Issue I463 [80,mostlyresolved] Formal support for Intel-based Mac OS X running Windows version of SIMION Running the Windows version of SIMION 8.0 on Intel-based Mac OS X is now formally supported via the following three methods. (Note: older PowerPC-based OS 9 Macs will generally not work well or at all.) These methods have been tested by SIS and work quite well. * CrossOver Mac (Windows compatibility layer) - see Issue I464 [ http://www.codeweavers.com/products/cxmac/ ] * VMWare Fusion (virtualization) - see Issue I466 [ http://www.vmware.com/products/fusion/ ] * Parallels (virtualization) - see Issue I465 [ http://www.parallels.com/en/products/desktop/ ] Other less-formally supported methods may work as well, particularly virtualization software like VMWare/Parallels. See also http://www.simion.com/info/Mac_OS . WINDOWS LICENSING: Using CrossOver DOES NOT require a Windows license. Using virtualization software like Parallels and VMWare VMWare DOES require you have and install a licensed copy of Windows into the virtual machine (Windows is purchased separately). The CrossOver method can be more cost effective. PERFORMANCE: Both CrossOver and virtualization (VMWare and Parallels) run largely at native speeds, though CrossOver particle flying seem about half speed (see Issue I464). MEMORY USAGE: SIMION under both Parallels, VMWare, and CrossOver has a memory limit of roughly 1.2 GB, of 130 million points, or higher per PA (when the "--reserved-memory" option is used). This may depend on guest OS and virtual machine memory allocation settings (which were not fully explored during testing). EXCEL [CONDITIONALY SUPPORTED]: Controlling Excel from SIMION is only supported via virtualization (i.e. Parallels/VMWare not CrossOver) and only if Excel is a Windows version installed on the virtual machine. (See Issue I464 on this for details.) SIMION 8.0.5 may freeze when using CrossOver versions prior to 7.10. Either upgrade CrossOver to >= 7.10 or downgrade SIMION to <= 8.0.4. SUMMARY: SIMION 8.0 runs well on all the above options. There is some slowdown in particle flying under CrossOver. If you want integration with (Windows) Excel you should use virtualization (VMWare or Parallels), but if you want better integration with OS X applications you might want to instead use CrossOver since SIMION will then run more like an OS X application. SIMION 7.0 works ok on all the above but seemed to run most smoothly under Parallels (SIMION 7.0 does some tricky things with the mouse that cause some non-critical mouse behavior issus under CrossOver and VMWare).
