This should no longer be needed due to a fixed installer but has valuable info that may help others in the futureMAC OSX
1. run the installer to install PlaneShift
2. find the folder /Applications/PlaneShift in finder
3. Right click [control click] on the file updaterinfo.xml and go to "open with" open the file with "textedit"
4. find the line that reads
<config active="false">to
<config active="true"> then save the file
5. if you have 10.4 or 10.5 download
http://www.psmirror.org/repo/psupdatermacosx.zip , unzip put the updater in your ps folder and REPLACE the one that is there already.
if you are have 10.3.9 download
http://www.psmirror.org/repo/psupdatermacosx1039.zip , unzip put the updater in your ps folder and REPLACE the one that is there already.
6. run the updater, it does _not_ have a gui so you will see it bounce in the dock a few times as it updates, to track the progress you can open console and see what it is doing
7. Run your psclient and verify that it will let you ingame, if it does not due to not being updated repeat step 6 till it will let you in.
