CompenentsMacbook pro operating system download
Hello
I bought a used Imac (just over a year old). It is born with Lion which was on the machine when I got it.
When I tried to install the machine again I started to erase the hard drive and insert my USB key with Mountain lion that I have used on my other Macs, to create a 'Clean install'.
The problem comes at the error message I repeatedly get after a few minutes of installation. Note the computer is connected to the Internet, and I have tried both wired and wireless on several different networks.
Error message: 'Can not download the additional components needed to install Mac OS X'
I have also tried to install Lion with the USB key and get the same error message.
Next, I tried to make 'internet recovery' by pressing 'cmd + alt + R'. The installation starts.
However, I get the exact same error message again, after the computer has been running the installation a few hours!
PT, I have an Imac which can not be used for anything.
Apple Support had no other advice than to try on a different network, as they believed the error was due to the network!
I currently have tried 3 different wireless network and 2 wired and spent between 10 and 15 hours on the project.
Has run out of good ideas!
Experience or advice very welcome! ......

Apple has been making it very difficult to download & reinstall macOS recently. For best results connect the laptop directly to the router using an Ethernet cable to eliminate any possible WiFi issues.


It is possible the hard drive on your laptop could be starting to fail. Installing an OS is very stressful and perhaps it was unable to download a critical component to the drive. To check the health of the hard drive run DriveDX. If the drive shows as healthy, then post the report here using the 'Additional Text' icon which looks like a piece of paper.

FYI, using Command + Option + Shift + R should boot to the oldest compatible version of macOS still available from Apple.
