External drives · Choosing a drive
Can I use the same external drive with two Macs?
Short answer: Yes. Storage Studio keeps a separate folder for each Mac on the drive, so nothing mixes. But the drive can only be attached to one Mac at a time, and whatever a Mac moved there is unreachable while it's plugged into the other.
Yes. Storage Studio keeps a separate folder on the drive for each Mac it's set up on, so files moved from one Mac never mix with another's. Each Mac's shortcuts only lead to its own folder.
Keep in mind that a drive can only be plugged into one Mac at a time. While it's connected to your other Mac, anything this Mac moved to it isn't reachable here — apps won't open and moved folders appear empty until you plug it back in.
If both Macs need the drive most of the day, two drives is the more comfortable setup.
