See nothing when I open Anki on Mac

I haven’t found topics solving my problem, so I created a new one.

There are no any error messages at launching but I see an empty window. I tried to reinstall, install beta version but nothing helped.
MacOS Catalina 10.15.7

Wait for your suggestions guys. Currently I can only use it on Android, and yeah the Mobile version works fine.

Maybe https://changes.ankiweb.net/#/known-issues?id=blank-screens-and-egpus-on-macs

Aside from it, maybe start Anki while holding down the Shift key to turn off the add-ons - https://faqs.ankiweb.net/when-problems-occur.html.

If it doesn’t help, maybe try to run Anki from a terminal.

Thanks for your reply, @kelciour
I don’t have an option “prefer eGPU” in the Get Info menu.
I tried to start holding Shift but it didn’t solve the problem and I don’t have any add-ons.

What Terminal says:

Qt WebEngine resources not found at . Trying parent directory…

Qt WebEngine resources not found at /Applications/Anki.app/Contents/MacOS/PyQt5/Qt. Trying application directory…

I don’t know why the latest version doesn’t work on my system but I tried different versions and this one solved my problem 2.1.35 (84dcaa86)

You might as well upgrade to 2.1.38 which is the latest released version.

Yeah, I tried the latest one but didn’t succeed) Currently I can only use Anki on 2.1.35
Thanks guys for your suggestions!
Actually I’ve solved the problem (empty window instead of GUI) by installing an older version of Anki, 2.1.35 in my case.

What’s your MacOSX version? 2.1.38 works fine with my MacBookPro 2017 MacOSX 10.15.7. Also, disable add-ons temporarily to see if one might be causing the problem. You can do both of these things by holding down the Shift key while starting Anki.

You could try

echo ‘software’ > ~/Library/Application\ Support/Anki2/gldriver

in a terminal to see if that helps with 2.1.38.

Thanks, @dae
I gave it a try, nothing positive occurred with 2.1.38
Thanks again to all of you guys! So I prefer to stay at working 2.1.35

@khs 10.15.7 It’s indicated in my first post here)

Is there any updates on this issue? Here is what I have found while playing around.

Devices:
Macbook pro 2016 Catalina 10.15.7
Anki JUST WORKS

Hackintosh with Catalina 10.15.7 (AMD RX580 Radeon GPU - NOT EGPU)
It produces this blank screen just as the OP as.

I found out that following this guide and running Anki from Python WORKS: Running from Python - Frequently Asked Questions

So what is the difference between what I download on Github and the pip/python installed version? Is it a newer version of Qt or something?

This solution doesnt work for me because this is not the user experience that I want. I don’t want to have to use command line just to launch anki. I want it to be an APP just like everything else on my computer.

BTW the other workaround that I have been using is to use a very old version 2.1.35 (Alternative). Only the alternative version works!

Please take some pity on us users unable to enjoy the benefits of newer versions. What other information can i provide?

Have you actually tried installing Qt, then Anki from github? From the error message I have the impression that Qt fails to locate some of its core resources (the Qt WebEngine resources), which are responsible for rendering widgets, so it is very plausible that it is the reason why the window opens, but it doesn’t render anything.

Incidentally, pyqtwebengine seems to be a package on its own, so make sure it is installed when installing Qt.

BlackBeans,
Thanks for the quick reply.

Sorry, i want. to rephrase, i meant the diff between the Release from github (not compiled code) and the pip install. I didn’t want to sink more time into doing that but something else you said triggered something in my memory:

I was trying to diagnose the issue and looking in mac’s Console app while Anki was starting and saw information related to the webview resources:

default	13:28:28.329062-0400	AnkiMac	Qt WebEngine resources not found at . Trying parent directory...

I did a git clone of the repository and ran the ./run script to build and run anki from source. This also worked. However like the pip solution, doesnt result in a packaged Mac app, just a python wheel.

It appears this problem only occurs from the packaged Anki.App files from the releases section of Github. Honestly I would settle for being able to produce the mac app file somehow if theres no way to do an upstream fix. I dont understand why one works and not the other.

When you install from pip you’re pulling in the latest Qt version, which Anki doesn’t use due to various issues it has, which will hopefully be addressed in the future.

I’ve posted a janky, temporary workaround in this other thread.

Hopefully it helps one of you, until this probably-bug-in-QT is fixed — although I’m not optimistic, because it looks like similar bugs have gone unfixed in a large, large number of other qt applications. I suspect it’s just something that only applies to a small portion of macOS users? (Was anybody else on this thread on a MacPro7,1 with AMD Radeon Pro Vega graphics?)

Thanks. Disappointed to say the recent 2.1.50 Qt6 releases of Anki have still not fixed this situation.
