People frequently make/make install to "/bin" and "/sbin". The real problem is the no write access to /bin and /sbin. I agree it wont effect *most* bioinformaticians, but it will affect some - and those that it does effect will be effected hard, with error messages not at all related to the issue (as per the second link). To quote Apple's website "This will only effect you if your application integrates with the operating system". It won't be able to attach to system process like Finder, etc, but will still work for most things coming out of the world of Bioinformatics. Good news about self-signing, I will definitely try that out! :)Īnd you're right about lldb, I should have mentioned that it will still work for non-SIP protected apps. It seems updating xcode and reinstalling python fixes everything: Yes, HomeBrew installs things in /usr/local, but there have been a number of people who after switching have experienced problems, mainly because they are using old versions of Xcode. Thats good to hear Alex - I certainly hope that is the case! I am hoping that in the next few days we WONT see a huge number of complaints about xyz software no longer working, but to be on the safe-side I suggest sticking to OSX 10.10 until you know your pipeline will work on 10.11 :) It's now back in El Capitan, as a program called Trimforce, but you have to turn it on manually and accept the waiver that the SSD might become corrupt, although there's a pretty tiny chance that this will happen if its a new TRIM-compatible SSD. TRIM makes your SSD last a lot longer, and perform about 5x faster. A whole bunch of python modules (e.g., lxml)Īlso, unrelated to System Integrity Protection, anyone using a non-Apple SSD may remember that Yosemite prevented TRIM support by 3rd party apps.lldb (popular debugger that ships with OSX now can only attach to non-protected processes).SuperDuper (restored backups will have SIP turned off).Nevertheless, Totalfinder does not start, I still get the message from Apple events. TotalTerminal, TotalFinder and TotalSpaces I installed beta version 1.13.4, deactivated SIP and also followed the message sudo killall -KILL appleeventsd.I have no idea which bioinformatic software, if any, use such low-level interaction with the OSX kernel, but certainly the following applications you might currently be using will no longer work: Apparently this only affects "restricted processes" but from what I've tested this seems to be everything. For example, any scripts you use that make use of DTrace (Apple-made like iosnoop, or 3rd party like the workflow logger I just upgraded to make use of DTrace -_- ) will no longer work. These paths include:Īny files not part of Apple's core system will be moved out of these locations, although I'm currently not sure where too (probably /usr/local).Īny hardcoded paths or software you have installed in these system paths will obviously cease to work.Īlso, any tools not cryptographically signed by Apple via the AppStore (which is pretty much all bioinformatic software for OSX) will no longer be able to interact in certain low-level ways with the kernel. Although it doesn't remove the root account per se, it will prevent all users (including root) from modifying or writing to system paths and files. System/Library/PrivateFrameworks/amework/OverrideBundle.Tomorrow Apple will release it's version 10.11 of OSX called "El Capitan".Īlthough not a whole lot is changing on the outside, there is one big (and often unreported) change that will affect 'power users' like bioinformaticians, and that's the introduction of "System Integrity Protection" or SIP. I would reconsider implementing it if there was a sane way how to circumvent SIP in Finder injection case. Even if this is still the case under Big Sur, it seems with Signed System Volume filesystem-level modification of anything under /System will be a royal pain in the ass… Maybe Apple had a reason to not check for the signatures, so they could not easily fix it. If I remember correctly, XtraFinder relies on the fact that FileProvider framework loads extra “plugins” from this location without checking for apple/platform signatures. Library Validation: the Finder binary is newly marked as a platform binary, so system prevents loading/injecting any non-platform code into it even with SIP fully disabled, see how to disable it here: macOS Big Sur and TotalFinder. I wonder if XtraFinder will be able to pull this off again under macOS 11 (Big Sur).ĪFAICT there are two new security hardenings in Big Sur related to our case:
