A internet is bang-up , but what if you just want to connect two Macs and remove gobs of info as tight as you’re able to ? Using a Gbit ethernet cable length or a Mac with 802.11ac ( Wi - Fi 5 ) or later wireless networking computer hardware , you’re able to transfer data between two devices at Gb per 2d charge per unit — but you’re able to do better than that !
Apple offers four work up - in methods in macOS , none of which are obvious to set up . Each of them has different requirements , advantages , and trade-off . Once plug in , you employ the same tool to transfer selective information between two Macs as you would if they were connected to a internet :
Here are the four methods , from fast to slowest .
A self-assigned network starts with 169.254., but you can still connect to it from the Network browser.
Connect via Thunderbolt
Thunderbolt has long include a computer - to - computer mode that allows a 10Gbps connection . While that ’s a fraction of its current 40Gbps data path for drives , peripheral gadget , and displays , it ’s speedy enough ! ( This method acting works with Windows and other figurer that have Thunderbolt funding , too . )
In my testing using a Thunderbolt 4 cable system between two M1 Macs , I was capable to get 4Gbps of free burning writes and 8Gbps of free burning read using a speed - examination app , and 5Gbps in copying large files from one Mac to the other . Both rates are far above gigabit ethernet .
It ’s vitally significant that you have a USB - C to USB - ampere-second cablegram designed for Thunderbolt 3 or 4 . Buy it from a party that has a good data track disc , such asAnker , Belkin , CalDigit , andOther World Computing , to name four of many . If you already own a USB - ampere-second cable , check that it has a lightning bolt of lightning symbol on plug at both oddment ; it should also expect a 3 or 4 , though Apple omits that , oddly enough . You do n’t want a USB - C charge - only cable ( typically unmarked ends ) or a USB 3 - only cable ( typically a USB symbolisation and SuperSpeed+ or SS+ , SS 10 , or SS 20 recording label ) .
The Thunderbolt-to-Thunderbolt connection will appear with a yellow dot and Self-Assigned-IP in the Network preference pane.
If you have one or two older Macs with Thunderbolt 2 , you’re able to use a Thunderbolt 2 to Thunderbolt 2 cable television or a Thunderbolt 3 or 4 USB - C cable system witha Thunderbolt 2 adapteron one last .
Here ’s how to set it up :
To disconnect , simply unplug the Thunderbolt cable system .

Connect via 1Gbps to 10Gbps ethernet
macOS can also automatically configure a web connection over ethernet between two Macs with the same outcome above : a self - assigned IP address . Some Macs — like the Mac Pro and Studio Mac — have built - in 10Gbps ethernet . Macs released in the last decade have 1Gbps ethernet , known as plain “ Gbit ethernet . ” To use 1Gbps ethernet , you require a line rated as Category 5E ( or Cat5E ) or high ; for 10Gbps , at least Cat6 . ( If you require to use 10Gbps on a local mesh , you could get a10 Gbps ethernet adapter for Thunderbolt 3 or 4for a thumping $ 199 . )
OpenSystem Preferences / configurations > Networkand check that Ethernet appears in the leaning of interfaces . If not , follow the steps above for Thunderbolt to add an Ethernet port . Connect the two Macs with the cable’s length , and you ’ll wind up as in step 4 above for a Thunderbolt cable .
you may connect with information processing system run other operating system , as they broadly also automatically make a ego - assigned IP address and reserve SMB and other networking services .
You can create a secure Wi-Fi network managed by your Mac in the Sharing preference pane.
carrying out should be up to 1Gbps with gigabit ethernet and check Thunderbolt performance with 10Gbps ethernet .
Create a Wi-Fi hotspot with your Mac
If there ’s no Thunderbolt or ethernet cable television handy and no Wi - Fi internet nearby , you may employ your Mac to create a Wi - Fi hot spot , once called asoftware base post . ( Apple began including this feature decades ago . )
Read “ How to partake in a Wi - Fi connection via macOS ” on how to configure one Mac to extend such a meshwork . You useSystem Preferences > Sharingrather than the web predilection pane . ( Visit the web preference window glass and it shows net Sharing : On as the internet Name for the Wi - Fi adapter . ) Your Mac also establish an upward - pointing arrow inside the Wi - Fi devotee to indicate web sharing .
Once created , the Mac ’s Wi - Fi web can be choose by any twist with Wi - Fi . That includes Macs , gaming systems , Android phone , and anything else . Because this is a shared connexion , the auto connected to your Mac will be assigned an IP savoir-faire by your Mac .
To create the network, you name and pick a channel (left, as in step 4), and then confirm the creation (step 5).
With my Macs — an M1 MacBook Air and M1 Mac mini — I achieve between 100 and 200Mbps of throughput , about half what I could manage via a Wi - Fi web to a gigabit net connectedness .
A Mac - created Wi - Fi hotspot is in force in a pinch when no other web or cables are useable , but an 802.11ac ( Wi - Fi 5 ) or by and by Wi - Fi router can declare oneself more throughput , often making it a good choice .
deactivate the Wi - Fi hot spot by unchecking the Internet Sharing service in the left - hand tilt in System Preferences > Sharing .
Create a computer-to-computer wireless network
As the last resort , you could revert to an onetime wireless method acting once known asad hoc . It ’s out of date and miss Wi - Fi security measures . Still , it has very little overhead because it ’s a peer - to - peer connexion — just verify nobody is in range who could sniff your unencrypted wireless data point .
Your maximal throughput will be relatively low . I measure below 100Mbps , even lower on modal than with a Mac - created Wi - Fi hotspot .
To unplug , chatter the Wi - Fi symbol to the left of the internet ’s name on the Mac that ’s share-out . bend off the internet on the Mac that ’s sharing by clicking that Wi - Fi symbolisation under gadget .
