It is over two years since I moved to the iMac and I still can’t get my head around their OS naming system – I much prefer the v10.9 et al than these pointless names.  It gets even worse when we come to updates which become 10.9.x etc.  Anyway besides this nonsense I have to wonder whether to update to Yosemite?  A friend of mine and long time power user of Mac’s says that you should give it a few weeks so that they can iron out the bugs.  This always makes me smile as Apple are developing within a closed system when compared to Windows and yet they still have bugs and faults.  I think I’ll sleep on it.
