After installing Yosemite, safari doesn't work any more.

I have the exact same issue, Safari worked at first after I got Yosemite, but now I can't launch the app at all. The icon just bounces once and stops. Help!

EDIT: I've also just noticed that Mail doesn't want to launch either. Great.

What happens when you try to use Safari?

If you can launch Safari, open the preferences window and change or delete the home page setting.

I used to have this problem but it fixed itself somehow.

Safari opened up with all my bookmarks but the pages did not load (blue loading bar gets stuck at around 20%). I tried links from emails with no success.

I noticed that I also got the spinning beachball when I tried to open the App Store app, instead I got the message saying I could not connect to the app store. I then tried the support page on the app store issue (OS X: "Cannot connect" or "Cannot connect to the App Store. An internet connection is required") and did the Invalid or incorrect Certificates steps.

After restarted my macbook, everything went back to normal. Not sure if it is at all related to your issues but it might be worth the try. Good luck.

I have the same problem, cannot open Safari!!!

Installed Yosemite, everything but safari works - well it worked the first time it was opened, but once closed it wouldn’t reopen, just bounces in the dock a few times - then nothing.

Only when logged in as “guest can I access safari.

I’ve deleted cache.db, went on a bug hunt, found no malwear fiddled with the proxies settings -tethered to an iPhone and router, tweeked startup items, delated extensions, disconnected peripherals, nada!

So did a reinstall of Yosemite and once again safari opened the first time, but when closed will not reopen for user.

Have trawled the internet (seems to be a lot of people complaining about similar issues), but I’ve run out of ideas on how to deal with this.

I may be wrong but I think if you check your Black Apple upper left and select Software Update I think there is a Safari update as well.

I have the same problem.

All native Apple apps do not open. Safari , messages, keynote, mail, or app store. cannot download and/or update any app or Yosemite to re install app store doesn't open

Any ideas?

I have the same problem ;(

i have similar problem...

After i upgraded to Yosemite...foe one day...all were working fine.

Suddenly , when i was trying to browse the day after..... my safari, apps store, black apple logo click are not working .

I have tried reboot in safe mood, but it still in this problem...

Why does Apple launch upgrade version.....but the loyal customer should receive another trouble?? I don't understand..........

Anyone can help ..since Apple is not give the solution?

I went to apple store today.

They did software and hardware test, but they could not find fix to the problem.

The rep told me to reinstall OSX by

turning on my macbook and pressing COMMAND + R ( since app store does not open either)

doing this will give option of reinstalling OSX.

will try once i get home,

Bummer!

I have the same thing. Pretty annoying as a payed content creator.. 😠

Exact same issue.

Works right after the upgrade, but after a relaunch loads of apps don't work, I think they are all Apple's app, FaceTime, AppStore, Mail, Safari...

Except Itunes sill works.

I'm thinking of downgrading back to Mavericks, much fewer issues at the beginning.

Hope Apple fixes this soon or I'm going back.

I have the same problem too, after upgrading last night went well until the next day I just realized that safari wont run, I tried restart, it run for a sec and then goes like i dont have internet connection.while i use firefox it run with no problem. it applies to my app store too. my itunes wont play some albums too, (the free demo U2 album), I cannot believe bug like this can go unnotices at the early launch of new OS. Apple please fix and update the problem....
