We have installed 6.0.14 and freezing is, unfortunately, still a big problem. Also, restarting the mac triggers a 90 seconds wait before the system shuts down, probably due to wait for processes to terminate? Uninstalling ESET remedies both problems, so CyberSecurity is defenately to blame. Our computers are running OS X 10.6, 10.9 and 10.10 all experiencing same problem (latest software update on all OS). Internet connection freeze can only be remedied by restarting. Logout and login does NOT help! Problem typically experienced after system sleep/wake.
