I am running OS X v10.10. I am about to install the latest version of Skype on my iMac, but I am forewarned of possible problems (e.g. "libflavors", etc.) that may cause the unit to crash. Furthermore, the installer wants access to my keychain and I am getting adware popups so I am reluctant to grant access. Skype community is terse and divided on what best to do. Any thoughts or cautionary advice?
