I’d like to install Unity 3 as a full install on my mac to test it out, without it overwriting my copy of Unity Pro 2.6. Is this possible? It works on my Windows machine, but I can’t figure out a good way to accomplish it on the Mac side.
Thanks!

During the install click change location… Choose a new place to install.
I never tried this, but it should work…
Unfortunately that won’t work unless you have a 2nd hard drive to install it on. What I do is that I rename my old Unity application folder to “Unity 2.6.1” -before- I install the new version. Otherwise it will install it on top of it (thus deleting the old version). Then I have two apps in two separate folders, “Unity 2.6.1” and “Unity” (which has 3.0 in it). I then rename the “Unity” folder to “Unity 3.0” just to help me remember. HTH
Installed in parallel fine for me on MBP with a single hard drive. I just renamed the Unity folder to Unity 2.6 before I installed Unity 3.
I may have also temporarily moved the Unity 2.6 folder to the desktop while I installed it; can’t quite remember.
same here, working both versions of unity free to make tests and port my stuff
renamed unity → unity261
installed unity 3 THEN renamed unity → unity30
as for the project folders:
documents/unity projects/261/… my projects with 261
documents/unity projects/30/… my projects with 30
what happens to the builds? 2.6.1 builds its projects and 3.0 its own separately, as being 2 different packages? my answer checking the build properties is YES, each version builds its own projects. 
Great! Thanks
