware device or the sort. Of course, that's just pure speculation at the moment. Otherwise, it's obviously not so random frequent event.
    It rarely crashes, if I open all these apps, close it, and do multiple tasks. The symptoms seem to be more like i.e. The system has been idle for a while, I suddenly call on the dashboard and Wham!! kernel panic.
    In another case, the system is rather idle. I decide to check out system preferences. Again, a kernel panic.
    .Mac wants to sync after the systems been idel... again kernel panic.
    Anyway, in short, it seems so far this kernel panic happens after the system has been idle for a while.
    Mac Mini w/ mini-optical sound out connected, display is hooked via DVI to HDMI cable, USB 2.0 external hard drive connected, Bluetooth wireless keyboard and mouse, and a digital cable box connected via Firewire.
    So, why all the kernel panics? Anyone else having frequent kernel panics.

    Here's are the last three entries in the panic.log.

  • Bluetooth Error on early 1.66Ghz Core Duo Mac Mini model.

    Something really weird that wasn't really happening until a couple weeks ago... I can connect to a bluetooth enabled cell phone just fine... I can even transfer some small files back and forth okay, BUT... if I attempt to transfer something big, like a music file... a 3MB mp3 per say... it will start the transfer and after a few seconds, sometimes longer... the error comes "The Hardware bluetooth is no longer available" ...
    NO CLUE!!!
    Anybody around having the same problem or had maybe?
    Thanks a lot and PEACE!
    Gui.
    Mac Mini 1.66Ghz Code Duo, 160Gb SATA, 2Gb SODDIM   Mac OS X (10.4.8)  

    If this mini was bought new in May 2007 it is still under warranty, and you should contact Apple. If you have an Apple store in your area you can make an appointment at the Genius Bar and have it looked at. If not, then simply call Apple and describe the symptoms. If they can't walk you through a series of troubleshooting steps to identify and resolve the problem, they'll arrange for the system to be returned to them for service. You don't have to put up with a defective drive.
    On a broader note, it's not likely to be your media, as long as you are trying to use good quality blanks rather than a low-cost generic brand. You might try a good quality blank from a different manufacturer to check however.
    Also, you mention 'Disco' and 'Toast' - which implies you have installed alternative CD buring software on the system. Nothing wrong with that, but make sure these applications are properly compatible with your version of MacOS, and the system - particularly that they are Intel-native copies. A problem with third-party burning applications could cause the symptoms you describe.

  • Has anyone run Maya 7 on their MacBook Pro/iMac Core Duo/Mac Mini Core Duo?

    Hi,
    I plan on getting a MacBook Pro to replace my Powerbook 1.25 GHz.
    I cannot find any info on a universal binary for Maya and was just wondering if anyone has actually tried it on an Intel based Mac.
    If so, how is it? Is it like a G4, faster/slower? Does it even install?
    I tried looking in these forums and the rest of the internet but couldn't really find anyone who has actually got it up and running on an Intel Mac.
    Also, probably worth noting that the only other PPC apps I have tested on a MacBook Pro that are quite resource hungry are Cinema 4D, another 3D app that still takes advantage of dual processors even under rosetta and Google Earth. Both of these apps actually run quite a bit faster than my PowerBook and the universal binary version of Cinema 4D is breathtakingly fast.
    Navigating around Google Earth esp. with 3D buildings turned on in New York is very smooth in contrast to the "choppy-ness" of my PowerBook.
    Any real world feedback would be superb,
    Thanks in advance!

    this is from creativemac.com and their 3d benchmark article
    Autodesk Maya
    Our Maya tests are also pitiful for the poor MacBook. Maya, like LightWave, has not yet been ported to Intel hardware for Mac OS X. It lost out in every single test to every other piece of hardware. However, if you look at the results of the slightly more powerful MacBook Pro, you can see the potential for Maya on the 13-inch MacBook once it is finally ported.

  • Will iSight work with Intel Core Duo Mac Mini?

    yes yes yes yes yes. it will work. but not need to make yourself feel stupid

  • Brand New Mac Mini HDMI Sync Issues

    I just purchased (as in 3/29/13) a late 2012 2.5GHz 500GB hard drive 4GB RAM Intel Dual Core i5 Mac Mini MD387LL/A. It is connected to a 27" Samsung B350 S27B350H monitor via HDMI to HDMI.
    I was excited to set it up. I was downloading the 10.8.3 update as I had read about the flickering problems. In the middle of the download the computer went to sleep. Upon waking the monitor flickered badly then went black. Like it was not receiving a signal.
    I powered the monitor down, and turned it back on. It had a display for about two seconds then went black again. I tried this several times with the same result each time.
    Finally the update to 10.8.3 was complete and....the problem persisted.
    I decided to see if it was the cable or the monitor. I connected the monitor directly to my Xbox with a different HDMI cable and it worked perfectly. So I switched to the original HDMI cable I used with the Mac Mini, again it was perfect!
    Upon reconnecting the monitor to the Mac Mini it was working again...for about an hour now the problem is back.
    I am completely frustrated and disappointed.
    Suggestions?
    Or do I just return the Mac Mini for a different one?

    Were you able to get your display working? I have an LG 27" at home connected to a Mid 2012 (June) MacBook Air 13" that has absolutely no issues. However, I just obtained the same Samsung monitor you have and appear to be having the same issue.
    The only solution that I have found is to unplug the power from the back of the monitor or at the power supply each time my computer either wakes from sleep, screensaver, or a display that is powered off. This seems to be true via the following connections:
    1. HDMI to DVI thunderbolt adapter
    2. HDMI to Thunderbolt adapter
    The display powers on with a slight flicker and then will immediately stop displaying the image on screen. What's especially strange here is the MacBook Air still believes the display is connected -- my login screen or active apps that are displayed on the external monitor do not move to the MacBook Air display as if it's no longer connected.
    I hope someone has a solution to this issue! Thanks!

  • My Macbook Pro with 2.16GHz Intel Core Duo (Mac OS X v10.4 Tiger) can convert to Lion?

    my Macbook Pro with 2.16GHz Intel Core Duo (Mac OS X v10.4 Tiger) can convert to Lion?
    Toyoo

    These are some of the most common Questions (Q) and Answers (A) about Lion:
    Q: What are the system requirements of the Lion upgrade?
    A: Core2Duo, Core i3, i5, i7, and Xeon Intel CPUs with 2 GB of RAM in a Macintosh computer with 2 GB of RAM, and 4 GB (7 GB after installed) for downloading from the Mac App Store (Available in 10.6.6 and later). Unofficially, past upgrades have arbitrarily also required an additional 15% of the hard drive to be free for data.
    Q: What applications are compatible with Lion?
    A: http://roaringapps.com/apps:table provides a nice third party editable listing for people to include the compatible applications. Many of these compatibility entries came from before Lion's release. Please verify they are correct now that it has been released, and help edit it for more accurate data. Be sure to include any update version of Lion post release that you have found is or is not compatible with it, for the help of others who may be upgrading to Lion the first time. Additionally, as it was released, there is no Rosetta. This means any application that is stated to be PowerPC in the System Profiler, will not work with Lion, and needs a comparable application or upgrade to be compatible. The System Profiler is in Apple menu -> About This Mac -> More Info. Intel and Universal applications are on the whole supported, though may still need some tweaking before every feature is compatible.
    Q: Are there any pitfalls to watch out for?
    A: With all upgrades, backing up your data at least twice has been a given. Hardware can fail independently of downloads and upgrades, though may happen simultaneously. Software may be found to be incompatible that has not been tested with the new upgrade, or combination of other software that might be installed with the upgrade. It is also strongly recommended once your backup is complete, to shut down your computer, remove all but Apple wired keyboard and mouse (notebooks remove all input devices). Then once done, reboot, and go directly to the upgrade distribution system available. Third party system tools, modification, and "maintenance" applications should be verified as compatible, or removed until known to be compatible. Check with developers how to remove if it is essential to use Lion before those applications become compatible. Most "maintenance" tools that deal with system cache, prebinding, are not really maintenance tools. Ask on forum when are the appropriate times to use them before assuming they should be used for upgrades or otherwise.
    Q: How can I get from 10.4 or 10.5 to 10.6.6?
    A: Purchase a 10.6 retail installer from an Apple retail or third party reseller. It has a picture of a Snow Leopard on the DVD, and does not say Upgrade, Dropin, or OEM. Install it, and then install the 10.6.6 combo update from:
    http://support.apple.com/kb/DL1349
    Q: Is it true that I can only get it from the Mac App Store?
    A: Presently this truth is based on current documentation as of the writing of this article. It may change, but we can't speculate as to its change. It has a better chance of changing if users request something different at:
    http://www.apple.com/feedback/macosx.html
    Q: What limitations might one encounter if it doesn't change?
    A: First off the 7 GB space limitation on the hard disc after it is installed. Secondly, the size of the download file requires significant time, unless you have a high speed broadband connection. Times expected are below -
    4 GB at:
    5Mbps is 2 hours.
    at 1 Mbps is 10 hours.
    at 384 kbps is 27 hours.
    at 56k kbps is 184 hours (nearly 8 days).
    If you include the 10.6.6 combo update of 1.06 GB
    add 29 minutes for 5 Mbps
    145 minutes (2 and 25 minutes) for 1 Mbps
    6 and a half hours for 384kbps
    A 24 hour day and 15 hours (for a total of a minimum of 39 hours) for 56kbps
    Remember the retail 10.6 currently does not include the App Store, and those upgrading from 10.5.8 or earlier will need to both buy the retail 10.6, and download the combo 10.6.6 update, not to mention ensure they have the correct processor and 2 GB of RAM. Finally once it is available, you'll have find out how long approximately it takes to install after the download is complete.
    These times do not include installation time, which on a MacBook Pro 3,1 15" installing on a Firewire 800 Newertech Voyager with WD10ACS-322J80 drive, 10.6.7, took 1 hour and a half to complete the installation from double clicking the install command to the registration screen. These times may vary by connection speeds from a non-dedicated connection, or background application usage of the internet. Any applications running when the installation process begins might interfere with the installation itself, and they should be quit first.
    The installer just before it starts has in its package contents an InstallESD.dmg file a DVD burnable image to install on additional computers in the home without downloading over again. So if you desire to reinstall without an extra internet download, extract that file, by selecting the installer in the dock, and control-clicking it, and revealing it in the Finder. Next Control-mouse click it, and select show package contents. Inside that folder is a Shared Support folder. That's where you find the DMG.
    Q: If I purchased a Mac recently, can I get it cheaper?
    A: Yes, visit http://www.apple.com/macosx/uptodate/ for details.
    Q: When will Lion become available?

  • Do you have 256 MB Intel core due mac mini?

    Hello Users
    I checked "about this Mac" after installed OS X cd. I could not believe what I'm seeing the hareware overview as follows:
    Hardware Overview:
    Machine Name: Mac mini
    Machine Model: Macmini1,1
    CPU Type: Intel Core Duo
    Number Of Cores: 2
    CPU Speed: 1.66 GHz
    L2 Cache (shared): 2 MB
    Memory: 256 MB
    Bus Speed: 667 MHz
    The Memory does recognize just 256 MB, not 512 MB.
    Please tell me any reason of this problem and solution if you have. Of course this mac mini is very very new one.
    Intel core due mac mini   Mac OS X (10.4.7)  

    Welcome to the Apple Discussions!
    I would call AppleCare Support in your area. Clearly, your RAM is not being recognized correctly. Since your computer is new, Apple may need to service it and replace the RAM. Apple buys components, like RAM and the hard drive, on the open market and the RAM you have could be from one of several different vendors. It's possible that the chip you have is defective.
