32Bit app Warning

macOS 10.13.4 introduces a warning when opening up a 32-bit app as part of an effort to phase them out completely in an upcoming release. If you have critical software that is 32bit only you should consider contacting your software provider or finding an alternate software product. Contact us if you would like some assistance.

Privacy Improvements

Apple's strong commitment to security and privacy continues with macOS 10.13.14 (and iOS 11.3) by including a new privacy icon that shows up whenever Apple is asking for your personal information, like your Apple ID password, so that you can verify that the request is legitimate and from Apple.
