MacBook Pro CAN'T FIND STARTUP DISK/Hard Drive!! Help Please ToT

I need URGENT HELP PLEASE!


I have a MacBook Pro 2014. So I forgot my login password after about a year of not using my MacBook. I clicked on the “restore from Apple ID” or smth along those lines, so that I could change it. I was surprised this was an option though, since I had signed my Mac out of my Apple ID long ago.


As soon as I clicked on this, my Mac went into recovery mode. And my Mac had not been able to reboot from my startup disk. (It literally will not register it at all)



So I tried some trouble shooting, and restarted my MacBook, holding down the option key. I was happy to see my HD Drive shows, but when I click on it it takes me right back into recovery mode and it can’t find the drive. It literally has a blank for my “Startup Disks” and in First Aid the only thing that pops up is disk 0 OS X Base System.


So to put it simply, how can I get my “ashaisthebest” drive to show up under my startup disks/disk utility? My Mac can only find the drive after I restart using the option key. But I have no idea how to reboot it using that disk. Any ideas?

Try a PRAM Reset. Sometimes a Mac will get confused as to which boot option it should be doing and a PRAM Reset will remove any boot options stored in the NVRAM so the laptop will need to search for a bootable volume (hopefully the internal drive).


2) If I were to erase the Mac completely, would this also solve the issue? Or would I still not be able to get to the login screen due to this drive issue?

If you erase the Mac, then you will destroy all the data on the SSD which has not backed up.


If you want to perform a clean install of macOS, then you will need to boot into a macOS 10.13+ installer since a third party NVMe SSD is installed in the laptop. Since the SSD icon is showing up as orange I believe your laptop has an OWC SSD which needs a firmware update in order to work with macOS 10.14+ (the orange icon is a sign which I've only seen under these conditions). This means you either need to attempt to boot into Recovery Mode using Command + R to see if it will boot into installer for the currently installed OS, but unfortunately some Macs will only boot into the oldest version of macOS regardless of the keys used which seems to be the case with your laptop since your screenshots show a pre-macOS 10.13 OS in Recovery Mode.


Another option for a clean install is to create and use a bootable macOS 10.13 USB installer if you have access to another Mac able to run macOS 10.13. If you cannot access a macOS 10.13 installer, then you will need to install macOS to an external drive and upgrade the external drive to macOS 10.13 so that you can run the SSD firmware updater and so you create a macOS 10.13 USB installer so you can perform a clean install of macOS to the internal SSD (macOS 10.14 if the SSD's firmware is updated).


Personally I believe you should try the steps I outlined in my previous post to attempt to reset the password or to create a new admin user account assuming you can boot into Single User Mode so that you can reset your original account password. The first option requires Filevault to be enabled while the second option cannot have Filevault enabled since we need to access the data on the drive to trick macOS into running Setup Assistant again. Both of these options will leave all your data, apps, and settings intact if successful.


Edit: Here is a link to the instructions for performing a PRAM Reset (hold the reset for at least three chimes if possible):

I believe your laptop has a third party NVMe SSD installed which is why you can see the SSD on the Apple boot picker menu (Option Booting), but not within Disk Utility of macOS 10.12 or earlier because an NVMe SSD requires the use of macOS 10.13+. Since the SSD is appearing as an external drive with the orange icon I think you have one of the early model OWC Aura SSDs which require a firmware update:

https://eshop.macsales.com/Service/Knowledgebase/Article/10/730/Aura-SSDs-Firmware-Update


If you cannot boot or log into an admin user account on this laptop, then you have two options. One is to install macOS 10.13+ to an external drive, boot from the external drive in order to run the OWC firmware updater. You can try booting into Internet Recovery Mode using Command + Option + R to attempt to access the Big Sur online installer, but unfortunately sometimes this key combination will only boot to the original OS that shipped with the laptop which is too old for use with your third party SSD. If you have access to another Mac capable of running macOS 10.13 to 11.6, then you can create a bootable macOS USB installer using the instructions in this Apple article:

https://support.apple.com/en-us/HT201372


Or you can trick macOS into running Setup Assistant again so that you can create a new admin user account using these instructions:

https://discussions.apple.com/thread/253142995?answerId=255904918022#255904918022


If Filevault is enabled, then the latter option won't work, but you may be able to reset your existing user account password using instructions in this Apple article (see about half way down the article):

Thank you, I asked my previous repair shop (It was water damaged years ago and they had to replace the hard drive) and he confirmed that there is indeed a third party SSD installed. Thank you for your tips. I will check them out.


Further Questions: 1. Do you know what could have caused this malfunction? Or what the usual cause is?

2) If I were to erase the Mac completely, would this also solve the issue? Or would I still not be able to get to the login screen due to this drive issue?
