Can't resize (FileVault) partition after Bootcamp removal I have a recent Mac with two partitions. The first one contains MacOS, and is encrypted with FileVault. The second one contained a Bootcamp Windows installation. Here is a screen shot:



I deleted the Bootcamp partition to reclaim space. Turns out: as a FileVault partition can't be resized, it can not grow to use the extra space.

What must I do to have one big partition again?
As @alan-shutko pointed out with a hyperlink, the only way to resize a encrypted partition is to disable encryption, (rebooting again,) then changing the size. It worked for me!

It's a lengthy process if you wait for it, but bearable if you let the decryption happen overnight.
