adb can't detect my sony xperia z5 compact

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:

• Charge only
• MTP (MEdia Transfer Protocol)
• PTP (Picture Transfer Protocol)
• RNDIS (USB Ethernet)
• Audio Source
• MIDI

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 tryied this solution <adb devices command doesn't show my xperia z - got proper drivers and all> on Windows without success.

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...

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.
