Hi all My late 27" Late 2013 imac (i5 - 8gb ram) - is insanely slow - I think it's the 1gb fusion drive: Esp. things like opening mails, or just having it open the emoj-window takes ages - so no smiies Anyways, I'm considering my options here: 1) I could throw in more ram, which is not "that" expensive, and is a very easy upgrade: but still cost money if it does not do that much for the machine? Usually I have spotify + facebook + an extra website + sublime text + trasmit(ftp) + slack + mail + photoshop + dropbox + a few more light programs open at a time, and that's usually that. 2) I could do something software wise with the fusion drive, try to optimise it somehow. Perhaps split it open into ssd and harddive ... TRIM it or something ... Look for spyware and stuff ... Will probably reinstall when high sierra comes out and is stable enough... 3) I could buy an external ssd, and try if I could move the OS and filesystem over onto it - and use the fusion drive for all my data files. I would need the best guide to do so most optimal. but I take it that this would be easy for me to do. And not all that expensive either. I don't know how much speed I can gain by this / how much slower it would be vs: 4) I could cut it open, and replace the fusion drive with an ssd and I'm actually considering this. Have seen some guides and think I could pull it off, and would be willing to take the risk (I would not risk losing data - just the machine). But there has to be a speed advantage in it over 3 for me to do so. It might be an extra thing taken down with two punches, since the hinge is broken (not at problem for me), so if I open it up anyway, I could consider replacing the hinge as well ... I am tech savy ... but have no experience doing any of the above with a mac - so I'm really hoping someone can give me some feedback that will make me take the right decisions to make this mac live another few years. Thnx guys.
