Yes, this probably has to do with SIP being enabled, which blocks libraries stored in /usr. This was a pretty common issue that people had with v6. You can try disabling SIP via http://osxdaily.com/2015/10/05/disable-rootless-system-integrity-protection-mac-os-x

Subject: [Freesurfer] Lazy_symbol_error libstdc++.6.dylib: stable Version 6 Release

        External Email - Use Caution        

Hello Freesurfer Developers,

I was attempting to use the mri_cvs_register command ( mri_cvs_register -- mov subjid  -- mni) and I received this error:

asegfname aseg

Using m3z type morph files.

dyld: lazy symbol binding failed: Symbol not found: ___emutls_get_address

  Referenced from: /Applications/freesurfer/bin/../lib/gcc/lib/libgomp.1.dylib

  Expected in: /usr/lib/libSystem.B.dylib

dyld: Symbol not found: ___emutls_get_address

  Referenced from: /Applications/freesurfer/bin/../lib/gcc/lib/libgomp.1.dylib

  Expected in: /usr/lib/libSystem.B.dylib

Abort 

I resolved the issue by downloading the Freeview_6.0.0_MacOS patch, but a new error came up :

 Error opening file dyld: lazy symbol binding failed: Symbol not found: ___emutls_get_address

I did not find similar errors in the archive. Should I disable SIP? Could you help me trouble-shoot this error? 

My freesurfer is installed on an external hard disk and I am processing my subjects on my Mac desktop.
