Hi guys, I'm finally going to bite the bullet and instal High Sierra on my MacBook Pro (Retina, 13-inch, Late 2013). I need the latest Xcode and cannot see that it is possible on Sierra so I'm forced to upgrade. My specs are below. Processor 2.8 GHz Intel Core i7 Memory 8 GB 1600 MHz DDR3 Graphics Intel Iris 1536 MB I'm wondering, with just 178 GB of 1 TB being available on my SSD, is it worth me completely clearing my laptop and doing a brand new instal and then moving everything back over and reinstalling everything. Or will this make little difference to the installation and performance after the upgrade? I think I have about 260GB of documents and 140GB iTunes. Anything else you might need to give me a recommendation, just ask. Thank you.
