I have wiped my hard drive and am trying to reinstall the operating system. I have tried installing the recommended High Sierra which keeps failing. I have a Snow Leopard disk, but it keeps crashing when installing. Please help!
Is the Snow Leopard Disc the original, a 10.6.0, or 10.6.3 Disc?
1. Start up from macOS Recovery
To start up from macOS Recovery, turn on your Mac and immediately press and hold one of the following combinations on your keyboard. Command-R is generally recommended, especially if you never installed macOS Sierra 10.12.4 or later… How to reinstall macOS - Apple Support
Command (⌘)-R
Install the latest macOS that was installed on your Mac.
Option-⌘-R
Upgrade to the latest macOS compatible with your Mac.
Shift-Option-⌘-R
Install the macOS that came with your Mac, or the closest version still available.
2. Decide whether to erase (format) your disk
If you need to erase your disk before installing macOS, select Disk Utility from the Utilities window, then click Continue. You probably don't need to erase, unless you're selling or giving away your Mac or have an issue that requires you to erase. Learn more about when and how to erase.
3. Install macOS
After starting up from macOS Recovery, follow these steps to install macOS:
If your Mac restarts to a setup assistant, but you're selling or giving it away, press Command-Q to quit the assistant without completing setup. Then click Shut Down. When the new owner starts up the Mac, they can use their own information to complete setup.
If you never installed macOS Sierra 10.12.4
If macOS Sierra 10.12.4 or later was never installed on your Mac, macOS Recovery works differently:

What is in that Install OS X" folder ?
Hi. Thank you for replying.
I have tried all of the above. After trying the internet recovery it takes me to the MacOS utilities screen. My hard drive is showing, but when I go to select the startup disk it’s not there. I found advice saying to reset the NVRAM, I tried that but it didn’t work. It says it could be a hardware issue.
Thanks again.
Yes I put a space after sudo. I can’t share what I typed in as I cannot copy and paste it. I don’t know a great deal about Terminal, but I noticed it starts with -bash-3.2# which I thought looked odd. I looked it up and it says I am logged into the Terminal as a root user which isn’t ideal. It says I don’t need to use Sudo at the beginning of an instruction. I also noticed that the line contains Sierra, but I have downloaded El Capitan. Which OS should I use?
I have tried entering the first line of text without Sudo, but it says the file “Info.plist“ couldn’t be opened because there is no such file.
I then tried the second line, it says “No such file or directory”.
I don’t know how to mount the dmg. When I go into Disk Utility it says it’s mounted.
When I double click the "InstallMacOSX.pkg" it says "This version of OS X 10.11 cannot be installed on this computer" (my iMac). I checked in the Applications Folder to see if the Installer app was there, but it's not. There is the "Install OS X" folder on my desktop, can I copy this to my flash drive?
Yes I downloaded it from Apple Support.
In the lifewire.com link it gives the text for Terminal, but I think I need to edit the path info as it's in a folder on my desktop, but I'm not sure how to do that.
I have moved the file into a folder in Applications. I've tried editing the text for Terminal, but it keeps saying "command not found". Probably because I'm not sure what to type. Just to clarify, it's a pkg file.
I've downloaded 10.13, but I have the same issue. It downloads as a dmg file, I double click it, then double click the pkg file, it then tells me it's not supported on my device (iMac 2020). On one of your links it says to quit the Installer app, but it doesn't give me the choice.
Hmmm, I'm out of data for the rest of the month, do these links work better, both should end up in same place...

Update: I tried resetting the NVRAM, but the error screen with the line through the circle. Apparently this means the wrong OS is installed. How do I download the correct one?
Hi thanks again.
I downloaded El Capitan to my external SSD, but it’s not appearing as a startup disk. I entered both lines of text in Terminal, but both times is said Sudo command not found.
