Tried to launch Firefox Developer Edition installed from firefox-38.0a2.en-US.mac.dmg. But with no success:
Any ideas?
UPDATE:
I managed to launch it with /Applications/FirefoxDeveloperEdition.app/Contents/MacOS/firefox --ProfileManager but it still repeats the issue while be launched by clicking on app icon.
The best solution is to try re-downloading it because the file is "damaged", so that's what you have to try to do, if not, try downloading it off another website.

I installed MagicDraw 190_sp3 on my mac but it couldn't be opened. When I try to open it shows the error that the developer couldn't be verified. Can anyone help me in this regard, please?
Is your macOS showing an error alert like below?
If so, your app is not signed and notarized.
If you’re certain that an app you want to install is from a trustworthy source and hasn’t been tampered with, you can temporarily override your Mac security settings to open it.
If you still want to open an app for which the developer cannot be verified, open System Preferences. Go to Security & Privacy. Make sure Allowed apps downloaded from is set to App Store and identified developers. Click the Open Anyway button in the General pane to confirm your intent to open or install the app.
The warning prompt reappears, and if you're absolutely sure you want to open the app anyway, you can click Open.
The app is now saved as an exception to your security settings, and you can open it in the future by double-clicking it, just as you can any authorized app.
See this KB from apple for details
Thanks for your answer kakaiikaka.
I did all of those steps but it was still showing the problem, then I found out the problem was with my JDK version on my JVM. So, I installed JDK version 8 and again tried to open this and it worked as a charm!
I have a macbook air and I went to the store to install Xcode 7.3 and hit the update App button, and a loading icon appeared but after waiting 30 min time nothing happened. I successfully installed simple recorder from the store but I can't install Xcode.
What can i do?
What are the options to download it?
Try restarting your computer to see if Xcode has installed. This will also refresh the app store, so try downloading it again.
If all else fails:
You should uninstall all current versions of Xcode on your Mac. Do this by dragging each application to the Trash can. Delete your trash.
After, try downloading Xcode again and everything should go through.
You aren't aloud to download old versions of Xcode from the App Store.
I suggest you to download the new XCode 8. It works just fine, even if your update button doesn't seem to work. Need to use the App Store. Also, if you happen to be a React Native developer, you may want to follow this article just after having installed this new XCode version.
If you simply cannot install the latest version, I suggest going to www.developer.apple.com and click the Develop Tab, Xcode, Download, sign in with your apple id, and get an Xcode beta version.
www.developer.apple.com -> Login -> Account -> Downloads
If only spinner is showing, without progress. Open Activity monitor and check if installd is running and using a lot of memory. Try killing that process and update again.
This is on OS X Yosemite. It appears when I try launching Xcode.
There are no updates shown in the App Store and there are no active downloading updates shown, either. Not exactly the pinnacle of Apple's great user experiences.
I hope I don't have to do a clean install…
This happened to me during the installation of iTunes 12.2.1 (1220C173).
I restarted my computer and ended the update, then Xcode opened properly.
Happened to me as well. Restarting the computer fixed it.
Restart fixed mine too - after restarting, it asked me if I wanted to install some required components, and once that was done it worked fine.
Opening Xcode from the App Store fixed this issue for me.
Looking at the screenshot it seems a weird error. I don't think there will be a easy solution for this error. You have to go through the hard way.
Update/Install xcode again. If it didn't then
Update iTunes and launch/download Xcode again. If it didn't then
Update your Mac OS and try the above
P.S: I usually download xcode from here rather than from Appstore( requires Apple ID to login) https://developer.apple.com/downloads/
In my case I attempted to download Xcode 6.4 from the AppStore and got this same message AND the AppStore progress indicator was stuck; I couldn't pause the download because the button was grayed out. I rebooted and restarted the download a few times to no avail. But then I decided to wait and let the thing work itself out, and it did. Aparently there is a bug in the AppStore download for Xcode 6.4 that DOES download it (and it took forever in my slow connection) but does not show a progress bar. When I opened the Activity Monitor's Network tab, there it was!
Since I installed the last Mac OS update (Mac OS X 10.8.3), auto reloading stopped working in Play 2.1.0. When I change a file and save it, the file is compiled (when running with ~run) but when I hit reload on my web browser (already tried with Chrome and Safari) Play Framework don't reload the page. I already tried clean, clean all, reboot my Mac, but nothing resolved the problem.
Do you have any solution for this?
Thank you,
Filipe
I have the same problem with play 2.1.0 and I think it has to do with Jnotify
I have MAC OS 10.7.3. xcode 4.3.1 installed using different apple id as my macbook pro was used previously by my friend. Now when i try to upgrade Xcode to 4.3.2 it asking credentials for my friends account. Unfortunately App store clearly says you can upgrade an app using the account which was used to install the app.
How can i upgrade Xcode using my credentials?
Thanks in advance.
I am sure you would have solved this by now but just posting the solution here that worked for me..
Open Finder and navigate to Applications,
Ctrl+Click the application and choose "Show Package Contents" (Xcode in this case),
Expand the Contents directory and click the _MASReceipt directory to select it, Type Command+Delete to
delete the directory permanently---you will be prompted for your
credentials since this is a protected file.
Quit and restart
AppStore, then find the application. You can update with your new id now without deleting the old version of the app
Hope this helps someone coz it took me a while to figure out !!
Unfortunately had to answer my own question,
Simple Answer: NO, You cannot update xcode installed from another account.
Solution is to delete the existing installation and re-installing from new account.
To delete the existing installation, you need to delete it from Launch pad. You can do this by locating xcode icon in launch pad, long click on the icon till it starts dancing. Then delete it and wait for a while till the xcode.app is deleted from /Application. If you manually delete xcode.app from /Application, App store will continue to think its installed and will not allow you to reinstall in future.
Above solution is assuming you have installed xcode from the mac app store, usually versions later than 4.2. For earlier versions, just deleting /Application/xcode folder should work.
The solution is found:
I had this bug, it's related to Spotlight. The App Store used Spotlight in some way. My fix was to add the entire HD to the "Privacy" tab in the Spotlight System prefs pane, close the prefs and wait 30 seconds, re-open and remove your HD from the Privacy tab. Spolight begins reindexing. Re-opened the App Store and problem was fixed! Posting this here for others who might search later on. Also filed a bug report with Apple.
