First boot I got the symbol (/), booted verbose and send to have booted fine but the screen is garbled and it looks like there is text under the loading bar, but I still have hdd activity...
I'm hoping it is finalizing the install since I haven't done a clean install of Sierra before even on my iMac.
Seems it was making the recovery partition, trying a normal boot and looking good so far, booted into Sierra fine, garbled the screen at the end of booting and looks good after it loaded 😂
