    Loading Linux Mint onto 2007 White Macbooks

    Is the version of Linux Mint a 32 or 64 bit OS? Some Macs have a special chip which only allows a 64-bit OS to be MacOS. Any other 32-bit OS is allowed by the chip. Maybe you can disable the Security and/or EFI?

    Hello, Can you insert the dongle and post back a screenshot of the command 'lsusb' from a Terminal? (I assume this is a Wi-Fi dongle.) If this is an internal card the post back a screenshot of 'lspci'. This should show if the system is even recognizing the device.

    The GRand Unified Bootloader (GRUB) is used by systems to take control after the system BIOS is completed. GRUB may then show a menu to allow a user to choose from multiple Operating Systems (OS) or kernels of a specific OS. With GRUB there are many configurable settings you can make on a...
