My mid-2012 MBP (non-retina) is still humming along thanks to a few upgrades over the years (16GB of RAM, 1TB SSD), but now that I've skipped an entire form-factor cycle, it feels like it might finally be time for an upgrade this year. I was going to purchase one in the next week or two, but I'm curious if there's any merit to waiting for High Sierra to come out first. Usually with a new computer I manually migrate data to clear out the cruft, but years of working in IT has given me a cautious and superstitious approach to computers and it seems like moving data on an HFS+ disk to an APFS disk feels safer than HFS+ to HFS+ and then doing the in-place upgrade to APFS once High Sierra comes out. Perhaps it's just superstition, but part of me feels like upgrading a filesystem in-place may lend itself more to data becoming corrupt or files being lost. Am I crazy about this?
