The recently released Reason 9.5.2, Reason Essentials 9.5.2 and the upcoming Reason 10 and Reason Essentials 10 are compatible with Apple’s new macOS High Sierra. Before upgrading to High Sierra, make sure you’ve updated to one of these versions.
The following products are compatible with High Sierra:
* Reason 9.5.2
* Reason 10
* Reason Essentials 9.5.2
* Reason Essentials 10
The following products are still being tested, so don’t upgrade to macOS High Sierra if you intend to use these products until a full compatibility statement is available from Propellerhead:
* ReCycle 2.2.4
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 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 High Sierra may in some cases even damage your documents, rendering them unusable.
We strongly recommend you NOT to upgrade to High Sierra if you intend to use earlier versions of Propellerhead products on your computer.
