MacBook Pro 2019 performance regression after Tahoe update

Hi. This is a macbook pro 2019 16".

I was getting 43.2k score on geekbench for GPU/meta on sequoia. now it is 8.8k on tahoe.

CPU benchmark is about 0.1k higher than sequoia.

Essentially, i traded my desktop for this machine on the hopes that tahoe would not be offered to intel macbooks. i'm not fond of updates.

The computer is very sluggish now. Is there an official statement that tahoe is indeed the last ever intel upgrade? Links to apple.com articles should do. I don't think this machine can handle more unnecessary upgrades/slowdowns.

? it seems hyperbolic assessment out of the gate.

Sure, point updates will roll out over the entire year—addressing known issues.

< re: 2019 >

I am running an Intel 2019 16" MBP and I have no major issues...

my advise—

unplug all non-essential peripherals when testing

Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus

all known to cause issues on the macOS

To trouble shoot further you can:

—A SafeBoot Start up your Mac in safe mode - Apple Support will sort many anomalies

Does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, third party system modifications and system accelerations are disabled temporarily.

Login and test. Reboot as normal and test. Caches get rebuilt automatically.

This test will tell you if third party interference; most extensions etc are not loaded in safe boot mode.

—Test issue in another user (or guest user) account Change Users & Groups settings on Mac - Apple Support

This will tell you if it a universal issue or isolated to your user/admin account. 

***wireless keyboard with rechargeable batteries— connect the charging cable, this will make the wired keyboard successful Safe Boot your Mac.

none of these are GPU related.

Also, I am not looking for a solution. I just need some documentation that 26.xx is the last major release for intel.

if you say so.

Yes it is the last major Upgrade for that machine. the 2019 MBP Intel was one of oldest / last of Intels to make the cut.

Intel is being phased out.

State of the Union at WWDC, Apple just announced that macOS 26 Tahoe will be the last release of macOS that supports Intel. WWDC25 - Apple Developer

Intel Macs will not be supported on macOS 27; Apple confirmed that macOS 26 Tahoe is the final version to support Intel-based machines, and macOS 27 will require Apple Silicon.

Installing a new version of MacOS changes over 35,000 files. It will require at least several hours of 'awake but not too busy' time to update the Spotlight index, among other routine tasks.
