Will I have to reinstall each unix program? If you upgrade to Panther, it shouldn't. It might be that you need to recompile some stuff to get it to work, but as a general rule this shouldn't be required. But, based on experience, I would recommend to at least perform an Archive and Install. I've done 100+ "upgrades" from 10.1 -> 10.2 -> 10.3. And, doing the upgrades has given me flaky results many times. I thus prefer the "clean upgrade" solution you get with either an Archive and Install or format + install. But, alas, YMMV :) Tor
