Patrick Atis securely wiped his drive, and then wanted to reinstall Yosemite, the installer for which he has on an external hard drive. However, after he booted into OS X Recovery (holding down Command-R at startup), he was only offered the option to download OS X through the App Store, and Yosemite wasn’t an option. What path could he take forward?
It is a successor to Mac OS Yosemite and forms on performance, and security more following in northern California, the final version and latest version of Mac OS X El Capitan was released under the name of OS X was announced by macOS Sierra, and the first beta Mac OS X El Capitan was released to developers on WWDC year 2015, by the passage of.
Recovery will reinstall the same version of OS X that was on your Mac, even though it’s been erased. Patrick should therefore be prompted to install Yosemite. That didn’t happen in his case. With an erased 2009 MacBook Pro, as Patrick has, he can’t use Internet Recovery, which will reinstall the original operating system that came with the Mac. If that had worked, you could install that older OS, then copy the Yosemite installer, and use it to upgrade, although an intermediate OS X installation might even be required.
Since this isn’t working for Patrick, the better course is to create on another Mac a bootable Yosemite installer following Dan Frakes’ instructions. Patrick has the Yosemite installer, but if you need an older installer, you can launch App Store on a Mac and then use the Purchased tab to scroll down and find older releases—they don’t show up by searching.
- Follow these instructions, At Section 4 download InstallMacOSX.dmg. When that has downloaded open it and you will get InstallMacOSX.pkg. Double-click on that and an installation window will open, this will convert InstallMacOSX.pkg to the. Install OS X El Capitan.app which will be in your Application folder.
- I created a USB disk with a bootable El Capitan as per this documentation. Plug-in your USB key on a turned-off computer. Start your Mac, press immediately OPTION (aka ALT) Select the Orange icon (aka a USB stick) labelled El Capitan. If it does not detect it after 10 sec and you only see your hard-drive. Try another USB port and wait 10 sec again.

If the mac has no operating system on it you can use another mac that you know can run El Capitan to download
the El Capitan installer Disk image.
Click on the link below.
Go to Download OS 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.)
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.
Read the instructions here,
Install El Capitan Os
If you do not have access to another mac that can run El Capitan then do you have a copy
of the Mac OS X Snow Leopard DVD install disk.
Install Snow Leopard from the DVD, update it to version 10.6.8.
When you have updated SL to 10.6.8 open the App Store Updates page
and install any other outstanding updates.
