My old mac's hdd died. It's dead. So I got a ssd and installed it in the macbook.
Now how do I get El Capitan on there? I find lots of tips online that speak of creating a bootable USB drive from the Capitan installer. But I can't download the El Capitan from the appstore because the mac has got nothing to boot from.
On my newer macbook running Catalina, I also cannot download El Capitan from the appstore because it doesn't show up when searching for it.
What I did download is El Capitan's InstallMacOSX.dmg via https://support.apple.com/en-us/HT206886
But now I need to run/open this on the old mac with the fresh ssd.
I feel I'm stuck in a loop. I need a working OS to install an OS…..
Who can help me out here?
