It's apparently an old issue but I just became aware while looking in Console that the HAPS software that X-rite installs for i1Profiler on Mac crashes every few seconds. X-rite even has a very old page discussing this (http://www.xrite.com/product_overview.aspx?ID=1469&Action=support&SupportID=...) yet they haven’t apparently fixed this in their installer for i1P (I did a new install to verify this, 1.5.6). I had to go to the page below, download a new HAPS installer (Sentinel_Runtime). Now NO crashing every 10 seconds: http://sentinelcustomer.safenet-inc.com/sentineldownloads/?s=&c=End+User&p=S... If you're on Mac, you might want to check Console and look for this crash, update the software found above. Andrew Rodney http://www.digitaldog.net/
