- Ext2 partitions need periodic file system integrity checking, and this can cause delays during booting when the partition is large. For multi-user systems or systems with lots of disk space, it's best to put /var, /tmp, and /home each on their own partitions separate from the / partition.
- The Disk Utility’s Partitioning controls enable you to partition your MacBook’s disk. If you find yourself needing another volume on a disk — or if you need to resize the total space on existing volumes on a disk — click the Partition tab within Disk Utility to display the controls.
- If you are looking to format a disk that will be shared with Windows users, the MBR scheme and MS-DOS (FAT) are the best choices. For drives used with Intel-based Macs only, the GUID Partition Map should the option to go for. If you don't see the partition map scheme option, it is likely because Disk Utility doesn't list all volumes.

You may want to divide a drive into more than one partition. When you do this, each partition is a volume, and each volume shows up as a separate drive on your Mac.
Partitioning a disk on a Mac is an effective way to organize your data into different categories. However, the main concern is that most external hard drives and USB keys come formatted for Windows, which is primarily for PCs. By default, a Mac runs a different file system, so it may bring issues while partitioning your disk on Disk Utility.
Hard drive partitioning is a common issue discussed in many tech forums. In a thread on Apple’s support forum, users complain that their Mac Disk Utility partition grayed-out while trying to partition their external hard drives.
Probably, you just bought your external hard drive and are eager to use it on your Mac. But somehow, you cannot access the Mac Disk Utility partition, so you can’t write data to the drive.

Fear not, we have a solution to this problem. In this post, we will guide you through a step-by-step process on how to restore a grayed-out Disk Utility partition. Many Apple users who have faced Partition grayed out in Mac issues eventually partitioned their external hard drives with the help of these fixes.
Why Partition Grayed Out in Mac (Plus Solution)
Problem 1: Sometimes, you cannot access the Mac Disk Utility partition because your hard drive doesn’t have sufficient space.
Solution: If you want to go ahead with the partitioning task, you need to create more space on your hard drive. In other words, you have to erase the data on your drive to create additional space. You can then format your hard drive using GUID Partition Table. After that, go ahead with your partitioning plans.
Important Note: Before formatting your hard drive, back up your most important files. Needless to say, the process will get rid of all the data on the disk, so you risk losing your files for good.
Problem 2: As mentioned earlier, external drives are usually not compatible with macOS, which may bring issues when you want to partition. In most cases, users choose the wrong partitioning option, and as a result, the Partition option in Disk Utility remains grayed out.
Solution: The right way you should follow when selecting a partition option is to choose the drive name within the list provided under Internal or External (depending on the device you want to partition). Your hard drive will be available on the left side of the Disk Utility pane.
How to Restore Grayed Out Disk Utility Partition: Format Your Hard Drive to Work with Mac
To format your external disk to be compatible with macOS, connect your hard drive to the Mac and follow these steps:
- Open Disk Utility by going to Applications, then select Utilities > Disk Utility.
- Choose the drive name within the list provided under ‘External’. If your hard drive is connected, it will show in the left panel of the Disk Utility. Highlight the disk and click the Erase button in the top toolbar.
- Wait for a window asking you to select the file system you want to use to format your external drive to pop up. For your case, you will select ‘Mac OS Extended (Journaled)’. But if you have plans to use your disk for both PC and Mac, then a better option is ‘ExFAT’. You can also rename your hard disk here to your desired name.
- Wait for the formatting process to complete. The process usually takes less than a minute, but it depends on the size of your hard disk.
- When done, confirm if the formatting was successful by right-clicking the icon for your disk on the desktop and then choosing Get Info. The information is available under Format.
If it reads “Mac OS Extended (Journaled)”, congratulations, you successfully restored the grayed-out Disk Utility and your hard disk is now compatible with macOS.
Partitioning Your Hard Drive on Mac
Now that you have prepared your hard drive to work with Mac, the next step is to partition it on your Mac by following these steps:
- Launch the Disk Utility app on your Mac and highlight the hard drive icon under ‘External’ (for external hard drives). If you choose any other drive, the partition option will become unclickable.
- Now click Partition on the top toolbar. A window that has partition information will pop up. On the left side of the window, look for the name and the volume size of your hard drive. The next step is to click add(+) button on the bottom of the window to create partitions on your disk. Allocate the desired volume size to each partition.
- Hit the Apply button and wait for a window asking you to verify your choices. Confirm the changes by clicking the Partition button.
- Wait for the process to complete. You can confirm if the process was successful on your desktop. You will see additional disk icons show
Pro Tip: If the main reason for partitioning your hard drive is to install Windows, Apple recommends that you use Boot Camp Assistant instead of Disk Utility. You should, however, note that you cannot use Disk Utility to erase a partition generated using Boot Camp Assistant.

partition (plusswap) is probably the easiest, simplest way to go. However, if yourpartition is larger than around 6GB, choose ext3 as your partitiontype.

For multi-user systems or systems with lots of disk space, it's bestto put
/var
,/tmp
, and /home
each ontheir own partitions separate from the /
partition.You might need a separate
/usr/local
partition ifyou plan to install many programs that are not part of the Debiandistribution. If your machine will be a mail server, you might needto make /var/mail
a separate partition. Often,putting /tmp
on its own partition, for instance20–50MB, is a good idea. If you are setting up a server with lotsof user accounts, it's generally good to have a separate, large/home
partition. In general, the partitioningsituation varies from computer to computer depending on its uses.Best Mac Scheme Partition 2017
For very complex systems, you should see theMulti Disk HOWTO. This contains in-depth information, mostlyof interest to ISPs and people setting up servers.
With respect to the issue of swap partition size, there are manyviews. One rule of thumb which works well is to use as much swap asyou have system memory. It also shouldn't be smaller than 16MB, inmost cases. Of course, there are exceptions to these rules. If youare trying to solve 10000 simultaneous equations on a machine with256MB of memory, you may need a gigabyte (or more) of swap.

On some 32-bit architectures (m68k and PowerPC), themaximum size of a swap partition is 2GB. That should be enough fornearly any installation. However, if your swap requirements are thishigh, you should probably try to spread the swap across differentdisks (also called “spindles”) and, if possible, different SCSI orIDE channels. The kernel will balance swap usage between multipleswap partitions, giving better performance.

As an example, an older home machine might have 32MB of RAM and a1.7GB IDE drive on
/dev/sda
. There might be a500MB partition for another operating system on/dev/sda1
, a 32MB swap partition on/dev/sda3
and about 1.2GB on/dev/sda2
as the Linux partition.Best Mac Scheme Partition Free
