Hi,

What does the crash report says?
Also, You should consider installing Windows using Bootcamp as it is easier to compile in Windows 10 than Mac OS as Visual Studio has some small problems in Mac.

Hi,

The error listed in the crash report also appeared with previous versions of the engine on Macs. It was also patched with Hot fixes or newer versions of the engine. Do you experience this problem with the current version 4.26.2 or with an older version of the engine? If so, maybe you could wait to the newer version 4.27 or a hot fix of the current version and hopefully they will fix it.

I haven’t even go to the install part of UE4.

Well, a quick explanation to the error then. Basically the Launcher was trying to apply an update but failed to copy and overwrite the old version of the same file, that’s why the error is “Invalid attempt to access memory to address”

The solution is the same, you will have to wait for an update that fixes the problem or you could try uninstall and reinstall the app and hopefully it will solve itself. If that didn’t solve the error and you can’t wait for an update, you can install Windows on a Mac with Bootcamp.
