    Re: Tech Update: Update: Reboot issue affecting Apple Mac Pro devices

    Thanks for all the updates. Obviously we now know Chrome caused the issue. However please could we have some clarity on why this appears to have particularly affected systems which had Media Composer installed too.

    Chrome has a huge install base, so what was it about the system makeup that in some cases meant Chrome + Media Composer = potential problem? Has Media Composer or IO hardware drivers been altering SIP settings in the past? Would be good to understand this side of it, if indeed there is anything.

    Clearly the faulty update from Google which KO'ed peoples system is not Avid's fault, but I think its fair to say there is more to this than just saying 'it was Chrome'.

    If it was just all a conincidence, then OK great.

    Re: Tech Update: Update: Reboot issue affecting Apple Mac Pro devices

    It's not Chrome in particular, it's Google Auto-update which works across their products. So you might not use Chrome but if you use Calendar or other you were potenlially in trouble.

    There is also a lot of BlackMagic "victims", but they are less vocal than Avid users - and don't have the same effect on Variety and similar media outlets. What's in common is that all were using machines with SIP deactivated.

    Why would you disable SIP? Because you're running third party hardware (most likely a more beefy GPU) which requires drivers that are not blessed by Apple. Or you're using modified system extensions that let you use the full potential of your GPU - as the stock extensions from Apple are castrating your hardware. Or because you're using an eGPU and again, you have to use modified extensions because what Apple provides is half-baked.

    Go it, thanks. Kind of surprising that anyone operating a high end cutting room would use essentially cobbled together kexts for eGPUs on a MacPro, but guess it was all good until this.

    Me too. But when you see that a RX580, a gpu offcially blessed by Apple doesn't have hardware acceleration enabled and that hacking one kext enables it, allowing for 4 times faster H264 encodes, real time HEVC decode and so on, it's quite tempting to disable SIP...

    If it was just all a conincidence, then OK great.

    Mark et al....   It was prodominantly seen in LA but also across the globe but the variety peice jumping the gun caused more emotional dialog in LA.  

    It would occur on any Mac with or with MC, PT, Adobe etc... if the Mac was 10.11 and higher and the SIP ( Security Interface Protection) was turned off. It could also occur on a pre 10.11 Mac as 10.10 and earlier didnt have SIP.  

    Many Mac users in the editing field try to gleen as much use out of their Mac's and as such, when the OS is updated, a driver or something like TB doesnt work well.  They disable SIP, install the "driver(s) needed, and then dont enable SIP back.

    The prefect storm was a chrome keystone update that had a bug which was able to get thro9ugh those systems with SIP diabled.  Thus causing the reboot cycle.  Not until the Mac was booted in safe mode / recovery mode and the OS installed over the existing, did the Mac return to function.

    MC doesnt alert the SIP.  MC Installers dont alert the SIP.   Avid doesnt recommend that SIP be diabled.  

    For 3rd Party GPU drivers, those companies are saying that the user would need to disable SIP to install the driver, but then should be able to re-enable SIP after install to work with the GPU.

    Another rumor......   Avid export to desktop requires SIP be disabled.   FALSE!!!!!  

    Avid export to the desktop does NOT require disabling SIP.

    It was Chrome with the bug's fault Marc in that the bug is what started the whole thing but the SIP being disabled by the users themselves was also part of the perfect storm  as Mac's and OS comes with SIP enabled and Avid DOES not do anything to the SIP at all.

    True but enabling SIP is also a must after the hacking takes place :)

    Thats what happens when people want to get the most out of their hardware - so they fiddle and diddle to make it work.  Also cards like some NVIDIAs dont work - Apple wont qual them... so it becomes a pissing contest and the way around it for a user is to disable SIP and use the stuff anyway.

    Just got to remeber to turn it back on.   

    Another common scanario.... cloning to update many many systems.  If the cloned drive has SIP off, the units upgaded end up that way. Had a sight with 85 down and that was why.... chrome keystone update, SIP disables and 10.12.6.

    Perfect Storm

    This is not true. On 10.13.4 with MC 2018.5,  I have personally had to disable SIP, then adjust permissons on the internal hard drive, to get AAF's to export to the desktop. It might be fixed now in recent OS's but I 100% have had to do this.

    Also, on OS's 10.14.5 and 10.14.6, before 2019.8 Nexis client came out, I have had to disable SIP to get the Nexis to show up in the Nexis client manager.

    Was really unfortunate the way it went down. What a few days you guys must have had. Some consolation for figuring out it had nothing to do with Avid. Hampers incoming from Google I hope.

    No app, even Avid, should ever require SIP to be disabled especially to the desktop of the current user for basic functions. That is either a bug that should be reported or corruption on the OS side. I oversee hundreds of Avids and assist other clients with hundreds more, I never once heard this. If this was the solution, I would have definitely stopped using that version of MC or re-imaged the Mac.

    If the Nexis client is not the approved version, disabling SIP to force it to work would be a risk the user has taken on.
