Can't open updated anki on Mac

MacBook Pro M1 Pro, macOS 26.5.1
Anki Apple Silicon arm64 does not open. It bounces/hangs, no window appears.

Tested:

  • current Anki Apple Silicon
  • older Anki version
  • new macOS user account
  • fresh profile
  • removed NEURON x86_64 from PATH and PYTHONPATH
  • installed Xcode Command Line Tools
  • reset caches/preferences/saved state
  • removed Dock shortcut and opened from Applications

Diagnostics:
spctl --assess --verbose /Applications/Anki.app
=> accepted, source=Notarized Developer ID

codesign --verify --deep --strict --verbose=2 /Applications/Anki.app
=> valid on disk, satisfies its Designated Requirement

file /Applications/Anki.app/Contents/MacOS/Anki
=> Mach-O 64-bit executable arm64

sample output:
Main Thread: _dyld_start only
Physical footprint about 96K

log show --predicate ‘process == “Anki”’ --last 10m --info --style compact
=> no Anki log entries

Hope someone can help, I’m in the middle of studying :face_with_spiral_eyes:

You call your Anki “updated” – but also say you’re using an “older” Anki version. What version of Anki is it? Has it been working and it suddenly stopped? Or did you just “update” to a different version and this version has never worked on your system?

Sorry I tried so many things for hours and my brain is fried.

I just a version from 2022 (can’t tell you which one), never updated it, but I wanted to download an add on today, but it didn’t work. So my friend told me to update anki and I did (the latest version), but it didn’t open. So I deleted my old version and tried lots of things as well as download some versions from last summer and 2024, because chat gpt recommended them, but none of it worked. Now I’m sitting here with no functional anki on my laptop :frowning:

Got it. Are you sure downloaded the correct build of Anki for your chipset? Did you follow these install instructions – Install & Upgrade - Anki Manual ?

If so, and since you’ve tried a number of different versions at this point – I think it’s a good idea to try a fresh install. Go to these locations – Managing Files - Anki Manual – and delete the program folders. [Please note that I am not suggesting you delete your collection from your device! Your data is stored separately in your Anki2 folder, and you should leave that exactly how it is.] Then do a fresh download of the right build from the main site – Anki - powerful, intelligent flashcards – and follow the install instructions above.

If you continue to have problems after trying the suggestions above, please try running Anki directly from the Terminal app. If you are using the latest 26.05 version of Anki, the command: is:
/Applications/Anki.app/Contents/MacOS/Anki

Doing so will allow you to see the messages Anki prints as it runs, including any error messages. If you see error messages, please copy and paste them here.

I did all of the above - still doesn’t work.

Is the code correct? There is nothing happening.

Thank you both for trying to help me!

MacBook-Pro-7:~ name$ /Applications/Anki.app/Contents/MacOS/Anki

That’s the terminal code

I was just about to close the Terminal when it said, “Running processes: Anki is being closed. Are you sure?” But when I click on the app in Finder, it isn’t running.

What messages do you see in the Terminal when you run the /Applications/Anki.app/Contents/MacOS/Anki command? And, how long did you wait before trying to close the Terminal app?

Edit: Added:

When I run the command on my M1 Mac Mini running macOS Tahoe 26.5.1, the Anki app starts and in the Terminal I see…

% /Applications/Anki.app/Contents/MacOS/Anki
2026-06-24 15:08:57.030 Anki[54051:17570700] No Python NSLog handler found. stdout/stderr will not be captured.
2026-06-24 15:08:57.030 Anki[54051:17570700] To capture stdout/stderr, add 'std-nslog' to your app dependencies.

I’m wondering what messages you see when you run the command, how far you get before it hangs, etc.

Nothing unfortunately… I waited about 5 minutes and when I want to close the terminal again, ist says: If you close this window, this running process will be terminated: Anki

My mac has the latest macOS Tahoe 26.5.1 update

So, when you run the /Applications/Anki.app/Contents/MacOS/Anki command, absolutely nothing gets printed in the Terminal? You don’t even see those initial Python NSLog info/debug messages?

If so, we know that the Anki command is indeed running. However, for unknown reasons it isn’t getting very far. It doesn’t even get to the “Starting Anki” part where the main part of the app starts running.

Could you please provide the output of this Terminal command:
echo $0 ; ps -p$$ ; echo $SHELL

It prints the shell you are using in Terminal (in 3 different ways). I just want to check to see if you might be using a non-default shell.
On my Mac, I see that I am using the default zsh shell:

% echo $0 ; ps -p$$ ; echo $SHELL                     
-zsh
  PID TTY           TIME CMD
 1827 ttys002    0:00.93 -zsh
/bin/zsh

Could you also please provide the output of this Terminal command:
which python3 ; python3 --version

It prints the location of python and runs python to have it print the version number. I just want to check to see where your copy of python is located and if it can be run successfully to print its version.
On my Mac, this is what I see:

% which python3 ; python3 --version
/usr/bin/python3
Python 3.9.6
