Introduzione
Ho dovuto creare una guida separata per questo modello particolare di MacBook Pro visto che monta il nuovo chip Apple T2 e richiede una procedura diversa dagli altri Laptop Mac.
-
-
Entrare nel menu Apple > Arresta il sistema.
-
Una volta spento, cliccare e tenere premuto il tasto d'accensione per 10 secondi.
-
Rilasciare il tasto d'accensione e aspettare qualche secondo.
-
Cliccare di nuovo il tasto d'accensione per accendere il Mac.

-
Entrare nel menu Apple > Arresta il sistema.
-
Una volta spento, cliccare e tenere premuto il tasto Shift sinistro, il tasto Option sinistro e il tasto Control sinistro per 7 secondi. Poi tenendo premuto tutti i tasti cliccare e tenere premuto anche il tasto d'accensione per altri 7 secondi.
-
Rilasciare tutti i tasti e aspettare qualche secondo.

Cliccare il tasto d'accensione per accendere il Mac.
Not right shift key, left. Holding the right shift key in this scenario will result in your Mac just starting up when you press the power button with the other keys down.
Thank you!!!! Every place I looked told me to hold the right shift key but it only works with the left shift key. I was going crazy.
Thanks a lot! It repaired my Macbook Pro 2018 right side USBs!
Your project is the best! Love you guys!
P.S: I used the right shift key.
Merci beaucoup !
I do not understand when you say, yes it works! What works? How do I know it won’t shut down again dropping from 45 % to 2% in a second? I have done what you said with both left and right shift key. The left key does not work…when I do use the right key and count 7 seconds and then with the power button with 7 secs, my mac air starts up after 5 seconds already…is that good. I have not dared to work further than 45 % anymore and plug int the charger again. I see the battery percentage is draining super fast and is slow in charging…like 3 hrs for a full 100%. So, I done what you said, should I risk working beyond 45% ? Every time it shuts down to 2 %, I have less battery time. This is my replacement battery from only 3 months ago. And it does have the same problem as the former battery….This is an urgent matter.

Spegnere il Mac.
-
Poi riaccenderlo e immediatamente cliccare e tenere premuti questi tasti insieme: Option, Command, P e R.
-
Si possono rilasciare i tasti dopo circa 20 secondi, durante i quali il Mac può sembrare riavviarsi.

Macbook Pro 2018, 15” (I presuming no difference in operation).
After your Mac shuts down, press and hold the right Shift key, the left Option key, and the left Control key for 7 seconds. Then keep holding those keys while you press and hold the power button for another 7 seconds.
The Macbook fires up as soon as the touchbar power button is pressed. Depressing all ⇧⌃⌥⎋ together, or depressing ⇧⌃⌥ and then adding ⎋ makes no difference. Depressing! ,-)
Nope. Doesn’t work on a 2018 MacBook Pro with Touchbar. Pressing any key boots up the computer and holding Command-Option-P-R doesn’t have any effect as it did on previous models.
Yep, new macbooks behave terribly on boot. It’s probably part of the problem. Did anyone ask for this “start on lid open” BS?
SOlution: do not press the right shift key!!!! Press all the keys on the left side of the keyboard including the Shift key- otherwise it will power on your MAc normally. IF you do the left side it wont power - do this for 10 sec then release and then power on normally- this will reset the SMC on touch bar MBP
This guide is correct. I’m not sure what you are all talking about. It’s the right shift key, left option and command. 7 seconds then add power for 7 seconds for SMC
NVRAM on 2018 DOES work, you will simply see a blank black screen, the display will shut off and then come on again. There’s no chime, but it does reset NVRAM
+1! I had the same problem where the computer would just boot up as normal on a 13” 2017 model, but this did it.
And if MBP doesn’t turn on!!??? It was slow to charge… the battery icon showed up in middle of screen when hitting any button with a red depleted battery symbol flashing even though it was plugged in. Did the SMC reset, will not turn on or respond at all. I don’t even get the dead battery icon anymore. Now what!?
Anybody knows how to do that in a MacBook Pro 13inch MBP13,3. None of those works in it…
Thanks and Happy new year!!!
i am buy new mackbook pro2018 13 inch and after open the mackbook , i found massage condeation : replace baterry , this baterry count 1 but no charge ! what i can do ?
You should probably ask your local reseller to check your device while it’s guaranteed…

Can anyone tell me where the Power Button in Macbook Pro 2018 Touch Bar is?
Hi, as said in the teardown of this machine : “The Touch ID sensor doubles as the power switch” this means it should be on the far right of the Touch Bar, unfortunately I don’t own on so that I can’t check for sure. Anyway, if it is only to start up the computer, you may refer to https://support.apple.com/en-gb/HT201150 on how to start a Mac. Hopes this helps.

Here is the correct information for how to reset SMC.
It depends on T2 Security Chip/ T1 Security Chip on your Mac.
(You can check a security chip model by pressing “option key and apple logo icon on the left upper corner on the screen and click “System information” and click “controller”.)
For T2 Security Chip;
Control: on the left side of your keyboard
Option: on the left side of your keyboard
Shift: on the right side of your keyboard
For T1 Security Chip;
Control: on the left side of your keyboard
Option: on the left side of your keyboard
Shift: on the left side of your keyboard

Bonjour, comme vu sur cette documentation officielle https://support.apple.com/fr-fr/HT201295 effectuer l’étape 2 de ce tutoriel devrait résoudre votre problème compris si l’ordinateur s’allume pendant la manipulation
