High Sierra last macOS to support 32 bit apps
With High Sierra now available I made the customary check to see what possible problems may result from installing it. What I found was a bit worrying. Not in respect of High Sierra itself, but the fact that the subsequent update is not going to support 32 bit apps. A quick check on how many 32 bit apps my Mac is running revealed a very long list, and they are not by any means all minor pieces of software. For example, Amazon Music, Audacity, BBC iPlayer, Kindle, Libre Office, MS Office 2011and many more, a lot of which I use regularly. Perhaps the respective developers will be producing updates before the fateful day, but I would imagine that rewriting 32 bit code into 64 bit code is no simple task.
As for MS Office 2011, I further discovered that MS are not going to support it on High Sierra, and in fact all support for this version will end on 10th October this year. With Microsoft limiting its basic Home and Student offering to one computer, replacing the copies on my Mac, my MacBook and my wife's machine would be very expensive. My existing Office 2011 came in a family pack with three licences. I may, therefore, initially only upgrade the copy on my Mac. My MacBook is still running El Capitan, being too old for Sierra, and fortunately my wife rarely uses Office.
Every so often Apple makes a move that renders a lot of legacy software, and sometimes hardware redundant. We are I fear approaching one such paradigm shift. The arrival of Snow Leopard cost me money and it seems that the post-High Sierra world will do likewise. But, on the other hand, this clean-out of arguably less efficient technology at least avoids the situation in which Microsoft finds itself, where the need to continue to support legacy programs has resulted in the Windows operating system containing far more code than it need do.
