    Re: Fix for making bootable Ubuntu Live USB with persistence using Unetbootin on a Ma

    I can't get this to work, i'm stuck at "write".

    Please advice.
    diskutil list

    sudo fdisk -e /dev/rdisk2

    Password:
    fdisk: could not open MBR file /usr/standalone/i386/boot0: No such file or directory
    Enter 'help' for information
    fdisk: 1> f 1
    Partition 1 marked active.
    fdisk:*1> write
    Device could not be accessed exclusively.
    A reboot will be needed for changes to take effect. OK? [n] y
    Writing MBR at offset 0.
    If i select y:

    sudo dd conv=notrunc bs=440 count=1 if=mbr.bin of=/dev/disk2
    dd: /dev/disk2: Resource busy

    Does the USB device show up on your desktop? If so run the unmount command first.

    Re: Fix for making bootable Ubuntu Live USB with persistence using Unetbootin on a Ma

    I got persistence working now, but now everything is very slow and choppy at times.

    Is there a reason for this?

    Will persistence make everything slower?

    A persistent live system is slower than a live system without persistence. You can compensate for that by using a fast pendrive. See these links

    Yes, USB devices are slower than hard drives - sort of. Especially if using USB2 devices.
    It's not as slow as having to do all previously done changes over again

    See sudodus' post above.
