Find My iPhone Showing Up Online, No Location Available

I am having this exact same problem and it is driving me crazy. Location services and find my iPhone works for my iPhone, my iPad, but NOT my MacBook Pro.

I'm running Yosemite 10.10.1, and I can't get it to discover my location in FMIP and I also cannot automatically set the time zone in Date and Time (although I manually set it to my correct time zone). None of the applications that are supposed to be able to use location services on my Mac (Maps, Safari, Weather, etc.) can actually find my location when I use them on my Mac. No problem for my iPhone and iPad. All of these devices are running on the same WiFi network at my house, so I know that's not the issue.

There is some kind of BUG in OS X, and after researching this as much as possible on the Internet, it has been problem for quite some time.

Dear Apple Computers -- Where is the fix? This is really annoying.

HI

i having SAME problem :

location servics enables (nothing in list)(no app in list which accesses location),

icloud "find my mac" enabled,

and WHEN I TRY TO FIND MY MACBOOK ON icloud or "find my iphone app" on iphone.

it says:

"ONLINE,LOCATION UNAVAILABLE"

and one more thing, when i set "time & date" to "set automactic according to my location"

then the result is "unable to determine location at this time."

CAN ANYONE TELL, HOW TO MAKE LOCATIONS ACCESSED? IS IT WIFI SETTINGS? OR IS IT OTHER SETTINGS BEYOND MAC .???

I had the same problem. Make sure the Date & Time settings on BOTH your iPhone and iCloud are set correctly. My iPhone settings were correct, but my iCloud Settings were set to the wrong time zone. Once I fixed the iCloud Settings to the correct timezone, the Find My Phone service synced immediately and started working correctly to find my phone.
