Xfence and MacOS Mojave - reported crashes


Hi XFence devs, I'm running XFence 1.8.88 and MacOS Mojave 18A391 and noticed a repeated amount of OS crashes since 2 days ago (approx 10-15+ crashes). Here is a sample panic report if it can provide any help. Thank you!

    I reported this as a bug in the beta program. I recommend you do the same as well. I really want to see this fixed ASAP. Being without XFENCE after having it since the Flocker days makes me nervous now that I'm used to that layer of protection.

  • darkkavenger

    I have yet to do this (very busy and juggling with a ton of things) but wonder if it can't be related to how Mojave handles disk permissions. Backblaze for example asked users to do a mandatory upgrade and to explicitly grant full disk access permissions to their app: https://help.backblaze.com/hc/en-us/articles/360009644134-Upgrading-to-Mojave-Read-This-First-

    Allright, reported as a bug.

  • matijak
    matijak Posts: 4 New Member

    I've also reported it as bug/critical incompatibility a couple of days ago.


    However, I strongly believe that XFence is dead as Mr. Zdziarski is now working at Apple and regardles of the fact that F-Secure bought it from him to gain access to it's technologies to be able to implement them into their endpoint sec. products, Apple is "replaceing" XFence's features balanced with usability (and of course, because of that with significant limitations) built into the latest v. of macOS.

    Same crashes here. I've also submitted the bug report in the beta program but I also think this project is dead.

  • darkkavenger
    darkkavenger Posts: 4 New Member

    I came to the same conclusion as you and @matijak. I did report the bug, but there has been no new version released, and seeing the implementation of a function (albeit still very basic) in iOS Mojave about permissions for full disk access, combined with the hiring of the original Little Flocker dev, is a sign of things to come.


    The crashes have continued unabashed; even when disabling XFence I had some reboots where it was enabled again. I ultimately had to remove XFence as this was starting to hurt my productivity in a bad way. I'm concerned I don't have this protection layer anymore, but I've got work to do.

    Apple has indeed implemented features with (limited) user control accessible under Settings>Privacy.


    They’ve implemented app protecting features available to developers as well. F-Secure has to consider using it instead of relaing on their own technologies to avoid such incompatibility issues afer upgrades have been made in production environments.

    I get similar crashes, but in my case it's invariably "BSD process name corresponding to current thread: xpcproxy"

    Having the same problem here.
    - macOS 10.14 (18A391)
    - kernel: Darwin 18.0.0
    - XFence 1.8.88

    Whenever Mojave crashes it reports XFence Kernel extension in the backtrace section of the panic report.

    Same problem. Upgraded to Mojave, repeated random crashes. Followed the breadcrumbs & figured out XFence was responsible, disabled it. No more crashes! Is XFence really an orphan?

    Sorry for the long quiet period on the Xfence front. We concentrated our team effort on the Mojave release and are currently working on a small maintenance release for SAFE MAC. After that we will take a look at the Xfence beta and hopefully solve the crash issues on it.

    I'm really glad to hear XFENCE has not been forgotten. Are there any unofficial (and totally non-committal) ETAs on XFENCE getting some attention?


  • KimArden

    +1 Crashing in a few seconds of logging in if XFence is enabled.


    XFence  1.8.88

    macos 10.14


    For whatever reason, my second Admin account on this mac does not crash. That's an account I only log in to  do high-level admin things, and that account seems to run fine.

  • Cale

    If the issues are solvable with reasonable effort, we plan to release a new version before end of year.



  • KimArden
    KimArden Posts: 2 New Member

    UPDATE: My seldom-used admin account also became effected, so I had to:


    - Restart in Safe Mode, then

    - Remove the kernel from Library/Extensions


    I'll await that update.

    Such unrealiable development cycle management and unresponsive support are determining project’s feature; I see no light at the end ... And on the other hand, Apple integrated  it’s functionalities into the latest macOS.

    I have same issue - but my MacBook pro will crash *every time* after system start-up.

    On my case, the issue started with me enabling the XFENCE on Computer Protection for Mac version 17.2. On macOS 10.13 High Sierra.
    As I was unable to use my computer, I restored the system from Time Machine backup.

    Then shortly afterwards, a notification of update for Computer Protection for Mac started to pop up.
    Once I installed the update, the crash returned - without me enabling the XFENCE! (The crashes were accompanied with multiple XFENCE dialogs where various [apparently] system components requested access to various system files.)

    The same issue persisted after updating the macOS to 10.14 Mojave, as well as the latest OS update 10.14.1.

    A support case has been created. I was instructed by F-Secure support specialist to remove the XFENCE.kext in Single User Mode, after updating the Computer Protection.

    I did that, but it DID NOT clear this problem. Computer Protection for Mac updated from version 17.2 to the current one, with XFENCE.kext deleted from /Library/Extensions, still causes my Mac to crash right after start-up, before login.
    Full system restore from Time Machine, restoring the Computer Protection to version 17.2, is the only way out.

    Integrated into the latest macOS?  Only a small subset, to be sure.  I really want to have XFence back up and running.  Without it, I lose a ton of security.


    I wish they'd release a supported version of it already.  I'm happy to plunk down cold hard cash to keep this running on my machine.

  • Toweri
    Toweri Posts: 20 Enthusiast

    And to reply myself: I found a solution. It is presented in my post under another topic .
    I'll repeat it here for your convenience:
    I have found a tested and working solution for those, who cannot remove XFENCE.kext from /Library/StagedExtensions/Library/Extensions/ - even via Single User mode:

    Delete the actual kext from /Library/Extensions/ first, then run "KextWizard" (downloadable at https://mac.softpedia.com/get/Utilities/Kext-Wizard.shtml) and enable both checkmarks under "System/Library/Extension, i.e. "Repair permission" and Rebuild cache" - then click "Execute".

    This removes the stubborn XFENCE.kext from the cache (that /Library/StagedExtensions/Library/Extensions/ actually is) and keeps it from being activated over and over again.
