5 Check app compatibility
Application developers are ultimately responsible for making sure that their applications and programs, such as Microsoft Office 2016, are compatible
with new versions of macOS. This means that before upgrading to High Sierra, you should carefully check the developer’s website to ensure which features are still supported.
The developers will have had access to the preview version of High Sierra, so it’s likely they will have been able to come up with a viable update but applications may not be 100% compatible immediately after High Sierra is released.
Microsoft, for instance, has advised that version 15.35 of Office 2016 will install and run in High Sierra perfectly fine but not every function works. Apple have released specific guidance about their own ‘pro’ apps (for more information head to bit.ly/pro_app_ compatibility). In brief, the following Apple pro-level apps are compatible with High Sierra: Final Cut Pro X 10.3.4 or later Motion 5.3.2 or later Compressor 4.3.2 or later Logic Pro X 10.3.1 or later MainStage 3.3 or later
If you require these apps and haven’t yet bought them, the most recent versions are available for purchase from the Mac App Store. If you already use any of these, make sure to update your system prior to upgrading to High Sierra (See ‘Update, update, update’).
If you need to check which version of an app you have on your machine, open Finder and click Go > Applications.
≈- click on the application in question and select Get Info. You’ll see the version number of the application in the General section. If you do discover any issues with Apple applications, visit bugreport. apple.com to share your feedback.
