On the plus side it does have a very good hit rate on malware. Like you I am mainly OS X but job also involves coding on Windows and Linux.
Anyway glad we got it resolved. Thanks for bearing with me as we worked it out.
So my problem WAS comodo. Even after checking my trusted files, adjusting my behavior exclusions etc nothing. So I stopped the service, restart, ran the patcher, it worked, set the service to start, restarted and bam fully functionally VMware Workstation.
Thanks for being here to debug. I respect developers that support all of their projects. Ive met / seen developers put out something like this and NOT support it by being available because "its so simple it should always work and if it doesnt its the user" and while thats true on windows half of the time, its sometime conflicting calls or old code that does it too.
Im glad theres another OS X user out there. Getting sick of people saying OS X is for "noobs and the rich". I love OS X for the GUI and Unix Core. Ill always have OS X as client / desktop and unix / linux as backend / servers.
