Sabrent SB-TB4K Reviews

excellent KVM switch for Mac's with Thunderbolt displays

By Marc

I've been looking for a solution for quite some time, this KVM switch works really well - I have two MacBook Pro's (personal Mac (M1) and work Mac(M2)) connected to two Apple Studio Displays (5k), and I can now easily switch between the two Macs.

For Mac users, this is magic.

After a lot of research and an initial wrong purchase (since returned), I came to B&H seeking a solution for my two Macs / 1 5k monitor setup. After chatting with a very helpful B&H rep, we identified this Sabrent TB4 KVM as the correct choice, and it definitely was. It arrived quickly, it's got excellent build quality, and it's crazy easy to set up and use. THANK YOU SABRENT AND B&H!

Can wireless keyboard and mouse be used with a pc laptop and mac mini and studio display setup?
Asked by: Nick
Yes, as long as the wireless mouse and keyboard are using USB wireless receivers. If they are connected via bluetooth, you will need to change the connection over to the second computer manually.
