    All Apple Mac users&fans get in this thread we share information about running UE4 on a Mac & MacOS

    Why should we talk about UE4 and Mac?
    1. We love UE4 (no doubt ~) -if not shut off this page.
    2. And we love Mac & MacOS (absolutely no doubt~) -if not just leave. enjoy your pc.
    3. But 2 lovely girl did not get along very well with each other, that's the problem !

    UE4 Saying:
    1. I can running on the MacOS
    2. But that's not my true love , my target platform is windows, So running on the MacOS should be getting lower performance on it.(I didn't know why and how exactly, it's complicated. If you want to tell us the detail please write below~)
    3. So if you want the same performance you need more from a Mac. Not my bad...find out my creator...

    Mac Saying:
    1. You know. My price higher, my price performance lower, and that thing (UE4) asking more performance... and you know, my GPUs cooling system... But after all, I'm elegant and you standing by my side.
    2. And you need me to build iOS apps. - don't tell me about the hackintosh or Virtual machine, it's tons of trouble and it is not elegant.
    3. And here is a good news now ! AMD is stand up finally ~ So let's talk about the performance you need. and the and peace.

    ---This is all the things I know---

    Back to the topic. Find out !

    How could UE4 running perfect on Mac & MacOS!

    Below is the official system requirement on the website.(But in my personal experience it's not enough for a Mac user.)


    Here are the latest Unreal Engine 4 system requirements:
    • Desktop PC or Mac.
    • Windows 7 64-bit or Mac OS X 10.9.2 or later.
    • Quad-core Intel or AMD processor, 2.5 GHz or faster.
    • NVIDIA GeForce 470 GTX or AMD Radeon 6870 HD series card or higher.
    • 8 GB RAM.


    Let make a list, for mac user reference:
    (and I need you guys to share information to improve this list.)
    • New Mac Pro 2019 = Absolutely Yes -the price...

    Yes, certainly. It is an over kill. Unless you could afford the price. and don't tell me if you have the pro stand too.
    • iMac Pro = Yes -the best price performance?

    iMac Pro "10-Core" 3.0 27-Inch (5K, Late 2017)3.0 GHz 10-Core Xeon W-2150B* 5302 35620
    iMac Pro "14-Core" 2.5 27-Inch (5K, Late 2017)2.5 GHz 14-Core Xeon W-2170B* 5169 40974
    iMac Pro "18-Core" 2.3 27-Inch (5K, Late 2017)2.3 GHz 18-Core Xeon W-2191B* 5156 47221
    1. Yes, With Vega 56 / Vega 64 / Vega 64X. I think all of them could running UE4 very well.
    2. But I want compare iMacPro to iMac-27 top-end find out the best price performance Mac for UE4.
    Let's talk about the CPU with UE4:
    iMacPro 3.0 GHz 10-Core Xeon W-2150B Geekbench 4 (SingleCore): 5302 (MultiCore): 35620
    iMacPro 2.3 GHz 18-Core Xeon W-2191B Geekbench 4 (SingleCore): 5156 (MultiCore): 47221
    iMac "Core i9" 3.6 27-Inch (5K, 2019)3.6 GHz Core i9 (I9-9900K) (SingleCore):6166 (MultiCore): 32200

    I didn't know which one is the best price performance for UE4 development. better single core or multi core ?

    I think it is depend on what kind of content you are working on. I am working on a AR/VR project so it is 3D scene and the scene scale is not too big, so it is a small 3D project. I prefer to the better single core, I think the 3.6 GHz iMac-27 is better for UE4 and it has a better price too. Tell me if I was wrong.
    • iMac = Yes&No

    iMac "Core i3" 3.6 21.5-Inch (4K, 2019)3.6 GHz Core i3 (I3-8100) 4611 13403
    iMac "Core i7" 3.2 21.5-Inch (4K, 2019)3.2 GHz Core i7 (I7-8700) 5855 27121
    iMac "Core i5" 3.0 27-Inch (5K, 2019)3.0 GHz Core i5 (I5-8500) 5203 20649
    iMac "Core i9" 3.6 27-Inch (5K, 2019)3.6 GHz Core i9 (I9-9900K) 6166 32200

    Now, Let's talk about the GPU with UE4:
    Official requirement shows the base line of GPU is AMD Radeon 6870 HD = Radeon Pro 555X(iMac-21.5 base line).

    But I think if you are working on a 3D project now, It's not enough.(I am not sure ~), if you are running UE4 on a iMac-21.5, tell me your experience.

    In my opinion, the whole 21.5 inch iMac is out of option.I think the graphics is not enough. And I only recommend Vega 48 in the top-end iMac-27.That's should be an no regret choice. But I still need more information about this.

    iMacPro or iMac27-top-end, which one has the best price performance for UE4 ?
    • MacBookPro = Yes/No? But still have hope.

    MacBook Pro "Core i7" 2.6 15" Touch/2018 Vega2.6 GHz Core i7 (I7-8850H) 5057 21264
    MacBook Pro "Core i9" 2.9 15" Touch/2018 Vega2.9 GHz Core i9 (I9-8950HK) 5334 22421
    MacBook Pro "Core i5" 2.4 13" Touch/20192.4 GHz Core i5 (I5-8279U) 4860 17890
    MacBook Pro "Core i7" 2.6 15" Touch/20192.6 GHz Core i7 (I7-9750H) 5324 23572
    MacBook Pro "Core i9" 2.3 15" Touch/2019 Vega2.3 GHz Core i9 (I9-9880H) 5451 28585
    MacBook Pro "Core i9" 2.4 15" Touch/2019 Vega2.4 GHz Core i9 (I9-9980HK) 5627 30196

    There is no doubt that you must to chose the best one if you want run UE4 on a MBP.

    Even you have a MBP-15-i9-Vega20-2019, you still need a pray, hope it is stronger and cooler enough to handling with your UE4 project.

    Question:Why do we need UE4 running on a MBP ?
    Answer: It is the only Portable option for mac!

    I need portable so I need MBP to run UE4. That's the beginning of this story.

    Compare to the iMac, I can accept the lower GPU to exchange the portable ability.If it could running UE4 well.

    I have a 2015-MBP-15inch, and I tried every thing to make it run UE4. even tried with a eGPU, failed.

    (by the way eGPU is not recommended because it is not stable and not fully supported by apple, not really fully.)

    I find out that the biggest issue prevent a MBP running for UE4 is the Heat. Both the CPU & GPU make too much heat (especially CPU), when UE4 is running, without doing anything just open the edit, the fans are already noisy (up to 4000 rpm),and the cpu temperature is reach 80 centigrade. And when you doing something it could reach 90 centigrade easily and the fans are crazy!

    What I tried:
    1. Optimized all the settings in the UE4, set it to lowest performance. Not too much help with cooling.
    2. Running UE4 on Boot Camp Windows 10, and hope it could reduce the cpu temperature. works but not enough.
    3. Turning off the CPU's Turbo boost, it works but still not cooler enough.
    4. Use eGPU to help reduce the cpu temperature, both in the MacOS and Win10, it works but not enough and eGPU is not support well in boot camp win10.
    5. Conclusion: give up my 2015-MBP-15inch to run UE4.

    ---that's my experience---

    How about the New MBP?

    Let's see this video on the youtube created by Xcreate(not me)
    Unreal Engine 4 for Windows vs MacOS | Which is Best for Game Dev?

    Unreal Engine 4 on MacBook Pro | 555X vs Vega 16 Performance

    Thanks for this Guy and he light up my hope again.

    After watch this video that I think the latest 2019-MBP-15-Vega20 may running UE4 well. And I begin to expect the next Navi MBP now.

    But after all it is still depend on what your project content is. So I still need more information to insure it. Tell me about your experience if you are Working on a latest MBP with UE4.

    We developers need it for long time running, not just a while. So it must be cooler enough and stable all the time.
    • MacMini = Err...No

    Mac mini "Core i3" 3.6 (Late 2018)3.6 GHz Core i3 (I3-8100B) 4671 13828
    Mac mini "Core i5" 3.0 (Late 2018)3.0 GHz Core i5 (I5-8500B) 5146 20126
    Mac mini "Core i7" 3.2 (Late 2018)3.2 GHz Core i7 (I7-8700B) 5653 24072

    Mac Mini is not recommend because it's weak GPU.

    And if you want use a eGPU with it to make a best price performance combination.The 20% eGPU performance lost var Thunderbolt 3 is not a big issue. The only thing you should really take care is the eGPU's stability. Tell me if you made it and feel well.
    • MacBook Air = No
    • MacBook = forget it.
    • iPadPro = Err...Yes, I hope UE5 should running on the ARM.

    That's all.

    Please share your experience for all Mac-UE4 developer.

    I hope this thread could collect and end all the periodic questions just like: May I running UE4 on my Mac xxx XxxX XxxXxxx ?
    And leading ppl right way to go.

      Here is a fully test on 2015-MBP-15inch to show why it could not run UE4 cooler enough.

      MBP:MacBook Pro "Core i7" 2.5 15" Mid-2015 (DG) i7 (I7-4980HQ) Geekbench 4 (SingleCore) 4088 (MultiCore)13965
      CPU: quad core base frequency 2.5Hz Turbo Boost 3.7Hz TDP:47W
      GPU:AMD Radeon R9 M370X 2 GB
      Record by iStat Menus.

      Running UE4 on MacOS with Turbo Boost turn off

      Why turn off Turbo Boost? Because if not most of MBP's CPU will got too hot to run UE4. Turn off is the only way to do this for now.(as I know). And yes it slow down the building time and launching time obviously.

      Base Situation = just open a blank project make a blueprint actor stay in event graph without doing anything

      Working Situation = doing everything

      CPU temperature Fans speed CPU Power CPU frequency
      Base 60-67 centergrade 4000 7-10W 1.7-2.0 Ghz
      Working 83-99 centergrade 6150(top) 35-60W 2.5 Ghz (locked)

      GPU is always keep 65-70 degrees Celsius. So it's not GPU's problem. Most Heat come from CPU.

      And even turn off CPU's Turbo Boost it still could ramp up to 60W power. That's the heat come form.

      There is a tool Volta could limit the Power from CPU. But it needs to modify System Integrity Protection. I'm not sure it is stable to use.

      And another test is done by Xcreate yestoday.

      He said: For me when I turn off Turbo Boost the editor still runs fine and the fans drop to their base level of 2k. The only thing I've noticed that's slower in this mode is compile times, so you can always toggle it depending on if you're doing that. In Windows my fans ramp up to 5950 during a compile, but if I turn off Turbo again they drop to silent.

      And His MBP: MacBook Pro "Core i7" 2.2 15" Touch/2018 2.2 GHz Core i7 (I7-8750H) 4915 21111
      CPU: six core base frequency 2.2Hz Turbo Boost 4.1Hz TDP:45W
      GPU:AMD Radeon Pro 555X

      Good new is this 2018 MPB could be drop to silent when turn off Turbo boost running UE4.

      So the conclusion is: it on the CPU. 2015-MBP even has 2.5GHz base frequency higher than 2018-MBP, But it is not a cooler CPU. Hot is the only issue prevent MBP run UE4. 2018-MBP's CPU is much cooler, it has a better Watt Performance, that's the key to run UE4 on a MBP.

        So we know How to choice a MBP for UE4 now = better Watt Performance = we need MBP better Performance and be cooler too

        Apple would update the hardware performance every generation without doubt.

        But would apple update the thermal performance ? That's the question, we need it to be cooler too !

        And you need an Expert to do the Fully-Test-Job for every new generation of MBP, and get that information.

        Thanks God give us Anthony and he did this fully test video today. God bless him.

        Now we know exactly the detail we want.

        Anthony !

        Keep doing this on the Next MBP Please.
