So the story kinda goes like this, time to upgrade a client’s FileMaker 10 Server to FileMaker 13 Server. Simple enough.

Until… The hardware meets exactly the minimum requirements, slow internet, remote installation. The vendor who maintains the hardware upgraded the computer to Yosemite first before the upgrade to FileMaker Server 13. And it’s Saturday am, less than one coffee down. (Coffee is key to all things).

After extensive searching and digging for the FileMaker Server 10 installer on an attached drive… I moved it to the desktop and ran it and blank screen after a few of the questions for setup. It does not run in Yosemite.

The previous server must be uninstalled before we can install the new one. After a bit of all trial followed by repeated error, I tried the not so obvious. I used the FileMaker Server 13 installer and try uninstall.  It worked, with one caveat.  When I tried to run the installer, it ran then produced an error that it could not create the fmserver user. It already existed and needs to be removed first. You can remove it by using terminal and then installing it again.

So if you are upgrading to FileMaker 13 Server, at least going back to FileMaker Server 10 follow these quick steps.

  1. Use FileMaker 13 Server Installer app to uninstall pervious version of server.
  2. Open terminal and enter: sudo dscl . delete /Users/fmserver
  3. Run Repair permissions from Utilities/Disk Utility, until there are no errors, I make this a habit with any installation.
  4. Install FileMaker Server 13 and Deploy.

Hope this saves you some time with Upgrading to FileMaker 13 Server Yosemite.
