MacOS Reinstallation Hello, I tried to format my MacBook Pro 2013 through recovery mode some days back. Under disk utility, I erased data in "Machintosh HD @TT - Data" (I supposed it wasn't the one with OS files since it had a larger used volume between the two partitions). However, my MacBook wouldn't boot up again, so I attempted "repair/reinstall Catalina OS" in recovery menu. But when it downloads up to "40mins remaining", it gives an error message (and this is with a good internet connection). What can I do now? My laptop has become vegetable.

Can’t Reinstall macOS after factory reset I’m using 2017 MacBook Pro no Touch Bar. I followed all the instructions given by Apple and now I can’t reinstall macOS. I’ve tried Command+R, Option+Command+R, and Shift+Option+Command+R. When I try to install Catalina, I get pkdownloadError8. When I try to install Sierra, which is the OS my MacBook Pro shipped with, I get the message “An error occurred while preparing the installation. Try running this application again.” What should I do?
