There's huge variation in compatibility across the OS 10x series, unfortunately. There were at least three system releases that they should have numbered OS 11, 12, etc. Particularly big leaps from 10.4 to 10.5, 10.5 to 10.6. My desktop computer runs 10.5.8. It still runs Eudora (yay!) but has no competent browser (I have to use Firefox for Youtube or anything with advanced Flash, which doesn't like this version of Chrome--and Chrome for Facebook, which won't play at all nicely with this version of Firefox. The desktop computer will not run the current MS Office, and while I can open Office 2011 Word and Excel files, it will not open a recent Powerpoint using SmartArt (such as what I presented for your group at TEDx Shelburne Falls). And more and more websites AND groupware/webinar platforms (GoToMeeting--Nyet; Google Hangouts--depends on its mood) simply won't work on this configuration. Sigh! My stepfather's computer is just a few months older than mine, but won't run anything past 10.4. It's almost like running system 9. The laptop, only a year and a half old vs. about 5 years for the desktop, started at OS 10.6 and is now running 10.8.9. To my utter dismay, it never supported Eudora and won't run some other old stuff too. I'd suggest asking software manufacturers for compatibility assurance before venturing forth. It's likely that you can't reverse it. > ** Be sure to fill out the survey/skills inventory in the member's area. > ** If you did, we all thank you. > > >Yes - I want to upgrade not downgrade.
