Does apples purposely slows your Macbook?

When you Factory Reset your computer, are you restoring from a backup? If that is the case, it may be returning your Mac to the state it was before including bringing back any problematic apps that are slowing your computer down. To avoid problems, do not install any of these types of software:

• Cleaners
• Optimizers
• AntVirus
• VPN

To find out what may currently be causing problems with your computer post the EtreCheck report here using the Additional Text option when posting. This will detail that app that are launching on startup and also show what is consuming the valuable CPU cycles causing your fans to come on. It also shows if you are running out of RAM and using swap files that will slow things down. The report contains no personal information.

Using EtreCheck - Apple Community

Some videos on YouTube suggest getting a paid third-party app to fix the problem, but I find that ridiculous.

Your instincts serve you well. You can't tell how much any YouTuber gets paid to post drivel.

Most software slow-downs in Macs are due to useless:

• anti-virus software
• so-called "cleaning" apps
• client-side VPNs ( the ones the spend $millions$ on TV adverts)
• torrent software

However if those are running up the heat inside your Mac, the system is designed to clock back the process in high-heat conditions to save its brain.

Watch videos and video-conferencing are NOT trivial tasks. Both work the CPU and GPU very hard.

External monitors are very high-draws devices. You should not use clamshell mode (lid closed while using an external display) due to how it compromises the cooling capability of a Mac notebook (and most other brands). Conspicuslous in the last year, Apple have removed all previous references to clamshell mode from their knowledge base. It seems to me that clamshell mode runs counter to support advice posted in this Apple article on temperatures, specifically this:

As this is commonly as software issue, and if you wish a data-driven evaluation in this setting where we can neither see nor touch your computer, please post an EtreCheck report. We can usually quickly and within the limitations of these forums help you determine what issues are at play without our playing a protracted game of "20 Questions" with you that could go on for days. 

EtreCheck Pro is available here:

The free version will do nicely for this purpose, although the app is worthy of our financial support.

We can see hard data about drive performance, software issues and interferences, and RAM usage. Etrecheck is the development of a long-serving and trusted ASC contributor. It issafe, and only a reporting app, not a "fix-it” app, expressly for displaying information in these forums that helps us help you remotely. It will not reveal any personal or secure information.

The report is designed to be posted here. Our senior contributors have read thousands of these and can find important indicators that are significant yet are not obvious to new users.

Please see this excellent user tip on how to post long text reports like EtreCheck's into a forum response:

How to use the Add Text Feature When Post… - Apple Community

Intel i9 runs stupidly hot.

If this MacBook Pro is at all memory-constrained, a chunk of that heat and that slowness will come from shuffling apps and app data between main memory and main storage, too.

Please download and run EtreCheck, and share the generated report to the clipboard. Then open a new reply here, and press the Additional Text button that looks like a printed pate to get a text input box big enough to paste the hardware and software configuration report here, and paste and post that report here.

You underestimate the resources necessary for editing RAW. Macs that come with only 8GB of RAM have barely enough resources to do any video editing. RAW is also very memory intensive. I recommend keeping your hard disk at least 15% free at all times. Don't backup to the Cloud unless you have high speed upstream broadband (100 Mbps or higher), and only backup when you aren't doing production. Don't use any optimizers either:

The NAS may be slow because of its own network and port configuration. Unless you sharing the NAS with multiple computers, NAS may actually be slowing you down over having a straight thunderbolt external storage.
