celeste wont launch

[elder maple]

celeste worked fine on my laptop a week ago, but wont launch now; it just gives me this popup

i havent updated anything or changed any settings

and this is just a stock celeste install

im not really sure what to do so any help would be appreciated <3

what’s your hardware?

[elder maple]

the laptop is an old macbook pro

model number a1398

its currently running windows 10

[elder maple]

this is the part that really baffles me; nothing has changed about my setup but it just. doesnt work now

the issue persists through reboots and reinstalls of celeste

[dusty swallow]

Maybe check your Windows update history.

[elder maple]

nothing

If you haven’t done it yet, try using Everest to launch Celeste

Hopefully you mean olympus

It does sound like a graphics driver issue, do you see graphics cards listed in Device Manager?

Otherwise you could try switching to opengl

[rigid marlin]

To switch to the version of Celeste using the FNA framework, go to your Steam properties for Celeste and switch to the opengl beta.
If you have Everest, you will need to reinstall it after doing this.

[elder maple]

i dont know what that is

[silver lichen]

idk too

I only know olympus

[worldly wind]

mac can do that..?

Try running celeste on macos

[elder maple]

i dont have that installed

like i said though, i havent changed anything since last week when it worked

[elder maple]

ill check this as soon as im able 👍

[halcyon jewel]

okay… I mean olympus. Just try fna instead of xna maybe it’ll work

[elder maple]

whats olympus

will do with the fna vs. xna thing

[dusty swallow]

Olympus is the Everest installer and mod manager.

You should have downloaded it and used it to install Everest.

The tutorial should help

You don’t have to download strawberry jam if you’re just playing vanilla for now

[elder maple]

this fixed the issue

[elder maple]

it will help the issue if it happens in the future ?

[halcyon jewel]

It’s pretty much the same method. Olympus just makes the game run in fna

[elder maple]

okay

thank you

[worldly wind]

Not sure where you got that information from

[halcyon jewel]

when i first play modded celeste it causes me serious screen tearing problems.

Then I saw a reddit post when I'm searching for a solution saying something like olympus uses fna that works differently comparing to xna and that's probably the reason why there's issues.

I know little about game development. I’d be happy if you can correct me if I said anything wrong.

[boreal briar]

Everest makes the game run in FNA yes

Because it upgrades a bunch of stuff, notably .NET, and XNA has been abandoned by Microsoft long ago

Olympus just installs Everest and launches the game Once Everest is installed, running the game through Olympus or through Steam is no different (except if you enabled "use OpenGL" in Options & Updates 🤷‍♀️)
