Native Instruments has conducted initial compatibility tests with pre-release versions of Mac OS X 10.7 Lion, and has found an issue that causes the 64-bit versions of NI applications to cras,h both when used stand-alone and as a plug-in.
The cause of this issue has been identified and updates for the affected products are currently in development, with their respective release planned for September or earlier.
In the meantime, NI recommentds that you utilize the 32-bit versions of the respective NI applications, or refrain from updating to Mac OS X 10.7.
Native Instruments has found no other compatibility issues under Mac OS X 10.7, but says that it plans to conduct further systematic tests once it has access to the final release version of the operating system.
Note: TRAKTOR and KORE are 32-bit applications only, and therefore not affected by this issue.
