Customer Question
My MacBook is taking...

My MacBook is taking a long time to to fill in the black line and then does not move forward into starting

Technician's Assistant: Have you tried a PRAM reset on your MacBook (rebooting and holding down Command, Option, P, and R)? Or rebooting in Recovery Mode (holding down Command and R)?

I could not remember the sequence - I'll try rebooting in recovery mode and the reset. Do I have to wait until the gray line is filled with black?

Technician's Assistant: Anything else you want the Mac Expert to know before I connect you?

No, that's it

Restart your Mac

As soon as soon as it restarts, quickly press and hold the SHIFT key

Continue to hold the Shift key until you see the Apple logo and progress indicator.

Then, let go of the Shift key and let it boot to the Desktop (it may take longer than usual so please be patient).

See if it will make it to the Desktop or sign-in screen. If it does, restart and allow it to boot normally.

Then let me know the results.

Okay - previous help gave me a sequence of commands. Right now the black line is completed but no break through into start up
Mac Support Specialist: John T. F., Apple Consultant replied 2 months ago

Hold off on those other commands for a moment. Give it a few more minutes to see if it will finish booting. Many times slow booting times like this are related to disk issues or corrupted cache files.

Ask Your Own Mac Question
Customer reply replied 2 months ago
Okay I did the shift key and the progress indicator is proceeding at the same very slow pace. It's about 2/3 now and this is the very slow part of the process. Once it fills in with black, then nothing happens.
Mac Support Specialist: John T. F., Apple Consultant replied 2 months ago

Ok, see if you get a different result since you've held the Shift key down. What this is doing is putting the system into a mode called "Safe Boot". If the problem is merely with an outdated or corrupted cache or minor file system errors then this may fix it.

If it does not, we will move on to the next step of troubleshooting.

IT APPEARS THE BLACK LINE HAS QUIT 1/4 INCH FROM THE FINISH
Customer reply replied 2 months ago
It would be helpful to get a phone call(###) ###-####
Mac Support Specialist: John T. F., Apple Consultant replied 2 months ago

I can not provide telephone support but you can request it from your side and another expert may pick it up when they are available.

In the meantime, if that does not complete, then try this;

Shutdown your Mac.

Restart and, immediately, press and hold the “OPTION” (or “Alt”) key at boot until the boot menu appears.

Then, select the “Recovery" volume.

(Alternative: If the above doesn’t work… Restart, hold COMMAND + R keys until you see the Apple logo and progress indicator. If neither of those work, try COMMAND + R + OPTION.)

Wait for “macOS Utilities” menu to appear (DO NOT CHOOSE TO INSTALL)

Choose Disk Utility from the available options.

In Disk Utility, select your normal, bootable hard drive volume from the list in the sidebar (usually "Macintosh HD").

Then, Click “First Aid“.Next, click “Run”, if requested. (You may need to click “Mount” first if First Aid is not highlighted. If you do not see “First Aid” then click “Repair Disk”.)

If it finds errors, repeat the process until it reports the drive is OK. Then you can click “Done” if requested.

Once the process has completed, choose “Disk Utility” > “Quit Disk Utility” in the menu bar at the top of the display.

Then, restart your Mac and it should hopefully boot back into your normal Desktop.

MAC OS UTilities are up and I selected disk utility buy am not able to make anything happen. My mouse does not show up to click continue, nor does hitting return
Mac Support Specialist: John T. F., Apple Consultant replied 2 months ago

Is your mouse wired or wireless?

Ask Your Own Mac Question
Customer reply replied 2 months ago
Wireless - I’m reading your comments from a Mac laptop. The desktop MAC was new in 2012 and I might have the wrong name - has a 17 inch wide screen
Mac Support Specialist: John T. F., Apple Consultant replied 2 months ago

Is this mouse a third-party mouse that requires a USB dongle or an Apple mouse?

Still have the disk utility up, just can’t click continue
Mac Support Specialist: John T. F., Apple Consultant replied 2 months ago

Ok,

Power off the Mac.

Unplug the Mac's power cord.

Wait fifteen seconds, minimum.

Attach the Mac's power cord.

Wait five seconds, then press the power button to turn on the Mac back on.

Once that is done, repeat the process to try and run Disk Utility:

immediately, press and hold the “OPTION” (or “Alt”) key at boot until the boot menu appears.

Then, select the “Recovery" volume.

(Alternative: If the above doesn’t work… Restart, hold COMMAND + R keys until you see the Apple logo and progress indicator. If neither of those work, try COMMAND + R + OPTION.)

Choose Disk Utility from the available options.

I usually keep my computer on at night in sleep mode -- shut it down last Friday morning and it has not started since.
Mac Support Specialist: John T. F., Apple Consultant replied 2 months ago

Ok, power off once more.

restart and, immediately, press and hold the COMMAND and S keys together. When the screen flashes and goes black and you start seeing text appear on screen, let go of the keys.

After a short period of time you will land at a command prompt (similar to :/root#) or it may stop on an error.

Let me know which you arrive at.

Ok.

If you can make it in - Can you tell me the exact version of macOS you are currently running on your Mac, please?

Click the Apple logo in the menu bar at the top left of the screen

Select "About This Mac"

In the window that opens, look for the "Version" information. Please let me know what it says.

will this corpse crashing continue for a long time?
Customer reply replied 2 months ago
I've saved some files in drop boxes
Mac Support Specialist: John T. F., Apple Consultant replied 2 months ago

Ok, if you are signed into iCloud on the Mac then it's likely *some* info is synced but documents and the majority of your system would NOT be backed up.

The problem you are having is that a portion of the operating system on your Mac has crashed, resulting in a lot of defective or dead software processes being created over and over again at startup (in this case, referred to as corpses). This is why it never completely makes it to the desktop because it is stuck in this state.

The only guaranteed method for recovering from it would be to restore an earlier back up, which you do not have, or attempting to erase and re-install macOS. This requires being able to get to the 'macOS Utilities" screen you saw earlier but could not use the mouse.

If you do not have info you would like to save then I would recommend trying to come up with a wired mouse to make this a bit easier OR if you do have data you wish to preserve then it's going to need hands on assistance by an authorized service center.

Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill
