I have 3 partitions on my hard drive right now, and none of them are able to be resized (the apply button is greyed out when trying to partition).

I also feel like my drives are messed up in some way because I tried to get Apple support to help with resizing, and they just said they don't know what's going on, and I need to do a full reset. However, I don't want to reset the Bootcamp partition as I don't have access to/can't find the license anymore to reinstall Microsoft Office, which is mainly what I use Bootcamp for.

Can anyone help me figure out how to resize my OS X Base System or Bootcamp partitions, so that I can have more space on my MacOS Sierra partition?

Here are some details.

Disk Utility can't resize Windows NTFS partitions. You can do advanced container/partitions editing in a GUI with a third party application:

Paragon Hard Disk Manager

It has fully functional 10 day trial period.

  • Do you know what's going on with os x base system? Apparently, it's not supposed to exist be viewable? – jtanman May 2 at 20:19
  • I don't know what to do about OS X Base System. A better approach would be if you start from scratch. I know it's a lot of work, but with good planning you could have a better use of the storage. About that MS Office 2013/2016 License key - some websites state that you can't recover it, because only the 5 last characters are stored on your computer. However, other suggest that you can extract these last 5 characters with a VBScript code, and then matched with the rest of the key, stored in your Microsoft account page. It that's working, you can safely do a clean install. – modlin May 3 at 9:19
