Trusteer Rapport says it's compatible with OS X but OS X prevents it from installing. why?

Rapport is worthless on a Mac. I suggest you avoid it.

You do not want any 3rd party Anti-Malware products (they are redundant to the build-in Mac OS X anti-malware features), you do not want any Mac cleaner apps (they interfere with normal Mac OS X operations), you do not want any Memory Cleaner apps (they interfere with Mac OS X memory management).

Plus the above 3rd party category of apps have been responsible for more complaints about poor performance and system panics than any other single source (except maybe Geneio which is in its own category of evil).

I've used Trusteer Rapport for about 3 years. When Apple forced me to go to 10.10 from 10.6, I thought I would re-install Trusteer Rapport to "top-off" my internet security.

Thanks for the information and recommendation BobHarris - I hadn't considered that Trusteer Rapport:

• would be redundant to the build-in Mac OS X anti-malware features;
• could interfere with normal Mac OS X operations;
• interfere with Mac OS X memory management.

I'm going to wait on installing it and read more on how OS X works in those ways.

Add-on anti-malware tools are a common source of performance problems, of instabilities, and they often don't and won't catch much of the malware that's around. They can also cause security problems, as various anti-malware tools are themselves ripe targets for security attacks.

OS X contains the integrated Xprotect tool and some related bits, which are automatic and maintained by Apple. Also avoiding having Adobe Flash Player and Oracle Java installed — or having the plugins for those tools blocked — can do quite well. That, and download stuff from the app store, not from random sites around the 'net.

As for your question about Trusteer, I would suggest asking the vendor; the folks at Trusteer.
