I am having this same issue, but I am running on Windows 7.
Animations worked fine on 4.3 and even in earlier versions of 4.4. I upgrade to 4.4.2 today and character animations do not loop properly and “pop” at end of their animation. I’ve tried making a new project and it still exists there as well.
Hey MooseCommander,
It’s likely issue you are experiencing is a separate issue, as these seem to revolve around a specific version of Mac OS. Please open a new post in Bug Reports section for your issue with as much detail as you can provide. You can check this link on how to report a bug:
Thanks!
Today I tested new Yosemite Public Beta 3 and UE 4.4.3.
Still got problems with animation.
I’m uncertain on how to check version of nvidia drivers but I tried this in a terminal app.
kextstat | grep NV
36 0 0xffffff7f82d2b000 0xb000 0xb000 com.apple.driver.AppleEFINVRAM (2.0) <33 7 6 5 4 3 1>
111 2 0xffffff7f811f4000 0x276000 0x276000 com.apple.nvidia.driver.NVDAResman (10.0.0) <90 82 79 12 5 4 3 1>
112 0 0xffffff7f81475000 0x1ae000 0x1ae000 com.apple.nvidia.driver.NVDAGK100Hal (10.0.0) <111 12 4 3>
I do not have opportunity to do same on Mac OS X 10.9 to do comparison.
I can confirm that this issue is not occurring in 4.4.3 on 10.9.
This is now something Nvidia and Apple need to work on, and we’ve reported issue to them. Thanks for continued updates!
I just thought that I would report status of this problem.
I have now tested with OS X Yosemite 10.10 Final version and UE4.5 and problem is still there.
It works perfect in UE4.3 with same OS.
It also works perfect if i switch to Intel Iris graphics card.
I hope nvidia and apple soon fixes this.
Can I report this somewhere?
Hey ,
This is best place to post for now, so we can track it all in same place. Thanks for update!
We have a workaround, which you can download from here: https://s3.amazonaws.com/unrealengine/qfe/QFE-FromCL-2326468-Shelve-2331902_Mac. (92 MB) Just unpack file and run patch installer. It will also be included in UE 4.5.1.
Thats fantastic news!
Nothing is happening when I double click patch though…
I get this error when I run it from Terminal:
sh-3.2# ./QFE-FromCL-2326468-Shelve-2331902.app/Contents/MacOS/UnrealQFEInstaller
2014-10-20 17:50:47.370 UnrealQFEInstaller[1997:303163] Unable to load nib file: MainMenu, exiting
sh-3.2#
Any ideas?
Sorry, app does nothing when I launch it.
hi nexus
i have exactly same problem with a brand new i just purchased for UE4, workaround did nothing for me too.
Please post if you resolve this issue.
Cheers
I did above. But stil do not work.
I run it from Terminal.
That brings a dialog with a start button.
After I patch it. UE4.5 do not start at all.
Any ideas?
This is what it says from terminal
sh-3.2# ./QFE-FromCL-2326468-Shelve-2331902.app/Contents/MacOS/UnrealQFEInstaller
2014-10-21 19:57:04.467 UnrealQFEInstaller[3685:525650] Failed to connect (StartWindow) outlet from (AppDelegate) to (NSWindow): missing setter or instance variable
sh-3.2#
Hmm. No idea how did this happen, but patch is missing a file. Sorry about that!
I will prepare a fixed , but in a meantime, if you don’t want to wait:
Please unzip attached Base.lproj., then right click on QFE-FromCL-2326468-Shelve-2331902.app, select Show Package Contents and move unzipped Base.lproj folder to Contents/Resources in there.
No idea what can be wrong, sorry 
Could you please wait a bit and try downloading fixed patch again once I let you know it’s uploaded, hopefully that’ll work. Should be ready very soon.
Ok. Just let me know when to try new fix 
Fair enough
Thanks for (probably) fixing bug.
It turned out that 4.5.1 will be released tomorrow and this fix will be included. Many thanks for your patience and sorry again for trouble with non-working patch.
Wow…! 드디어 ㅠㅠ
I’ve been waiting very long long time!!
Thanks mike :=(
Its working now!
4.5.1 did trick.
Its working both on my MBP and iMac.
Good work!
hi Nexuz how did you get 4.5.1? i don’t see it in my launcher
