you would like to boot your Mac normally without a USB drive plugged in you can install open core to the internal hard drive I think it's wise not to start up from a USB every time so I choose to install open core on the internal hard drive if you also want to install open core on your internal hard drive press okay this will automatically launch open core on the unsupported Mac click on install to disk just like we did before open core will build automatically but now you have to install it to your internal drive we're putting it on the Apple SSD labeled as dis zero click on the EFI partition enter your password and press okay now you can see that open core is getting installed on your iMac we need to restart the iMac one last time I don't want to press the option key every time I start my iMac open core can automatically choose the correct hard drive to start from but before we proceed to restart the Mac we need to eject the USB drive with the Ventura installer first okay we have disconnected the USB drive and now we can restart the iMac during the restart we're holding down the option key you'll notice that the icon for the drive has changed from an orange USB drive to an internal SSD hard drive icon next we'll click on the arrow and here we can choose our desired startup disc when you press the control key something specific happens the icon transforms into a rewind Arrow the rewind Arrow signifies that the hard drive will boot from this disc every time hold down the control key and choose the Ventura hard drive by pressing the arrow now you've successfully completed the installation of Ventura on an unsupported Mac if you have any questions please leave them in the comments down below if you you enjoyed this video please like share and
