Recovery Partition and Facebook Integration

It may not be missing, just hidden:

Run these 2 commands in the Terminal app.

• sudo diskutil cs list
• diskutil coreStorage revert lvUUID [where lvUUID is the last lvUUID reported by the previous Terminal command.]

The recovery partition should show up again in the startup manager when you boot up with the option key.

If not then something more unusual has happened and you might be better of putting your MBP into Target mode with your Air and erasing the internal drive and reinstalling 10.11 to it from the Air.

The Facebook issue is likely because of antivirus software running (particularly Norton or Avast). They have caused this issue for others. You may need to remove it completely, but first you can try disabling firewall blocking of applications and connection blocking (or just temporarily disabling its "shields" if it's Avast!). After a restart you should be able to connect to Facebook as normal; some have even found that they can re-enable their antivirus afterwards to no ill effect.

If you don't have antivirus installed then it's a root certificate issue. There's a fix for that too - let me know...

Hello There...

Thank you for your reply. 🙂

I do not run antivirus on the Mac and the Facebook login errors occured before I installed Little Snitch. Please be so kind as to elaborate on the certificate fix.

Regarding the recovery partition, to confirm....

Logical Volume Group 7F27A5C9-C73E-4C91-AD29-1D#####

Physical Volume 1CBA00CD-C8BD-4838-AEFB-48F######

Logical Volume Family 12FAB705-57A3-4F99-BEA7-6AE1#######

Logical Volume 65F4CCBB-C457-41F3-862A-294DD#######

These are all the UUID's displayed, I'm assuming that you mean the last one "Logical Volume 65F4CCBB....."

Thanks for your reply.

Hi Sassimac 🙂

Re. the UUIDs, you are correct. The command to make the Recovery partition visible again would be:

diskutil coreStorage revert 65F4CCBB-C457-41F3-862A-294DDetc.

It shouldn't take longer than a few seconds to run.

For the certificates: there are two stages to this because it's a process of deduction. Firstly:

1. Open Keychain (by pressing CMD+Space and then typing “Keychain”).
2. Then type veri into the Keychain app's searchbar.
3. For each of the VeriSign certificates, do the following:
   • Check that the certificate is still valid (far right column) and delete it if it isn't.
   • Double-click it, which brings up it's own window and expand the "Trust" menu.
   • Make sure "When using this certificate:" is set to "Use System Defaults", not "Always Trust".

     The remaining 10 should be left at "no value specified".

If the above doesn't work, use the following steps to reset the cache of accepted certificates.

1. Open the Finder.
2. Choose Go to Folder from the Go menu.
3. Type /var/db/crls/ in the Go window.
4. Click Go.
5. Delete crlcache.db and ocspcache.db by dragging these files to the Trash (put the names in the search bar to find them)
6. Enter an administrator password if you are prompted.
7. Restart the system and test for the issue.

Post back if you have any trouble.

Best of luck,

Max.

Hello Max108...

I have tried both these solutions for Fcebook integration, and sadly they didn't work.

Any other ideas..??

Thank you most kindly for helping.

I can only think of two more approaches to this - first:

- Open KeyChain Access

- Search "Verisign"

- Remove any certificates "VeriSign Class 3 Public Primary Certification Authority - G5" under the keychain "login"

DO NOT remove the certificate by that name under the "System Roots"

The other approach is to delete your accounts database and try again (you'll have to re-add email accounts again etc. after this):

1. In Finder press shift+cmd+G and copy-paste the following in:

   ~/Library/Accounts

2. Move all files in there to the desktop
3. Try adding your Fb account again.
4. If it doesn't work, replace the files in the Accounts folder with the ones from the desktop to get your old settings back.
