1. Download and Open

[i0nicsBik]

Any workaround or fixes?

[grossmj]

Any workaround or fixes?

Yes, that would be to manually install GNS3 using Python pip etc.

[grossmj]

I understand that macOS Big Sur will be released later in 2020. We will wait for the final release.

[grossmj]

We will try to work on it for the next release.

[grossmj]

Still waiting for the final release.

[Vardiak]

macOS Big Sur is expected to launch tomorrow, this should be prioritized...

[tthoma24]

Still waiting for the final release.

Access to the beta has been and still is available. Has work started on this, and if not, how can I help?

We don't have a Mac to do tests, we use VMs instead. We will test very soon. Please can you try to launch the latest version of GNS3 and let us know if you see any error message or any logs? Thanks :+1:

Also really weird about gns3 version it detects, I am 100% sure it is 2.2.16.

/Applications/GNS3.app/Contents/MacOS/gns3 --version
2.2.16

[tao-lian]

Upgrade to 20B28 yesterday, GNS 3 still cannot load.

TBH, there is also big issue with VMWare Fusion 12 cannot do nested virutalisation. It does feel like it will be some time before GNS 3 + VM can work properly

[grossmj]

Thanks for the info. Also, we will need xcode support for 11.0 on CircleCI https://circleci.com/docs/2.0/testing-ios/#supported-xcode-versions (this is where we build our macOS app).

If you have nightly build to test on Big Sur, I am more than happy to help. But as I mentioned above, neither VMware 12 nor virtualbox can run properly on Big Sur, I believe they have more problems than GNS3 ^_^

[Vardiak]

@tao-lian what I have done is install GNS3 GUI on a Lubuntu VM on VirtualBox & another a GNS3 VM side by side. Then, I connect to my GNS3 VM from my Lubuntu VM as if it was a distant server.

It seems to be a bug in pyqt5 and they have filed the bug (Some rumors that 5.13.1 is still working). Many other projects using python fixed it already. I found a dirty workaround to get the sources running on Mac by adding this 3 lines to the top of the main() function.

import matplotlib
import matplotlib.pyplot as plt


matplotlib.use('TkAgg')

I dont't know why, but it's working. Maybe there are some dependencies or hooks imported with these lines.

Hopefully it will be fixed soon.

[twagener]

It's running with this PyQT Version

pip install pyqt5-sip==4.19.19 pyqt5==5.12.1

It would be really great to have version 2.2.13 bundled with this pyqt version! Because 2.2.13 is the last stable version for macOS.

Upgrade to 20B28 yesterday, GNS 3 still cannot load.

TBH, there is also big issue with VMWare Fusion 12 cannot do nested virtualization. It does feel like it will be some time before GNS 3 + VM can work properly

It seems resolved since Fusion 12.1.0 (my GNS3 VM is launching while having enabled VT-x support).
See release notes:
https://docs.vmware.com/en/VMware-Fusion/12.1.0/rn/VMware-Fusion-1210-Release-Notes.html

And below extract:
"Nested virtualization is now supported on the CPU models without the VMCS shadowing feature."

They fixed it in 12.1 indeed! However, there is another very annoying issue is NAT does not work for me!
https://communities.vmware.com/t5/VMware-Fusion-Discussions/macOS-Big-Sur-Fusion-12-NAT-no-internet-connection/td-p/2809034

I know I can bridge the network, but I remember GNS3 not recommand to bridge to a WIFI NIC. I havent tried recently, but in my memory it wasnt very stable.

Do you know which ones? Thanks :+1:

Mine for example. You need the right pyqt versions. I used these pip install pyqt5-sip==4.19.19 pyqt5==5.12.1

Unfortunately, it is not easy for us to upgrade because freezing apps is a nightmare.

However, I found a workaround. With GNS3.app in /Applications, open a Terminal and type this:

QT_MAC_WANTS_LAYER=1 open -a GNS3.app

[grossmj]

Looks like all I need to do is to add os.environ['QT_MAC_WANTS_LAYER'] = '1' in our code. This will be done in version 2.2.17

[jnatschev]

i'd like to share that i have managed to get GNS3 GUI 2.2.16, GNS3 Server 2.2.16, and GNS3 VM 2.2.16 to launch and give me the GUI and connect to the server and VM. the way i did it is to use python 3.7 (the latest) use pip to install gns3 gui and gns3 server on MacOS Big Sur. then:

1. start GNS3 VM on VMWare Fusion
2. python -m gns3server (no errors)
3. python -m gns3 (no errors)

This is as far as i got. need to download a csr1000v image to test further. i'm encouraged so far.

Cheers,
John

[grossmj]

@jnatschev thanks for sharing :+1:

[jnatschev]

further update.

i downloaded a csr1000v image, 16.12.04a, modified the gns3 csr1000v appliance file to include this version of the csr1000v and have successfully added two csr1000v routers into a topology, configured to do bgp between them.

i can say job done. their working fine.

so:
macos big sur
vmware fusion 12.1.0
gns3 gui 2.2.16
gns3 server 2.2.16
gns3 vm 2.2.16

also, be aware, the python installation is via anaconda (conda). i created a specific "environment", named gns3-3.7, for gns3. pip install didn't seem to install sip and PyQt. so i did a conda install -n gns3-3.7 PyQt. this installed the needed PyQt packages and sip. next i'll try with a new conda environment using the packages from the conda channel conda-forge.

fingers crossed

[matthieugouel]

For today, I succeeded to launch GNS3 (2.2.16) from command line with :

pip install pyqt5-sip==4.19.19 pyqt5==5.12.1
export QT_MAC_WANTS_LAYER=1
open -a GNS3

[grossmj]

Our last nightly build should work on Big Sur: https://sourceforge.net/projects/gns-3/files/Nightly%20Builds/2020-12-01/2.2/GNS3-2.2.17dev1.dmg/download

[grossmj]

I consider this issue to be solved. Next version, 2.2.17 will work on macOS Big Sur. Thanks to everyone who helped and please comment back if you find issues running the latest nightly build.

Hello,

Do you know when this will be released ?

Best regards

[grossmj]

Today or tomorrow.
