Can't Install Engine to External Hard Drive? (Mac)

Help, I don’t have enough storage on my Mac… And there doesn’t seem to be an option to install engine to an external hard drive. It just says “not enough storage”.

Hi ,

You can only install engine on boot drive of your mac, but once you have it there you can move it to an external drive by setting up a symbolic link, as described here:


You can also save all projects you create to external drive, which should help as well.

Hope that helps!

Thank you

In code, am i supposed to replace something with my hard drive name? Sudo mv /Users/Shared/UnrealEngine /Destination/Location/ Didn’t work by itself… (I did do second command to…)

It looks like you have a space between UnrealEngine and /Destination. That looks like a problem with wiki page, which I’ll see if we can get fixed.

Similarly, make sure there is no space between Shared and /Users in second terminal command.

Sorry for picking up this topic again, but I got a quick question. When running Unreal Engine from an external Hard Drive (assuming using USB 3.0), does it greatly increase power/performance of engine or does it still perform very fluent? I will definitely try it, but maybe someone has an answer before I get to do it (probably can try it by tomorrow). Thanks in advance :slight_smile:
