Apple has released its latest upgrades to its operating system (called Lion -- OS 10.7, Mountain Lion -- OS 10.8, Mavericks — OS 10.9, Yosemite — OS 10.10, El Capitan — OS 10.11). None of these support a translator program called Rosetta which bridged the change from PowerPC to Intel processors a few years ago. So what you ask?
GlazeMaster 2.3r3 and earlier versions need Rosetta to run. These versions will not run on Lion. Mountain Lion, Mavericks, Yosemite or El Capitan. If you plan to upgrade to one of these or buy a new Mac you will first need to upgrade to GlazeMaster 3. It is a free upgrade for previous purchasers. Transferring your recipes, recipe sets, and materials to the new version can be done provided you do it while you can still run version 2.3r3 (or earlier). Everything will transfer except photos which you might have imported. The process is described in a detailed pdf file that is included in the download.
In the meantime, what to do? Here are 2 options.
1. Wait to upgrade until you fully understand the consequences. There are lots of other programs that depend on Rosetta and some of them may not be upgradeable or will be expensive to upgrade. Examples are older versions of Quicken, Photoshop, FileMaker, or InDesign. You may find you have a number of other programs that will either need to be upgraded or replaced with something else. Here is how to find out.
a. Press down the Option key and select System Profiler on the Apple Menu.
b. Scroll down to Software/Applications and select it. Wait a while until the beach ball stops spinning.
c. Expand the resulting screen so you can see 'Kind'.
d. Click on the word 'Kind' so that column is alphabetized. You can then see applications that are listed as Classic, Intel, PowerPC, or Universal. Ones listed as PowerPC or Classic will not run on Lion or Mountain Lion.
2. If you want to upgrade and have a Mac that is not brand new (the brand new ones will not boot into Snow Leopard), keep a bootable external hard drive with your current (Snow Leopard or earlier) OS installed on it. This is easy to do and a good thing to do for lots of reasons--like when your main hard drive fails. To do it get a copy of Carbon Copy Cloner (free--donation requested) at http://www.bombich.com/ Use it to make a clone of your current drive before you upgrade. You can then boot into that drive by selecting it in System Preferences when you need to run older programs that won't run in Lion (or later). This is my personal choice regardless of the GlazeMaster issue. I have several other program that I have no need to upgrade and don't want to pay to do so.
