Mac OS reinstall / partitioning / newbie question

[Eurekastreet]

Hi,
I've got to reset Mac Os Sierra on my Macbook Pro (in order to hand it to someone to my family) but I have no idea how to do that.

I've tried to do it on my own I get a generic error message ("there's been a problem, please relaunch this app") at the end of the process.

I presume the partitioning of the disks might be part of the issue (see attached screenshot to see the present structure) but I have no idea what do at this point. Which partitions can be safely deleted/restored/partitioned) ?

Any help will be more than welcome.

Thanks !

Thanks for the reply. The problem I have with this is that I don't have any subfolder named "Data" and Macintosh HD is a subfolder of AFPSMedia so I'm not sure which one can/should be erased (is there a risk doing something totally wrong by deleting the wrong partitions at that point ?)

You could just create a new admin user from within osx, and then log in with it and delete your user (check the box to delete the home folder). Your applications will remain, but all your user data will be deleted.

OP:

You could do this.
But... WARNING WARNING WARNING
This will COMPLETELY ERASE everything that is on the MBP right now.
If you still want to proceed, here's what to do.
(I guarantee a very high chance of success if you follow these instructions, PRINT THEM OUT and check off as you go along)

First thing to do:
Boot to this special version of INTERNET RECOVERY:
1. Reboot and hold down together:
shift option command R
(you will need your wifi password, and it will take a while to load, so be patient)

2. When you get to internet utilities, open Disk Utility

3. In Disk Utility, check to see if there is a "view" menu. If there is, and the option is there to "show all devices", choose that. If the option IS NOT THERE, don't worry about it, and go to the next step.

4. Select the TOPMOST item in the list on the left, which represents the physical drive inside the MBP.

5. Click the erase button and choose "Mac OS extended with journaling enabled, GUID partition format".

6. Now, erase the drive and then quit Disk Utility.

7. Open the OS installer and begin "clicking through". This should install a clean copy of the OS that first shipped with the MacBook.
BE AWARE: the OS install may result in one or more reboots, and will take some time. BE PATIENT.

8. If the OS install is successful, you should see the initial setup screen "choose your language".

9. DON'T do anything more. Instead, PRESS AND HOLD DOWN the power on button until the screen goes dark and the MBP shuts off.
(If the family member is there, skip step 9 and go right to 10!)

10. Now is the time to hand it to the family member and tell them to press the power on button. Perhaps you should remain there to assist them through the setup.

This^^^
To erase your data... this is sufficient, do log out of Apple services though.

I couldn't access mac os x anymore, this was part of the issue. But it has been fixed now (through a 'hard reset'), thanks for taking the time to reply.

Sorry for the late reply, couldn't test this before today but it worked like a charm, problem solved ! Thanks!
