I couldn't partition my hard drive because FileVault was turned on. I then started decrypting, but it got stuck on 90%. After 4 days at 90%, I can still access my device, but it's laggy and frustrating.
What is the solution to make it continue or at least to revert back without wiping my drive?
sudo fdesetup disable and
force restart, still, nothing is working.
I am using High Sierra MacBook Pro mid-2012.
