#951 MacOS version does not allow to install.

Laptop of a friend was updated to newer version of MacOS. The dmg file from download now refuses to run because apple cannot confirm if it is not malicious. See attached image. It requests to contact the developer for an update.

The software stopped working after the macOS update and the user attempted to reinstall with the same result.

As indicated at the end of the article about Sweet Home 3D 6.3:

I tried to noterize Sweet Home 3D under macOS, but the Java Runtime Environment and Java 3D versions currently bundled with Sweet Home 3D prevented me to succeed the notarization process. Until these required pieces of software are updated, the first launch of Sweet Home 3D under macOS 10.15 must be done with the Open item in its contextuel menu although the application is correctly signed.

I imagined it was something like that. Thank you. I am guessing this applies for the app version found in the mac shop. Thank you very much!

Fortunately, apps in the Mac App Store have different constraints. Sandboxing and noterization seem to be quite different processes. But for how long???

I can confirm that your suggestion of running program from context menu worked.

Installed it just now on MacOS 10.15.6 Beta. Got the complaint that it couldn't be used because Apple can't confirm it wasn't malicious. Left that dialog box up, opened System Preferences > Security & Privacy. Unlocked the padlock. Tried running again. Now a message appeared with an "Open anyway" button. Clicked that. Program runs.

This type of sequence is typical these days for these kinds of issues. Sometimes it wants to move the app to Trash. Best bet is to ignore that and go to Security & Privacy and try to get to "Open anyway". I think in the past I've even had to put something in Trash and retrieve it and then go back to the preferences. Different versions of macOS seem to operate slightly differently from each other.

Trying to get it working on a Macbook Pro / 10.15.7... keep getting the message: "“Sweet Home 3D” can’t be opened because Apple cannot check it for malicious software." Tried the trick with security & privacy, but the 'open anyway' does not appear. Tried to open it first time from context menu, no luck either. Strange thing is, we have another MBP, exact same configuration and there it works even with SW3D version 6.3.
Any more tricks to try?

The next version 6.5 will be notarized. Please confirm it works for you.

Sweet Home 3D 6.5 was released and notarized.
