Late 2011 Imac SL DVD Boot

I have a late December 2011 iMac. I wanted to help a friend troubleshoot a problem he was having getting his Older G5 to start from an install disk.
He is in antoher state. I decided to take my retail Snow Leopard install disk and pop it into my Imac just to go through the motions of booting up from the install disk. I wanted simply to access disk utility in this case. His issue was a question ? on his screen and I wanted him to access this untility. Well I wasn't able to boot from the disk. In fact, It actually crashed the iMac with a Kernal panic on the third try. I put the disk in an earlier MBP Pro and it booted just fine. Both machines are running Lion 10.7.2. Am I to assume the new iMac will not allow a boot from an Snow Leopard DVD?

Most likely the version on the Snow Leopard DVD is not late enough to boot the iMac. It would take 10.6.4 or later depending on which iMac model. The latest ones need a build of 10.6.6.

My 2011 IMac will not boot up past the White apple logo screen with the whirly circle

My 2011 IMac will not boot up past the White apple logo screen with the whirly circle. I have tried various commands but to no avail. does anybody have any advice?

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.

Late 2011 iMac Causes USBs to be Write Protected and Cannot Reformat?

Hi all,
I have been having an issue with my Late 2011 iMac - every once and a while upon insertion of the USB, nothing can be transferred onto the USB, however existing data on the USB can be transferred off. For the first several times, the Mac will allow me to erase and reformat the USB - however after ~4 - 5 reformats, the USB will no longer allow me to reformat it - either through a Mac or a PC. Recently, the same problem also happened to my Micro SD card and I'm getting pretty stumped.
Currently running 10.8.2 - however problem also occured using 10.7.
I do use a Belkin 4 USB port extender connected to my Mac via an old USB 1.0 cable.
Can provide screenshots, any help is much appreciated
Thanks
Aaron

What -rc & -d do.
From: The fsck_hfs manual page.
https://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages /man8/fsck_hfs.8.html
-d      Display debugging information. This option may provide useful information when fsck_hfs cannot repair a damaged file system.
-r      Rebuild the catalog btree. This is synonymous with -Rc.
-R flags Rebuilds the requested btree. The following flags are supported:
                         a       Attribute btree
                         c       Catalog btree
                         e       Extents overflow btree
I had the same problem as you but unfortunately "fsck_hfs -rc -d /dev/disk0s2" is failing saying: "The volume   could not be verified completely." I believe it's supposed to be telling me the partition's name (normally "Macintosh HD") between 'volume' and 'could' because there's 3 spaces in between the words.
"fsck_hfs -fy /dev/disk0s2" is failing with the same error.
I tried "fsck_hfs -r -d /dev/disk0s2" since the c appears redundant with a lowercase R. and it again says it cannot be verified completely and adds "volume check failed with error 7". Which unfortunately is not documented on the fsck_hfs man page!
Unfortunately for me, Diskwarrior still can't see my busted Mac OS partition.

How do I use my late 2011 iMac ( with thunderbolt) as external monitor for laptop/Xbox or other device with hdmi as output.

May be this question has been asked thousand times. how do I use my mid 2011 iMac ( with thunderbolt) as external monitor for laptop/Xbox or other device with hdmi as output. if apple hasn't removed that feature and has just moved that functinoality to thunderbolt then how can I use it. currently there is no laptop available with thunderbolt output. no 3rd party converter available. whats the use of having feature on latest functionality if we cant use it. I wish they would have made one port has mini-dvi and other thunderbolt for backward compatibility untill some vendor comes up with converter.

It Says :
Mac (21.5-inch, Mid 2011) and iMac (27-inch, Mid 2011) and later computers support Target Display Mode via Thunderbolt to Thunderbolt cable (2 m) when the source is another Thunderbolt-equipped computer.
Name one computer model/vendor which has thunderbolt as output for display + audio. this is so stupid to move to new technology without availbility of its compatible devices.

Mid-2011 iMac won't boot Win 8.1 (BC) w/ ACD 30 attached

I have a 27" mid-2011 iMac Core i7 with two external displays, an ACD 30" and a 20" HP. I spent a great deal of time watching Win 8.1 in a reboot loop after install (Apple Drivers installed fine), sometimes with vertical lines down the ACD 30 (nothing on the HP). (I didnt expect Win to notice the more than one DisplayPort screen.) Finally I disconnected the displays and I booted into 8.1 fine.
IS this a thing? Others share this experience?
Thats not the end of my Boot Camp woes, but that's all tied to this issue.
BP

Can you provide details on how each these displays are connected?
From iMac (27-inch, Mid 2011) - Technical Specifications, you have two TB ports, which can support DP connections.

Air Drop not in Sidebar (late 2011 iMac)

I have an iMac later 2011. When I originally used it Air Drop was on the Sidebar. However, I have not seen it in the recent updates. Now I have a MBP with Air Drop and really need to use it.
Howe can I get Air Drop back on the iMac?

This should have been in Mountain Lion, as both computers have ML. I reposted there. If necessary, can someone delete this post?

27" (Late 2012) iMac won't boot from any external drives.

I just got my 27" iMac (late 2012) with Fusion Drive. I can't get it to boot off any my external LaCie drive. I just get an "Ø" symbol. tried this so far:
Ensured the OS on my external drive is 10.8.2 - didn't help.
Updated (reinstalled) Mountain Lion on the external drive, using the Recovery HD that comes with the iMac, just in case it's a "special verision". - didn't help.
Connected via Thunderbolt-to-FireWire 800 adaptor - didn't help.
Connected via USB2 port on HDD to USB3 port on iMac - didn't help.
Used "Startup Disk" system prefs - didn't help.
Used "hold doen ALT key" after startup chime. Can see the drive but - didn't help.
So - has anyone had any luck booting a new iMac off an external device at all?
I might try a Carbon Copy Clone of the Fusion Drive - but I'm thinking it's a waste of time - instinct tells me it's a Firmware limitationin the machine that prevents booting from externals.

trying a clone after all due to this discussion https://discussions.apple.com/message/20938457#20938457

Mid 2011 iMac won't boot in any mode.

Hello,
Last ast week in the middle of a deadline my imac crashed. I was in the middle of a Pro Tools session and the next thing my mouse icon turns into a series of dots and everything freezes. So, I rebooted and since then I haven't been able to get it to boot in any mode.
On booting it gets to about 1/3 through the progress bar and then hangs.
I have tried the following, all steps have not worked:
Safe Mode
Recovery
Internet Recovery
External Mavericks Drive Boot
Resetting NVRam, PRam
I was able to use target disc mode to get my work from my drives. Randomly it booted once after the crash, I was able to run disc utility's repair disc on my system disc, to which it came back with "disc appears to be fine".
I have taken the iMac to my local authorised service centre, but so far it has been a week and they haven't even looked at it yet.
my question is basically, what could it be that is causing my iMac to do this? I was thinking it may be hardware issues.. But I have no clue really?

*Also,
I have tried running hardware test on startup, but nothing happens when I do. Just stays on the gray screen. After it randomly booted and I ran disc utility, it did the same thing. Mouse icon turned into a series of dots in a vertical line, froze, then rebooted.
After resetting the P and NVRam booting in safe mode shows a blue screen with vertical lines and/or shows some debug info on the gray startup screen.
I will post some photos for reference.

InDesign crashing in CS5.5 on OS 10.8 and 10.7, mid 2012 macbook and late 2011 imac

@indesign on twitter recommended i paste my crash report here. Enjoy! pastebin.com/W62vhw9S

Sorry, it crashes on opening the doc. Sometimes i get as far as scrolling down a couple of pages. Also, i'm not sure what an in place upgrade of OS is, but both machines are factory OS + only standard software updates. I didn't migrate the CS applications; the suite was installed on both machines directly from the discs. I am now far enough into a new doc started from scratch Monday night that I won't try to salvage the old one, but in case this happens to the new doc later this week (knock on wood), i am still curious if it's possible to isolate the corrupt element. Does the crash report say? I don't know how to read it... Once I had a corrupt file and was able to salvage it by re-saving it in a different location, but that hasn't worked this time.

Late 2011 Macbook Pro Wont Boot into AHT

My brand new MacBook Pro use to boot into the Apple Hardware Test.
Recently I was having software problems so I restored my mac from the lion restore partition, now I can’t boot into the Apple Hardware Test. I don’t have restore disks or software disks because my MacBook Pro did not come with them Any Ideas?
Thanks Kyler

First off, some other forum members have reported having to hold down Command-D instead of just D to get the AHT to load.
If that don't fix it, as per this article ( http://docs.info.apple.com/article.html?path=Mac/10.7/en/mh35727.html ) it can be loaded from a USB disk. Since your Mac came with a factory-installed Recovery partition, you can concoct a bootable USB startup disk (hopefully containing the AHT) as per these instructions: http://support.apple.com/kb/DL1433
Hope this gets you the AHT back.

Can a Macbook Pro 13" (late 2011 model) burn DVD's??

Simplistic question I realise. But I just need a quick answer (on behalf of my mum!...)
If not, what's the best way of going about getting app/s or an external 'plug-in' burner (preferably blu ray), to achieve this?
Also, do the models after this date have this ability or not, I heard 'not'?
Thanks, Stolky

It has a built-in optical drive, so it can burn DVDs using Disk Utility or the Finder or iTunes.
Starting with the 15" Mid-2012 Retina models you need to use an external optical drive.

27 ", late 2010, iMac won't boot after turning on. Spinning beach ball and white screen.

Probably a relatively simple fix, or series of steps, that will return it to normal.

BD,
It's been a while, but I have since upgraded RAM to 12Gb and gone to Mavericks 10.9.4. Everything has run well until recently. Time Machine will not function on a new Seagate, 1TB GoFlex external HD,even though it was properly formatted and HFS journaled. Seagate techs said it seems to be a failing drive, yet it works perfectly on my laptop, a 15" MacBook Pro with Mountain Lion. The drive completes less than 10% of the backup before it locks everything up on the iMac with the spinning beach ball and a gray screen. Left it that way for two days and no change. Removed the drive physically and the iMac works just fine. I am baffled and really a bit frustrated here and wonder if you, or anyone else, has an idea about correcting this? I am suspecting that there is something deeper in the system going on than I am seeing.
I have run a verification of Disc Permissions/Repairs and keep getting this coming up: "Permissions differ on “Applications/Safari.app/Contents/Resources/Safari.help/Contents/Resources/inde x.html”; should be lrwxr-xr-x ; they are -rwxr-xr-x ."
That keeps coming up every time and is not fixed. I don't know if that has anything to do with that.
Baffled...

My late 2009 iMac 27" will not boot completely

My late 2009 iMac will not boot-up completely. I get the little clock/second hand thingy on a white background, but no matter how long I let my machine try to boot, it still will not boot. Is there a "Safe" mode to possibly to boot into to get my iMac straightened out? Any other thoughts to try?

I can't boot windows in my iMac late 2011 as my internal cd reader does not work

i can't boot windows in my iMac late 2011 as my internal cd reader does not work

Which copy or version of Windows? and how where was it purchased?
my window installed itself perfectly on another computer.
One copy and you want to activate on two computers?
With 16GB, it will try to create 16GB hibernation file, 24GB page file, and need 20-30GB for the OS, plus room for temp, cache, applications, 9GB just temp to install SP1 update(s).
did you create 80GB or larger partition?
also, some macs with ssd + hard drive have issues, and of course you need Windows 7 64-bit home premium (Pro to use more).
OWC has up to 32GB, not cheap.
