fixed : “Your browser is not supported” error in Safari on iCloud.com

Question :

I have OSX 10.8 Mountain Lion with Safari 6, but when I try to log in on iCloud.com, I get a message saying “Your browser is not supported. To use iCloud, we recommend using the latest version of Safari, Firefox, or Internet Explorer.”

The error on iCloud.com is the worst, but I also get reminders on other sites like Facebook and ANWB.nl that my browser isn’t recent enough, and I should update…

I can’t upgrade as I am already on the latest version of Safari.

I’ve tried switching the User Agent under the Develop chapter in Safari’s menu bar, but whatever I try, when I restart Safari, it automatically defaults back to a custom User Agent string that reads :

Mozilla/4.0 (compatible- MSIE 6.0- Windows NT 5.1- SV1- .NET CLR 1.1.4322

What can I do ? this is getting on my nerves…

Answer :

the solution is rather straight forward : delete all plist-files associated with Safari manually

here’s how to do so :

– in the Finder, in the upper menu bar go to “Go”

– then “Go to folder…”

– in the popup window type “~/library/preferences”

(that’s how you get into the hidden Library-folder)

– then drag these files to the Desktop (you might not have all of them on you Mac) :

com.apple.Safari.plist

com.apple.Safari.plist.ByIRcYZ

com.apple.Safari.plist.lockfile

com.apple.Safari.plist.RRS.plist

com.apple.Safari.plist.RSS.plist.lockfile

– then restart Safari and check if everything works as you would like it to

– if so, drag those .plist-files you just moved to the Desktop to the Trash

…that’s it

FYI : theoretically you could also have replaced the custom User Agent string by the proper one for Safari 6 :

Mozilla/5.0 (iPad; CPU OS 6_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10A5355d Safari/8536.25

…too bad that your Safari will probably not be able to save that though, so you’ll still have to follow the directions outlined above…
