Ver 7 compile time


I deleted the app and files then re-installed it is working okay now.


Back in work today and the compile times are back to over a minute again.

Same if I set the default browser to chrome.


It’s something on your Mac - this isn’t caused by AppStudio.


I use another ride ( Hype ) and that has no issues.
I didn’t have any issues with ver 6.

This what I am getting in the Activity Window when I run in browser.


The only other think I can think of is to delete the registry entry:

On a Mac, you need to delete

~/Library/Preferences/App Studio Preferences


You’re not crazy - I’m seeing this here all of sudden too. We’re looking into it further…


We’ve tracked the problem down a bit more. It seems to happen on Mac OS Mojave (10.14.2), but not on older versions of the OS. If you have the problem, let us know what version of MacOS you’re using.

The specific command which causes the problem is, which means anything that opens a web page from AppStudio (like Start in Desktop Browser and the Help features). This suggests workarounds: If you deploy to Volt, then paste the link into a browser, you won’t get the delay. You can also use Deploy to Local Server, so long as you open the app from your browser and not through AppStudio.

We will continue to work on this.


Work Mac ver 10.14.1 (18B75)
Home Mac ver 10.14 (18A391)

Same problem on both machines.


We have reports that it’s OK on High Sierra (10.13).

The problem also happens with AppStudio 6 on Mojave (10.14).



both machines upgrade to 10.14.2 with the same issue.

Some progress - here’s a workaround which works on the systems here:

Start Terminal and enter this:

open /Applications/

This will start AppStudio directly.


A new build of AppStudio for MacOS was just uploaded. It should solve the problem.

The cause was new security in MacOS Mojave. To fix it, we implemented proper app signing.

You can download the new build here:
(no update needed for Windows)


I have installed ver7.1.0

I am still getting the same speed issue.

If I use open /Applications/ everything is okay.

I just uploaded a fresh build - this time. Let me know if it makes any difference!


Hi which link is it ?


It’s the same link:


I have download twice and get the error



You’re the second user to report this. It works here - does it work for anyone else?


All okay with version 7.2.

FYI it did crash on first install


Steve Warby


We’ve seen that crash as well. The app has changed from being unsigned to having full Apple level security signing. We think that crash has to do with the OS coping with this change.
