Brand new iMac 27 2011 won't boot after Lion upgrade

Got a brand new iMac 27 2011 yesterday and did an update to 10.6.8 first before installing OSX Lion over it...
After restarting it just shows then the "prohibitive icon" on screen and shuts down after few seconds...
It won't even boot from an USB stick with the OSX Lion image on it...
Recovery partition works but can't do a reinstall from there....
So going back to 10.6.8 now...

Just so you know I purchased brand new imac in July and did the same upgrade as you. I just installed Lion but did not have any issues. Only one concern overall though, it slowed down my new imac a bit. Not sure if there are settings or not but Leopard was faster than this. AppStore, iTunes are eating lot of memory and CPU util goes up.

IMac 8,1 won't boot after Lion Install.

Hey guys,
I have an iMac8,1 with a 2.4GHz Intel Core 2 Duo that I just installed Lion on.
It previously had Leopard on it, but after shutting it down to boot from the USB stick that I had made on my MacBook, I pressed alt to show the device selection menu. There were no options except EFI boot with an orange drive, which I took for the Lion stick that I had made. Installing Lion went without a hitch. I formatted the drive that Leopard was on and did a clean install. After it was finished, I set up Lion and set up a Boot Camp partition so that I could install Windows 7 side by side with it. I booted into the device selection menu (holding down alt/option while booting) and it showed me a completely blank screen. No Macintosh HD, no EFI boot, no Windows DVD, nothing.
I put the flash drive back into the machine, and kept restarting it and seeing the same result, until all of a sudden it decided to finally start, and I saw the Apple logo. After a while, though, it became apparent that it was not booting into OS X Lion on the hard drive, but rather the Lion Install.
I have no idea what to do with this machine. It was running extremely slowly before I started trying to fix it, and it didn't make sense to me that a machine with fairly capable specs (I have the same processor and 2GB of RAM on my MacBook and it runs great) would run so catastrophically slowly.
Also, I'm now in Disk Utility running from the Lion USB and it a) sees both partitions and mounts them fine, b) says that "The volume "Macintosh HD" appears to be OK", after Repair Disk c) is unable to fix or verify disk permissions.
I'm at a loss as to what to do. Can anyone help?

If you have backups of all OS X and WIndows data on the internal drive, I suggest you partition it with the default options (GUID partition table, one data partition) while booted from the USB device. Install OS X and test. If you can boot in that configuration, restore your OS X data and then run Boot Camp Assistant, if you wish.
If the above procedure is unsuccessful, the machine has a hardware fault.

Mac mini won't boot after RAM upgrade.

Tried installing new RAM in my Mac Mini, 512MB stock to 2GB of Crucial. Followed the directions to a T, grounded myself the whole time.
Things I've tried so far:
1. Resetting the PRAM, no luck.
2. Holding option at start-up, shows no icon.
3. Holding shift, no luck.
4. Holding X, nothing.
How do I get it to accept a CD if it won't boot?

Welcome to Apple Discussions!
You clearly have a problem, but you don't describe exactly what that is other than that your mini won't boot after the upgrade. What happens when it starts up? Does it attempt to start and hang up on the grey or blue screens, or does it start beeping at you almost immediately after you try and start it up, and also flash the power light?
If the former, then you may have dislodged a connector while working inside the system, in which case opening it up and checking that everything is firmly connected would be the first thing to do. If the latter, then the beeping/light flashing is the system telling you it has failed the power-on self test and the pattern of beeps/lights indicates why. In your case likely the system can't find workable memory. In that instance, opening the system and ensuring that the RAM is firmly and fully seated would be a good step, and if the mini continues to fail, then replacing the new RAM with the original to test that the system will then start.
It is not likely that anything had damaged your MacOS install in the process of upgrading, thus normally no reason to need to boot to CD as a result of a RAM issue.

Brand new iMac 21.5" won't turn on - straight out the box

I just picked up my new iMac today and unpacked it etc, but it won't turn on. The wireless keyboard and mouse are supposed to be paired with it and ready to go, but the on switch on the keyboard won't turn the screen on (as far as I can tell there is no on switch on the iMac itself). The green light on the keyboard keeps blinking but doesn't connect to the iMac to turn it on. I've tried a different power cable in the iMac but that makes no difference. Does anyone know of a solution, or will it have to go back to the shop ( ) ?

The power switch is locate in the back on the lower left side as you look from the front. Did you connect the power cord and plug in the computer? There is no power button on the keyboard.

Brand new imac G5 17" won't start up

Hello,
I just received my new imac today and was really disappointed when after I'd hooked everything up and when I hit the power button the screen stayed black and a small white light on the front turned on for just a second.
Any ideas??? I tried the online chat support--no help there... and, of course, there's no phone support right now. I'm really frustrated. Any ideas would be greatly appreciated. I have a bad feeling it just doesn't work.

I feel your pain. I received a brand new 20" a few weeks ago with the same symptoms. Spent time on the phone with tech support and brought to local Apple Store only to hear them say the unit was DOA. The local Apple Store had not yet received the new 20" models so I had to send the unit back to Apple. I'm a first time Mac owner, and needless to say this was not the first experience I was looking for. I'm glad to say that my second one is running like a charm. You should be able to exchange yours for a new one at a local Apple Store, if you did not make any customizations on your order. Good luck.

Brand New MacBook Pro 15" Won't Boot from CD only

This Macbook (which I just bought today) seems to refuse to boot CDs.
- Booting from the normal hard drive works fine.
- Loading the CD from the OS when booting from the hard drive works fine (I can interact with the CDs normally)
- Same problem with Apple OS disk & self-burned TechTool Pro disk
I've tried resetting the PRAM three times now. Any idea what's wrong?

Hmm, I hadn't tried booting the system restore CDs that came with it. Turns out they work just fine. The two CDs I was trying to boot (but aren't working) are:
- Micromat TechTool Pro 5.0.4 (self-burned on a Gigaware DVD-R)
- Mac OS X Snow Leopard OEM (bought independent of this machine when Snow Leopard was first released)
I've since tried resetting the SMC by another Apple Support article (http://support.apple.com/kb/HT3964) to see if that helps. My TechTool DVD still won't boot, and I haven't tried the Snow Leopard disc yet, but the CDs that came with the MacBook work fine.
It's also interesting in "how" it "doesn't work".
(By CD in the following points, I mean the TechTool CD):
1. I insert the CD when the system is running normally. I can install TT, and browse the contents of the CD without issue.
2. I restart the machine, holding down the Option key. Both my HD and the TT CD appear as bootable options. I select the CD.
3. I get the grey Apple, but the "spinning wheel" never appears. After a few minutes, all noise from the super drive dies, and the system sits there interminably.
Both the burned TT and Snow Leopard CDs boot just fine on my girlfriends older 13" white MacBook. Any reason why mine would boot some CDs and not others, when the others boot fine on other systems?

IMac won't boot after ram upgrade

For some reason, my iMac late 2013 3.4Ghz quad core i5 won't boot with new ram modules added. New ram is exact same specs as original that came with the iMac. I've tested the new ones on their own in the iMac, and the system boots up fine. Same goes with just using the original ram. But when I put all 4 together, the iMac doesn't boot up. Not even the chime.
Combinations I've tried are:

I just got off the phone with Apple, and they are saying all modules have to be the same size. ie. all 4GB or all 8GB. Can't mix and match sizes. Which is strange, because I've never heard of this. My Mac Pro has different speed ram modules, with different sizes in it. As long as I install ram in pairs, it runs like a charm. I've even heard the new iMacs don't have to have ram installed in pairs.
I'm wondering if slot 2 and 4 are maybe damaged? I haven't tried using just slot 2 and 4. To my understanding, you have to use 1 and 3 first. Can anyone confirm this?
Also, I've read a couple of people had to wait 30 seconds for the chime when they installed new ram in their iMacs. I didn't wait 30 sec to see if it would boot. Never heard of any Mac taking 30 sec to just chime in. lol Has anyone else experienced this? Is there a fix? Tx.

IMac won't boot after Lion install

I have an Intel iMac circa 2007/2008. I just installed OSX Lion on it. After installation, the computer would beachball frequently and eventually froze completely. I had to do a hard-reset as the system was completely unresponsive.
Now the computer won't boot up. It gets stuck at the grey screen with an Apple and a spinner at the bottom.
Please help; this computer runs my small business.

How much RAM is installed? Lion will run much better with at least 4 GBs of installed RAM.
I would guess you updated from Snow Leopard and that Snow Leopard was not in good shape. Reinstall Lion to see if this fixes things for you:
Reinstalling Lion
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alterhatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

AP350 won't boot after IOS upgrade

I have an AP350 and after I upgraded the IOS to 12.2.15-JA it won't boot. In monitor mode it tells me there are no bootable images available. I see the new image there. I was having issues with the authentication on this box. This was the reason to upgrade the box to begin with. Now I have more problems here. If anyone can help please I could use it. The old directory where 12.2.13-JA1 was in is not there and the new image is not in a directory either if that helps.

Please read the attachment. It shows you how to recover IOS from bootstrap. Specifically, please go to "Using the MODE button" in "Reloading the Access Point Image"
As a side note, you cannot use HTTP interface to upgrade IOS software starting 12.2(15)JA. Below is from release notes:
TFTP Required to Upgrade 1200 Series Access Points to this Release
Software upgrades fail when you use the web-browser interface to install Cisco IOS Release 12.2(15)JA on 1200 series access points. The image size exceeds the access point's 4-MB restriction for software upgrades. Use TFTP to upgrade your 1200 series access point to this release. For complete instructions on using TFTP to upgrade access point software, see the "Working with Software Images" section on page 20-18 in the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points.

Early 2008 MacBook Pro won't boot after Lion 10.7.1 update

My 2.4 GHz 4GB RAM Early 2008 MacBook Pro wont boot after downloaded the Lion 10.7.1 upate. Upon restarting the screen went dead and now the system does not boot, as if the bootloader has been wiped out. Screen appears dead but was known to be working before hand. The hard drive spins up but doesn't sound like it is searching for data.
Can anyone help me?

Okay, I tried everything I can think of last night. I removed every startup process and every tool or programm that goes deeper into the system (GlimmerBlocker, LittleSnitch, Parallels). Cleaned Up every Cache I could find and refreshed every necessary Cache or Database possible. Took me a couple of hours. But still no luck - the machine doesn't boot, just in safe mode. Right now I copy all my personal stuff to a new external harddrive because TimeMachine doesn't work, after this I will do a clean install of Lion.
It's not hardware related, it's the 10.7.1 update that doesn't work properly. By the way, the only errors remaining are:
WindowServer - kCGErrorFailure
ManagedClient - kCGErrorFailure: CGSPackageGetWorkspaceType: couldn't get workspace type
SecurityAgent - kCGErrorFailure: CGSPackageGetWorkspaceType: couldn't get workspace type
and a lot of:
com.Apple.SecurityAgent.00000000-0000-0000-0000-0000000186A7: CoreAnimation: rendering error 506
that's also the last one I get before the system hangs…

Won't boot after kernel upgrade

I installed Arch and attempted to upgrade the kernel. I had to remove these pkgs because the depended on previous kernel:

Dropping to recovery shell...
This is the final error messages after making the following attempts to correct the problem:

Added rootdelay=8 (then 20) t6o kernel line.
Replaced UUID moniker with /dev/sda1 (SATA drive).
Checked /dev/ in recovery shell, no HD's listed.
Checked /etc/mkinitcpio.conf and it has sata listed under HOOKS.

Satellite A200 PSAEOE won't boot after memory upgrade

Hi, I am first time here.
I have bought a Toshiba A200 PSAE0E-03J02JDR with 2 GB ram memory. I bought a pair of Corsair ram (2*2GB VS2GSDS667D2). After I installed the memory the computer won't boot. I have intel 945 chipset, which is capable of 4 gb (manual page1-2). The bios version is 1.8 from 2007.
Can anyone help me, please.
Message was edited by: ovidiu marian

Hi
The A200 series supports different chipsets;
Intel 945PM
Intel 945GM
Intel 943GML
As far as I know your notebook supports the *Intel 943GML* chipset and this chipset supports max 2GB RAM.
Take a look in your notebooks user manual *Page 18.*
Summery: 4GB RAM are not possible and therefore your notebook does not boot up.

GE60 2OC won't boot after RAM upgrade...

Hi forum
I just upgraded my laptop ge60 2oc 014ne, with two 8 GB corsair value select sticks.
Now my machine won't boot. I hit the button, the power light turns on, then the harddrive indicator lights for a while... And then it just stands there... Nothing shows on the screen..
Any help? Please..
Cheers

another thing is that you can't put in more RAM than the notebook came shipped with right?
If it originally had 8GB over 2 slots you can't put in more than 8GB in the entire notebook right? (I thought I read something about that somewhere....)
Nope. Not true.
In most cases it's restricted by 1 of 3 things....either the CPU, the IMC (Integrated Memory Controller) or the BIOS.
MSI is pretty good about NOT restricting it via the BIOS in some way.
Usually it ends up being the IMC that restricts it, either via a maximum memory (say 32 GB) or via a maximum amount of memory per module (say 8GB).
Either way, the GE60 I believe should support up to 16GB of memory. I think it should come with 2 memory sockets. You need to ensure that they are 1.35V compatible given the fact that you have a Haswell system.
http://www.msi.com/product/nb/GE60-2OC.html#specification
Confirms that it has 2 memory sockets, and supports up to 16 GB of memory, so 2 x 8GB sticks.
