Mac Problem: Sierra/ High Sierra—Description and Options

  1.  I have just released GlazeMaster 3.03 for Macs which runs on Sierra, High Sierra, Mojave and Catalina.  You will have to install version 3.03 (which is free) and do some work to transfer your recipes to the new version. The rest of the parapraghs on this page just describe the problem and how it evolved in a somewhat disorganized way.
  2. For Mac owners some serious problems exist with version 3.02 beginning with Sierra (OS 10.12) and are still there in High Sierra (OS 10.13). GlazeMaster 3.02 runs fine on Mac OS 10.11 (El Capitan) and older. I have now found the problem and have released a new version 3.03 for Mac owners. I cannot recommend you start using GlazeMaster 3.02 if you are using or planning to upgrade tp Sierra or higher. For those already using GlazeMaster 3.02, 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 of GlazeMaster 3.02 should run normally without the problems described up to and including Windows 10. No version 3.03 has been released for Windows and I do not anticipate doing so.
  3. 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 fixing this problem. 

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

1. Download and instal GlazeMaster 3.03. If you have a small number of recipes it may be simplest to just reenter them. If you have a large number of recipes, there is a pdf file in the download package that tells you how to transfer your recipes and materials to the new version.

2. If you want to stay with 3.02 reinstall El Capitan. Search for ways to do this. You will find several articles on the internet.

3. 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.

4. 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 that 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.

5. 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).

7. A little good news at last. The source of the problem is the Mac OS Sierra and High Sierra OSs, apparently not my coding. FileMaker versions (in which GlazeMaster was developed) up to and including FM 14 are not compatible with these OSs. This has also affected lots of other programs like Photoshop Elements and other Adobe programs. I have now upgraded FileMaker to version 17 and converted my files to it. On a very short check it seems to run just fine.
