macbook pro black screen problem

macbook pro, 15 inches, screen is black after failed wakeup from sleep.

https://macpaw.com/how-to/fix-mac-black-screen

it works when connects to an VGA monitor.

Run disk unility, fixed volume issue, restart, still black screen.

===============Tried this, still black screen===========

Reset your Mac’s NVRAM settings

NVRAM stands for non-volatile RAM and is basically a functionality that stores in memory settings for display, speakers, primary startup disk etc. Everything even remotely connected with boot process (like your MacBook won’t turning on) can be set back to factory settings during the NVRAM reset.

To flush NVRAM settings:

1. Shut your Mac down.
2. Press the Power key.
3. Wait for your Mac to start loading.
4. When you hear a startup sound, hold down Cmd + Option + P + R.
5. Keep pressing the keys until you hear a second startup sound

==================================

Zap your Mac’s SMC settings

SMC is System Management Controller. What it controls is temperature, lights, keyboard, fans, and many other side-processes. According to Mac support forums, resetting SMC helps in 90% of the cases when your Mac’s screen goes black. To perform this trick follow the tips below.

For a MacBook with a non-removable battery:

1. Shut your Mac down. 
2. Connect your Mac to a power outlet. 
3. While your Mac is still shut, Press Shift + Option + Control and Power key at the same time. 
4. Let go of the keys and boot your Mac again.

==================================

Update OS X system

https://support.apple.com/kb/DL1969?locale=en_US

Downloaded high Sierra dmg file. Installed. Restarted not responding after 3-5 minutes.

A CA file has been bootstrapped using certificates from the SystemRoots

keychain. To add additional certificates (e.g. the certificates added in

the System keychain), place .pem files in

  /usr/local/etc/openssl/certs

and run

  /usr/local/opt/openssl/bin/c_rehash

This formula is keg-only, which means it was not symlinked into /usr/local.

Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries

Generally there are no consequences of this for you. If you build your

own software and it requires this formula, you'll need to add to your

build variables:

    LDFLAGS:  -L/usr/local/opt/openssl/lib

    CPPFLAGS: -I/usr/local/opt/openssl/include

    PKG_CONFIG_PATH: /usr/local/opt/openssl/lib/pkgconfig

parallel can cause all kinds of trouble.

You may want to get winetricks:

  brew install winetricks

By default Wine uses a native Mac driver. To switch to the X11 driver, use

regedit to set the "graphics" key under "HKCUSoftwareWineDrivers" to

"x11" (or use winetricks).

For best results with X11, install the latest version of XQuartz:

R GEO paring problem on osX

Working with R GEO on osX, somehow the GEO object cannot be parsed. I then update GEO to the most recent version. Problem persisted.

After restarting the computer, everything seems fine. Not sure what have happenned.

turn on ssh login in osX

The Apple Mac OS X operating system has SSH installed by default but the SSH daemon is not enabled. This means you can’t login remotely or do remote copies until you enable it.

To enable it, go to ‘System Preferences’. Under ‘Internet & Networking’ there is a ‘Sharing’ icon. Run that. In the list that appears, check the ‘Remote Login’ option.

This starts the SSH daemon immediately and you can remotely login using your username. The ‘Sharing’ window shows at the bottom the name and IP address to use. You can also find this out using ‘whoami’ and ‘ifconfig’ from the Terminal application.

vertical strips on 17in mac pro laptop

Today, my 17inch mac pro laptop (5 years old now, hostname "ace") has a vertical strip in the middle. (It occurred once in the spring 2015, but went away on its own).

After some online research, I pressed the glass screen for a few second, and restart by holding CMMD+Ctrl+P+R. The vertical strip went away.

Pressing the glass screen was mentioned at
https://www.ifixit.com/Answers/View/17589/MacBook+suddenly+has+inverted-flickering+vertical+strip+on+the+screen

CMMD+Ctrl+P+R was mentioned at
 http://www.cnet.com/forums/discussions/macbook-pro-screen-problems-strip-screen-then-shutdown-588409/


Later in the afternoon, the same vertical strip come back again, after some overheated use.
I tried press the glass and CMMD+Ctrl+P+R again. The vertical strip was still there.
