OS X :: IMac Refuses To Sleep After New HD Installation

Mar 26, 2009

My iMac refuses to sleep no matter what sleep preferences I set or even if I try to sleep it manually (apple>sleep). It doesn't do anything. The display doesn't even dim like it used to a week ago. I don't have anything plugged in but the keyboard and regular mighty mouse, and restart doesn't change anything either. The Apple store installed a new hard drive on the computer a few days ago, since the 1.5 year old one randomly crashed and died. So I don't know what kind of funky things they might have changed, I'm just wondering if there's any simple maneuver I can do to make it sleep like it's supposed to!

QuickTime :: Pro 7 Refuses To Launch Independently After Installation Of AVID MC7 / Sorenson Squeeze

Apr 17, 2012

After installation MC7 and Squeeze, i can no longer launch QT / QT Pro. The only way i can play .mov files is via iTunes, which for me is less than desireable. So the codec is obviously there. 

Please note that QT 7 (non pro) was working fine prior to installing Avid & Sorenson. 

I've tried 'repairing' QT by downloading the file, but even after the repair it still refuses to launch. 

Also, QT is non longer listed in the 'open with' options..

OS X :: G5 Refuses To Awake From Sleep?

Nov 13, 2009

Running OSX 10.5.8 (plain vanilla installation) when I select "Sleep" it will not awake from sleep. This is on my G5 tower.

Running OSX 10.5.8 (full custom with lots of software)... my system will not remain in Sleep mode for more than 1-2 seconds (re. my previous recent post on this forum... [URL]

Since it will sleep with a minimum installation any ideas on how I can get it to awake from sleep without having to do a hard restart?

If I can get it to awake... then I can trial-and-error it to find out what software is preventing it from going to sleep.

MacBook Pro :: Taking Ten Minutes To Boot And Refuses To Sleep

Nov 6, 2010

Yesterday, I had some issues with my MacBook Pro, the keyboard and trackpad were unresponsive (I tried a USB Keyboard/Mouse, didn't fix the problem), it took 10+ minutes to boot up, and it refused to wake from sleep. So I did some hunting, found out if I removed the FireWire kexts, then that would solve the issue. I removed the kexts, and rebooted it, and everything works perfectly fine, with one exception. Both FireWire ports are undetected and inoperable. Would a OS reinstall fix this, or is it some deeper issue that may require a logicboard/hardware component replacement?

MacBook Pro :: Slow Booting And Refuses Sleep Mode

Aug 6, 2009

My MBP (about 2 years old, Santa Rosa) is having some major issues both starting up and going into sleep. First off, I'm using 10.5.8, everything's updated, I don't have a bunch of stuff on the startup processes (quicksilver and iTunes helper) and I'm plugged into a power source. When I start my computer (since yesterday) it has been taking an abnormally long time at the grey screen before the Apple, the grey screen with the apple and the rotating wheel, and then it goes to a light blue screen for 5 or so minutes (repeat: minutes) until flashing light and dark blue and finally taking me to the login. Not only that, but my computer will not go to sleep when I close the lid. Instead, the screen turns off and the hard drive and fans keep chugging. What's more annoying is when I then try to open the lid to manually turn it to sleep, the screen won't turn on. This usually requires a hard reset, which then takes 10 minutes to start up.

PowerPC :: IMac With G4 Processor Refuses To Boot?

Dec 11, 2008

I just bought an iMac with a G4 processor from a friend... The only problem is that apparently some vital file was deleted and as a result, it will not start up. I have a Tiger recovery disc, but because I'm only being shown the gray apple screen and the loading circle, I can't actually use it. Any ideas?

I own the latest version of an iMac, and my sound refuses to work.However, when I start the computer up, it makes the long noise just before the gray pages with the dark gray apple comes up.

IMac :: OSX Boot Drive Corrupted - Trash Refuses To Empty?

Nov 9, 2010

1. I do occasional maintenance with onyx and have been getting a few startup disk errors in recent months. These seem to get repaired and the computer still functions as normal. I have never had these before in 8 years of using osx so they do worry me. Is the osx boot drive just a bit corrupted? Would a simple reinstall help or is the hd showing signs of failure?

2. The trash simply refuses to empty. The operation can�t be completed because you don�t have permission to access some of the items.

I've tried to bring the items back to the desktop and the folder they came from but they simply make a copy of them. I've tried the option key method and sudo rm -rf ~/.Trash + sudo rm -rf /Users/user_name/.Trash in the terminal but get no change

IMac PPC :: Imac G3 Installation Of Tiger Cd Won't Boot?

May 14, 2012

I have the CD version of tiger and am trying to install it to a recently purchased iMac G3. The Installer installs disc 1, resets, but doesn't boot up to install disc 2, it simply asks again to install disc 1. The Mac for some reason will not boot from the installed software and therefore I cannot complete installation. Can anyone figure out why the mac refuses to boot from the HD in order to install disc 2?

IMac :: ATI 4850 - Old Leopard Installation

Apr 15, 2009

this is my first posting but I am desperate and need some help Apple could not provide. Here is my situation:

- new iMac 9,1 2,93 GHz, 4 GByte, ATI Radeon 4850
- pre-installed OS: Leopard 10.5.6

I have access to a MBP and an older iMac. The MBP had a defective logic board some months ago so I decided to copy its content (after repair) to an external hard drive. I used this hard drive as my primary OS and used it with the MBP or iMac and did have the same data all the time - excellent time-saver for me. Now the new iMac was shipped yesterday. I tried to boot it from the very same external hard drive as well. It worked but there are some annoying facts I need some help to deal with: I cannot activate sleep mode with the new iMac. The graphics card seems not to work well: stuttering screen saver, slow high definition video playback, slow spaces etc. I cannot dim the monitor's backlight with F1/F2 keys nor the monitor setup. All these problems disappear when I boot from the internal HDD but that is not an option for me. It looks like the "old" Leopard installations lacks of some drivers. Is there a way to add them, is there another solution or will an update of Leopard 10.5.7 - at least most likely - solve the problem? Apple support did not feel the need to help for "exotic configurations". I was told a fresh installation of a retail Leopard copy on an external hard drive COULD work (no guarantee) but it would take me too much time to re-configure and I don't feel the desire to set up my system fresh and new like in old Windows days.

OS X :: Case Sensitive Installation On IMac

Dec 10, 2009

So, I just received my iMac and after playing with it for a few weeks I find that I don't like the fact that it was shipped with a case insensitive install. I was hoping I could simple run some command to convert, but there doesn't appear to be any "easy" way to do this. I assume I can simply reinstall and as part of the install format the drive case sensitive.

My questions are as follows:
1) Is a reformat/reinstall my only option (not a problem but I though I would ask)
2) I don't expect Mac OSX to have a problem running in this environment but if someone is aware of any restrictions I would love to hear it.
3) Would this have any effect on my plans to install Windows 7 via bootcamp? (once it's supported that is).

Software :: Windows XP Installation On My New Imac?

Dec 23, 2009

I have recently purchased a new Imac (OSX 10.6.2), and I want to install Windows XP Home edition on it using Boot Camp. I have already installed Windows on another computer, my older Macbook, and my question is this - can I use the same Windows installation disk and activation code for my new computer? I have read that one Windows XP disk is good for just one activation; do I need to uninstall it from my macbook in order to be able to install it on my Imac? Is that even possible?

I am thinking of sending in my Mac Mini to OWC because I'm not good with the insides of computers. I am wondering how the Service works.

IMac :: New 27" Imac Takes Ages To Go To Sleep?

Aug 15, 2010

just purchased a new 27" Quad core i5 and it takes about 5 seconds for it to go to sleep, and then makes a loud noise after.

My hard drive is also noisy, it whines and drums constantly.

I also have got yellow tint on all sides of the screen.

I live in NZ so if i will not get a new replacement, instead it will be sent away to apple which will take forever

by the way it is the older 27" (late 2009) version.

OS X :: IMac 2007 Aluminum RAM Installation - Get Black Screen With 2 Gig Stick

Sep 8, 2009

I bought my aluminum imac when it was released in late 2007. I had a 1 gigabyte stick up until now, but I decided to upgrade to 2x2 gigabyte sticks. When I took out the 1 stick and placed the new ones in, my computer would sound like it turned on, but the system really did not boot up. I have tried many configurations to see what the problem with the RAM is, and all I could figure out is that the computer will only boot up if the original 1 gig stick is in one slot. I checked both sticks with this, and they seem to register on my mac when I check the "About This Mac" section. Basically, I get a black screen if I use only a 2 gig stick, or both 2 gig sticks. I can have a maximum of 3 gigs so far, but I really would like all 4 that I paid for. I'm not so sure that it's a problem with the ram, especially because it is recognized by the system, but it can't boot up the system, so I am simply dumbfounded. Anyone have an idea what the problem is? I just recently installed Snow Leopard prior to getting the RAM if that has any importance.
