Apple shares some crucial blame in this, though, so let me tell you what happened. It’s an old story of hubris and exaggerated belief in one’s own abilities. And that is the most unnerving thing about it. Tl dr – scroll to the end of the article for how-to instructions

In that case, you want to install High Sierra without APFS conversion. I tried using eficheck from an elevated terminal, but whatever I try, I seem to get errors back.If you want to install macOS High Sierra on your old iMac and encounter a problem during installation, it might be an issue with the APFS conversion of your HDD. I have tried again now and I am currently on in Safe Mode. I had tried an NVRAM restart last night but it didnt help.
If eficheck detects a problem with your EFI firmware it will display a message.Thanks very much for your help with this. RestartData protocol installed successfully.įs_read_stream:14080: got err 5 reading at pos 0 in obj-id 357 (blkcount 168, len 690998)įs_read_stream:14080: got err 5 reading at pos 10489856 in obj-id 783556 (blkcount 255, len 1044892)ĮRROR!!! Load prelinked kernel with status 0x8000000000000007Įrror loading kernel cache (0x7)Since you have High Sierra installed it would also be worth running Apple's eficheck utility from Terminal. It is almost as though Apple no longer support upgrading a system of this age which is on OS X Lion, if you have 2 form factor authentication on your Apple ID. I would ok it and it would display the 6 digit code, but I had nowhere to put it as the App Store just kept refusing my password. It kept saying I had put in the wrong password and immediately my phone would flash up with the 2 form factor ID auth message to say my apple ID was being used. I did try this, but the system was refusing to accept my Apple ID.

In answer to your comments re not installing the update via the App Store. Then today, I booted up from cold and straight away, I get the cycling between prohibitory folder and Apple logo. I re-formatted the drive yesterday from OS X Extended Journalised to APFS and then ran Internet Recovery again. I got a copy of macOS HighSierra, and made a USB Bootable drive from it, but even when I used that to install a fresh version of macOS High Sierra, still I am getting this prohibitory sign flashing back to the Apple logo and then going. Now that the system has built via recovery, I am finding if I attempt to boot holding cmd + r, after some time, I get a no entry style symbol.Ĭode: sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia -volume /Volumes/ MyVolumeMyVolume = the name of your USB drive.Hi there. I am visiting a site tomorrow which has a brand spanking new 2017 21.5 inch iMac - I could try and take a time machine backup of it and put that on to this 2011 model, but I am not sure if that will be a success. I have a problem! I am off of work no, so no usb sticks I can try and download the right os onto. It makes no difference if I allow or not. It asks me to sign in to Apple ID, but immediately tells me that my password is wrong when it is not, and I immediately get a 2 factor auth notification on my iPhone to allow a login from a new device.

If I visit the App Store, it tells me I can upgrade for free to High Sierra but when I click download, it tells me: This update requireas macOS version 10.8 or later.įair enough, I have found a link which will take me to that version on the App Store.

It installed Mac OS X Lion 10.7.5 (11G63). I do have other models around the school, but they are all running Windows so they will all have this old OSX installed on them.
I booted up and did an Internet Recovery install onto the new SSD. No point cloning the original hdd as it was factory fresh. The computer in question was a spare, box fresh and never used.
I recently started a thread on how best to convert an older iMac 21.5 inch from a 500gb HDD to an SSD.įollowing on from some great advice on these forums, I have successfully changed the drive, BUT, I have got an issue.
