  • MacBook Pro crashes when I connect ANY monitor! Help!

    I’ve been working in AE for years but now I’m in a situation that I can’t seem to find my way out of. After Effects works fine until I click on a subcomp. Then the wheel and that’s it. It doesn’t seem to happen when I work in other programs, which I don’t do that much. As soon as I add a monitor, 2k, 4k, portable monitor or even iPad Pro it happens. I have 3 months of deadlines coming up and I’m at a loss. I’m working on a MacBookpro 15″ 2019, 2.6 Ghz 6 core intel Core i7 with 32 GB ram, Radeon Pro 560x 4 GB. I also have an older macpro (garbage can) with 60 GB ram, same problem. I have cleaned off both computers and reinstalled everything. I am running BigSur version 11.4. Suggestions? I would be grateful for any help. I have called Apple, Adobe, both point to each other.

    Hope its not Big Sur for starters since its a PITA to roll back.

    How are you connecting the displays?

    What kind have you tried?

    And its just when you connect external displays?

    What about resolution?

    yep, Big Sur… I just purchased a refurbished LG ultrafine monitor so I hope it will be more compatible, the 4k with thunderbolt 3 connectors. My other monitor is in the shop checking to see if there is any problem with it. It’s an LG 27UK850-W 27″ 4k UHD IPS monitor. I connected it with the cables it came with (tried them all). I think I settled on usb-c. I also bought a dock and tried to connect peripherals to that. It only happens when I connect external displays. The projects are 4k. I’m not sure about mixing 2k and 4k. I was using a Dell monitor which used to work fine with my old macpro. I’m pretty sure I also bought a cable that was supposed to work with 4k monitors.

    I have a 2019 MacBook Pro and had this issue last week. For me it was a standard HDMI cable that was the problem.

    Some cables are suspect but not enough to crash a system.

    Just to add I work on a ton of 4K to 8K projects on an Apple Cinema 30″.

    So no need to be forced into a 4K display if cost is an issue.

    I have Big Sur running on a 2013 Mac Pro D700 at home and so far so good.
    I sure hope you get that going.

    I used an Apple Cinema Display for years until it died. That’s when some of the trouble started. I have a Dell monitor 2k that has been fine on my older macpro system which has been more stable then the macbookpro. When I have tried to add a 4k monitor I had problems. We’ll see if my laptop works with the LG ultrafine when it arrives. I don’t think the 4k monitor that’s in the shop will work with my older machine…

    The Cinema res is a lot lower than a 4K display.
    I am hoping it’s not your laptop/Big Sur combo causing the crash.

    I have never experienced a hard crash by connecting displays.

    Glitches and screen tears but not a hard crash.

    But the in my years I have ran into bad (even brand new) cables 😛
