Hi. At the outset I'm sorry for little delay. In /Library/LaunchAgents ("ls -l /Library/LaunchAgents") I have: total 24 -rw-r--r-- 1 root wheel 747 Jun 26 2009 com.wacom.pentablet.plist -rw-r--r-- 1 root wheel 426 Jul 14 2010 com.xrite.device.message.plist -rw-r--r-- 1 root wheel 447 Jul 14 2010 com.xrite.device.xritelegacyd.plist in "ls -l /Library/LaunchDaemons": total 40 -rw-r--r-- 1 root wheel 621 Mar 18 2010 com.adobe.versioncueCS3.plist -rwxr-xr-x@ 1 root admin 426 Jul 3 2010 com.aladdin.aksusbd.plist -rw-r--r-- 1 root wheel 443 Jul 15 2010 com.xrite.device.i1.plist -rw-r--r-- 1 root wheel 449 Jul 21 2010 com.xrite.device.i1isis.plist -rw-r--r-- 1 root wheel 415 Jul 14 2010 com.xrite.device.xritedeviced.plist Old files was updated from <http://www.argyllcms.com/osxtools.tgz>. When I type "sudo spotread" some USB error appeared and i1Pro instrument played sound. After that (second attempt) nothing happens (program suspends). Launching dispcalGUI (on new bin files) suspends too. Now in any cases instrument doesn't work (i1Diagnostic suspends too). felix ----------------------------------------------------------------- Sprawdz pogode. Kliknij >>> http://linkint.pl/f2903
