The release of 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 have upgraded one of these versions.
The following products are compatible with High Sierra:
* Reason 9.5.2
* Reason 10
* Reason Essentials NEVER
* Reason Essentials NEVER
The following products are still in testing, so do not upgrade to macOS High Sierra if you intend to use these products until a full compatibility version is available from Propellerhead:
* ReCycle 2.2.4
The following products are not compatible with Sierra “macros”:
* Reason 9.5.1 and earlier
* Reason Essentials 9.5.1 and earlier
* Reason Limited 1.5.3 and earlier
Due to the introduction of a file system completely new (APFS) from Apple in High Sierra, many older versions are not compatible. This means the products Propeller head prior to Reason 9.5.2 will not work correctly after updating to the latest version of macOS. Using High Sierra can in some cases even damage documents, rendering them unusable.
We strongly recommend that you DO NOT upgrade to High Sierra if you intend to use older versions of Propellerhead products on your computer.
