We are happy to report that the following Propellerhead products are compatible with Apple's new macOS High Sierra. Before upgrading to macOS High Sierra, make sure you've updated to one of the versions below.
We have had reports that Reason does not work properly under the latest macOS High Sierra 10.13.4 update. Currently, we do not recommend you to update your macOS High Sierra to 10.13.4 if you rely on using Reason, before we have fixed this.
If you have already updated to macOS High Sierra 10.13.4 and are experiencing performance issues, try deactivating the “Use hyper-threading audio rendering” function in Preferences – the General tab. This can improve the performance in many cases.
The following products are compatible with macOS High Sierra 10.13.3 and earlier:
- Reason 10/Reason Intro 10/Reason Lite 10
- Reason 9.5.2
- Reason Essentials 10
- Reason Essentials 9.5.2
- ReCycle 2.2.4
- ReFill Packer 8.2
The following products are NOT compatible with macOS High Sierra:
- Reason 9.5.1 and earlier
- Reason Essentials 9.5.1 and earlier
- Reason Limited 1.5.3 and earlier
Due to Apple’s introduction of a completely new file system (APFS) in macOS High Sierra, many older versions are not compatible. This means that Propellerhead products before Reason 9.5.2 will not work correctly after updating to the latest version of macOS. Using macOS High Sierra may in some cases even damage your documents, rendering them unusable. We strongly recommend you NOT to upgrade to macOS High Sierra if you intend to use earlier versions of Propellerhead products on your computer. Also note that if you are using the optional CodeMeter application for offline authorization (Computer/Ignition Key/Balance), please await further information regarding macOS High Sierra compatibility.
