I delayed downloading and installing Yosemite as in late 2014 on the forums here it had problems to work with safari, at least for some people. Does anyone who Had this problem know if it has been resolved by Apple?
Loading a webpage and the progress bar stop at around 15% position...... forever.
Micro freeze the whole computer (except mouse pointer) for every seconds. (This is 100% reproducible on some webpages)
Sometimes start up in a second, but sometimes takes 30s.
I basically only use Safari since 10.5 (Leopard), and it works very well until 10.9.5. But now, I must give it up until they fix it.
Since all modern browser including Safari use GPU to accelerate, and there are few other 7950 users have exactly the same problem as mine. So, it seems that graphic card driver plays an important position on how Safari works. For me and some others, it's totally unusable now, but for some others, it works flawlessly. IMO, it's a kinda of hit or miss, not good enough for a daily use computer's OS.
Never had a problem, myself. Been using Yosemite since it was out on 4 Macs, Safari as primary, although others available. Usually something like that occurs when Safari has incompatible or otherwise undesirable extensions or adware like Genieo, MplayerX or MacKeeper, etc. So, although you might find it by searching, it's not what I would consider a 'common' problem.
