A good way to separate your data is to partition your Mac hard drive. A partition splits your storage into two spaces, like putting a trunk divider in your car. The most common use case is to install a second operating system on the same computer. In college, I had a separate partition so I could boot into Ubuntu, and a third partition with Windows. With today’s Macs running Apple silicon, there’s no easy way to natively install Windows or Linux… yet.

But you’re probably here so you can install the beta version of macOS 13. The developer beta is anticipated for release the first week of June at WWDC22, Apple’s annual developer conference. The smart way to install it — especially with the developer betas, which can be notoriously rocky — is to use a separate partition.

The Mac comes with a very handy tool to partition your hard drive for free. Read on to partition your hard drive with Disk Utility.

Beware! OS X Lion Can Hose Your Recovery Partition! Here’s How You Can Try To Fix It



Apple’s new MacBook Air models don’t ship with OS X Lion on a USB thumb drive like they used to. That diminutive little white wedge of flash storage is gone, no where to be found inside of the box that these computers ship in. If you want one, you’ll need to pay Apple $69 for the privilege in August.

That’s a potentially big problem for some users. Yesterday, I found this out the hard way after an attempt to install Mac OS X Lion onto a 32GB Class 10 SDHC card failed. Apple’s failure to ship their new Macs with any media can leave you with a hosed Recovery HD partition, and a potentially lengthy fix may be the only way to get it back.
