My iMac stayed with grey screen after power on. It repeatedly booting when I try to boot from the Mac OX install Disc.

After I run bootcamp and try to install WinXP.
I can't boot up from any system.

Reboot and hold the option key down, choose OS X on your boot drive and set the System Preferences > Startup disk to OS X.
You can't install XP on a Mac, Apple only supports Windnows 7

Problems with Booting from the Snow Leopard Install Disc

I need to do a reformat of my iMac drive and reinsall Snow Leopard. Then I want to run System Migration and move the contents of my Mac Pro (running Snow Leopard) over to the iMac.
I placed the retail Snow Leopard installation disc and held the "C" key down during restart. My optical drive make a bit of random noise and eventually ejects the SL disc. I've tried a CD, movie dvd and another software program installation disc and none of them seem to be able to be read. I've sold the Mac Pro and am in a bit of a bind as I need to get this done and shipped out. I'm also going to have to wipe the Mac Pro drives clean and do a reinstall of Snow Leopard.
Can anyone help?
Thanks,
John

Do you have the original install discs that came with the computer?
If you do, try powering up the mac pushing in the disc and hold the OPTION key, which will bring up the start up manager, select the insrall disc to boot from.
After booting, select the language, on the next page go to the menu bar and select Utilities/disk utilities, select your volume (default name is Macintosh HD, or what ever you ma have named it) First aid tab, run verify disk.
If it comes up with errors (they will be in red font) click repair disk. Rerun this till it it comes up with "this disk seems OK i(n green font)
Then quit the installer and eject the disk.
Try the Snow Leopard disk using the same proceedure (power up, push in disk, holding the OPTION key) to boot to the start up manager, and select the SL disk, and do a clean install.
Make sure that you have a retail install disk (white SL on it)
You can try this from the retail SL disc, if you do not have the Original disc(s) you should include all of them to the person you seel/give it to.
After install, follow these instructions.

Two Macbook pros circa 2009 in our temporary household in Turkey suddenly failed to boot and got stuck on the grey screen. They were able to boot at the Apple store, but not when we brought them back to our apartment. Could this be a coincidence? A

THank you Ogelthorpe. When my wife's computer I went on line to the site that you sent and tried everything But nothing worked. When my son came to visit and his MacBook Pro did exactly the same thing we became suspicious - too much of a coincidence. We took both computers somewhere else, out of our apartment, and they both booted. We ran disk utility on both, but the report in both cases was that there are no issues with the hard drive. Back in our apartment neither will boot up. My MacBook Pro is a later model with a solid state drive and it seems to work fine here.. I tried an external drive and it works fine. We think that this has something to do with some kind of magnetic interference in our apartment to which the 2009 drives are susceptible. It is indeed a mystery!

When I try opening iPhoto on my iMac (OSX 10.9.2) it says I must first update the application; when I try doing so from the App store, it says there are no updates available. I have not renamed or moved iPhoto which was preinstalled. How to solve?

When I try opening iPhoto on my iMac (OSX 10.9.2) it says I must first download the update; when I try doing so from the App store, it says there are no updates available. Stuck in a classis Catch-22 - any ideas how I might solve the problem?

Thanks a lot for your swift response. And sorry if it was a bit too hectic to go through my detailed query (which I did because it was misunderstood when I asked previously). As I've mentioned above, I was informed that updating to 5.0.1 would '''require''' me to '''delete''' the current version and then install the new one. And doing so will involve losing all my bookmarks. I guess I should have been more specific and detailed there. By losing, I didn't mean losing them forever. I'm aware that they're secured in some place and deleting and installing the software doesn't harm its existence. What I meant that if I install the new version, I'd have to delete the old one. And after installing the new version, I'd have to transfer them (bookmarks) back from wherever they are. Get it? When it updated from 3.6.9 to 3.6.13, and from 3.6.13 to 3.6.18, I didn't need to follow that process. They were already present on their own.
BTW, I'm having no problems with 3.6.18 but after learning about the existence of version 5.0.1, I'm a bit too eager to lay my hands over it.
Thanks for your help; hope this wasn't extremely long.

Installing Windows 7 on my bootcamp partition (mid-2009 mac book pro with mountain lion) My computer won't boot from the Windows 7 Install DVD.

Hello,
I have been trying to install Windows 7 on my macbook pro (mid 2009, MBP53). I have successfully created a bootcamp partition using the assistant. When the computer tries to boot from the windows 7 install dvd, the screen is just black. The dvd spins for a bit, then stops and the computer is just black (no blinking cursor).
Any advice would be very appreciated.
Thanks.

What kind of an install DVD are you using for Windows?
You can use any DVDs that are hardware specific. Only the full non-hardware soecific DVDs work on the Mac.

When Lion officially comes out from the Mac App Store, I understand that I can just buy it from there. However, will the laptops have Lion automatically? Or does it come with Snow leopard still.

When Lion officially comes out from the Mac App Store, I understand that I can just buy it from there. However, will the laptops have Lion automatically? Or does it come with Snow leopard still.

The ones sold that day will come with Snow Leopard most likely but they will be able to get a free upgrade to LIon if they apply within 30 days. Hardware coming through the supply chain from the day of the announcement will have Lion installed so it depends what stock people have to move before buyers see those.

IMac won't boot from any HDD or install disc

Hi everybody.
This morning my iMac just didn't wanna boot up, it powers on and the start sound plays but nothing more, all white screen.
Tried holding OPT at start, my mouse cursor becomes visible and active but none of my startup drives show. Also tried booting from both SL and leopard install DVD, it reads the disc for a minute or two then spits it out, nothing on the screen, all white.
Tried resetting PRAM, holding down CMDOPT+PR, it reboots but same thing after that.
My internal HDD crashed recently so I've been booting from my external drive which has SL installed. This has worked fine unitl now, last night I shut the machine down it did take an extra two minutes to power off which was out of the ordinary.
All help appreciated which can avoid me from sending it in for repair.

Thanks for the reply.
Since my internal drive had been failing I guessed it had to be the culprit and right I was. After I swapped the HDD (plus swiped the interior clean) my iMac was like new again plus I didn't have to send it away.
But what I can't quite understand is why a bad internal drive which was not in use would hinder the mac from booting from the install DVD all of a sudden.

Imac freezes with gray screen after mavericks update

I was updating my imac system and it is frozen in a gray screen, like it is restarting.
It's been twenty minutes and it didn't restarted.
What can i do if it don't restart anymore?
All my work data is on that imac.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
     a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

27" iMac stuck in Grey screen after startup

Hi everyone, I've read nearly all the posts on this subject. According to all the tips and suggestions I've done a SCM restart, I've run applejack and done an sbin/fsck -y rebuild, I've attached it to my Macbook pro via firewire in T mode and run disk utilities, I've also tried to startup from an install disc and got nowhere and I've done a PRAM rebuild. Still nothing. Someone thought it might be a Kernal panic?? Oddly enough I think it's a video card problem. as I have a second 27" Monitor and when I plug it in I normally get both screens go blue and then a second or two later I get both screens showing their respective images. This time I got nothing. not even the blue screen. I'm going nuts here. Does anyone have any ideas what the problems is???? Please help. oh and contrary to my listing, I'm running 10.8.1, not 10.6.8 ( I must fix that)

I have a MacBook Pro late 2008 edition with 2 Gigs of RAM and running Mavericks. When trying to download Yosemite from the App Store it gives me an error message. Anyone has a similar problem?

MacBook Pro late 2008 edition with 2 Gigs of RAM and running Mavericks (10.9.5). It gives me an error message when I try to download Yosemite

All,
I thought it may be related to spaces in the path in which the script was called from. I tried having the ODBC command script in another directory but the same thing happens. It will give me the "CONFIGSYSDSN: Unable to create a data source for the 'Oracle in OraClient10g_home1' driver: Could not load the setup or translator library with error code -2147467259". As soon as the script is done running I can manually double click the script and it adds the DSN fine.
Thanks,

Time for the empty grey screen after power on

Hello all!
This is about a MacBook Core 2 Duo with a 160GB drive (7200rpm) and 2GB RAM.
I have the feeling that the time needed to start the MB has increased over month, eventhough it feels rather fast when MAC OSX is finally started. The biggest question mark is about the time the MB needs after I have switched it on till the *light grey* Apple is displayed. This takes about 30 seconds and I have the feeling that this time used to be way shorter.
How about your MBs out there? Is 30seconds a usual amount of time? Does anybody know what happens during that time and if there are any dependencies to the individual hardware config? On my MB this time remains the same and seems not to be influenced by any USB or FW devices.
Thx for your info on that!

Hi Thomas!
Are you getting a boot chime (POST)? Then sitting at a black screen? It's highly unlikely that it's taking 30 seconds to POST, but I figured I'd ask. You can try two things:
Reset PRAM- http://docs.info.apple.com/article.html?artnum=2238
Reset SMC- http://docs.info.apple.com/article.html?artnum=303319
This should resolve the issue, unless there's some potential directory damage on your HD. But it sounds like the delay is prior to the loading of the kernel, perhaps it's a power issue. Can you try to power it on without the battery in place?

After one week of using Garageband, a exact copy of the app appeared. I deleted the copy but the also original app was deleted. When I try to downloaded from the App Store again, it appeared that the app has already been accepted but I can´t find the app

It appears that it is in the purchases list, but it is not there, HELP

The reason, I included the annotation that I'd upgraded my Itunes, (On my Computer) is B/C in many forums - the very first question, *HELPERS* ask, is. "Do you have the latest version of Itunes downloaded on your computer." I wanted to knock out any obvious replies.
Now- "DO YOU have any idea,"... how your UNHELPFUL remarks, do absolutely nothing but hurt others that might not have the EXPERIENCE you have? How do you expect people to know things without asking questions? Whew! RUDE!!

Is there any estimate as to when firefox will be available for compatablility with Coby MID1126, currently when i try to download from the Android Market it says you don't have any devices (it is a wifi tablet connecting at a free wifi hotspot)

i tryed downloading the package and installing it off the usb port as a download and the file crashed

Except for the Telechips TCC88xx processor series, all of the others are not ARMv7 type of cpu's but say ARMv6 or ARMv5. http://www.telechips.com/eng/Product/Product.asp
It is more of a matter of whether the device has the appropriate hardware (and 512+ MB RAM) versus making mobile Firefox for specific devices, especially if they do not have a ARMv7 type of cpu.

Stuck at grey screen after reboot

I seem to be stuck at the grey screen after a reboot of my server. Here are the symptoms and I'm wondering if anyone has experienced them before or has some idea of where to look:
1) Over the last couple of weeks, I've noticed the entire system freezing up for 10-20 seconds. The spinning pinwheel pops up and when my office is really quite, it sounds like either a fan is starting on the system or a hard drive is spinning up. Note that I've turned off all 'spin drives down when possible' in energy savings.
2) After the 10-20 seconds, a bunch of disk activity occurs and everything goes back to normal.
I've tried repairing permissions, checking for errors with the drive, etc. I've got two drives striped in Raid 0 (yes, the system is backed up--so I'm not worried about loosing data).
After a recent software update, I had to reboot it, and that's where it got stuck. Could be something there for some time, but my server usually runs for months at a time, unless an update requires a reboot.
Thanks for any help or suggestions!

Could you be more specific about what disks you used to boot with and exactly what programs you ran...
I cannot seem to get it to boot from the "Admin Tools" disk using the "D" key.
Also, when booting from the "Mac OS X Server" disk I can access Disk Utility, but do not see Raid Utility anywhwere.

My iMac stayed with grey screen after power on. It repeatedly booting when I try to boot from the Mac OX install Disc.
