It's actually very easy.... Using Terminal Type the following command: rm -rf /Applications/Install\ OS\ X\ El\ Capitan.app/ This will remove the the install and sub-folders for the El Capitan installer. Using Finder Open the Applications Folder by navigating to it or by pressing ShiftCommandA. Select the Install OS X App and Control Click or right ...

I reviewed /private/var/log/install.log to find the error and couldn't find one, so I removed it, and reran the install from the app store panel and it worked. Dunno what and if something else had changed.

Make sure your Mac OS is up to date. I was having these issues updating XCode and tried many of the solutions on SO, however, it took updating the operating system to fix the issue.

This can happen with any app if you have formerly downloaded the same app (i.e. With the same internal "bundle id") from outside the App Store. Simply move the app to the Trash, restart the App Store app and try downloading the app again. Trashing an app does never make you lose your settings or even project. This is not Windows (where Uninstallers are ...

I had the exact same issue. The culprit, in my case, was that I had older versions of the installer in other locations on my drive. The solution was to move all older versions to the Trash and reboot. I did not empty the Trash, however (just in case). Upon rebooting, the App Store behaved and I was able to re-download the complete OS 10.11.4 installer. Then ...

It looks like you've done more than the expected basic troubleshooting (reboot, try debug mode, single user, try the same AppleID from a new user account) and you're looking at either a cascading failure (multiple caches or multiple keychains with bad signing data) or some lower system level failure in the code signing / update / permissions. If you bring a ...

You can't easily interrupt the download or the check for enough space with a toggle or a setting. Much easier would be to use a second drive to add capacity. If you don't like moving files off the SSD, just install OS X onto the external drive and keep space there for overflow files and new app downloads. A 32 GB SD card or fast thumb drive would let you ...

Ran into the same issue today when updating XCode: storedownloadd pegs a CPU core for 20 minutes. I tried breaking into storedownloadd with a debugger and I see some incredibly long stack traces and a lot of time spent inside Security::CodeSigning. I suspect that it is recursively verifying the digital signatures of a lot of tiny files one-by-one. I have ...

Yes I always found updating XCode from the AppStore a painful experience. Assuming you have a developer account, use this link and then find the version of XCode you need.

Just restarted the machine and that solved the issue. Now it's downloading.

If I wanted to troubleshoot this - I would do the following: Make a new admin account on the Mac and restart. Log in to the new account (you might have to disable auto login for the old account) Open Console.app and look over two log files /var/log/install.log /var/log/commerce.log Open System Preferences (while watching the logs above) and unselect all ...
