I have an iMac 27" (Late 2009) which cannot upgrade past macOS High Sierra (10.13.6). The latest PD version supported for this OS is PD17.
If I purchase an upgrade to PD18, am I also able to install PD17 on my machine. Are older versions included with the new license, or am I stuck with PD15 going forward?
Thanks.
