Hi Sebinouse and all others.
I've just finished my installation on a BOXD54250WYKH (which supports 2,5'' HDD).
Thanks for your work.
First fail, installer would not run because my Ram stick was in the upper slot > putted it in the lower >> SUCCESS
Second fail, SATA SSD get stuck after hibernate > RMA on the SATA data & power connector >> SUCCESS
Third fail, ethernet lost IP address after hibernate > MausiEthernet kext >> SUCCESS
Fourth fail > got an MiniPCIe Intel 7260 card for BT > fails on first boot > works on reboot > fails on hibernate >> FAIL
For this last fail, I couldn't mind what's happening... I've delete SSDT4.aml, remove all patches for Broadcom in config.plist.
Can you help me ?
