Disclaimer: Not a Mac user.
Allows installation of Windows alongside OS X & allows user to select between them at boot time.
Pros: Exposes hardware directly to Windows, meaning SW is more likely to run successfully (probably without RealView)
Cons: Switching between OSes requires reboot.
Allows installation of Windows inside OS X on a "virtual PC" (Software that translates Windows calls into OS X ones).
Pros: No need to reboot to use Windows programs
Cons: Virtual graphics card may have too low a spec to use Solidworks at all
Thanks for the reply, Ian. It seems like Parallels would be the better choice though it sounds like I may need to upgrade my graphics card. Not sure if I would want to expose my hardware to Windows. SW on the Mac will only be used for minor changes while I am traveling. The main work would be done on the Dell desktop I currently have.
By "expose hardware", I meant that Windows can use exactly what is installed in your Mac.
Bootcamp is supplied with OS X. Parallels costs money, but has a free trial version.
2014 iMac here running Mavericks / Parallels / Windows 7 / SW 2014 sp4 what you lose in solidWorks is the true view shading n such. Other than that I notice no real issues.
