Mar 28 2026 APP 2.0.0-beta40 will be released in 7 days.
It did take a long time to have the work finished on this and it will have a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration. We extensively optimized many critical parts of APP. All has been tested to guarantee correct optimizations. Drizzle and image resampling is much faster for instance, those modules have been completely rewritten. Much less memory usage. LNC 2.0 will be released which works much better and faster than LNC in it's current state. And more, all will be added to the release notes in the coming weeks...
Update on the 2.0.0 release & the full manual
We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.
Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.
Indeed, fully understood. To fix a bug, you need to be able to reproduce it.
I'll be happy to support if you need specifics about my environment.
Thanks
@rodolgo Glad to see you are making progress as well! And thanks for the offer to let us know any system specifics.
update - no matter what I try this morning APP hangs. back to square one. I so hate to have to use BP in Pix.
@favalessa Sorry to hear that. Would you have any idea what may have caused that?
no idea. I rebooted. I set to auto load at start. rebooted. I unchecked auto load at start. rebooted. no luck. then I set auto load at start again, rebooted, frozen APP, but after an hour it opened!
After an HOUR? Wow. And your MacBook is connected to internet, isn’t it?
It pretty much looks as if something with this startup dialog causes the problem. When APP gets the working directory, all seems to work fine.
It should be extremely easy to make a build of the current version without the startup dialog - using an APP created default directory instead as the working directory. If this works, we know definitely where the problem lies and also have a working version until a final fix is there.
Best regards,
Eckhard
yes exactly! there are some other visual quirks going on, but they do not affect the processing.

@vincent-mod Ah! Thank you. I'll look it over when I get back from lunch.

I got excited when I saw the email that there was a new post this morning, but it just refers to an older post by Mabula. My progress is going in the wrong direction. update:
recently past few days I cannot get APP to open as just hangs on directory screen at boot up. I've tried everything 10x times. (rebooting, reinstalling, following all the directions, etc) I'm giving up. I hope the team is working on a fix.
I think that this will not resolve your issue, but I was struggling for days to make my SAP GUI environment to run properly with dialog boxes (MacBook Pro, Big Sur) and I've just resolved it.
I've changed the System Preferences-->General-->Prefer tabs to NEVER.
@euripides Thanks for the tip! What was it set to before you made that change? For me it is set to "in full screen" and APP runs perfectly OK on Big Sur.
@wvreeven Mine was at full screen also, that it seems to be the default for Big Sur and APP works without issues.
Hello Euripides, hello Wouter,
to paraphrase the ancient Greeks ... Eureka! 🤗
Perfect!!!!!!!!! 🍷
That is the solution!!
Now works on my iMac too!
Jürgen
Euripides that fixed it for me also!!! restarted APP 10 times in a row with no issues or rebooting. this fix is so obscure, way to go! hours of frustration no more...life's simple pleasures.
That’s great guys! 🤩
Really glad I was able to help. Hope at least to this solve the issue once and for all (or at least Mabula finds what to do to avoid further future frustration)
Even if I am an Apple technician (not in software), I always messing around with software too. Trying to fix bugs is my second hobby 🙂
I confirm: it also works as expected on my system. Good workaround and congrats for figuring it out 🙂
FYI: I just changed the settings from "always" to "in full screen" (not sure about the exact wording in English, as my system is running with the French locale). I also successfully tested the "never" settings. And moving back to the "always" settings causes APP to fail loading.
I can confirm this as well now. When I set "Prefer Tabs" to Always", APP hangs at start up. When I change it back to "In Full Screen" APP starts normally. I passed on this info to Mabula so he can investigate and implement a fix for this.
I can also report that all the TOOLS are working now with this fix! When I was able to get APP working before, the tools would freeze the system and would have to force quit.
Excellent, that should finally point us to why this is occurring. Very obscure bug, thanks everyone!
