<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Folks,<div><br></div><div>Since we are close to the release date of Snow Leopard, let me list a small number of very minor TeX issues you might run into when upgrading, and describe fixes. Aside from these issues, TeX and TeX programs and utilities run fine. (These minor issues are fixed in MacTeX-2009, now undergoing testing.)<br><br></div><div>In Snow Leopard, Apple's own applications run in 64 bits on machines with 64 bit processors. So System Preferences runs in 64 bits and thus requires 64 bit plugins. The TeX Distribution Preference Pane in MacTeX-2008 has only 32 bit binaries (the version in MacTeX-2009 has both 32 and 64 bit binaries).</div><div>However, System Preferences in Snow Leopard understands this problem, and when it finds a 32 bit pane it puts up a dialog saying "to run this Pane, System Preferences must restart". When you click OK, it restarts in 32 bit mode and runs the Pane. So the problem is "cosmetic only."<br><br>Apple changed the configuration of "man" slightly, so TeX man pages may not be found from a shell. But this is also easily fixed. Go to the TeX binary directory and create a symbolic link named "man" to the man pages. Thus the following commands will fix the problem:<br><br><span class="Apple-tab-span" style="white-space: pre; "> </span>cd /usr/local/texlive/2008/bin/universal-darwin<br><span class="Apple-tab-span" style="white-space: pre; "> </span>sudo ln -s ../../texmf/doc/man man<br><br></div><div>When you upgrade to Snow Leopard in the standard way, TeX Live 2008 and Ghostscript should be preserved, but it is possible that the symbolic link /usr/texbin will be destroyed. If your front end cannot find TeX, recreate this link as follows:</div><div><br></div><div><span class="Apple-tab-span" style="white-space: pre; "> </span>cd /usr<br><span class="Apple-tab-span" style="white-space: pre; "> </span>sudo ln -s ../Library/TeX/Distributions/.DefaultTeX/Contents/Programs/i386 texbin<br><br>If you run into some other difficulty I have forgotten, please write this group. After we collect such "Friday, Aug 28 Experiences", we'll write an addendum to the MacTeX web page if necessary.<br><br>Dick Koch<br><a href="mailto:koch@math.uoregon.edu">koch@math.uoregon.edu</a><br></div></body></html>
