I followed all of these steps recently in order to split my drive up to where BootCamp could work with it (needs to be 2.2 TB or less). First of all, I started off trying to split the 3T into two 1.5 partitions. That should have left enough for Bootcamp to use disk0s4. Instead, Disk Utility gave me one 800G and one 2.2T partitions! AND, there was no option to resize. So, I followed Apple's How to's to resize the first partition (necessary, because 800G left me with only 90G free space!), which was to remove the second partition. I did, and now I can neither resize the old partition or add the second one back. Has anyone run into issues with the new 3T drives?

I have done this more than one on more than one Mac, so I strongly disagree. I'm pretty sure this is the topic of this article. Huh?

Always keep a backup, even if you don't plan to change anything about the partitions. You just plain need a backup. If you remove the Windows partition, you can add the available space to the Mac OS partition, and then "Apply". Removing any partition removes all files on that partition. DUH! Sorry to say the obvious, but someone may need to know. BTW, you must use Boot Camp to create any Windows partition on a Mac. Boot Camp creates a hybrid MBR partition on a GPT scheme drive.

Just remember to back up your Mac beforehand just in case something goes wrong, which there is always a chance of when editing file systems and partitions.

Some time ago I did two partitions on my Hard Disk, One called Macintosh HD with 435,00 GB long and other One called Windows 7 with 203,00 GB long, it was planned to install Windows 7 on the second partition but i´d definitely not since I purchased a laptop with Windows 7 on it. So now I want to delete the Windows 7 partition and enlarge the main partition so that I just have one partition of 638,00 GB long. the question is ¿the process of enlarge the main partition from 435,00 GB till 638,00 GB would end up on a lost of main partition data? Thank you very much in advance. Hi, I got a question as simply as it gets about Disk utility.

I tried out of curiosity and it works perfectly fine. If we have multiple partition on a disk (internal/external), we need to choose the main disk from the Disk Utility by clicking on the disk and not on the partition and select tab and it works beautifully. I did this on my boot volume (system partition) while running applications without any issue I could partition. But I see that this is not helpful for my situation as this doesn't let one to grow the partition. i.e. say if one has 100 gb x 3 partitions, we can't resize and increase the size like, say make one partion 50 gb and use the 50 gb to make the other partition 150gb. But you can free up 50gb and create a new partition to make it 2x50gb and 2x100gb. Was looking for some partitioning information and stumbled across this posting.

Any application cannot be applied to resize the boot volume of the current system. It must be attached as an external hard drive to resize the boot volume. Well , a few days ago I have tried the Stellar Partition manager successfully. Yes thats right. Any application cannot be applied to resize the boot volume of the current system.
