Mac Pro :: Not Reading Any Discs - Make High Pitch Sound And Eject
Jul 14, 2008
I just purchased a mac pro about 4 months ago and I love it, I have never had a problem with it until today, I went to install a new program on it and it did not even read it, it made a hi pitched sound for a short time then stopped, waited about 10 seconds did the same thing. After a couple times of doing this it would eject the disc, so I figured I would try another disc, I have tried many different discs such as games, cds, programs and nothing has worked.

I have this high pitch sound that started intermittent this morning .
Now it's getting more frequent and last longer.
It just stopped when I moved the power saver setting of the video from never to an hour.
I'm not sure where it's coming from yet.

My wife has a PB G4 15". No matter what kind of disc is put in the drive, it gets spit out about 3 seconds later. Also, we have a 120 GB external HD that works just fine with our eMac, but no joy with the PB.

Whenever my screen is not turned up to the maximum brightness, a really high pitched sound is emitted from the laptop. If you've ever heard the "mosquito ringtone", that's basically what it sounds like. Really odd. It's definitely got something to do with the screen brightness, and I basically can't use my laptop at medium brightness because the sound drives me a little nuts. Turning the brightness to the lowest setting makes the sound less intense, but it's still audible.

I've noticed on my MacBook Pro (late 2013 with retina, 13", 2,4GHz i5, 256GB SSD, 8GB Ram) that when I run the display on low brightness, there is a high pitch noise coming from the screen (inverter problem)? It seems as it disappears when adjusting to either a high brightness or turning it to zero.
Info:
MacBook Pro with Retina display, OS X Mavericks (10.9.4)

I just bought a pair of the Rokit 5 external speakers. When I plug them into a Mac Pro (Tower) I get a high-pitched hum from the speakers each time I try to play a sound. So if I go into System Preferences/Audio, and I try to play a sound, the high-pitch is heard as the sound plays, and for a second or two after, then it goes away, and is heard again each time I try to play a sound. Same with when I play something thru iTunes or any of my audio apps.
If do the exact same thing playing from a Macbook, I do not have that problem at all, the sound is nice and clear with no high-pitch sound.
I have the speakers plugged in using 1/4 inch jacks to an external sound card (MBox), and this audio card is plugged USB into the Mac.
Info:
Mac Pro, Mac OS X (10.6.8)

Hey guys, got a little issue here. I have had a MBA since about march of this year. Just recently I on two occasions the computer has all of a sudden had this loud high pitch whine. It has only happened twice and at both times (if I remember the 1st time correctly) I wasn't really doing anything on the computer. Today specifically it was just sitting idle on my desk. Not sure where its coming from maybe speakers? Any idea to what this is? Should I be setting up an appointment to see a Mac Genius?

When I turn it on it runs fine for sometimes about a minute (sometimes less) before it just turns itself off! After it turns itself off I'll hit the power button and it emits a high pitch squeal from the machine whilst holding the button. If I then remove the battery from the Machine depending on how long I leave the battery out and put it back in, it will then power up for a short amount of time. Sometimes I can get it to the desktop and open System Profiler for example, other times it gets as far as the Apple grey screen. I've ordered a power adaptor as I didn't get one with the machine but as far as the battery indicator goes, it's on 96% and all four green lights are on the battery indicator on the base. Has anyone heard of any problems like this before?I believe it's running a 500mhz processor and has 512mb of Ram.

I have burnt a dvds on macbook pro3,1 running OS10.4.11.[large picture files, jpegs and tiffs which work a treat on lap top] when I put it in mac pro1,1 running OS10.5.8 it shows as a blank disc. Eject and re-enter it a few times and it might recognize it but it might not. check it in lap top and its fine. This happens with a variety of disc types, and sometimes it is fine.

Why dont you post the explanation for certain MATSHITA DVD-R UJ-857 superdrives not being able to read: dvds/ cds/ blank dvds/ blank cds/ burned dvds/ burned cds or a combination thereof?
Apple's firmware 2.1 update released late june 2007 unwittingly fried many superdrives functionality and apple pulled the firmware update as soon as the buzz on the internet took hold, but not before many drives were randomly zapped.
Unfortunately it seems that apple doesnt publicly admit any problems on their website, in the hope that users will not notice the loss of functionality (my drive cant recognise blank/burned media, but published (pressed) dvds and cds are recognised, hence one doesn't notice there is a problem at first).

I have a new 27" I7 that appears to have the high pitch sound issue if the brightness is not at max or lowest. How "common" is this issue?
I do not need the perfect iMac (I have some gray banding and the 1TB HD grumbling and it is not a big issue to me) I just wanted to see if this high pitch noise is considered a defect and needs to be fixed/replaced or it is more common than not with the iMac.

I placed a Hoyle card game disc into my Mac Mini and it does not seem to be reading the disc and now I do not know how to get the disc to eject. Before I just had to click on the eject icon at the top of the screen but it only says super drive in light grey. How do I get a disc to eject?

I have noticed a lot of disk activity reading and writing, it maxes out in bursts up to a couple of minutes at a time and overall seams to be reading and writing a lot of the time, with no processor activity at all. There is no obvious culprits in the activity monitor but terminal displayed large number of read and writes for mds, but spot light is not indexing (no dot in Mag glass) and this has been happening from months now.
Possibly longer noticed it when recieved replacement drive due to crook seagate, may have been doing this but could not hear it. Running last Snow Leopard on iMac 27 mid 2011 i7 custom with 8 gb of ram. also should note this unit has had load of issues Bad Ram, some software problems would not sleep (software) none of which have ever manifested on any of my other (older) macs. Also have noted that this drive activity does seem to coincide with using safari on occasion??

iMac (27-inch Mid 2011), Mac OS X (10.6.8)

I just bought an iMac 24" 2.8Ghz Dual Core, 2Gb RAM, 320 HDD. This nice iMac has been with me only 2 days and the problems already started. I don't know why when I play a song either in iTunes or in web(audio streaming) the audio suddenly changes. It's as if you applied an EQ and removed all the low frecuencies and after a few seconds the sounds returned just as normal. When this "auto EQ" happens, the sound becomes "brighter" (I hope you understand what I am trying to say) but just as I said, after a few seconds, the sound is played normaly. I am running Mac OS X v 10.5.2.

I have a 24" aluminum iMac G5. I have never had a problem with sound before, and feel like this problem is isolated to a certain DVD but the DVD works on EVERY other player I own. Everything pretty much plays DVDs, so that's many!
So here's my problem: There's parts of this movie that have very high pitched sounds, like electronic sounds that are just sound effects in the movie. Whenever I get to those parts in this movie (maybe even other movies for all I know, I don't play many) and the sound goes quiet, like the speakers can't handle that high pitched sound.
I feel there must be something I can do about it, right? I just use the regular default DVD player application that pops up when I put a DVD in. I tried playing with that equalizer but nothing changed. Any ideas...?

I've got an iMac 233 and I'd like to reinstall OS 9. My only problem is that I don't have an install disc. Can I make one i.e. with the system folder or something? Also, the optical drive is a bit flaky so could I install from a flash drive or external HDD?

I have an old G4 system with Pro Tools recording software and related Plug-Ins installed and running flawlessly. Bad news is that the drive is about 9 yrs old and I want to make a backup before selling it to someone so they can have a bootable backup drive instead of having to re-install the whole system if the internal drive craps out.
The OS is 9.2.2. It is not classic and has no version of OS X on it t all.
How do I make a bootable clone of the whole system discs, apps an all, to an external firewire drive?

I have older OSX versions that are on disc in addition to some older software. I want to have these files stored for when I need to make another boot disc or an install. I want to have them as .dmg files. I guess that is the default that you can open on OSX, add the serial number and install?
Can I use the OSX operating system to make these? I also have toast 11. Can I do the same thing?

iOS 7.0.6

When I am watching shows in high definition, I am not getting high definition sound out of my Mac mini. I have my Mac mini connected using an HDMI cable. I would think that I should at least be able to get Dolby 5.1, but right now, I'm not getting any high definition sound at all.

When I connect to an HD TV using the Mini DisplayPort (via a Monoprice Mini DP-DVI dongle and a Monoprice DVI-HDMI cable) and to a Hi-Fi system using the headphone out, the Hi-Fi speakers emit a loud and persistent high-pitched whine.The whine disappears when I disconnect the Mini DP dongle, and also when I disconnect the audio cable so that the sound is playing through the internal speakers. There's no whine when I connect earphones to the MBA instead of the Hi-Fi. I don't have another external display with which to test the issue, so I'm not sure if this sound exists when the computer's connected to, say, an ACD.I'm surprised that this problem doesn't seem to have been mentioned on this board, but it's well documented on the Apple boards (1, 2, 3, 4). The consensus over there is that it's a fundamental design flaw in the MBA and that the only solution is to get a ground loop isolator. Has anyone here had the problem and been successful in getting it fixed by Apple?
