We’ve all heard that Windows machines need a wipe/reinstall every couple years. (I don’t know if that’s actually true, or just anecdotal. I rarely have the same machine more than a year or two, so it’s never come up in my personal experience.) Is there any parallel belief here, that MacOS X installs need to be refreshed periodically? More important, is there any evidence either way?
My “laptop” install has been through three pieces of hardware (2008 MacBook, to a MB Pro, now on an Air), and six point versions of MacOS X (10.5 to 10.10). I’ve not noticed any real issues, but it’s possible that the ever-improving performance of the hardware (faster CPUs, more RAM, moving to SSD storage) has masked any software issues.

The existing desktop had started life in 2008 as 10.5, and had had lots of "stuff" installed and removed over the years, including some tools that had overly-intimate knowledge of MacOS X. Don't get me started on all the crap AV stuff I tested. Some items I had tested over the years had installers that were not very good at cleaning up. It had also been incrementally upgraded from 10.5 through 10.8 I did a complete new install of 10.8 onto the new drive, and then used the Apple migration tool(s) to only bring over data files. I also could have used a time machine backup. Applications I re-installed from scratch. This was probably a tiny bit more time consuming than the disk duplication paths, but to be honest, I installed the SSD at about 0800 and was completely up and running with 90% of what I wanted by 1100. I did install a few more apps over the next few days. This completely avoids all the dd block size, TRIM, SSD black magic, etc issues.
