• I've got an old 27" iMac (2011 with DVD slot) that has the dreaded 'grey screen' ie: it won't start up. I've tried all the various fixes but can't get past this. I'm guessing it could be a graphics card or possibly the hard drive.
    Its been getting quite slow, even though there's nothing on it - most of my files are on Dropbox.
    I was thinking of taking to a local Mac reseller to diagnose what's wrong with it and if they have to take it apart to replace a faulty part, I wondered if it's worth asking them to swap the drive for an SSD setup instead.
    Any thoughts would be gratefully received.

  • SSD is a great idea! However if the failure is from graphic card or main board it will be expensive to solve. Check that first before investing on a SSD

  • The iMac seems to have fixed itself!? Turned it back on last night - firstly in recovery mode, but later it started up normally - first time in weeks!
    I've run as many tests as I can and they are coming back OK, so might go for the SSD upgrade - I've seen the tutorials online, but are there any recommendations out there?
