Hi Alan,
Thanks for the manual update which I could not find on the website. However, the website does offer the following download for the 3.0.7 update:
pIllusion_OSX_307_update.pkg.zip with the instructions, ‘unzip, the double-click the pkg file to start the installer’.
This is exactly what I did – I am using OSX 10.5.4.
Regards,
Nigel
