Notes on the Macintosh

I do most of my work on Macs because I like having a full Unix operating system, I like having well-integrated graphical tools, I like having hardware that's highly integrated with the software, and I like having other people worry about the system administration. The Mac is a great system, but I've also found that there are some programs that make it a lot easier to use:

Other places to look for cool Mac stuff:

LaTeX on the Mac

Option #1: teTeX through MacPorts

 sudo port install teTeX

Option #2: TUG's MacTex install

 http://tug.org/mactex/

Other things you may want:

Fixing a corrupt cache

If your mac prints this:

dyld: shared cached file was build against a different libSystem.dylib, ignoring cache
dyld: shared cached file was build against a different libSystem.dylib, ignoring cache
dyld: shared cached file was build against a different libSystem.dylib, ignoring cache

Try this:

 sudo update_dyld_shared_cache -force

Backing up a Mac

Although there are some nice programs like Carbon Copy Cloner and SuperDuper! for backing up Macs, here is an easy way to clone /dev/disk0s2 to /dev/disk1s2:

 #!/bin/sh
 asr --source /dev/disk0s2 --target /dev/disk1s2 --erase --noprompt 
 disktool -n disk1s2 backup

Changing the UID of a user

 dscl . -change /Users/bob UniqueID 501 1000
 chown -R 1000 /Users/bob

Create and mount an image on the mac

 hdiutil create -size 1m foo.dmg -fs HFS+ -volname NIST1 -attach -plist
 hdiutil detach /Volumes/NIST1/
