E7270: target partition not visible for Sierra installation

[Jake Lo]

AppleHDA_ALC293 is not caching. Run these again until you see it showing in the output

 

sudo touch -f /L*/E*

sudo touch -f /S*/L*/E*

sudo kextcache -Boot -U /

I've run this now 12 times
sudo touch -f /L*/E*
sudo touch -f /S*/L*/E*
sudo kextcache -Boot -U /
 
cant see AppleHDA_ALC293 mentioned in the output - I've overwrite the file as well and did a
sudo chmod -Rf 755 /L*/E*
sudo chown -Rf 0:0 /L*/E*
sudo chmod -Rf 755 /S*/L*/E*
sudo chown -Rf 0:0 /S*/L*/E*
sudo touch -f /L*/E*
sudo touch -f /S*/L*/E*
sudo kextcache -Boot -U /
 
after that 5 times
sudo touch -f /L*/E*
sudo touch -f /S*/L*/E*
sudo kextcache -Boot -U /
 
same its not mentioned in the output
 
may its really time to start from scratch ^^?
 
 
UPDATE:
 
After a remote Session with Jake its working - its looks like that the Audio driver was damaged.
 
I'm looking now for a Bluetooth adapter and wlan stick!
 
Many thanks for your time !
