The Safari 5.1.1 update was also installed:


X11 failure reason:

    I have got exactly the same problem since a restart after the updates installed last night. Without X11, I simply can't work.


    A replacement XQuartz does not help me either .


    Anyone out there has figured out a solution? Many thanks in advance!

    thanks for any hints to this problem...

    Until this is fixed upstream, as a temporary workaround is to use the freetype.6.dylib Universal Binary from Macports. It seems to work as a drop-in replacement, but no guarantees!


    1. Install Macports

    2. Add the option "+universal" at the end of /opt/local/etc/macports/variants.conf

         echo '+universal' >> /opt/local/etc/macports/variants.conf

    3. Use macports to install the latest freetype into /opt/local/lib with:

         sudo /opt/local/bin/port install freetype

    4. Save the old freetype version and drop in the new one:

         sudo mv /usr/X11/lib/libfreetype.6.dylib{,.save}

         sudo ln {/opt/local/lib,/usr/X11/lib}/libfreetype.6.dylib


    p.s. sorry about the Bash brace expansions, it's an annoying tic that I have to avoid typos.

    thanks a lot natchaug! It works for me with this fix.




  • danielsn Calculating status...

    Worked for me too.  I did it without doing the universal varient, and it still seems to work.  Is there any reason I would need the universal varient on 10.6?



  • natchaug Level 1 Level 1 (0 points)

    I think not, if you picked the right architecture. I was just playing it safe; the first version of freetype I tried (from Fink) was i386 not 64-bit, and failed. I presume X11 is the latter, which seems reasonable. Since the shipped version of the library was Universal, it seemed less of a headache to ask Macports to compile the same.

    Glad to know it works for you. Cheers, N.

    I had the same problem this morning.  Running the 10.6.8 Update Combo v1.1 ( forced the X11 library update on my machine.  Your mileage may vary.

    Worked a treat! nice one, thanks for posting.

    Reinstalling X11 from the DVD made it too. Check on you MacOs X install DVD, in System/Installation/Packages folder and just double click on the X11User.pkg file, then follow what's on screen.

    Hope it helps...

    i run into the same problem today.


    i solved reinstalling the previous version of /usr/X11/lib/libXfont.1.dylib i had on my system (easy task if you regularly backup your system a] with time machine, or b] with CCC configured to archive the files it updates on the backup disk).


    alternatively, replacing /usr/X11/lib/libfreetype.6.dylib with the previous version on the system worked for me. my system backed up libfreetype.6.dylib on jul, 29 2011 last time (and apparently it was not modified by the recent update which is causing the problem).


    i run an i5 imac; the weird thing is that on my other mac (an old i3) the problem did not appear. both machines run snow leopard and i updated them both a few days ago.

    hi natchaug, very good fix! Nonetheless, after doing this, when I open some PDFs in Photoshop (JUST those I needed!!), the software exits with this error:

    ... and so on. I think that having a working X11 is better than one single PDF opened in Photoshop (I could open with other programs), but I'd like to know how to restore the previous configuration.
