CONVERTING TO APFS - Apple Community

" It is not mandatory. If you upgrade to Catalina it will reformat to APFS automatically. If you want your internal drives to be APFS you can convert those by restarting your Mac by using Command + R to boot into recovery mode. Then, from Disk Utility>View>Show All Devices> Select your parent drive (or external) then click Edit and Convert to APFS. It will not impact your files. Before doing any conversion be sure you have a backup just in case. "

Hi amtekel,

In reference to your question, you would have to format to Apple File System (APFS) in order to install macOS Ventura. APFS is the default file system needed for macOS 10.13 or later. Please keep in mind that formatting would erase the data in your current storage. It's recommended to create a back up of your data. For directions on formatting your storage, you can follow these steps:

Erase and reformat a storage device in Disk Utility on Mac

In Disk Utility on Mac, you can erase and reformat storage devices to use with your Mac. Erasing a storage device deletes everything on it.

1. If you have any files you want to save, copy them to another storage device.

2. Open the Disk Utility app  on your Mac using one of the following methods, depending on the type of disk or volume you want to erase:

* If you want to erase your startup disk: Start up your computer in macOS Recovery, then choose Disk Utility in the Recovery app. To learn how to start up your computer in macOS Recovery, see Intro to macOS Recovery.

* Note: If you want to get your Mac ready to trade in, sell, or give away, and your computer is a Mac with Apple silicon or an Intel-based Mac with an Apple T2 Security Chip, use Erase Assistant.

* If you want to erase any other type of storage device: Double-click Disk Utility in the /Applications/Utilities folder.

3. Choose View > Show All Devices.

4. In the sidebar, select the storage device you want to erase, then click the Erase button .

5. Click the Scheme pop-up menu, then choose GUID Partition Map.

If the Scheme pop-up menu isn’t available, make sure you selected the storage device you want to

erase—it’s at the top of the hierarchy.

6. Click the Format pop-up menu, then choose a file system format.

7. Enter a name.

8. (Optional) If available, click Security Options, use the slider to choose how many times to write over

the erased data, then click OK.

Secure erase options are available only for some types of storage devices. If the Security Options

button is not available, Disk Utility cannot perform a secure erase on the storage device.

9. Click Erase, then click Done.

Following these steps will help you on the path to formatting your storage and having the ability to update your Mac to macOS Ventura. These steps are outlined in this article: Erase and reformat a storage device in Disk Utility on Mac - Apple Support

Kind regards.
