How to improve MacBook performance after removing AI apps?

After removing AI apps apart from the one I use I still have low performance ("below average") as indicated in my EtreCheck Report.

you could finish implementing the items I noted before on your previous thread;


Poor Mac performance: heavy RAM and CPU u… - Apple Community



and you have NOT completely removed OpenAI.

You are still using backBlaze.

Your Time Machine backups have not completed since march 14


and your original M1(plain) has a slow drive:

Write speed: 2812 MB/s

Read speed: 2101 MB/s

... compared to the MacBook Pro models available today.


And you are running a Lot of stuff all at once and have only 16 GB RAM.

If you add more memory load, that will soon overflow onto the boot drive, which is comparatively slow.

Hello,


I deleted Backblaze's online backups and restored my previous iCloud preferences. I reactivated Time Machine backup. I used Terminal to purge unnecessary files.

My system (MacBook Pro M1, 16 GB RAM, 1 TB SSD) now appears to be operating within normal parameters. No evidence of hardware degradation or storage performance issues could be detected (SSD read/write speeds exceed 2 GB/s; disk health 100%; ~300 GB free space available). The “System Data” is currently elevated at approx. 100 GB, including 59 GB purgeable. The lower-than-normal performance rating is apparently attributable to a transient, resource-intensive background workload initiated by recent iCloud resynchronization and large-scale file reprocessing. The system is concurrently performing Spotlight reindexing (15 GB index), iCloud file synchronization (via cloudd, fileproviderd, bird), and metadata/PDF rendering operations (CGPDFService) across a dataset of approximately 10,700 PDF/EPUB files. I expect these processes to be completed within 24–72 hours. 


Thanks again for your helpful suggestion.

What are these apps? What are these intended for?


Restart your Mac:

Have uninstalled these apps, restart your Mac.


Remove any existing caches:

Caches are created for Terence of app usage so that apps open quicker and more efficiently.
