Unable to shrink a partition in osx 10.10 Hi, I installed windows using bootcamp, but i made the mistake to make the bootcamp only 20gb, so i want to expand it. I found a way to do so, but firstly i need to shrink my other partition - Macintosh HD, why am I unable to do so? Thanks
Well, I have another solution; hope it would work fine. Backup Windows data (bootcamp) firstly. Use Bootcamp utility to delete the existing Windows partition. Once you delete it, recreate new Windows partition with Bootcamp a little larger as you desire. Then reinstall Windows.
