Installed Lion on an iMac and when it booted up no user accounts

only account there is available is a guest account that requires a password that I dont have

I installed Lion on my iMac and got a similar issue. My one user account wouldn't work and when I booted from a 10.6 install disk to try and reset the local password, there were no accounts except the actual root user.

  • I am trying to install Lion on my imac and it says it can't make a recovery disk

    I am trying to install lion and receive a message saying it can't make a recovery disk.  I am using a 2.33 GHz Intel Core 2 Duo iMac.  I do have bootcamp on it, but was never able to install Windows.

    What happens when Lion installs is it creates a Lion Recovery Partition at the very bottom area of the drive, this is used to Command R boot into and perform Disk Utility Repairs and reinstall Lion from Apple's servers much like a 10.6 disk will.
    So when you ran the Lion installer, it couldn't create this small partiiton, either because the GUID partition table (the map of your paartitions on the drive) is borked or there is data all the way to the bottom of the drive or OS X thinks there is.
    You set up the bootcamp parittion, so run that and delete the Bootcamp partition as your not using it or Windows, once it's finished reboot and try installing Lion again.
    I should warn you, Lion will not run your Rosetta based software or hardware drivers for external hardware, you may have to purchase all new versions. Not only that, hardware drivers may not be available for 10.7 thus rendering your third party printers, scanners etc useless.
    Before you install Lion, you should consult this web page
    http://roaringapps.com/apps:table
    to see if your current programs will break and when to expect a new version (likely paid)
    Also you shoudl check your hardware and the makers site if there is a 10.7 compatible driver/software for them.
    And once you think your ready to go to Lion, get a blank external powered drive and a free/donationware copy of Carbon Copy Cloner to clone your present (non-Filevault) 10.6 boot drive to the external drive.
    Later if 10.7 doesn't work for you, simply hold the option key and boot off the 10.6 clone, use Disk Utility to Erase the entire drive (the whole drive!) and reverse clone 10.6 back onto the internal drive.

  • Why since installed Lion on my IMac it happened many times that my computer freeze and I have to restart everything before something work again?

    Why since installed Lion on my IMac it happened many times that my computer freeze and I have to restart everything before something work again?

    To get rid of "pop-up ads and other crap on my computer when I am on the internet", click on Safari in the Menu bar, and select Preferences. Next select Extensions. Delete all of them. Restart Safari.
    The first step in addressing the black screen is an SMC reset.
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer. 
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

  • I recently upgraded to Lion on an iMac and I am trying to run Garageband but get message telling me that the instrument library is invalid and I should choose a valid Instrument Folder or re-install Garageband. Where do I find such a folder?

    I recently upgraded to Lion on an iMac and I am trying to run Garageband but get message telling me that the instrument library is invalid and I should choose a valid Instrument Folder or re-install Garageband. Where do I find such a folder?

    Thanks very much. Yes, I am using the installer files and serial number from the URL you referenced above. I have spent many hours trying to get it to work. I would love some help!!
    The problem is that the instructions that come in the pdf with the downloaded files do not work, because the files that download from that page do not have the names referred to in the pdf, and most of the things that are referred to in the instructions do not happen. Here is what actually happened.
    When I downloaded the files from the website, these are the files that downloaded:
    I double-clicked each one and they extracted into two different folders.
    Then I read a message on the forum that said to move all the extractred files into the same folder, so I moved all files into one file at C:\Creative Suite CS2\Adobe Creative Suite 2.0 as was pictured in the forum message. Here are screen shots showing all of the files in that folder I have now:
    So then I double clicked the "Setup" file and I got this error message:
    So then I tried to install the programs separately from the installer inside the folders Photoshop and Illustrator. I got this far and entered the serial number from the website:
    But then I got this error message, even though I was using the files and serial number exactly from the website:
    I tried both photoshop and illustrator and the same thing happened.
    (I also looked at Solution 2 that you mentioned above but I don't have anything called VCOM on the computer. Also the error message that I got is not that one.)
    I think I really need a set of instructions that lists the steps in order to do, but based on the files that actually download from the website and what happens when you extract the files. I feel as if I have all of the proper files but it still doesn't work.
    Thank you very much!

  • I replaced my 2010-2011 iMac internal HD i dont have an install disk i created one with my external HD but when i go to install lion onto my imac it stays at the apple logo screen.HELP ME PLEASE!

    I replaced my 2010-2011 iMac internal HD i dont have an install disk i created one with my external HD but when i go to install lion onto my imac it stays at the apple logo screen.HELP ME PLEASE!

    Boot from the original Install disc that came with the computer and then format the drive Mac OS Extended (Journaled) using the GUID partition. Then  you can re-install OS X. If you no longer have the original media call AppleCare with the serial number of the machine (look on the bottom of the stand) and for a nominal fee they will ship you replacement media.
    The chances are very good you will have fan problems if you used an off-the-shelf HD, beginning in 2009 Apple began using HD's from vendors that incorporated heat sensors into the HD. If you did not buy the same type of HD your computer will think the HD is overheating causing the fans to run at full speed.

  • I downloaded and installed Lion on an external hard drive using my laptop which is running Snow Leopard I have now decided that I want to install Lion on my Laptop, but when I go to the App store and click on my purchases it will not download

    I downloaded and installed Lion on an external hard drive using my laptop which is running Snow Leopard I have now decided that I want to install Lion on my Laptop, but when I go to the App store and click on my purchases it will not download again

    Thanks Dirk,
                         Tried your suggestion various ways but it had no effect the download button was still greyed out and the install button would not activate will keep trying to find a solution. I dont want to boot from the external hard drive that has Lion on mainly because it is a usb HD and the connection to my wireless modem slows the connection rate and downloading would take about ten hours

    I purchased and installed Lion on my iMac. How do I install it on my MacBook without paying for it again?

    You'll have to download again.  You will not be charged if you use the same Apple ID.
    Save the file somewhere before installing.

  • Can I un-install Yosemite from my iMac and re-install Mountain Lion?

    Can I un-install Yosemite from my iMac and re-install Mountain Lion?

    Sorry to barge in like this but is it because you found it to have it's own way of doing stuff without your control? As i was thinking of doing the same thing because i found Mountain Lion much more user friendly.I know you came for an answer just was searching and came accross your question.
    Hope you find the answer. good luck.

  • TS3276 After installing Lion in my iMac, some formatted emails contain in sections of the text rows of letter A contained in boxes.

    After installing Lion in my iMac, some formatted emails contain, in some sections of the text, rows of the letter A contained in boxes. See attachment.

    In general theory, one now has the Edit button for their posts, until someone/anyone Replies to it. I've had Edit available for weeks, as opposed to the old forum's ~ 30 mins.
    That, however, is in theory. I've posted, and immediately seen something that needed editing, only to find NO Replies, yet the Edit button is no longer available, only seconds later. Still, in that same thread, I'd have the Edit button from older posts, to which there had also been no Replies even after several days/weeks. Found one that had to be over a month old, and Edit was still there.
    Do not know the why/how of this behavior. At first, I thought that maybe there WAS a Reply, that "ate" my Edit button, but had not Refreshed on my screen. Refresh still showed no Replies, just no Edit either. In those cases, I just Reply and mention the [Edit].
    Also, it seems that the buttons get very scrambled at times, and Refresh does not always clear that up. I end up clicking where I "think" the right button should be and hope for the best. Seems that when the buttons do bunch up they can appear at random around the page, often three atop one another, and maybe one way the heck out in left-field.
    While I'm on a role, it would be nice to be able to switch between Flattened and Threaded Views on the fly. Each has a use, and having to go to Options and then come back down to the thread is a very slow process. Jive is probably incapable of this, but I can dream.
