So I’ve gone and done – I’ve updated to Yosemite.  So far so good the only problem I’ve encountered was with the Blurb Book program but I just had to down load the Javascript update (not sure why this wasn’t included in the upgrade) and everything seems very much as normal.  The interface is very clean and clear and the icons appear to be so much brighter.

Talking of brighter I had a chance to have a look at the new iMacs today with the much vaunted Retina displays and I have to say I was underwhelmed.  Whilst the images did look very impressive I did notice that the computer I was using had a bit of a problem refreshing properly so there was a noticeable lag in the image becoming pin sharp.  It wasn’t off putting but it was clearly there which makes you wonder why that is?  The most obvious answer is the the video card/chip/support isn’t unto the task of supporting the high pixel count of the screen.  If this is the case then it really does undermine the whole point of having a super sharp screen.

Apart from this it was just another iMac – which is actually a compliment.
