4) Visit the AppStore to download OS X El Capitan package for installation. 5) Launch “Install OS X El Capitan.” Stick to the stages offered by the setup program tips. 6) Select the SSD disk that you wish to install the OS to, and Restart. 7) Sit back and relax while the system is doing everything else. Trying to install OS X el Capitan on a New SSD OWC 240 gig on a macbook pro 13 inch mid 2011, i also changed the battery for a new one. 1) I changed the date in terminal, to the date the download was made. 2) it started the installation process (which was great!). Answer (1 of 3): Someone else put up links to the web page where you can find El Capitan installer. And you could likely run that on a newer Mac, (or find instructions online for creating a flash drive self-installer), with your 2008 MacPro connected and booted into target disk mode. Choose to Install OS X on the formatted SSD. Follow the prompts until Yosemite is installed. Here’s link to a video on how to physically install the SSD as well as run the software installation.

I’m trying to sell a 2009 MacbookPro. It’s the model MacbookPro5.5 and Apple supports macOS El Capitan 10.11 as latest available version.
I’ve wiped all data from the installed SSD and had to boot from an external disk. Now I’ve got two problems:
- I’ve only got a Mac with Big Sur and Apple Silicon. I cannot use the package installer from the download provided by Apple to create the installer App for El Capitan. However, I need access to the installer so that I’m able to use the createinstallmedia command.
- The 2009 MacbookPro is already wiped and has only access to the recovery mode. You cannot execute the package installer in Recovery Mode to extract the media.
Luckily I’ve found this blog post from Chris Warrick who explained how to extract the installer App from the package:
- Attach an external Disk which contains the downloaded pkg from Apple. You’ll need enough space on that Disk to extract the pkg and it needs to be writeable
- Open the Terminal from inside the Recovery Mode
- Go to the mounted volume
- Extract the package:
Now we can try to create the install media from the installer app. Make sure you’ve attach another disk which can be overwritten by the installer. In this example its named „MyBlankUSBDrive“:
The InstallESD.dmg image is missing, which we’ll need to add to the right location:
Now we’ll have a valid installation medium which can be used to start the installer from. You can reboot from that disk and should be able to install El Capitan.
However, I’ve encountered another annoying issue which caused the installer to fail:
El Capitan Installer cannot be verified
Oh great… On to the next commands you can try from the Terminal inside the Recovery OS:
installer -pkg /Volumes/Mac OS X Install DVD/Packages/OSInstall.mpkg -target /Volumes/'XXX'where XXX is the name of the disk you’re installing to.- Wait for the installation to say it’s complete. You will not see any sort of progress display.
Great, you’ve got El Capitan installed! Apple had some issues with certificates and people found a way to either use the above commands for installation or you’ll have to tinker with your Macs time settings so that the signature is valid again. I would have expected that Apple resigned all installers so I wouldn’t have to use these commands at all but doesn’t look like they did.
After I got my new MBP, I decided to sell my old 2010 MBP. I wanted to keep all my existing data on my old laptop, so I decided to swap out its SSD and to put in a brand new one.
The process of installing Yosemite on the new SSD was not as straightforward as I would have liked. I thought I’d blog about it to help anyone else who needed to do the same.
Basically I was trying to sell a 2010 MBP with a new SSD, with Yosemite installed but not configured.
- Download Yosemite installation from the App store. It might complain that you already have it installed but download it anyway. It will be downloaded to /Applications and be named Install OS X Yosemite.app
- Create a bootable image from the Yosemite installer on a USB stick larger than 6GB. In a terminal run:
where MyVolume is the name of your USB stick. Change this to match the name of your USB stick.
Install El Capitan On New Ssd Hard Drive
- Physically install SSD into the target laptop.
- Insert the Yosemite USB stick into the target laptop and power up. (This might take a while.)
- When the menu finally turns up, choose Disk Utility and format the SSD as Mac OS Extended (Journaled) with a unique name.
- Once complete, exit from Disk Utility and return the main menu.
- Choose to Install OS X on the formatted SSD.
- Follow the prompts until Yosemite is installed.
