Because of a PC hardware failure, I got out my older 2018 intel-based Mac running Sequoia, which I used to run UE 5.5 on. After installing the Launcher, I find that I cannot install any version of UE. When I press the Install button, nothing happens, regardless of the version of Unreal Engine. Tailing the Launcher’s log, nothing is being written to it when I press Install.
I’ve been building the engine from source today, but I am sure I’m going to run into trouble with the Launcher again when I want to install some of my purchased plugins.
Has anyone got any suggestions for how I can get the Launcher working once more? I suspect it something to do with the intel/M chip changes, but I don’t know how I would get an older version of the Launcher to try out.
hey @Corysia, this sounds like it could be related to mac OS Sequoia, a few others have reported similar launcher problems on that version. Since your install button does nothing and log stays completely empty, that suggest the launcher isn’t even reaching out to the network, potentially something silently blocking it like a firewall or security tool on your mac?
Before reinstalling it might be worth quitting the launcher completing and finding its cache and vault folders, and then doing a clean reinstall. Given you’re already building from source today, it might also worth checking if a fresh source build bypasses the launcher issue entirely for now since that at least gets you working whilst the launcher problem gets sorted separately.
Hope that helps, let me know how you go!
Thanks for the reply. I am not entirely sure what fixed it. While I was building a release build so I could purge all the source and save some disk space, I gave the launcher another try and it worked. I am wondering if it was related or if there was some other behind-the-scenes issue going on, either at my end or Epic’s servers. Or the Launcher may have been updated. I seem to recall my Desktop received a Launcher update during this time frame.
Regardless, it’s now working and I was able to pull down 5.7.4, which is the last version that will run on this old Mac. Apparently, metal support was removed in 5.8, so intel Macs are S.O.L.
My plan is to put Windows or Linux on here once Sequoia is no longer supported by Apple. I need to limp along a little longer before I can buy a replacement.
