I do not have El Capitan available to test right now. Which permissions are set on this file? Please show me the output of this command:

ls -lad /Applications/Xcode.app/Contents/Developer/Library/PrivateFrameworks/CoreSimulator.framework/Versions/A/XPCServices/com.apple.CoreSimulator.CoreSimulatorService.xpc

For reference, this is the output on my OS X 10.10 Yosemite.

drwxrwxr-x  3 root  wheel  102 Oct  2 23:11 /Applications/Xcode.app/Contents/Developer/Library/PrivateFrameworks/CoreSimulator.framework/Versions/A/XPCServices/com.apple.CoreSimulator.CoreSimulatorService.xpc/

This is actually against the requirements mentioned in the log above. Did you upgrade your Xcode and Command Line Tools to the latest version?

$ sw_vers
ProductName:	Mac OS X
ProductVersion:	10.10.5
BuildVersion:	14F1021
$ xcodebuild -version

FYI, I'm having the same issue on Yosemite 10.10.5 with Xcode 7.2

> sw_vers
ProductName:	Mac OS X
ProductVersion:	10.10.5
BuildVersion:	14F1021
> xcodebuild -version
Xcode 7.2
Build version 7C68

The output of:

> ls -lad /Applications/Xcode.app/Contents/Developer/Library/PrivateFrameworks/CoreSimulator.framework/Versions/A/XPCServices/com.apple.CoreSimulator.CoreSimulatorService.xpc
drwxrwxr-x  3 root  wheel  102 Nov 10 05:21 /Applications/Xcode.app/Contents/Developer/Library/PrivateFrameworks/CoreSimulator.framework/Versions/A/XPCServices/com.apple.CoreSimulator.CoreSimulatorService.xpc/

which seems to match your output.

Against my better judgement, I ran:

sudo chmod 755 /Applications/Xcode.app/Contents/Developer/Library/PrivateFrameworks/CoreSimulator.framework/Versions/A/XPCServices/com.apple.CoreSimulator.CoreSimulatorService.xpc

And the build now succeeds. This seems like more than just a problem with the MacVim build, though.

This really beats me... How can a stricter access on the catalog allow to build MacVim? Shouldn't it be the opposite? I tested on my own computer too and it worked,- but it does not make sense to me.

[raimue (Rainer Müller)]

I was able to reproduce the problem and the workaround also worked for me. Apparently it is an additional security check in Xcode 7.2 that checks the permissions on CoreSimulatorService.xpc and errors out if they are not strict enough. I doubt this is actually needed for building MacVim, but Xcode 7.2 wants this check to be satisfied.

This is now also documented in the ProblemHotlist. Since this is not a problem specific to MacVim only, I am closing this ticket.

For others hitting this, this resolved the issue for me as well.
