adb can't detect my sony xperia z5 compact

Question

I'm trying to unlock the bootloader on my Sony Xperia z5 compact but when I have to plug the device on the computer, nothing appear to be attached:

adb devices
List of devices attached

I'm under Osx Mavericks. I also tryied on Windows 7 (sp1) without success. I enabled developer mode and OEM unlocking.

I found there adb can't detect Sony Xperia s although I installed driver that I must put my phone in Mass Storage mode, but there isn't this option in the menu, I only have:

Also, when I choose one option from this menu it doesn't seem to save it as if I close and reopen the options it resets it.

I'm on Marshmallow 6.0.1. The phone model number is E5823.

Do you have any tips? Suggestions? At this point I'm really desperate...

When I do: `adb reboot-bootloader` I have this message: `error: no devices/emulators found` — LotoLo, Aug 21 '16 at 16:56
If you don't have the connection. It's bricked. Do you see it's soft or hard bricked ? — Initerworker, Aug 21 '16 at 18:42
No I must have expressed myself badly... The first procedure to root the phone is to unlock the bootloader, it's what i'm trying to do. To unlock that I need to connect the device to the computer and then enter a command that Sony provides (`fastboot.exe -i 0x0fce oem unlock 0xKEY`. Repalce KEY with the code provided by Sony). My problem is that when I plug in my phone keeping volume up pressed I can see the blue light on the phone but the device isn't detected by the pc...

Turn off the phone while connecting it to the computer, press and hold the Volume Up key. The notification LED becomes Blue.

Install fastboot drivers. To do this, follow a tutorial with the method of your choice, and using the Unlock_SE xperia_bootloaders.zip file.
