That tricky single processor G5 1.8 ...
While an inside source has pointed out to us that 10.4.3 would indeed fix various problems with Tiger and the "1.8 GHz Power Mac G5 (late 2004) systems", MacFixit today says the opposite
. Since we haven't got word from actual users of 10.4.3 8F46 that have access to such a machine, we can only say that as of today, all information is not enough. Apple still says that an update is in the works
for those machines, but it might need a separate firmware update in order to fix everything.
