Cannot launch Spyder after updating to macOS 11 Big Sur, please help. #14222
Comments
|
Same here. On all three of my Macs the same thing happened. After upgrading to Big Sur Spyder starts but the IDE never shows up. When I click on the Spyder icon in the dock it does not switch to Python in the title bar as before but stays in the terminal. I reinstalled my virtual environment, 3.9 then back to 3.8 it is the same. Any idea? |
|
I'm also experiencing this issue when attempting to launch Spyder using Anaconda Navigator. After upgrading to Big Sur, the Spyder icon will appear in the Dock, but never load. When attempting to load Spyder from the Terminal, it appears to never make it past line 3 of: /Users/adam/opt/anaconda3/envs/icebergdrift/bin/pythonw Additionally, Keen to learn what the cause and/or solution is! |

Hi Adam,
I am not using anaconda, so it is a more general issue. I just launch Spyder from the command line and the same thing happen. I hope it gets fixed soon because I use Spyder every day.

Additionally, spyder --debug-info verbose --debug-output file does not produce any debugging information to the Terminal.

The same issue happened to me after updating to Big Sur. I don't know why, but I somehow resolved this issue by following the method as indicated in the following issue: More specifically, I tried the following steps:
Although I am able to launch and use Spyder now, there are some latency issues, as reported in the following issue: |
|
I tried everything you said, still no luck. |
|
I had successfully installed Spyder in Big Sur without Anaconda. I installed the python 3.9 from homebrew and made it default, then I installed Spyder via pip, it works fine, with no delays or writing. |
|
@bendermh, thanks for digging deeper into this! Could the others download our macOS appilcation and see if it works for you? According to what @bendermh posted above, it should. |
|
Hi @ccordoba12, I attempted to install Spyder using the macOS .dmg file you provided but the program doesn't load. The icon appears in the Dock, but stops responding. Would having Anaconda installed cause a conflict with running Spyder on its own? Cheers, |

@ccordoba12 It's the same for me. The |

I'll try to update to Big Sur this evening. In the meantime, could someone that feels confortable doing that try cloning the repo (see instructions at https://github.com/spyder-ide/spyder/blob/master/CONTRIBUTING.md#setting-up-a-development-environment), and run spyder with |
|
Pyzo users on Big Sur are experiencing the same issue. @ccordoba12 I also ran a new CI build this morning using Python 3.9 and the latest PyInstaller, but this seems not to fix it, which seems similar to the experience with Spyder, I think. Let's keep each-other informed :) |
@impact27 I tried the method you suggested on the branch 4.x, and the latency issue was not resolved. Also, I got the following output in the terminal: |
|
@wenlzhang thanks! That means that Spyder did launch? There might be two different problems:
|
@impact27 I should have been more clear in the description... Spyder launches successfully but it has a very slow response. |
|
@wenlzhang, please run the following commands to see see if that helps:
If that still shows slowness, please run
|
Hey @almarklein! Sure, we should keep in touch. I think the problem is because Anaconda ships with a very old Qt version. Things should be fixed with Qt 5.12 (our current pip requirement) or 5.15 (hopefully). |
|
@ccordoba12 Neither of the two methods worked. Spyder would not launch this time, and I had to Force Quit Spyder from the Dock. With the first method, i.e. the following steps:
I got the following output in the terminal: With the second method, i.e. by using the following commands:

Ok, thanks for trying. Could you post a screenshot of what you're seeing? |

@ccordoba12 Besides the terminal output described above, nothing else is special to me. The Spyder icon pops up in the Dock as follows, but Spyder does not launch. When I right click the Spyder icon in the Dock, it says that Application Not Responding. Also, |

I updated and can't reproduce with : |

Great news @impact27! Two additional questions for you:
|
|
The Mac app fails to start. I am not even sure it actually loads spyder code before blocking, so this could be PY2APP related. I will investigate further later.

Just tried downloading the dmg and get the same issue as @wenlzhang. Spyder icon pops up and down on dock then gets marked as opened but no window ever appears and I have to Force Quite Spyder because it's not responding. I also have Spyder installed via conda and that still opens up fine on Big Sur :). Even with multiple environments and changing python interpreters. But when opening the conda version I am getting the very high latency on keystrokes as mentioned in #14218. |

I could use this technique to launch the macOS appilcation but it is a bit laggy (not as bad as with Qt 5.9): https://stackoverflow.com/questions/16184505/set-environment-variable-for-the-process-before-startup You need to add to Info.plist is cached, so it might not work directly. If that doesn't work, the solution is to kill and rebuild the cache:

You probably didn't run it in the correct environment. You can just uninstall everything and try again. Let me update the instructions: Run: |
It helped - thank you! |

Thank you @impact27 ! Got the same issue. It worked fine for me. |

Thank you @impact27 ! When I first "upgraded" to Big Sur, Spyder 4.1.5 was running from Anaconda, but today it was not. I tried the direct install (Mac OS) but it was not working. I run just the lines:
On my existing environment and it worked (launches 4.2.0), although the pip install means that Anaconda Navigator is not recognizing Spyder 4.2.0 and the app doesn't work. Any long term solution? Thanks Marcos |
We can probably add QT_MAC_WANTS_LAYER=1 to spyder so you wouldn’t need to set it. To make conda work instead of pip however we probably need to wait for conda to update the Qt version they distribute. The app can be updated however |
|
I download the Spyder app, when i try to open it, it shows as the picture below. Which is almost the same when i open annaconda, so far, i can only open jupyter lab through terminal, i try to call Spyder(Anaconda) from the terminal, it result the same thing as a try to open the Spyder app alone.

I've made a new build for Pyzo that does |

Hi all, I am experiencing this issue with spyder, but I also seem to be getting the exact same symptoms when I try to launch anaconda navigator (icon appears in dock but will not open). It seems like big sur has potentially caused a wider anaconda issue? |
|
I can use Navigator and JupyterLab, but not Spyder and Notebook. |
thank you so much, this works for me!!!!! |
|
just wondering, now Spyder from Anaconda works for me, |

Sorry guys but I'm going to lock this issue because it's starting to accumulate incorrect answers (some of which are very bad advice). Bottom line is this:
Thanks for understanding. |
and others
After updating my OS to macOS 11 today, I cannot seem to launch Spyder. I tried reinstall everything even reconstruct the python framework. Still does not work. When I run the following command in my terminal, the Spyder icon pops up but it stops there, nothing is being loaded and the Spyder window do not show up.
I am not using Anaconda, I installed Spyder using pip.
How can I fix this? Thanks.
