Refit doesn't work

[niaou73]

Hello,

I've done a dual boot on my mac book pro (late 2013 I think) and to access it I need Refit. It worked well but today I tried to re-install it and it doesn't work.
I put the the refi folder in the root level of my mac. Then I did the command 

cd /efi/refit 

then the 

./enable.sh

in the Terminal. but it responded me 

Can't delete /var/folders/zz/zyxvpxvq6csfxvn_n0000000000000/T/bless.8vwY/CF413253-A4C5-3892-991E-F5E65DA3305E/System/Library/CoreServices/.disk_label: Operation not permitted
Could not write scale 1 bitmap label file
Couldn't write label file "/var/folders/zz/zyxvpxvq6csfxvn_n0000000000000/T/bless.8vwY/CF413253-A4C5-3892-991E-F5E65DA3305E/System/Library/CoreServices/.disk_label"Couldn't bless the APFS preboot volume for volume mounted at /: Operation not permitted

And when I reboot the computer it restart normally.

If someone can help me...

 

Thank you !

 

P.S. The english isn't my language so perhaps is there some language errors. Please don't mind them.

Hi niaou73,

 

You can try rEFInd bootloader:

 

h t t p s : //www.rodsbooks.com/refind/
h t t p s : //sourceforge.net/projects/refind/files/0.11.2/

 

I have attached images with my steps here:

Yes, I finished to do it. I preferred refit but it's ok. Thank you for your help !
