iMac 27” Late 2012 (GTX 660M) — how is macOS Sequoia performance with OCLP?

Hi everyone,

I have an iMac 27” Late 2012 with the following specs:

• i5 2.9 GHz

• 32 GB RAM

• NVIDIA GTX 660M 512 MB

• SSD

Currently running macOS Sierra.

I’m thinking about installing macOS Sequoia using OCLP and wanted to ask:

• How is overall performance (UI smoothness, lag, stutter)?

• Is the GTX 660M properly accelerated or are there graphical issues?

• How are temps and fan noise compared to older macOS?

• Is it usable as a daily machine (Safari/Chrome, YouTube, etc.)?

Would really appreciate real-world experiences, especially from people with this GPU.

Thanks!
