Subject: Re: Temperature calibration & relax @ Mac OS X 10.7.3 „Lion“
Hi,
Unfortunately not yet - I'm still trying to work out how I can
reproduce this problem! On my system, also 10.6.8, the relax DMG file
execution is working fine. So I have to work out what is breaking it.
Development on the Mac is difficult though, and it takes much longer
than on other systems. Are you using the DMG distribution file as
well? Could you give more information (copy and paste messages, etc.)
about the problem? The more information I have, the easier it will be
for me to find the exact point of failure and fix it. Also, what is
your system architecture? It should be one of ppc, ppc64, i386, or
x86_64. If you or Martin could create a bug report with all
information possible, this would also be of great help (see
https://gna.org/bugs/?func=additem&group=relax).
Cheers,
Edward
