Hey, so I installed DP1 when it first came out and am trying to update to DP2. The install has downloaded fully and asked to restart so I clicked yes. However it has stuck here and not gone any further. I have tried quitting and clicking 'Update' again and again but it isn't doing anything. I also have restarted, reset the SMC and PRAM (just because its easy ) but it hasn't changed. Anyone else having this issue? Oh and where it shows all the recently installed updates, there are many, many DP2s that say they have installed but haven't.. (see attachment) Please help!!
