I’m wondering if anyone has run into this yet, I don’t see any posts as I search on it but maybe you figured out the answer before I did. We have Sophos anti-virus on all our OSX Macs. When Spark first starts it sends Sophos into a fit for about 2 minutes and then after that time Sophos will finally launch. If you turn off the Sophos engine Spark starts right up. Sophos obviously doesn’t like something spark is doing, I’ve tried excluding Spark but it still seems to act this way. Anyone know of a way around this issue?
