File compatibility after High Sierra Upgrade
I want to upgrade my iMac ( Late 2014, 5K, i5, fusion drive, Sierra 10.12.6) and my MacBook Air ( Mid 2013, 13 inch, i5, all flash drive, Sierra 10.12.6) to High Sierra. I also use iCloud to share desktop and Documents folder files. I also use Dropbox for a separate set of files.
What must I do to ensure my files are compatible across both computers after the install?
Thank you for your help with this.
Mac OS X (10.7.2)
