Jellyfish and macOS 11 Big Sur

It’s official, macOS Big Sur is out and we are all excited about it.
Some of us more than others. Our team started using Big Sur as soon as the first developers' beta came to life. The experience has been promising since then. Now that the official version is out, we know many of the Jellyfish users are eager to find out if they are good to upgrade. 

Let’s take a look at some things you should keep in mind. 

Jellyfish Connect App

There have been no issues found with Jellyfish Connect and Big Sur. It works as expected. Discovery and mounting of the Jellyfish shares are unaffected. 

Network Performance

While we are excited about the performance on SMB Shares, we are a little concerned that we are seeing lower NFS performance. 

Network Adapters

If you are using a 10GbE to Thunderbolt adapter like the Sonnet Twin 10G, please make sure that the manufacturer of the adapter has updated drivers on their website. If they don’t, please do not upgrade at this time


No issues have been found yet with Premiere Pro, Final Cut Pro X, and DaVinci Resolve. Avid doesn’t have support for Big Sur yet.

It is rarely advisable not to download the first official release of a new OS if you are in the middle of a project and you would be risking being late for your deadline in case anything goes wrong. While we haven’t seen issues, that doesn’t mean other applications won’t be affected. We have found data in some forums that there are issues with Logic Pro. If you are using any plug-ins you should check with the developers and see if they are compatible with the new software you are planning to update to. 

Don’t forget that the Jellyfish is only one component of your entire infrastructure so make sure you check if all the other pieces also remain compatible.
