I was told by FileMaker tech support that v12 doesn't seem to want to run on anything higher than 10.6.8 but i just noticed that it runs fine on OS 10.13.2. Are there any tricks a non-computer-savvy person can perform to make v12 work?
FIleMaker 12 is two years past end-of-life, and the knowledge base clearly states that it is not supported:
That being said, in some cases filemaker "can" work with newer operating systems; but there is no guarantee that it will work and you may encounter issues for which there are no resolutions for.
The best thing to do and the only option I recommend as a professional is to upgrade to a supported version of FileMaker per the documentation. This saves the client headaches and money later on as you try to hack or continually need to reinstall clients to nurse along old software.
If upgrading is a concern, then you should look into annual license agreements, where you will receive license keys for the newest version of filemaker as they are released.
