Just upgraded. Can't delete apps. Anyone figured this out yet? Admin accound sudo rm -rf "game center.app" is returning operation not permitted. Appcleaner is not even able to find the packkages much less delete them. I have the GM though. What is this about? Edit: upgrading to the appstore version. Not sure if this was GM specific, or they are locking the Os down even more. Edit2: if you forget your password immeadiately and use the resetpassword feature in terminal, keychain breaks, can't find "login". Prob fix it with permissions. Note, NOT the case. Had to make an entire new user. Also, with >30mbps connection, 850mb upgrade is taking ~4hrs. They must be getting slammed. Edit : Boot args didnt fix. Trying carutul disable at recovery terminal. Bash-3.2# csrutil diasable Seems to work. Edit n: seperate and unrelated, system does not seem to restart well. Eiter hangs or takes ages.

That’s probably because of System Integrity Protection. It can be disabled though: https://en.wikipedia.org/wiki/System_Integrity_Protection https://en.wikipedia.org/wiki/System_Integrity_Protection

Might be related to Rootless? "OS X adds a new feature called "Rootless" that keeps the root user found on Unix-based systems from being able to be run. This can cause some troubles for disk management and backup utilities, so they included a way to turn it off. Open the Terminal and type sudo nvram boot-args="kext-dev-mode=1 rootless=0";sudo reboot to disable rootless and reboot your Mac. Only disable rootless if you know what this feature is used for, and you are experienced with the OS X command line."

That’s System Integrity Protection. Under it, system files cannot be deleted or modified, even with sudo. It protects down to the block level, so even if you try to bypass the file system and write to blocks composing system files directly you’ll get an error. This can be disabled but I wouldn’t advise doing so unless you have a really good reason to.

  Modifying /usr isn't THAT unusual.

    The FHS defines /usr thus[0]: > /usr is shareable, read-only data. That means that /usr should be shareable between various FHS-compliant hosts and must not be written to. Pretty much all modern unices consider that /usr, aside from /usr/local (which the FHS defines as "for use by the system administrator when installing software locally. It needs to be safe from being overwritten when the system software is updated."[1]), is part of the operating system. It is thus very much unusual to modify /usr[2], and in line with current practices to lock it down tightly. /usr/local is not under SIP.

      The FHS is, at best, only tangentially related to anything going on in a Mac OS X system.

Thanks for bringing this up, I just cancelled my download. There is no way I'm going to run an OS that attempts to limit my power to delete or modify applications. I think this may be the final straw for me and OSX. I very recently had to attack GarageBand with a hex editor to disable app sandboxing so I could use third party VST plugins. I realize System Integrity Protection can be disabled by a kernel boot param, but this really, really, sticks in my craw.

  You already couldn't modify most system applications or they would fail code-signing checks. This is merely preventing malware from modifying them.
  - spudlyo 11y ago
    By that logic malware presumably couldn't modify them either, right?
- aeontech 11y ago
  You can delete and modify non-system apps just fine, FWIW. I imagine Game Center.app is not locked down for some nefarious reason, but just because it falls under "system owned" list.
  - spudlyo 11y ago
    I think GarageBand also ships with the OS (or at least it used to) so I wouldn't be surprised if it's also on the "system owned" list. This pushes all my security vs. liberty buttons.

      I just did a wipe and clean install and it does not install GarageBand.
- tim333 11y ago
  It's not hard to disable. Restart holding down command R to get recovery mode, launch the terminal, type "csrutil disable". Sorted.

Why do you want to delete Game Center?
- brianstorms 11y ago
  Game Center is a nasty piece of work by Apple. It's ruined iOS 9 and I regret installing that on my iPad and iPhone 6. Now, when I enter a very simple solitaire-like game called Midnight Mahjongg, I get slow-animating, built-in-delayed GC upsells and requests to log in to GC, even though I hate and detest and loathe GC. And if I so much as accidentally go to Home screen and back into game, presto, GC upsell appears again. On iPad it appears for 5 times -- you have to cancel 5 times and then it gets quiet. Until the next day. On iPhone, 3 cancels is enough to shut it up. Until the next day. Use the game the next day and the counters are reset: 5 more cancels on iPad, 3 cancels on iPhone. GC is the worst thing Apple's done in years. And if they have brought that crap and its fascist ways to MacOSX, then I really am hesitant to install any more MacOSX updates.

    Why not just sign into Game Center? It's a serious question. Once you enable Game Center it stops bothering you and as far as I can tell doesn't really do anything other than add you to leaderboards.

  Because they're about principle and can't stand losing that few megabytes of space on an app they'll never run anyway.

"Edit n: seperate and unrelated, system does not seem to restart well. Eiter hangs or takes ages." This is nothing new for OS X. Mavericks and the last couple of versions cannot restart / shut down properly. I'm sure Apple would say it's a feature not a bug.
