Find my iPhone app used to be able to detect my laptop, but now it can't. Says it's "offline" but it's not. I have it on right now! Would appreciate any help to get it working again with all of my devices.
Pro, Mac OS X (10.6.8), iMovie version 9.0.4
Gosh, you can't even sign out of your iCloud account without agreeing to deleting calendars and reminders! I thought that if I signed out of my iCloud account on my MacBook, that will prevent a thief from signing in again and turning Find my Mac off.
I'm not sure what you're trying to accomplish by singing out. If you sign out, this will turn off Find My Mac too since the iCloud account will no longer be active on your Mac. It isn't possible to be signed out of your iCloud account and still have Find My Mac active on it.
Don't think you can. You could make it harder by making sure your user account requires a password, and that automatic login is turned off in System Preferences>Users & Groups. But a theif could still do a clean install of OS X, thereby erasing your settings.
