2011 Macbook Pro GPU failure fixed but...

Then you just download EtreCheck and run the app. Then within EtreCheck once it finishes scanning your system you click on "Share Report" to copy the report for pasting into the "Additional Text" field here.

We can't read all the critical diagnostic info. Here is how to post the report:

Run EtreCheck, select “Report" from the left-hand pane (scroll down to the bottom of that pane to find):

When its report displays, click the "Share Report" icon from EtreCheck’s toolbar and then "Copy report” from the resulting dropdown.

⚠️ Please DO NOT highlight the text in the report before using Etrecheck’s “Copy report” command—that will garble the formatting and make the report slower and harder to evaluate.

NOTE: Changes in late 2018 to the forum software require you use the “Additional Text" icon (see example below) to embed the report into a post:

Paste the report into the resulting “Additional Text” window:

Your post is confusing then. The title & first line of the post says you fixed the GPU issue and the system is just running slow. This implies the laptop is working fine except for the slow performance.

If you are still having GPU issues, then check out these links to try and force the laptop to use the Intel GPU:

Your SSD drive is way too slow. it is all really small. But it does not have TRIM enabled, which might speed it up. If that does NOT speed it up, it may need to be replaced with a 500-ish GB or larger SSD drive.

sudo trimforce enable

Now any New deletions will free up space on the drive. But to release all the saved deleted data, you need to restart in Safe Mode, (hold shift at startup) and wait while it does an about five minute disk repair.

To check the health of the SSD try running DriveDX and posting the report here using the "Additional Text" icon which looks like a piece of paper. The trial version of DriveDX also allows you to run the SSD's internal short self-test diagnostic.

Click on the "Share Report" option at the top of the EtreCheck app and choose copy. Then click on the "Additional Text" icon which looks like a piece of paper.
