Two days ago my Macair gave grey screen and gearwheel on startup and refused to boot, finally after multiple restart attempts gave it a cmd - R on startup and disk was a mass of errors, repair disk finally fixed these after 4 solid attempts but there were some strange issues after it all started up again, no sound in some programs or on the keyboard and wifi dropdown showed menus in programming script. Took it into the apple people in Dubai and they checked it out in detail and decided it needed a system install which I agreed, 99% into the install it stopped and showed errors in install. Restart showed the SSD as being 33kb and that was it, gone, fried.. Really not happy as this is my first mac and I love it, especially portability and ease of use and even like osx after a lifetime of Windows so am in the process of getting it fixed so will see how we go, I hope this is a one off as seeing as how the machine is so well made a robust I had hoped internals would be similar quality, I know they are the same as we use in PC's but even so........ One thing I did, as I also use a windows laptop for work, was change my way of working slightly away from reliance on backups so that I keep all files on Dropbox and all emails on google or other cloud servers and can therefore access anything anytime on either machine or the Android phone. This means I can continue on without worrying on lost info, I also still do backups 3 times a week so have a 1 day old time machine backup waiting for the new disk, again lucky. Anyway just wanted to rant a little, still love the mac idea but am now a little more wary of thinking they are that much better than PC's and the morale of the story, do not rely on only one machine for file storage!
