Apple Intelligence is now available on iPhone, iPad, and Mac!
I have tried to update/upgrade from Yosemite to El Capitan with no good result. The computer will not accept to do the update and I´m afraid the Yosemite is already gone and I´m left with no option to return to Yosemite. Any solution to this huge problem would be appreciated?
What do you mean by "the Yosemite is already gone", do you mean you have erased your mac, if so that was
the wrong thing to do.
If you have not erased your mac you can easily upgrade to Mac OS X El Capitan by following these instructions.
If you do have an operating system on your mac and it is functioning then you can download
El Capitan using this method.
Open your Safari browser and click on the link below,
https://support.apple.com/en-us/HT211683
Go to Use Safari to download….. and click on OS X El Capitan 10.11
this downloads InstallMacOSX.dmg to your Downloads folder.
The next section can only be done on a mac that is capable of running El Capitan.
This includes macs that have the potential to run El Capitan but have been upgraded to a newer OS.
A mac that came preinstalled with an OS later than El Capitan will refuse to do the next bit.
When downloaded open to InstallMacOSX.pkg, double-click on
that and an installation window will open, this does not install El Capitan
but converts the InstallMacOSX.pkg to the Install OS X El Capitan.app which
you will find in your Applications folder, it should be 6.2GBs in size.
(If the installation window asks which disk you want to install to, you must pick
the disk that you are booted to at the time. Not any internal or external disk that
you want to eventually install El Capitan on, that is for later.)
To start the installation of El Capitan double click on the Install OS X El Capitan.app.
The copy of the install app self deletes after installing El Capitan, so make sure you keep a copy of the
InstallMacOSX.dmg if you need it in future, or you could just make a copy of the Install OS X El Capitan.app
prior to installing and moving it to an external drive for safe keeping.
It is also possible to create a bootable USB installer disk using the Install OS X El Capitan.app in the Applications
folder and the createinstallmedia command in the Terminal app.

You haven't really explained how you tried to install El Capitan.
Were you trying to install El Capitan through Apples Recovery Servers.
If you cannot boot the mac up to Yosemite we might have to assume you erased the Disk
losing all your data, if so see below.
Use the Snow Leopard DVD.
Insert the DVD and Restart your mac while pressing and holding down the C key.
When the DVD boots up you choose Erase and Install or something similar I can't
remember the exact wording.
Once you have installed Snow Leopard you will need to update it to version 10.6.8.
Download from here, https://support.apple.com/kb/DL1399?viewlocale=en_US&locale=en_US
Once downloaded double-click to install.
After installing 10.6.8 open the App Store Updates page and check for any other updates,
install them.
Now you should be ready to install Mac OS X El Capitan, see the instructions in my first post.
Hi again.
No. The time machine approach did not work neither.
Here´s a picture from the utility and No the disk does not disappear.
Holding down the C key for half an hour while boot from the Snow Leopard DVD did neither work as it seem like it stops rebooting half way through the DVD.
I guess that the fact that this computer is from mid 2007 the el Capitan will not work. However before I tried to update from Yosemite til El Capitan everything worked just fine.
Hi
Yosemite was installed whenI tried to upgrade to El Capitan. None of the systems seems to be installed at the moment and the computer refuses to install El Capitan although all options have been examined.
This means that even command + R and all the option mentioned there has been tried.
It seems that an unfulfilled installation of El Capitan is making obstructions.
The iMac is from mid2007. Maybe that is the reason?
However I do have a Snow Leopard available. How to use that?
Best Regards
Kurt
I have now deleted ALL data on the desk but when I try to install Snow Leopard the El Capitan shows up - even I have inserted the Snow Leopard DVD-disk in the drive???
How can I fully removed El Capitan???
It sounds like your mac is still trying to connect to the Apple Servers and trying to install El Capitan.
Remove your macs connection to the internet.
Insert the Snow Leopard DVD and Restart the mac while pressing the C key.
Your mac should now boot to the Snow Leopard DVD.
Is that the case.
Same result :(
Still trying to install El Capitan but this time I was asked to connect to internet (which I of cause did not do)
The DVD seems to react but nothing happens.
I leaves me with one question, how to remove El Capitan? I have tried everything - I think.
Best Regards
Kurt
If you Restart the mac while pressing and holding down the Command and R keys,
can you still open Disk Utility.
If you can can you see Mac OS X Base System in the left hand column.
There should be an eject icon ⏏︎ next to it, if you click on it does it disappear.
Do you know if the DVD drive in the mac works.
Have you cleaned the Snow Leopard DVD.
After inserting the Snow Leopard DVD you restart the mac while pressing and holding down the C key.
It can take a long time for the mac to boot from the DVD so keep that C key pressed down and be patient.
If you cannot get Mac OS X Snow Leopard installed then what happens when you try to install
El Capitan from the Apple Servers.
Thank you for your support. I have just started to restore (one more time) from Time Machine which I had access to on my backup desk. Have to wait another 10 hours or so before I´m able to see any result for that :)
If it does not work I´ll certainly stick to your considerations :)
BR
From Yosemite to El Capitan with no good result.
