I'm not so sure what your question has to do with reported performance issues on newer Macs with Logic 9.1.2, but I just loaded an instance of Autotune Evo in LP 9.1.2 here and it was fine. Care to elaborate - not least of all so that I can give your question a thread of its own.antares plugins autotune evo/sybil are pointing me to update to the latest version, and they won't open. i already have the latest version. am i screwed?
Could you post a screenshot of the message? Have you had a look at the AU Manager? If you try to re-validate the Antares Plugins, make sure that Logic is running in 32 bit mode. You could have a look for Antares Preferences and caches and maybe moving them out of their respective folders, look at repairing permissions - the usual troubleshooting stuff.i updated logic to 9.1.2 and now my antares plugins don't work. for example, when i open autotune evo, it fails to load and then it prompts me to update them. i already have the latest versions.
