## MacOS 11.0 Big Sur
2 2
3 3
Apple has released MacOS 11.0 "Big Sur". This OS includes compatibilty for Apple's new 'Apple Silicon' ARM-based computers as well as numerous changes and security enhancements. Because this is a major update, we reccommend waiting to upgrade any system required for scientific data processing. MacOS 10.14 "Mojave" or 10.15 "Catalina" are currently supported by SBGrid.
+### Apple M1 Silicon
+ARM64 compatibility
+There won’t be any support for native ARM64 installation for a while. We are not aware of any SBGrid supported applications that are available for native execution on Apple M1 CPUs at this time. Access to new Apple hardware is still limited - we don't have an M1 mac yet.Compilation for M1 will likely require updated versions of GCC for some applications and their dependencies, which is also not currently available.
