iMac failing to shut down
Hi all, I have a late 2013 iMac, 27". Recently, it's been starting to hang-up almost every other time I shut down. It basically always involves me having to shut it down by holding the power button down. It then takes around 5 mins for it to fully boot up, but seems to run fine once that's happened.
The computer is relatively new, and I would say that I've installed enough rubbish on it for it to keep getting bogged down.
There's couple of other issues plaguing it, such as the internet constantly cutting out (either losing connection with the router, or simply not loading anything). The fusion drive (1.12GB) also seems to be split in two since the upgrade to Yosemite.
It's starting to feel a bit poorly!
Any help is greatly appreciated.
