My applemacbook pro has recently changed itself from OS Lion to Yosemite. Flash player then stopped working. I have tried every which way to install Flashplayer which has always worked well before. I have uninstalled it and reinstalled it several times. It tells me it has been installed but when I look I can only see 'Shockwave Flash 17.0 r0 — from file “Flash Player.plugin”' which seems to give me Application future splash and application shockwave splash. I don't see application flash player. I can't open files needing flash without the 'get adobe icon' showing. Plugins are enabled. I've been through the forums and am now at wits end. Please if I haven't done something can you tell me simply, in easy steps, not assuming I might understand contractions of in-club computer language!! Maybe the problem isn't mine at all??? Maybe there's a conflict with Yosemite? If I look at the install arrow at the top of the screen it has been highlighted. If I click on it it tells me I have Adobe Flash Player to install and then the circle starts again. I click on it and try to reinstall once again! Many thanks to anyone who can help me.
