OsiriX System requirements
- MacOS X 10.7 or higher.
- Intel processor
For best performance:
- 6 GB of RAM if you plan to open more than 800 images (CT & MRI, PET-CT).
- 8 GB of RAM for more than 1500 images (multi-slice CT & PET-CT) with OsiriX-64 bit extension.
- 12 GB of RAM for more than 3000 images (cardiac or functional imaging) with OsiriX-64 bit extension.
As long as you installed OsiriX with a 32 bit Intel Mac and are using it with the same Mac I cannot see why you should have any problems. If the software is imprudently written it may only want to work in the normal applications folder. If this is so it can probably be cured with a symbolic link - see man link.
