Major MacBook Pro Power Issue!

For the past few hours my MacBook Pro (with touch bar) will not power on without first going through the Reset System Management Controller (SMC) (where one must press Shift-Control-Option, then press the power button, then hold the keys for about 10 seconds). This only occurs when the lid is closed, it does not when left open and goes to sleep.

I really need my Mac to be able to just power on when the lid is opened.

Any and all assistance is greatly appreciated.

Thanks,

Matthew

Hmmm. The SMC would be the go to way to address such issues.

You can

Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379

1. Shut down the computer.

2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.

3. Press and hold the Command-Option-P-R keys.

4. Turn on the computer.

5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.

6. Release the keys.

To trouble shoot further you can:

Try a SafeBoot https://support.apple.com/en-us/HT201262

Takes noticeable longer to get to the login screen as certain system caches, dynamic loader cache etc get cleared and

rebuilt. This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.

Test issue in another user (or guest user) account https://support.apple.com/en-us/HT204443

This will tell you if it a universal issue or isolated to your user/admin account.
