Newer macOS runs slower on Intel (undeniably) – on purpose or "accident"?

Look at Activity Monitor report when it's overloaded to see what's busy.

MacOS and apps have many kinds of background activity which present large transient loads, for example Spotlight indexing and photo library facial scanning.

Do you have a browser or other app infected with a crypto-miner or other malware?

If you create a new user and sign in using only that new user, do you see the same overload?

Are you running an unsupported Mac for Tahoe via OCLP? Thar be performance hazards. Search Macrumors "unsupported" forums.

Tahoe seems to have slowed down the OS a bit but I don't think it is as extreme as you're seeing here. I don't have any intel chips to test with myself but personally I'd try running some benchmarks both CPU and GPU to see if your scores match up with other people running your hardware. After that maybe check to see if you're throwing errors in your console. Maybe it'll lead to a hint. It seems like a bad bug somewhe…

I'm confident it isn't purposeful. But no hardware errors can be found. Virgin install Tahoe: grinds from 74-C up to 100-C within a minute and then throttles. Virgin install Sonoma: runs fine. No temperature change of note. This isn't indicative of a hardware problem.

Nothing in dmesg? Maybe try to put some dtrace probes into the sys calls and see if anything is suspicious. Let spotlight index for a day or so first.

Would guess not intentional.

Apple has little financial incentive to spend money on testing new software beyond the minimal on intel macs.

Unlike older iphones where apps are being bought in large volumes so they make money, a lot of Mac apps are web based or downloaded directly/via home brew. Its only apple music and tv etc they would take care not to break

So Apple have an incentive to maximise the number of older iphones in use to sell apps and so subscriptions but less for Intel macs

As long as you use proprietary OSes, do not ever update past what has come with the hardware(reinstall back to it if needed). That's why there are still machines using windows xp still in use today. That's where you will get the fastest/best experience. If your mac came with Catalina(10.15.1), stay there and run that mf into the ground. Never shut it down(you don't know if it will start back up if you do) and never u…

This is terrible advice that would cause a TON of people to become exposed to patched vulnerabilities.

One man's terrible advice is another man's amazing advice.

You either use libre software and have great speed while also having patched vulnerabilities(you can DIY if nothing else).

Or you can use proprietary software and never update to get good speed.

Or use patched proprietary software and have poor performance.

But never all three. You just can't have everything in this world.
