Hi, my name is David, and I will do whatever I possibly can to help answer your questions.


Have you tried accessing Startup manager, to see what is detected or not detected?


Hold down Option (Alt) at startup for Startup Manager, and let me know what disks you see.


Sincerely,
David.

I see two discs, one says macintosh hd, and the other, restart hd

Expert:  David replied 1 year ago.
Hi,

Chose the Recovery HD, and an options screen will load.

Then choose Disk Utility in the options list.

In Disk Utility; click Macintosh HD, and click Repair Permissions.

When that is done, click Repair Disk.

After that, quit Disk Utility, and choose startup disk as Macintosh HD.

If the issue remains, reboot to Recovery Disk again, using the Option key at boot. Then in Disk Utility, select the item just above Macintosh HD and click Repair Disk. Try again with normal startup.

If this fails, hold Command - V at startup, and give me the last few lines of text that appear.

Sincerely,
David.

I tried the first two things, they didnt work, but each time i restart and press command V it goes to quick to see what is written in black and white, so how long should i hold down the two keys for?

Hi,

It would help if it froze on the text, it might give a clue. It isn't and we can't do anything about that.

Did the Disk Utility give you an error message?

What did it say specifically?

Sincerely,
David.
Customer: replied 1 year ago.

Expert:  David replied 1 year ago.

Expert:  David replied 1 year ago.
Hi,


yes, but is it what you see at startup, or is it the error you get from Disk Utility?


Where do you copy that error from?


Thanks


Sincerely,
David.
Customer: replied 1 year ago.

when i startup, i press command V and it goes directly to there, then after a few seconds, it logs me back in automatically.


 

Expert:  David replied 1 year ago.
Hi,

So you can login now, is that correct?

Also, did you run Disk Utility? And did it give you errors or an error, and if so what did they say?

Sincerely,
David.
Customer: replied 1 year ago.

Hi,

What about when clicking 'Repair Disk'?

Did you say it was possible to login after doing that?

Sincerely,
David.
Customer: replied 1 year ago.

yes

Expert:  David replied 1 year ago.
Hi Clemente,


It was late here in Ireland, I only see your reply today.


That is good, that means repairing the startup volume, using Disk Utility, repaired the corruption of whatever startup files became corrupt.


Now that you can login, you should do some follow up maintenance. This will confirm the issue is resolved, and repair any problems that still remain.


When you are at your Desktop, click the  in the top left, and click Software Update.


When it searches, if it finds anything install it.


Once updates are installed, and it finds no new updates, open /Applications/Utilities/ and launch Disk Utility again.


Select Macintosh HD and click Repair Disk. When it finishes, please click Repair Permissions.


This should see your issue totally resolved. Feel free to ask me any follow up questions.


Yours sincerely,
David.
