Hi Everyone - So I just downloaded Meta Z to add Metadata to by Blu-Ray files and something very weird started to happen on my iMac. 1) It says the App wasn't recognized and not from an Identified Developer...I continued to download. 2) My computer started acting slow once I opened the app, the rainbow wheel was spinning, Apps were bouncing...so I deleted it. 3) I also went into the Library and deleted anything associated with it. I'm concerned my iMac was exposed to Malware or some type of virus? Is anyone else familiar with Meta Z? Is it legit? After deleting it my computer seems to be acting normal again. Now I'm wondering if I should do a complete Factory reset or if I'm fine. Any help would be appreciated - thanks!
