MacBook Pro start up process take too long

I have a MacBook Pro from 2013 that is currently on the High Sierra and it has a 13" screen size. I like to use my computer almost every day so I dont find it necesssary to turn it off all the time, it is easy to just put it ot sleep and close the lid.

Yesterday, I turned off my computer but when I wanted to turn it back on again it wont start, it will only let me to enter my password. The the start up process bar is at 100% but nothing happen.

Also, I try to run a Fisrtaid to my Macintosh HD by pressing Command + R, but the disk appears in grey color and it display a message saying that the disk is NOT MOUNTED, is this the problem?

Does anyone knows how to deal with this problem?

Thakn you!

Hi Jorge,

The reason why Disk Utility can’t automatically mount your startup disk is because it is encrypted by FileVault. When you boot your MacBook normally, it doesn’t immediately boot your startup disk; instead, it boots the Preboot volume on your Mac so that you can unlock your encrstartup disk and start the actual boot process.

To mount your startup disk in Disk Utility, select Macintosh HD, then click the Mount button. Enter your login password when prompted. If successful, the First Aid button should no longer be grayed out and Disk Utility should indicate that your startup disk is mounted.

In regards to your MacBook not booting all the way and logging you in, try reinstalling macOS onto your MacBook. No data will be lost unless you erase your startup disk in Disk Utility.

Hope this helps!
