Apple released Mojave 10.14.4 update yesterday. I installed the combo updater this morning. All went well during the install. After the initial bootup I did a Restart, I always do. All my main Apps seem to work great, all is very snappy. Besides Dark Mode capability in Safari websites, there are several fixes. There is also code included for all Apple’s new Services that were announced yesterday. I think it is a good update, go for it if you have not done so already.
