I want to explore the new system. So I upgrade my MacBook Pro to macOS 26.0.1. However, after running on the new OS a noon, I found that my MBP runs slower and slower. This issue hasn’t appeared before the update. Why this trouble happens? How can I make my Mac run faster?
Upgrades may leave old system caches, logs, or temporary files that bog down performance. I suggest you clean up your Mac. It is hard for us to manually find system logs, cache files, and other junk files on a Mac.
So, I suggest you use a Mac cleaner. I’ve used iBoysoft DiskGeeker. This all-in-one disk management tool supports scanning user cache, user log, app cache, trash, and other types of junk files on your Mac for one-click deletion. Then, your Mac will quickly get more free space and run faster.
- Download iBoysoft DiskGeeker for Mac and install, and open it on your Mac.
- Select your user data volume (usually called Macintosh HD - Data or macOS - Data) and click Scan next to the Clean Junk function.
- Wait for the scanning process to end, select your unwanted files, and click Clean to directly delete them.
New OS versions often occupy more RAM and CPU. If your MacBook is older, Tahoe might be pushing it harder than it did with the previous version.
Besides, some apps aren’t optimized for Tahoe, which can cause slowdowns or even freezes. Go to the App Store to check if there are any updates available for your apps.
