Hi all, I think this is the best place for this question, it's a real head scratcher so I'm hoping someone can help. Here's my problem: Until recently I used a MacBook Pro for work. This was great as if I needed/wanted to work from home I could turn it on and carry on where I left off. Last week however, my trusty 2011 17" MacBook Pro finally started getting the graphics card issue, and after some attempts to fix, it's not reliable enough to use any more. So at work I'm now using an iMac, which works great but obviously means I can no longer work from home. A new MacBook is not an option. Essentially what I want to be able to do is plugin an external drive, work all day, then take that drive home with me so I can carry on if I need to. I initially took my internal SSD out my MacBook Pro to use as a boot drive, but since my own personal MacBook Pro is from 2009 and can't run Sierra, I was unable to boot using my 2011 MacBook Pro's SSD. Bottom line: I want to be able to work from where I left off, have all my apps, settings etc from my iMac at work stored on an SSD that I can boot from anywhere. Here are some of my initial thoughts, but any suggests are absolutely welcome! - Time Machine - do I backup using Time Machine and take this home with me? In order to use it however I am guessing I will need to restore my own personal MacBook Pro losing all my files. Plus would this even work with the 2011/2009 difference? I'm guessing the answer is no... - Carbon Copy - Although I couldn't boot from the SSD from my 2011 MacBook Pro, I could still see all the files. Although not great it did mean I would be able to do somewhat most of my work. Could this be a solution? Only thing is I don't want to have to wait for it to complete at the end of the day, just unplug and go... - I splash out myself and buy a new/newer MacBook Pro for myself that would be capable of booting from an external drive running Sierra (£££!) Any other options absolutely welcome!
