In the app store where Yosemite is available for download, under “learn more” there are a number of comments by people who have had various problems. That’s what I was referring to. Based on these, I’m holding off upgrading to Yosemite until it seems more “trouble-free”. Any information you have would be appreciated.
I don't think I would be too worried. Beethovenfan.
The adoption of OS X.10 Yosemite is approaching 20% of Mac users which means 20 million users out of which 178 complained of problems so far to the OS X.10.3 upgrade. That is a remarkably small number of complaints compared to the already installed base. . . and indicative of individual hardware issues and loose nuts on the keyboard (i.e. user ignorance and/or learning issues) than anything than anything endemic in the OS or upgrade.
Many of the complaints I read seem to be of the "I don't know how to use Photo like i know how to use iPhoto" such as the one I read where the fellow was complaining about no geotagging or keyword tagging. . . both are present in Photo.
I did a Google search for OS X.10 Yosemite problems and it was remarkably free of issues complaints. To me, it looks as if Yosemite is one of the solider upgrades Apple has ever released.
