All operating systems, Mac, Windows and anything else, are out-of-the-box suppressed, invasive and bloated. Especially when pre-installed with a notebook, desktop, tablet or even phone.
Some reasons why...
Software you don't want or need is included and can grow like a cancer.
The user interface and experience is lousy and way more cluttered than necessary.
There are many unnecessary system and memory resource robbing things happening in the background that can be disabled or removed entirely.
Your privacy is the LAST thing anyone is concerned with. In fact, operating systems and software of all types invade your privacy unless dealt with.
Antivirus software like Norton, McAffe and Kaspersky for example, are huge applications that need to be tamed to do their job without affecting a systems performance. In fact, you don't even need to use or spend money on these clumsy products year after year and can still remain secured for free with software that is much lighter on system resources, is included in the operating system and does the same or a better job of taking care of viruses and intrusions if used and setup properly.
Whatever device you are on is performing worse than it is capable of due to some of these reasons and therefore you're not only at risk of losing data or being hacked, you're not even getting the performance and security you paid for and expect. Even the cheapest, slowest computers manufactured today are far more powerful in speed and capacity than the average user understands or needs. Because of this, people overspend on computers wasting their money and never get to enjoy the full experience and performance these devices are capable of delivering.
The next time you find yourself standing in front of a row of laptops or desktop computers somewhere trying to decide what to purchase know this... Every unit you are looking at is basically housing the same major components by the same manufactures. The only true difference in quality is the chassis and motherboard that all things such as hard drive, memory chips and processors are attached to.
Of the common types of components installed by these major manufacturers, there are brands that are better than others. That's part of the "no techno mumbo-jumbo" you will be spared of here. Enough of that.
Everyone you encounter that builds, sells, services or whatever else with computers will seem like they really know their stuff. Some do. Most don't and may convince you to let them handle your sale, build or service. It's happening right now. Treat your computer exactly the same way you do your purse, wallet or briefcase. Today computers have unfortunately become most people’s livelihood, entertainment, personal memory capsules, financial hubs and more. So just be wise and choose who accesses your device and data carefully.
The computer industry is, and has always been a place where the average consumer has and continues to be targets and victims of overpriced hardware, overcharged service and vulnerable to scams by a lot of companies and individuals that can make a quick buck without any conscience or concern for someone's data or privacy. It's hated when a new client arrives after being somewhere for service and told that their hard drive was corrupt or dead and needed to be replaced or wiped to fix a problem which resulted in the total loss of their data such as important or crucial documents, personal photos, or even replaceable things like music or movies that took long to accumulate. When they have to be told there was a simple fix, or the original hard drive is still installed and wasn't replaced, well, you get the point. That has been encountered many times over the years. There is never an excuse to destroy someone's data. Again, be wise and choose carefully.
Lastly, this can go on here forever but will be left at that for now. More will be added to this section in the future when the inspiration calls.
