Dominic. Gray posted a question in OS X Mavericks 10.9Hi, I have installed Nireshs Mavericks 10.9 today. Everything seems to be working fine except iCloud is not working, as when I go into system preferences I cannot log in. I just get an error message that tells me to try again later. I did try and update Mavericks to. 10.9.3 but this did not work and my computer went into a reboot loop, so I have installed mavericks again, and iCloud is still not working. I have tried the fix on Nireshs website but this did not work. Any help would be greatly appreciated.
