This is not at all related to PPC computers in any way, but thought it was worth mentioning. Erik(eyougren) has complained a lot-and with good reason-about how folder tags changed for the worse in 10.9. For the history of color in the Mac OS, a tagged folder has highlighted the entire folder name. I once stuck the drive out of my Quadra(68K and running System 7.5.5) into a DA running 10.4.11, and was quite pleasantly surprised to see that the tags were still completely readable under OS X. In any case, 10.9 changed tags from highlighting the entire folder/file to just putting a small colored dot next to them. If you're a heavy user of them, obviously this is a problem. I'm not a heavy user of tags, but do use them when I have one folder that I need to reference repeatedly-it makes that folder easier to find. In any case, I was working earlier this evening on resaving a bunch of word documents as PDFs(to combine into one document) and was pleasantly surprised to see that Word still keeps the full highlighting on tags. Of course, this is just one program. Acrobat Pro-as I'm sure you probably know-does use the dot rather than the full highlight and I'm guessing that Office 2016 will as well.
