Os X El Capitan Cannot Be Installed On Macintosh Hd
6) When the 'OS X Utilities' menu comes up: Select Disk Utility and ERASE the 'Macintosh HD' drive. (This is no problem because you have your data on the other hard drive) Go back to the menu and click 'Install OS X'. The installation should go to completion without a problem. Use a Mac OS X installation Disc. If you’re unable to use Internet Recovery Mode or create a bootable USB installer, you can still use a Mac OS X installation disc. These discs are available for OS X Snow Leopard, OS X Lion, and OS X Mountain Lion. If your Mac is from 2012 or earlier, there was an installation disc in the original box. VM Type: Mac OS X and Version: Mac OS X 10.11 El Capitan (64-bit) 5) Suggest use wired Internet, not WiFi, for initial download/updates, etc. 6) Run CMD window as Administrator when entering command-line commands. 7) May need to start Virtualbox as Administrator. 8) Be patient during initial boot up. To upgrade from OS X Mountain Lion, first upgrade to OS X El Capitan, then upgrade to macOS Big Sur. Download macOS Big Sur If you're using macOS Mojave or later, get macOS Big Sur via Software Update: Choose Apple menu System Preferences, then click Software Update.
Installing El Capiton on an old Mac Book Pro today, I received the error:
OS X could not be installed on your computer
No packages were eligible for install. Contact the software manufacturer for assistance.
Quit the installer to restart your computer and try again.
I checked Apple’s support Matrix (it is a very old macbook pro) at https://support.apple.com/kb/SP728?locale=en_GB and it was listed as supported.
After lots of Googling and investigation, I discovered that the date and time were not set to current, the macbook thought it was year 2000.
