It seems every time a major new version of OSX is released there is a tsunami of posts from Mac users experiencing some kind of problem or crisis, as is currently happening with Mavericks. This thread invites your review of a proposed solution to this problem. PROBLEM: It would be nice to think that Apple could release OSX upgrades that worked perfectly on everybody's Mac, but this is likely unrealistic given the infinite number of different software/hardware situations that millions of Mac users are using. So let's take it a given that any new version of any operating system from any vendor will likely generate problems for some users. The point of this thread is to try to avoid as many of those problems as possible. ANALYSIS: Experienced users already know of a solution, install the new OS on a second drive or partition and test it there before updating their existing version of OSX with the new version. It seems the problem is that less experienced users don't know to do this, as they are following instructions from Apple to upgrade their existing OSX directly. This works fine for some, while others (many others) are left with a Mac with all kinds of problems. SOLUTION: A solution may be for Apple to educate users on how to test and install a new version of OSX safely. This can be accomplished by putting a prominent link such as LEARN HOW TO UPGRADE SAFELY on the sales and download pages, and in the installer. This would help users by teaching them how to safely test a new version of OSX to see if it will work for them, BEFORE they upgrade their existing setup. This would help Apple by reducing the damage to their brand which is generated by all the negative word of mouth which arises from those whose upgrade goes wrong. QUESTION: Why in your opinion is Apple not educating users on how to upgrade OSX safely? Wouldn't it be in their interest to do so?? Thanks for any comments. If possible, let's please try to keep the thread on the specific subject of constructive suggestions for how to prevent OSX upgrade calamities.
