How to create new folder on mac external hard drive

To avoid that, select the drive in Disk Utility, click Erase, and follow prompts to create a single APFS container. But reports indicate that you may not be able to just change the formatting on an existing drive, as invisible partitions used for purposes related to booting from an Intel drive from a previous macOS installation on the drive could cause issues. To use Big Sur, the drive has to be formatted as APFS. I opted to buy a relatively inexpensive 500GB SSD for now (about $75) so I could have a bootable option. (That sounds like a mouthful, but you can search on that to find compatible SSDs.) OWC says it supports current capacities up to 4TB, and is designed to support future higher capacities, too. You can purchase higher capacities, or just get its Envoy Express enclosure, which runs $79, to which you can add any SSD thatвЂ™s designed for the 2280 M.2 NVMe standard. With an SSD inside, OWC charges $199 for 480GB and $299.75 for 1TB. (Some people have apparently been able to get a USB 3 drive to work for this, but no one has narrowed down which ones or why, so itвЂ™s impossible to recommend it as a course of action.)

However, Other World Computing offers a specific line of lower-cost, bus-powered Thunderbolt 3 SSDs. Thunderbolt 3 is generally reserved for high-performance drives and arrays of drives used for graphics and video purposes. Most inexpensive external drives use a flavor of USB 3 to connect over USB-C.
