Hello, I’m installing OS -X Lion on my 13” MacBook Pro, but it stuck at “downloading additional components” and it says 46 hours left. It’s already more then 7 hours that I’m waiting and I don’t think it s normal. There is also the little circle running since yesterday night … what should I do? Reinstall the OS again? thanks
Often the issue is a poor internet connection so the installation fails. But you have a second issue here which makes this even harder! Apple uses a certificate within the installer which the installer uses to validate it before it tries to install. It uses a date window and will fail when the systems date is outside of the window! Here’s a good writeup on this If you’ve got an old macOS install image, it will probably stop working today & How to get an old macOS installer from Apple. Apple doesn’t update the older OS’s certificates any more. So you either need to get an updated OS installer (new certificate) if you can use a newer OS or you need to fake-out the installer making it think its back in time! You still need the OS installer on a local bootable drive so make sure you’ve done that. Then disconnect your Mac from the internet and alter your systems data as outlined here:
Run the installer and you should be set!
