Mac Problem: Sierra/ High Sierra—Description and Options

  1. For Mac owners some serious problems exist beginning with Sierra (OS 10.12) and are still there in High Sierra (OS 10.13). GlazeMaster runs fine on Mac OS 10.11 (El Capitan) and older. I have been working for a couple weeks to solve these problems, but have not been successful so far. I cannot recommend you start using GlazeMaster if you are using or planning to upgrade tp Sierra or higher. For those already using GlazeMaster, parts of it are still useable in Sierra and High Sierra. That is explained in the next paragraph below. So far as I can tell, the free Windows copy should run normally without the problems described in 4 below up to and including Windows 10.
  2. The problems alluded to in the above paragraph are described here. As noted, these crept into the system beginning with Mac OS 10.12 (Sierra) and are still there in Mac OS 10.13 (High Sierra). When you start GlazeMaster you will probably be told that it cannot find the file Displays.USR which it needs. When you click OK you will be taken to a file finding dialogue box. Make sure you know where the GlazeMaster 3.02 folder is and select the Displays.USR file in that folder. The program will then complete the startup process. Your may have to do this every time you start the program. It is not a big deal once you do it the first time. The more serious problem is that you will not be able to add new recipes or materials. The program will simply crash. You still can access recipes and materials that were entered in earlier versions of the OS. You can even change a recipe composition and have GlazeMaster recalculate unity. You can print recipes. So all is not lost from your previous work. When you quit GlazeMaster you may also get a message that it quit unexpectedly. Ignore this. Sorry about this, but I have spent many hours trying to find and fix this problem and simply cannot. Maybe someone working with the original FileMaker files will be able to figure out how to fix it

If you already have Sierra or High Sierra installed on your Mac, here are some things you might do to get GlazeMaster running.

1. Reinstall El Capitan. Search for ways to do this. You will find several articles on the internet.

2. Find a friend who is still running El Capitan or earlier. Get permission to clone his boot drive to a portable or thumb drive using a program like Carbon Copy Cloner or Super Duper. Then when you want to use GlazeMaster reboot your machine from the cloned drive. I do this every time I upgrade so I can go back to the older OS easily.

3. Buy a Windows laptop (I know that’s going to the dark side) on Ebay, Craig's List, or a local computer store. One running Windows 7 can be had for $100 or less. Then install the Windows version on this computer. Move your Mac folder to the Windows computer and use the upgrade procedure (Main Menu) to move your recipes and materials. The Windows version can read the .USR files in the Mac folder.

4. Find that old Mac buried in your closet and see if it still runs. Use it for your Studio computer. Or buy an older Mac laptop. A MacBook running Leopard or Snow Leopard can be had for about $75 on eBay. I personally had one buried in my closet that I dug out. It is running GlazeMaster just fine on Max OS 10.5.8 (Leopard).

5. I will add other suggestions as people report success with them.

6. Hope that I can find this problem and fix it.
