If that's the case my only solutions are using rEFInd or updating the firmware from some other computers? Some people say the USB stick does not work because Apple disabled booting from USB functionality for security reasons. But I had a bad experience messing around with rEFInd, and I do not want to take the risk again. So I do not actually need to make a mac specific bootable USB stick. There are also a third method which uses rEFInd Boot Manager. So I followed it, but disk utility did not allow me to restore the USB from the dmg file. But I thought I would be quite similar to make a bootable USB stick for updating firmware. This one is actually for making a USB installer for OSX. But when starting my mac, it did not recognize the usb stick.Ģ) using natural osx applications to make the USB stick.
I found a lot of articles and followed them exactly, but none of them worked. (the DVDs cannot get out after inserting.) My DVD drive is broken and I cannot replace it because the exit of the DVD is broken too. I am trying to upgrade the firmware of my SSD (crucial m500) from my macbook pro (mid 2010).
Such as: Copy Crucial SSD Firmware Update ISO to Bootable USB I know there are some possible duplicates.
