All current versions for 2018 and 2019 of CheckMark Software are compatible with Apple’s new OS – Mojave (10.14). Apple has announced that they are delaying the requirement for developers to optimize their apps for 64-bit compatibility while they continue to transition their apps. You will continue to receive notifications from Apple anytime you install a new application that is not 64-bit and every 30 days when launching the application. You can click OK on the alert and continue using the program. We are working on transitioning our apps to 64-bit and will send out an announcement when they are ready.
