Yesterday was macOS 10.14 Mojave release day!
Before you update, there are a few things you should do:
Verify that your computer can run Mojave by going Apple's support site and taking a look at the requirements.
Check to make sure that your applications are compatible with Mojave via roaringapps.com and entering the name of your application.
Backup via Time Machine or using a service like Backblaze.
Set aside some time as your computer will not be available to use as it is being updated.
Other than that, enjoy this great update! If you need help with upgrading your fleet, we are always available to assist too!
