I recently had my Mac repaired, and when it came back, it was wiped and set to the newest OS, Tahoe 26.2. Before that, I was using Sequoia. I thought my Time Machine backup would help me restore it, but it didn't work this time. Now I'm stuck with Tahoe, which is super sluggish and has broken a bunch of my apps. I want to downgrade back to Sequoia without having to wipe everything and start over with a backup. Can anyone walk me through the steps to downgrade?

Hey! Just to clarify, since you have an Intel Mac, you'll indeed have to wipe your drive. You can download the Sequoia installation file from Apple’s site if you have access to it, or check if you have it on a USB installer if you made one back in the day. Just make sure to back up anything important before wiping. It might take some time, but it’ll be worth it to get everything running smoothly again!
To downgrade your Mac, you'll first need to check whether you have an Intel or Apple Silicon model. Since your Mac is 6 years old, it's likely Intel. Unfortunately, system files aren’t part of the Time Machine backups anymore, which means you'll need to erase your internal storage. Then, you can use a bootable installer to reinstall Sequoia. Apple’s support page has the steps for creating a bootable installer, which you can find [here](https://support.apple.com/en-us/101578). Good luck with the downgrade!
