I'll go as far as saying that my copy of 8.5v2 opens in Sierra. Your mileage may vary.
I'd guess that you'll run into issues. When you say "macros" are you talking about scripts or something like AppleScript? Look at the knowledge base articles on the various versions of Mac OS X to see what FileMaker has to say on the issues. Common things may be printing, PDF creation, plugin compatibility, Java issues, on-screen rendering, etc.
If you really have to keep 8.5 around, I'd suggest installing Parallels or VMWare and run 10.6.x in a virtual environment.
thank you for your quick reply ! Yes I did mean scripts. Did you use 8.5 also with El Capitan and Mavericks before moving to Sierra ? In your experience which one potentially gives "less" problems ?
We do not use the files every day and can accept some issues like printing problems and pdf creation.
Thank you !
No worries. I can't say that I used FM 8.5 with either El Capitan, Mavericks or Sierra for any serious work. A few times if a client came to me with an old file that needed to be upgraded. These days a couple clients are still running FM 11 but nothing earlier any more.
I need to update my MacBook Pro from MacOs 10.6.8 to a more recent system but I need to keep Filemaker pro 8.5v1 - I tried to import some of my old files in filemaker 14 but all macros do not work corretly.
Thank you !
certainly not officially: FileMaker Pro operating system requirements - all versions | FileMaker
So do expect things to not work. Assuming that it won't break is dangerous...
Can you give an example of what a 11 year old "macro" not working any more looks like ?
What is a 'macro'? A FileMaker script or a third-party-utility macro?
We migrated quite a lot of old .fp5 files to FM 13/14/15 and we also converted a lot .fp7 files to the latest versions - no problems so far...
