Macbook 12" 2016, m5
macOS El Capitan 10.11.5
Apple Multiport adapter + USB-C -> USB A adapter.
Hi,
recently I wanted to reinstall my Macbook retina and I have a problem with booting from usb thumb drive. I have a genuine Apple Multiport adapter and a 3rd party USB-C -> USB A adapter. When I connect the drive with both of these, and select USB booting, MacBook shows "Unsupported icon" and won't boot.
On other macs I own, the same thumb drive boot without problems.
Has someone simliar problem, or do you have a clue what can cause this problem ?
Thanks!
MacBook, OS X El Capitan (10.11.5), null
