    Exclamation Can't install OS x Mavericks to my iMac 20-Inch "Core 2 Duo" 2.66 (Early 2008)
    I deleted the partition on my iMac then got a copy of mavericks OSX on my USB stick via TransMac, when I entered the restore menu on my iMac and selected the USB stick it booted then gave my a grey screen with a black stop sign( picture below). So I tried the online solutions via the disk utility and entered my Apple ID and Password but it would say "this item is temporarily unavailable" (Picture below) searched for solution and one was to try to log in to my iCloud via safari in the disk utility when I visited iCloud.com a pop up said " Connection error" (Picture below) before logging screen appears. This took me several hours but I feel powerless at this point and would be grateful if someone would help me out.



    PS. when trying to erase my HD I found "Mac OS Extended(Journaled)" not "Mac OS X Extended (journaled)"

    Also the OS that is available in the online installation(disk utilities) is OS Yosemite.

    A warm welcome to Mac-Forums. Sorry for the delay in getting back to you.

    From your description of events, I suspect that you may have gone the wrong way about acquiring Mavericks (10.9.x) especially from TransMac. And the installation process is corrupted in some way.

    According to everymac.com, your iMac should be able to handle up to El Capitan (10.11.x) and everymac is usually accurate in its detail: iMac 20-Inch "Core 2 Duo" 2.66 (Early 2008) Specs (Early 2008, MB324LL/A, iMac8,1, A1224, 2210): EveryMac.com

    That being so, and as Mavericks is no longer supported, Apple has allowed for a legitimate download of El Capitan from here: How to upgrade to OS X El Capitan - Apple Support

    I think that would be a better option for you. The support article takes you through the process.

    Transmac will not work on a Mac period.
    Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    Thank you for the help, Do you have any idea where to download El Capitan from where I can mount it to my USB stick, and what software do you recommend other than TransMac for windows 10.

    Yes. From the site I quoted: How to upgrade to OS X El Capitan - Apple Support

    You shouldn't download it to a USB Stick, really. If you want it, download and install it to your Mac or, if you must, to an External Hard Drive (EHD).

    As I see things - correct me please if I'm wrong - you have a 2018 iMac which is pretty useless as it stands; but can take El Capitan. I've given you the Apple site from which you can obtain it.

    As regards Windows 10, I apologise, but I don't use Windows. The usual way to run a Windows OS on a Mac is via Bootcamp or one of the Virtual software apps. That would be after you've got El Capitan. And I don't know whether EC supports the latest version of Windows.

    I'm delighted to assist, but I'm not sure what your final aim is.

    I really appreciate your help man really, actually I have an early 2008 iMac and I want to install any OS X on, but as Mavericks is outdated and cannot be installed I should install El Capitan, but my iMac isn't working because it has not OS X installed thus I can't install El Capitan the way you suggest I do, so I'm thinking to make a bootable USB stick to install the OS X using the recovery mode, and I currently only have windows that I can operate with, and another comment on this post said "Transmac will not work on a Mac period." so I'm really confused now. Can you please direct me with steps what exactly I have to do, I would really appreciate it. Thanks.

    Have you tried any of these? How to reinstall macOS from macOS Recovery - Apple Support I don't know if they will work with your old and now useless iMac but you can always try. The big mistake you made was erasing it before you had a proven installer. That is not to criticize your action, but as a warning to others who may read this thread when they want to upgrade an iMac.

    See if you can get an installer from this Apple Support Document, If an installer says it can'''t be verified or was signed with a certificate that has expired - Apple Support.

    Here’s another Apple Support document that my help, Use the Mac operating system that came with your Mac, or a compatible newer version - Apple Support
