Mac unable to start project in Studio only

When developing on Studio on my Mac, I am able to edit scripts and the workspace, but unable to test, both from a Play test and Local Server test launch. When starting the Play test button, the game hangs and I am able to still type in the scripts, but the Server and Client switch button isn’t functional (video attached). After a long delay (multiple minutes), the game shows a message about how the game is loading (photo attached). Occasionally, after the delay, the game will start successfully, but the communication (I’m assuming) between client and server takes an incredible amount of time and is unusable.


I have had Studio on this machine for about a year, but haven’t developed on it for almost 6-8 months, at which time it was working perfectly fine.

Apple M1 Pro 2021
32 GB
Sequoia 15.3.1

I have tried uninstalling and reinstalling studio. I’m suspecting it’s a port issue or network issue. I tried looking at a similar thread (Mac can't play the project in studio) but the fix didn’t work for me, as the port works on both the localhost hostname and also 127.0.0.1.

additional info:
Firewall disabled
Experience development is fine on my desktop windows machine
Every single place seemingly has this issue, including brand new ones

Interestingly, when my experience was configured for Team Create, it would take an immense amount of time to even open up, and fail to do so half the time. Disabling this fixed this, but I believe these issues are all related.

Hi,

Thanks for filing this issue. I have a few questions to help us reproduce this locally:

  • Have you tried to publish this game and test it? Does it run?
  • Would it be possible for us to look at the place file? If not, the Studio logs? You can share either in a private message.

Thank you!

I have just tried. What I did was I published from my windows machine. I then opened from my mac, and first tried to reproduction steps again and got the same issue. I then published to roblox from my mac. The publish was successful and the game is fine on live. (https://www.roblox.com/share?code=e78834410de57b42ad8bd1c60afe2622&type=ExperienceDetails&stamp=1741751765873). I will send the place file to you in a private message.

I tested it locally and was able to run the game without any problems.

Given that this is a unique issue to you, it is possible that your local Mac setup is corrupted, so one option is to try to locally reset your settings (back them up and delete them).

We could also look at your Studio logs if the above fails.

I’ve tried resetting them before, but it’s possible I haven’t done it correctly. I’ve attached the log files.
0.663.0.6630659_20250312T044147Z_Studio_a0fc1_last.log (425.1 KB)

The only thing I did during this run was open the file, press play, wait for it to pause and wait, then closed it.

Thank you, I added the log to the ticket, and we’ll continue to look at this.

Just a heads up, i decided to wipe my mac and the issue is resolved.

Thanks for the heads up! This definitely sounds like a Settings gone wrong, then. I’ll make a note to the ticket that the Settings got corrupted.
