Unable to install Lion

I have installed Lion on my macbook pro without issue but when I tried to install it on my (newer) iMac it keeps crashing after the install. I have tried 3 separate installations including a complete new download of the installer. Whenever I start up after the installation it gets as far as the toolbar and dock and then comes the black curtain and a message to manually restart the computer. No matter how many times I try it keeps doing the same thing and ultimately I have to restore from SL 10.6.8. I would like to use some fo the new features but if I can't get Lion installed I will have to give up altogether.
Any Ideas?

That type of thing should only be installed if Software Update prompts an install since they are machine specific.

Unable to install Lion - S.M.A.R.T. errors on my hard drive???

Unable to install Lion on a 27 inch 3.06 Intel Core 2 Duo iMac running OS 10.6.8. When I am presented with install options, my HD option is dimmed and there is a message: "This disk has S.M.A.R.T. errors. This disk has a hardware problem that can't be repaired. Back up as much of the data as possible and replace the disk."
I have not had ANY problems with this iMac since purchasing it and other than being unable to install Lion it seems to be working just fine, and yet now I'm told that my hard drive is unrepairable.
Is this a glitch in the Lion Installer or should I be more concerned?
Any info appreciated... now it seems I've paid $30 for a download I can't use. Grrrrrr....

Check it via Disk Utility (in your Applications/Utilities folder) on Snow Leopard:
If that says there's a problem, too, there's likely a problem.
Be sure your backups are up-to-date, and let Apple have a look at it: http://www.apple.com/retail/geniusbar/

Lost applications symbol and unable to install lion

lost applications symbol and unable to install lion. Do I have to go back to original installation of operating system. If I do will I have to reinstall all programs?

A couple of questions:
Are you really on 10.5.8 (as shown in your profile)? You need to be on 10.6.8 to install Lion.
What exactly does the "lost applications symbol" mean? You mean it disappeared from the dock? Or is your Applications folder gone? Open a Finder window and see if you can find the Applications folder.

Unable to install Lion on iMac 27" i7 (2010) - no recovery system

I tried to install Lion in my 27" iMac i7 (2010), but the install process cancels, because it's unable to create the recovery-system. The suggested URL for support (www.apple.com/de/support/no-recovery) doesn't exist. What now? And better ASAP!

I managed to install Lion after doing the following steps:
(1) Remove Boot Camp Partition - Boot Camp Assistant > Remove Windows Parition
(2) Repair Permission - Disk Utility > Repair Permission (for main HDD)

Found out what my problem is!
In creating the Recovery HD, the installer was trying to write a new boot.ini onto my Windows partition, but I have mine formatted in NTFS, so it couldn't write anything to it. I guess that's what Apple meant by me "tampering" with my Boot Camp installation. So I guess I just have to reformat the partition in FAT32 and I should be good to go.

So if you're having the same problem as I'm, you can try these steps to install Lion.

Unable to install Lion Recovery Update v1.0 on Mac OS 10.8.2

Hi to anyone who can help,
As the "Find My Mac" option is greyed out, I followed all the instructions on the support forums on how to get this feature, such as Verify/Repair Machintosh HD using Disk Ultilty from the Recovery partition.
Subsequently I tried to install Lion Recovery Update v1.0 from the Apple Support link below:
http://support.apple.com/kb/DL1464
However, while attempting to install, it says "This update can only be installed on OS 10.7". How do I get this fixed?
Some background info, my MacBook Pro 15" (early 2011) had a replacement Hard Disk Drive and Logic Board.
1. The replacement drive had 10.7.4 installed, and I used the recovery partition to restore to a Time Machine Backup (which was 10.8.2).
2. Do I need to "download" the Mountain Lion package in the app store again? I see it as an available to download instead of saying "Installed".

Exit Code 6 is a generic error that indicates that the installation was not successful.
Have a look at the following document: http://helpx.adobe.com/creative-suite/kb/errors-exit-code-6-exit.html
A quick look at the error log, indicates a permission issues. Are you logged in with an Administrator account and have sufficient privileges to install software?

Unable to install Lion. Installer says disk is used for Time Machine backups. But it's my Mac's HD.

On attempt to install Lion from CD, the installer says: "Mac OSX cannot be installed on "Macintosh HD". This disk is used for Time Machine backups."
I have an external drive that I've been using for Time Machine backups, but it stopped functioning recently and I have not replaced it.
Is there a workaround?
Thx in advance. Bryant

Unable to install Lion due to unable to unmount disk

Need urgent help here.
I want to reformat my hard disk due to some reasons, and I tried pressing on Command-C while it boots up. Then I got into the Mac OS X Utilites, and then click on Disk Utility to erase my hard disk. Inside I have 1 hard disk named as Hitachi with a partition named Macintosh. I tried to erase the Hitachi one, but it says it couldn't unmount disk.
So I made a call to Apple and they told me to do a secured erase on my Macintosh HD Partition. Did that, and tried to install Lion to it, but I got this error.
"Could not find installation information for this machine. Contact AppleCare".
Anyone could help on this problem?
Coz I would need to wait for another 12 hrs or so before I could call to Apple.
Please help!!

But spotlight find it isn't it?

Unable to install Lion OS on MacbookPro.

I accidentally erased my mac hardrive in the recovery menu as I was trying to install a fresh version of Lion OS on a Macbook Pro I bought second hand.
I tried to boot from the internet recovery option which gets me back into the recovery menu, however when selecting the option to do a fresh install I am running into a problem.
When I enter my itunes/apple ID to complete a fresh install of the Lion OS I am told I have not purchased Lion and therefore the installation cannot proceed. As I bought the computer second hand I hadn't purchased Lion OS however I thought I could solve this issue by purchasing Lion OS on the apple website (the purchase was linked to my itunesaccount and I received redemption codes etc) and I am still unable to proceed using my AppleID/itunes account. I keep getting the same error.
Any ideas?
I was going to try and download my purchase via the App store, however I can't use the Macbook Pro to do this (for obvious reasons) and my only other option is my 6 yr old Macbook which runs Tiger... And I am unable to access the app store from what I can see on itunes..
I am not sure if I should be ringing customer support or billing for this issue because it could be related to my itunes purchase?
Any help would be greatly appreciated

I am assuming you are trying to install the desk top software, if so, and you have the software on a disk, or saved on your computer you should not need the internet to install it.
Can you give us a little more info?

Unable to install Lion on new hard drive.

Hello,
My brothers laptop hard drive died so I am fixing it for him. I've replaced the hard drive, created a bootable USB Lion install by following http://osxdaily.com/2011/07/08/make-a-bootable-mac-os-x-10-7-lion-installer-from -a-usb-flash-drive/.
I plug in the USB, hold down option, select the USB drive, and I get the wheel spinning and apple logo. After two or so minutes it turns into:
Does anyone have any idea as to why I am getting this? I've tried changing which USB hub it uses, tried redoing the USB, used a different USB, verified the md5sum (145dc094527a8d5f5f601c7fa53d7577) all to no avail.

Most likely you have a non-functioning system. It could be because the flash drive was not partitioned and formatted properly before you created the system on it or a flaw in your cloning. Not knowing which specific model you have it could also be that the system you cloned is not able to boot the computer because the computer requires a different version of Lion.

Unable to load many web based games after installing lion

After installing Lion, I am unable to launch several online games (Pogo e.g.). What compatibility issues are being addressed?

I didn't think reinstalling was gonna do me any good except for getting rid of every single thing I have ever installed since getting this MBP. I'm thinking it has to be something that is on my computer causing this, especially since it only affects my ability to get to this one site and I only started seeing this problem yesterday.
So, I went ahead and disabled all my Chrome extensions and I don't have any Safari extensions at all. That didn't fix my issue.
I've been trying to run Sophos on here, thinking that maybe I've got a Trojan or some kind of malware, but it never seems to finish a full scan of my hard drive. That "Plugin" that I mentioned above has me very suspicious, except that whatever that is, it's been on my computer since basically when I first got it. Maybe it's malicious, or maybe it's just a poorly named piece of software. In any case, it got updated last night around 11pm, about the same time I noticed my problem. After trying everything I have, it's hard for me to overlook that as coincidence.
But, where do I go to gain more information about what that could be? I should mention that this MBP is basically my first Apple computer. I've been a PC guy (still am mostly) forever, but I finally dove in and got a Mac to start iOS development. So I'm sure there are ways to get more information than I am currently aware of.
Also, apologies if I posted this in the wrong forum.

Many years ago synced iCal with Microsoft program. Since installing Lion whenever I try to create an event in iCal it flashes up message "Unable to open Microsoft sync services Power PC applications no longer supported." How do I get rid of message?

Lion no longer supports PowerPC apps. If this is Microsoft Office 2008 (Entourage 2008) then you should disable the syncing services. (I don't have Office 2008 installed anymore so I don't know exactly what it's called anymore.) If you have Microsoft Office 2004 or earlier, then it can't be run on Lion at all since Lion removed Rosetta, which is what allowed a PPC app to run on an Intel based Mac.
Also, I believe Microsoft removed sync services from the current Outlook 2011 (which replaces Entourage) so even upgrading to a newer version of Microsoft Office will not get you back that calendar sync feature. Supposedly Microsoft is working on a new syncing system, but I wouldn't hold my breath.

I am unable to install OS Mountain Lion

I am unable to install OS Mountain Lion, when i try to install it says a recovery disk can not be created, visit apple.com/support/no-recovery, is there a way to fix where i can get Mountain Lion?

Here's the article: http://support.apple.com/kb/HT4649
(macjack, I found I don't have permission when I tried to read the appleseed article.)
Bottom line: as macjack suggests, it looks like you're trying to install on a RAID or non-standardly partitioned disk. The article suggests a lot of Mountain Lion would work this way, but not everything.

Unable to install "InstallESD.dmg" file from OS X Mounstain Lion?

Hi,
Unable to install "InstallESD.dmg" file from OS X Mounstain Lion, i've downloaded OS X Mavericks and installed on other machine. However, i took backup of "Show Package Contents" before installing.When i try to install ""InstallESD.dmg" file some other Mac machine. When i double click on it its open Packages folder instead of installer.
Please suggest me, how can i install OS X Mavericks for My Mac machines.
Thanks in Advance,
Suresh Balakrishnan.

Unfortunately with OS X Mavericks you can't use the InstallESD.dmg file as an installer. You have to use either DiskMaker X 3.0.4 or Mavericks Bootable Disk Creation Tool or do an Internet search for the Terminal command that can be used to create a bootable Mavericks installer on an external drive (e,g, USB thumb drive).
You will need the Install OS X Mavericks.app from the Mac App Store to use with all of the above solutions.
